2x + 4y = 12 y = x – 3 What is the solution to the system of equations?

1 answer:

8 0

2x+4y=12
y=x-3

Since we know what y equals, we can plug this into the first equation:
2x+4(x-3)=12
We can then distribute:
2x+4x-12=12
And solve for x:
6x-12=12
6x=24
x=4
We can then plug x into the second equation and find y:
y=x-3
y=4-3
y=1

Therefore x=4 and y=1

Schach [20]

Answer:

$\boxed{v=300}$

Step-by-step explanation:

<em>Hey there!</em>

To find v we’ll set up the following,

v ÷ 5 = 60

To get v by itself we’ll do

5*60 = 300

v = 300

The school cook made 30 pounds of potato salad for the school picnic. How many servings is this if each serving is 1/4 pound?

iren2701 [21]

120 servings.
You do this by multiplying 30 by 4 (because each pound can make 4 servings as represented by 1/4 pound) Hope you understand I'm not good with explaining.

The vertex of this parabola is at (2, -4). When the y-value is -3, the x-value is -3. What is the coefficient of the squared ter

lyudmila [28]

Answer:

The squared term is 1/25

Step-by-step explanation:

The parabola equation in the vertex form is

$y = a \times (x - h)^2 + k$

where point (h,k) is the vertex and a is the squared term. In this case h = 2 and k = -4. On the other hand, we know that y = -3 and x = -3 are in the parabola. Replacing these values in the formula gives

$-3 = a \times (-3 - 2)^2 - 4$

Solving for a

$-3 + 4 = a \times (-5)^2$

$1 = a \times 25$

$a = \frac{1}{25}$
