Answer:
y= -5/2 + 17
Step-by-step explanation:
y=mx+b
-8=-5/2(10)+b
-8=-25+b
17=b
y = -5/2x + 17
5a(b-c)=d. Here, we are trying to isolate the variable b.
Divide both sides by 5a: b-c=d/(5a)
Add c to both sides: b=
Answer:(7/8 - 4/5)^2 = 9

Step-by-step explanation:
Subtract: 7

= 7 · 5
8 · 5
- 4 · 8
5 · 8
= 35

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - seven eighths minus four fifths = three fortieths.
Exponentiation: the result of step No. 1 ^ 2 = (3

In words - three fortieths squared = nine one-thousand six-hundredths.
