Answer:
It is the same speed everyday
Step-by-step explanation:
It is a constant speed
To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5
then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5
Answer:
y = (3/4)x - 6
Step-by-step explanation:
if line is parallel to -3x + 4y = 4, that means that they both have the same slope
Slope of that second line is 3/4.
now time to find the y-intercept
0 = 3/4*8 + b
therefore, b = -(3/4)*8 = -3*2 = -6
Therefore, equation of line is y = (3/4)x - 6
Answer: The correct answer is 3
Step-by-step explanation:
4³ = 64
The way to check your work is to multiply 4 x 4 x 4:
16 x 4 = 64
Answer:
25
Step-by-step explanation:
Expression: <em>(2⁸ ⋅ 5⁻⁵ ⋅ 19⁰)⁻² ⋅ (5⁻²/2³)⁴ ⋅ 2²⁸</em>
Inner-most powers: 2⁻¹⁶ • 5¹⁰ • 1 • 5⁻⁸/2¹² • 2²⁸
Combine like terms: 2¹² • 5²/2¹²
Cancel out: 5²
Solve: 25
