Which equation can you create with the given information? m=6, b=-2 A.) y=6x-2 B.) y=6x+2 C.) y=2x+6 D.) y=-2x-6

Answers

Step-by-step explanation:

Hey there!

Your answer is Option A.

Check all:

A. y = 6x-2

Comparing the equation with y = mx+b, we get;

m= 6

and b= -2

B. y= 6x+2

Comparing the equation with y= mx+b, we get;

m = 6

b= 2

C. y = 2x+6

Comparing the equation with y= mx+b, we get;

m= 2

b = 6

D. y= -2x-6

Comparing the equation with y= mx+b, we get;

m= -2

b= -6

Therefore, Option A is correct answer.

The graph shows the linear parent function . Which statement best describes the function?
A. The function is negative when x<0 and also when x>0
B.the function is never negative
C.the function is negative when x>0
D. The function is negative when x<0

Answers

Using function concepts, it is found that the correct option is given by:

D. The function is negative when x<0

How the sign of a function is determined?If the graph is above the x-axis, it is positive.If the graph is below the x-axis, it is negative.

In this problem, the graph of the function is the red line, and:

For values of x < 0, the function is below the x-axis, hence it is negative.For values of x > 0, the function is above the x-axis, hence it is positive.

Thus, option D is correct.

Max and his brother exercise together. Max does half as many sit-ups as his brother does during a workout. If Max's brother does between 100 and 150 sit-ups, which expression describes s, the number of sit-ups that Max does?
A. 0 ≤ s ≤ 50
B. 50 ≤ s≤ 75
C. 100 ≤ s ≤ 150
D. 200 ≤ s ≤ 300

Answers

Answer:C is the correct answer,

Step-by-step explanation:

50 ≤ s≤ 75 describes the number of sit-ups that Max does so option (B) will be correct.

What is inequality?

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Max does "s" number of sit-ups then max brother will do "2s".

Now,

Given that,

Max's brother does between 100 and 150 sit-ups

So,

100 ≤ 2s ≤ 150

Divide by 2 into both sides

50 ≤ s ≤ 75

Hence " 50 ≤ s≤ 75 describes the number of sit-ups that Max does".

What is the purpose of the AutoSum feature in Microsoft® Excel? A. To automatically add all numbers in all cells in a workbook B. To add a list of numbers in a spreadsheet C. To put a list of numbers in order before finding the sum D. To estimate the total of a list of numbers

Answers

Answer:

B. To add a list of numbers in a spreadsheet

Step-by-step explanation:

AutoSum feature in Microsoft Excel is used to automatically sum up a range of numbers within a horizontal row or vertical column without having to input a formula.

When a range of numbers are selected within a row or column, clicking on AutoSum will sum up the numbers in the adjacent empty cell. For example, if you wanted to add the values of cells between B1 and B10, highlight cells B1 through B10 and click the AutoSum button . The sum of B1 to B10 will be given in B11.

In Excel 2010 and later, the AutoSum feature is on the Home tab, in the Editing section.

2 step equations: solve the equation below:
m/5+9=11

Answers

Answer:

m=10

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    m/5+9-(11)=0

                 m

Simplify   —

                 5

  m          

 (— +  9) -  11  = 0  

   5

Adding a whole to a fraction

Rewrite the whole as a fraction using  5  as the denominator :

           9        9 • 5

   9 =  —  =  —————

            1           5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

m + 9 • 5                       m + 45

—————————  =  ——————

    5                                       5  

     (m + 45)    

 ———————— -  11  = 0  

          5

Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

             11          11 • 5

   11 =  ——  =  ——————

             1               5  

Adding up the two equivalent fractions

    (m+45) - (11 • 5)                                  m - 10

—————————————————  =  ——————

            5                                                          5  

    m - 10

 ——————  = 0  

        5

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

   m-10

 ———— • 5 = 0 • 5

      5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  m-10  = 0

Solve  :    m-10 = 0  

Add  10  to both sides of the equation :  

                     m = 10

m = 10

A restaurant manager states the number of customers that enter the restaurant is equal to 4

times the number of people that buy a hotdog from the hotdog cart plus 11. The manager also

states that the number of customers that enter their restaurant is equal to 1 times the number of

people that buy a hotdog from the hotdog cart plus 38. What number of people buying a hotdog

from the hotdog cart across the street makes the equation 4x + 11 = 1x + 38 true? Round

your answer to the nearest whole number.

Answers

Answer:

9

Step-by-step explanation:

No of customers that enter the restaurant is equal to 4 times the number of people that buy a hotdog from the hotdog cart plus 11.

The number of customers that enter their restaurant is equal to 1 times the number of  people that buy a hotdog from the hotdog cart plus 38.

The equation that shows the given condition,

4x + 11 = 1x + 38

x is the no of people

Taking the like terms,

4x-1x=38-11

3x=27

x = 9

So, there are 9 people buying a hotdog  from the hotdog cart.

The perimeter of a worksheet is 48 inches. The worksheet is 14 inches long. How tall is it?
inches

Answers

Answer: 10 inches

Step-by-step explanation:

1. multiply 14 by 2 to get 28.

2. Subtract 28 from 48 to get 20

3. Divide 20 by 2 to get 10

your answer is 10

Answer: 10 inches

Step-by-step explanation:

a worksheet is usually a rectangle

the formula for the perimeter of a rectangle is 2x + 2y

Lets say that x = the length and y = the height

it already gives you x = 14, so plug everything in to find y

P = 2x + 2y

48 = 2(14) + 2y

48 = 28 + 2y            plug in x = 14 and multiply

20 = 2y                    subtract 28 from both sides to get this

y = 10                       then divide both sides by 2 to get the answer

The function f(t) = |98.6-x|, represents a persons's variance from normal body temperature, where x represents a person's current body temperature in degrees Fahrenheit. Medical professionals say healthy individuals should have a variance of no more than 0.5 degrees Fahrenheit.

Answers

Answer:

98.1°F ≤ x ≤ 99.1°F

Step-by-step explanation:

Given the function:

f(x) = |98.6 - x|

Variance = 0.5

98.6°F - x = ± 0.5

Lower bound :

98.6 - 0.5 ≤ x

98.1 ≤ x

Upper bound :

x ≤ 98.6 + 0.5

x ≤ 99.1

Hence,

98.1°F ≤ x ≤ 99.1°F

180-80=100

100-10=90

90 divided by 15=6

explanation:

they’re supplementary angles (they add up to 180°), so we need to set up an equation by adding them to equal 180°:

15x + 10 + 80 = 180

combine like terms

15x +90 = 180

subtract 90 from move sides

15x = 90

divide both sides by 15

Answers

Answer:

310.73cm^2

Step-by-step explanation:

The expression for the total surface area is

SA=4πr^2

given that r=11cm

we want to substitute the value of r to solve for the area

SA=4πr^2

SA=4*3.142*(11)^2

SA=2.568*11^2

SA=2.568*121

SA=310.728

Therefore they need to cover a surface of 310.73cm^2
