Answer:
2
Step-by-step explanation:
Given expression:
(√4)⁻⁷ x (√2)⁻⁵
To solve this problem, we are going to use some rules of exponent;
(√4)⁻⁷ x (√2)⁻⁵
4 = 2²
= (√2²)⁻⁷ x (√2)⁻⁵
√x² = x
= ( 2) ⁻⁷ x (2)⁻⁵
= 2⁻⁷ x 2
aˣ x aⁿ = aˣ⁺ⁿ
So;
2⁻⁷ x 2 = 2
= 2
= 2
if you times the 2 factors you will get your answer
To write slope intercept form from a point, you take the 2 and covert it to 2/1, or rise/run form. Then you find the y-intercept. Now listen, this is very complicated. Ready? It's the y-coordinate. 4. Veery complicated.
So y=2/1+4

Answer:
c)
Step-by-step explanation:
Answer:
16 Miles/Hours
Step-by-step explanation:
Average speed is the total distance covered divided by the total time
In that case we have a distance of 4 miles
Time is 15 minutes and in order to convert from minutes to hours we divide by 60 and it becomes 0.25 hours
So 4/0.25 is 16 Miles/Hours
