I think the equation is y=4x+10
Answer:
y=-2x+2
Step-by-step explanation:
Given line is-
x-2y=7
we know,
equation of line perpendicular to ax+by=c is bx-ay=k
So, equation of line perpendicular to x-2y=7
is given by -2x-y=k
Now, the line -2x-y=k passes through (5,-8)
So, we get
-2(5)-(-8)=k
or, -10+8=k
or, -2=k
So, k=-2
Using the k value we get,
Equation of the line is-
-2x-y=-2
multiplying by -1
2x+y=2
or, y=-2x+2
This is the slope intercept form of the line.
Answer:
(1, 2, 3, 4) matches (A, C, B, D)
Step-by-step explanation:
The additive inverse of a term is formed by changing the sign. The additive inverse of the polynomial is formed by changing the sign of every term.
If we call the expressions on the left (top-to-bottom) 1, 2, 3, 4, and those on the right A, B, C, D, then the match-up <em>in this presentation of the question</em> is ...
1 - A
2 - C
3 - B
4 - D
_____
YMMV if the expressions are mixed differently
Answer:
14
Step-by-step explanation:
1 to 9 = +8
9 to 5= -4
5 to 6 = +1
so 6 to next number = +8
= 6 +8
=14
Answer:
1/3
Step-by-step explanation:
Find two corresponding sides that have lengths.
24 in Figure 1 corresponds to 8 in Figure 2.
Divide the length in Figure 2 by the corresponding length in Figure 1.
scale factor = (length in Figure 2)/(corresponding length in Figure 1)
scale factor = 8/24
scale factor = 1/3
