We know that
1) <span>Variable x is 7 more than variable y
so
x=y+7
2) </span><span>Variable x is also 1 less than y.
x=y-1
therefore
the answer is
the option
</span><span>x = y + 7
x = y – 1</span>
Answer:
b. y = −0.5x + 5.5
Step-by-step explanation:
Well first we need to find the slope of line CD.
To do that we'll use the following formula,

We'll use the points (1,1) and (3,5)
So y2 is 5 y1 is 1 so 5-1 = 4
3-1 = 2
<u>Slope = 2x</u>
If the slope of line CD is 2x we can cross out choices C and D.
Two lines that are perpendicular to each other have reciprocal slopes,
meaning is the slope of line CD is 2 then its perpendicular lines slope should be -.5.
If the perpendicular line goes through point (-1,6), the y intercept would be, 5.5.

Answer:
B. 12/13
Step-by-step explanation:
The answer choices suggest that you intend the problem to be interpreted as ...
(8/13)/(2/3) . . . . . parentheses are required
= (8/13) × (3/2) = (8·3)/(13·2) = (8·3)/(2·13)
= (8/2) × (3/13) . . . . making use of the associative property
= 4 × 3/13 = 12/13
_____
Your calculator can help with these. You do need to get the parentheses right.
