4) 4x + 3y = 56<br> 2x + y = 24<br> Solve using elimination please show work
lesya [120]

Answer:

x = 8     y = 8

Step-by-step explanation:

Multiply 2nd equation by -3 to get -6x - 3y = -72

Now  4x + 3y = 56

         <u>-6x - 3y = -72</u>

         -2x      =  -16

            x = 8

Substitute x = 8 into the 2nd equation

2(8) + y = 24

16 + y = 24

y = 8

Check:  Substitute the values into the 1st equation

4(8) + 3(8) = 32 + 24 = 56  So we have the correct values for x and y

Can someone help me wit this problem it is 20 points and i need to work on it for school and i Am very confused. Please help
LUCKY_DIMON [66]
So the slope of the first line is 4/3. If this line is perpendicular, then you have to flip it and switch the sign (flip it n switch it (how I remember it)). So the slope of the new line is -3/4.
Then you have to plug in the point you're given and the new slope. Use y=mx+b format.
-1=-3/4*-4+b
Then solve for b.
-3/4*-4 is 3.
-1=3+b
Subtract 3 from each side.
-4=b.
So now you have the y-intercept and slope. All you have to do is plug it in.
y=-3/4x + -4 or y=-3/4 - 4
There's your answer!
