Answer:
PQ is perpendicular to RS
that is to mean:
PQ⊥RS
Step-by-step explanation:
Answer:
<h2>y = 4x + 4</h2>
Step-by-step explanation:
The slope-intercept form:
m - slope
b - y-intercept
Parallel lines have the same slope.
We have y = 4x + 2 → m = 4.
The slope of parallel line is m = 4 and the y-intercept b = 4.
Therefore we have the equation of a line:
Y = -4x

Answer:(7/8 - 4/5)^2 = 9
1600
= 0.005625
Step-by-step explanation:
Subtract: 7
8
- 4
5
= 7 · 5
8 · 5
- 4 · 8
5 · 8
= 35
40
- 32
40
= 35 - 32
40
= 3
40
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
40
) ^ 2 = 32
402
= 9
1600
In words - three fortieths squared = nine one-thousand six-hundredths.
