Y = -2x + 19 y = x + 7

Mathematics

y = -2x + 19

y = x + 7

Since both equations are solved for y, set them equal to each other and solve for x.

x + 7 = -2x + 19

Add 2x to both sides.

3x + 7 = 19

Subtract 7 from both sides.

3x = 12

Divide both sides by 3.

x = 4

Now substitute 4 for x in the first original equation to find y.

y = -2(4) + 19

y = -8 + 19

y = 11

Answer: x = 4 and y = 11

System of equations:

y=-2x+19

y=x+7

The intersection point for this is <em>(4,11)</em>.

A dairy cow can produce up to 2000 gallons of milk every 365 days. At this rate, a cow can produce x gallons of milk in 500 days
Mariulka [41]

First I cant understand the choices, because on how you type so I will jus provide the answer for you. First the amount of milk produce is proportional to the number of days so

2000 = k(365)

K = 2000 / 365

So to solve for x

X = ( 2000/365) 500

<span>X = 2740</span>

Evaluate each expression using the values m = 7, r = 8, and t = 2.
user100 [1]

So I'll walk through the first 2. Then please try the other ones and let me know if you run into more problems.

5m-6

If m is equal to 7, then replace m with 7.

5(7)-6

5x7=35 so the expression is now 35-6. Solve.

35-6=29

So that was the first one.

4m+t

We just do what we do with the first problem.

4(7)+(2)

4x7=28 so the expression is 28+2.

28+2=28

---

hope it helps

p.s. When there is subtraction, add. When there is division, multiply to cancel that out. When there is multiplication, divide to cancel. etc.

Given the function f(x) = 4(x + 3) -5, solve for the inverse function when x=3
daser333 [38]

Answer: Your answer would be -120

Step-by-step explanation: Remove Parentheses (3 + 3) add them together and make it 6 and plug in the 6 into the equation. -4 x 6 x 5. Then, you multiply the numbers together and get -120. There is no inverse for -120 since both sides aren't equal.

I hope this helps you!!
