Answer:

Step-by-step explanation:

1). 7x - 2y = 5 , A = 7 , B = 2 , C = 5

2). 4x - y = 1 , A = 4 , B = - 1 , C = 1

3). 5x - 2y = 3 , A = 5 , B = - 2 , C = 3

4). 4x - 3y = 3 , A = 4 , B = - 3 , C = 3

5). 2x + y = 15 , A = 2 , B = 1 , C = 15

3x+4y=25<br> 3x-3y=-3<br> Following system of equations write answer as an ordered pair

Charra [1.4K]

$3x+4y=25\\
3x-3y=-3|\cdot(-1)\\\\
3x+4y=25\\
\underline{-3x+3y=3}\\
7y=28\\
y=4\\\\
3x-3\cdot4=-3\\
3x-12=-3\\
3x=9\\
x=3\\\\
\boxed{(x,y)=(3,4)}

I will give brainliest to first answer

dangina [55]

No, she is incorrect (in my opinion) i think the answer is :
1/2 m - 4 = 5
4+5 = 9 so
half of 18= 9
so the answer is 18?

The graph of f(x) = 2x + 3 shifts 10 units to the right when it is replaced with the graph of f(x) = 2x − k. What is the value o

Nezavi [6.7K]

Answer:

k=17

Step-by-step explanation:

Given F(x)=2x+3 shifts 10 units when it is replaced with the graph f(x)=2x-k.

The method to solve this kind of questions is find where the graph meets the x axis then add ten units to it .The obtained x coordinate is the point where the second graph meets the x axis.

Now first find where the F(x)=2x+3 meets the x axis by substituting F(x)=0.

$2x+3=0$

$x=-\frac{3}{2}$

Now add 10 to this x coordinate , we get x1= $10-3/2$ = $17/2$

this is x coordinate where the second line meets the x-axis.

The second line is F(x)=2x-k.

now f(x)=0 and x=17/2

On substitution we get $0=2*17/2-k$

k=17
