What would you multiply to make the y variable cross out?
-5x + y = -3
3x - 8y = 24
Answers
Answer:
Step-by-step explanation:
-40x + 8y = -24
3x - 8y = 24
-37x = 0
x = 0
0 + y = -3
y = -3
(0, -3)
Answer:
I will show you how to solve for x and y.
Step-by-step explanation:
-5x + y = -3
3x - 8y = 24
You can isolate y in the first equation, and substitute that into the second equation.
so to isolate y in -5x + y = -3, you would add 5x to both sides
this gives you y = 5x - 3
Then substitute this y into the equation below.
3x - 8(5x-3) = 24 (this way, the y variable disappears)
then distribute the 8 into the bracket
3x - 40x + 24 = 24
combine the variables
-37x + 24 = 24
isolate x by moving the constants to one side
-37x = 0
so x = 0
I am not sure if you want the rest, but here it is.
substitute x = 0 into one of the equations.
-5x + y = -3
-5(0) + y = -3
y = -3

Answers
Answer:
slope = -1/4, y-intercept = 50
Step-by-step explanation:
x=0 y=50
x=100 y= 25
y= mx+b
b= 50
25= 100 m +50
100m = - 25
m= -1/4
where m is the slope and b is the y intercept

What is the slope of this line?
Answers
Answer:
A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).
what is the slope of the function below y=5x+8
Answers
Answer:
This function is in y=mx+b form, where m is the slope, and b is the y-intercept.

f(x) = -⁴/₃x + 6Step-by-step explanation:
f(0) = 6 means y-intercept b = 6
So we have:
f(x) = mx + 6 and f(3) = 2
So:
2 = m×3 + 6
3m + 6 = 2
3m = 2 - 6
3m = -4
m = -⁴/₃
Therefore the function:
f(x) = -⁴/₃x + 66 x 16 = 6 x ( _ + 6 )
= (6 x _ ) + ( 6 x _ )
= _ + _
= _ square units

What is rotation?Rotation means the circular movement of an object around a center. It is possible to rotate different shapes by an angle around the center point.
Given:
LMNP is rotated 90° clockwise around the origin.
If we rotate the figure in LMNP about 90 degrees then the coordinates will change into
(x, y) to (y, -x).
As, x= 3, y=4
Hence, the coordinates of M is M’(4,-3).
