Answer:
x = 6
Step-by-step explanation:
The scale factor is
28/8 = 7/2
We take the ratio of the larger side over the smaller side
Using ratios we can find the sides
28 21
----- = ---------
8 x
Using cross products
28x = 21*8
28x =168
Divide each side by 28
28x/28 = 168/28
x =6
Answer:
The given equation cannot be written in slope intercept form
Step-by-step explanation:
we know that
Is the equation of the line in slope intercept form
where
m is the slope
b is the y-intercept
In this problem we have
This is a vertical line (parallel to the y-axis)
The slope is undefined
therefore
The given equation cannot be written in slope intercept form
2(x - 1) > = -12
2x - 2 > = -12
2x > = -12 + 2
2x > = -10
x > = -10/2
x > = -5 or -5 < = x
wrong solution would be B. x less then or equal to -5....because x is greater then or equal to -5
y/x = k
6.4/4 = 1.6
11.2 / 7 =1.6
16/10 = 1.6
20.8 /13 =1.6
This is a direct variation and the constant is 1.6
y=1.6x
I think is
4 x + 2y
256x + 16y
