Solve the system of equations.
y = 6x + 13
y = 2x + 1

Answers

Answer 1

Answer:

x=-3. y=-5

Step-by-step explanation:

Equating both equations,

6x + 13 = 2x + 1

6x - 2x = 1 - 13

4x = -12

x = -3

Plug in the value of x in the given first equation,

y = 6* (-3) + 13 = -18 + 13 = -5

Answer 2

Answer:

{y,x} = {-5,-3}

Step-by-step explanation:

System of Linear Equations entered

y - 6x = 13

 y - 2x = 1

Graphic Representation of the Equations

-6x + y = 13        -2x + y = 1  (attached)

Solve by Substitution

y = 2x + 1

(2x+1) - 6x = 13

   - 4x = 12

4x = - 12

    x = - 3

  y = 2x+1

   x = -3

 y = 2(-3)+1 = -5 (final answer)

hope it helps you!

2nd statement is correct.

finding the average hours worker A does and then the average amount paid i got

average hrs = 22.6 hrs and average amount paid= $250

so comparing them to one hr i got the amount paid to worker A in one hr which is $1.11

so compare to worker B earnings and find the true statements

Step-by-step explanation:

Environmentalists estimate an annual population decrease of giraffes in the wild of 3.5% due to development. This can be modeled by the function p(x) = 140,000(0.965)^x, where x is the number of years of tracking the populations. Conservationists have developed a sanctuary that has shown the ability to increase the population by 0.85% per year. The increase can be modeled by the function S(p) = p(1.0085)^x.


Which function represents S(p(x)), rounded to the nearest ten thousandth?

A. S(p(x)) = 135,100(0.9732)^x

B. S(p(x)) = 135,100(1.9735)^x

C. S(p(x)) = 140,000(0.9732)^x

D. S(p(x)) = 140,000(1.9735)^x

Answers

Answer:

S(p(x)) = 140,000(0.9732)^x

Step-by-step explanation:

Given the population functions:

ENVIRONMENTALIST: decline by 3.5% annually

p(x) = 140,000(0.965)^x

CONSERVATIONISTS: Increase by 0.85% annually ;

S(p) = p(1.0085)^x

Formulate S(p(x)) rounded to the nearest ten thousand

p(x) = 140,000(0.965)^x

S(p) = p(1.0085)^x

S(p(x)) = p(1.0085)^x

Where p(x) = 140,000(0.965)^x

S(p(x)) = 140,000(0.965)^x(1.0085)^x

S(p(x)) = 140,000(0.9732025)^x

S(p(x)) = 140,000(0.9732)^x

If f(x)=4^x-8 and g(x) =5x+6, find (f+g)(x)

Answers

Answer:

C

Step-by-step explanation:

(f + g)(x) = f(x) + g(x), then

f(x) + g(x)

= [tex]4^{x}[/tex] - 8 + 5x + 6 ← collect like terms

= [tex]4^{x}[/tex] + 5x - 2 → C

(f+g)(x)=f(x)+g(x)=4^x-8+5x+6=4^x-2+5 or 4^x+5x-2 answer is C

You go to the store and notice the people standing in line. 7 adults and 4 children. If this ratio stays the same and there 55 people in the store. how many would be children?​

Answers

Answer:

20

Step-by-step explanation:

7+4=11

11*5= 55

4*5=20 :)

The number of children and adults will be 35 and 20, respectively.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

You go into the store and observe the folks in queue. There are 7 adults and 4 children. If this ratio remains constant and there are 55 people in the store.

7x / 4x = constant

Then the equation is given below.

7x + 4x = 55

11x = 55

x = 11

Then the number of adults is given as,

7x = 7 (5) = 35

Then the number of children is given as,

4x = 4 (5) = 20

The number of children and adults will be 35 and 20, respectively.

More about the ratio and the proportion link is given below.

find the slopes of the linear equations

Answers

Answer:

m is the slope.

b is the y intercept.

slope intercept is in the form: y = mx + b.

y - 4 = 3 (x - 2) [m = 3] [slope is 3]

y = 3/4x - 7 [m = 3/4] [slope is 3/4]

y + 8 = -6 (x - 1) [m = -6] [slope is -6]

y = -5x + 10 [m = -5] [slope is -5]

4x + 5y = 20 [m = -4/5] [slope is -4/5]

Explanation:

For all of these equations, make sure they are all in slope intercept form by isolating y completely, and getting it on the left side of the equation.

y - 4 = 3 (x - 2) → y - 4 = 3x - 6 → y = 3x - 2 → y = mx + b.y = 3/4x - 7 → y = mx + by + 8 = -6 (x - 1) → y + 8 = -6x + 1 →. y = -6x - 7 → y = mx + by = -5x + 10 → y = mx + b4x + 5y = 20 → 5y = -4x + 20 → y = -4/5x + 4 → y = mx + b

Anne owns a used car lot and in order to get cars to sell, she buys used cars at an
auction place. It costs $200 to attend the auction and she buys used cars at
$2,000 each. Last Tuesday, she purchased 10 cars. Which of the following
functions correctly represents this situation in function notation?
f(x) = 10x + 200
f(x) = 200x + 2,000
f(x) = 2,000x + 10
f(x) = 2,000x + 200

Answers

Answer:

It would be 2,000x+200

Step-by-step explanation:

okay it costs $200 to attend so that's a cost you are going to have to pay regardless. The $2,000 depends on how many cars you buy. So it would be 2,000 (times how ever many cars you buy) plus the $200.
