Answer:

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable

Step-by-step explanation:

-3x + y = -24<br> y = 7x + 22

levacccp [35]

Answer:

first one: 8

second one: 3

Step-by-step explanation:

-3x + y = -24 |÷(-3x)

y = 8

y = 7x + 22 |-y

(y would be 1; the 7x moves to the other side.) meams:

7x = 21 |÷7

x = 3

Help and show steps pls

You can immediately see that the vertex is located at (-3,-2) and that the y-intercept is 7 or very close to 7.

The general equation for a parabola with vertex at (h,k) is

y-k = (x-h)^2, and from that and the given info, we get:

y-(-2) = (x-(-3))^2, or y+2 = (x+3)^2, or y = (x+3)^2 - 2.

Choose the slope-intercept form of 3x + 2y = 5. y = x – y = –x + y = –x + y = x –

Lyrx [107]

Answer:

$y=\frac{-3}{2}x+\frac{5}{2}$

Step-by-step explanation:

We are given that an equation

$3x+2y=5$

We have to find the slope intercept form of given equation.

We know that slope intercept form of an equation is given by

$y=mx+c$

$3x+2y=5$

$2y=5-3x$

$2y=-3x+5$

$y=\frac{-3}{2}x+\frac{5}{2}$

Hence, the slope intercept form of given equation is given by

$y=\frac{-3}{2}x+\frac{5}{2}$

lillianne made 6 out of every 10 baskets she attempted during basketball practice. if she attempted to make 25 baskets, how many

krok68 [10]

What is known?
She makes 6 out of 10.

$\displaystyle 10 \rightarrow 6$
$\displaystyle 25 \rightarrow x$

$\displaystyle x= \frac{25 \cdot6}{10} = \frac{5\cdot6}{2} = \frac{30}{2} =15$

Answer: If she attempted to make 25 baskets, she'd make 15 out of 25.

HTH ;)
