Answer:
x = 3 and x = -12
Step-by-step explanation:
To solve an absolute value equation, you create two equations, one where the right side is negated and one where the right side isn't:
| 2x + 9 | = 15 becomes:
2x + 9 = 15 and 2x + 9 = -15
2x = 6 and 2x = -24
x = 3 and x = -12
Why this works is that |-x| and |x| will both be equal to 0. Remember that absolute value is the distance a number is away from 0.
Answer:
x^2-20, -x^2+x, 2^x, x^3+x^2-4, x^4-1, x^5-4x^2+1, x+30 (Least to greatest)
Step-by-step explanation:
Let x take any positive integer, x=2.
#Substitute x with 2 in all the functions to get determine the least to greatest:
Using our calculated values, we can arrange the functions from the least to greatest as:
x^2-20, -x^2+x, 2^x, x^3+x^2-4, x^4-1, x^5-4x^2+1, x+30
Answer:
Angle H = 58 degrees.
Step-by-step explanation:
This is because angle E is congruent to angle H
Answer:
x=93°
Step-by-step explanation:
Angles in a triangle equals 180°
Represent the unknown angle in the triangle with y.
35°+58°+y=180°
93°+y=180°
y=180°-93°
y=87°
Angles on a straight line equals 180°
x=180°-87°
x=93°

Answer:
733
Step-by-step explanation:
18 - √81 + 9 × 3⁴ - ( 3 - 2 + 9 ) ÷ 2
18 - 9 + 9 × 81 - ( 10 ) ÷ 2
(18 - 9) + (9 × 81) (-10 ÷ 2)
9 + 729 - 5
738 - 5
733
