Please help this question I need all of them

Step-by-step explanation:

7x+3(-2)=14

7x-3x2=14

7x-6=14

(7x-6)+6=14+6

7x-6+6=20

7x=20

7x/7 = 20/7

x= 20/7 or 2.85714285714

Answer:

Cost for 6 miles is 6 dollars.

Step-by-step explanation:

The equation would be 2+1.50x6 then you multiply 1.50 by 6 which gives you 4 and add 2 which would sum up to $6.00

Answer:

y=1 1/2 (fraction)

or

y=1.5 (decimal)

Step-by-step explanation:

We want to get y alone, so we need to get rid of the 1/2 in front of it. To do that we can multiply each side by 2 since 1/2 + 1/2 = 1.

3/4= 1/2y

multiply each side by 2

To multiply 3/4 by 2 you need to multiply the numerators and then multiply the denominators

2•3=6 & 4 • 1 =4

6/4

simplify

y=1 1/2

(If you need it in decimal form it would be y=1.5)

Answer:

C. From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

Answer:

C

Step-by-step explanation:

y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.

Answer: Airplane A by a scale factor of 1.02

Step-by-step explanation:

Airplane A: 1273/4=318.25

Airplane B: Rate is the slope of equation, 621/2=310.5

So,

318.25/310.5=1.0249

Airplane 'a' is faster than airplane 'b' by a factor of  1.03 times.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, An airplane 'a' traveled 1273 miles in four hours.

∴ The airplane 'a' traveled (1273/4) = 318.25 miles per hour.

For airplane b y = (621x)/2 + 0b represents the rate of speed over the same four hours

∴ The rate of change per hour for airplane 'b' is (621/2) = 310.5 miles.

So, airplane 'b' is faster than airplane 'a' by a factor of (318/25/310.5) = 1.0257 = 1.03 times.

Step-by-step explanation:

Simply multiple the values listed

[tex]3.12 \times {10}^{5} \\ \times 6 \times {10}^{7} [/tex]

You can just multiply the values and keep it in scientific notation. No reason to multiply all if it to find the answer.

[tex]18.72 \times {10}^{12} [/tex]

Now we have to put it into scientific notation, simply move the decimal to the left by 1 and add to the exponenet by 1.

The value of x when h(x) =-3 is 5.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

h(x) = -x + 2

Now, we have to find the value of x when h(x)= -3

So, h(x)= -3

-x+ 2= -3

Now, Subtracting 2 from both side

-x+ 2 -2= -3 -2

-x = -5

x= 5

Hence, the value of x is 5.

Answer:

boys = 150

girls = 350

Step-by-step explanation:

I'm not sure what a tape diagram is, but I can get the answer.

Let b = boys

Let g = girls

3/7 = b/g

3/7 = b/(b + 200)

3(b + 200) = 7b

3b + 600 = 7b

600 = 4b

b = 600/4

b = 150

g= 150 + 200

g = 350

Answer:

a) 53%

b) 12%

Step-by-step explanation:

you need to use the equation given

y = -6.83x + 108

x is the rank

y is the probability of winning 1st game

a) for rank 8th or x=8

y = -6.83(8) + 108 = 53.36 or 53%

b) for rank 14th or x=14

y = -6.83(14) + 108 = 12.38 or 12%

Answer:

y = 3x-5

Step-by-step explanation:

this is becuase the y-intercept of these points falls to around -5 (a point actually crosses the y axis at -5)

the gradient of these points is too steep to be x and the slope is not negative - therefore the slope must match closest to 3x.
