Step-by-step answer:
A line with slope (or gradient) m, passing through a point (x0,y0) can be represented by the equation:
(y-y0) = m(x-x0) ......................(1)
Here,
(x0,y0) = (1,7), and
slope/gradient = -2
Substitute values into (1) above gives
(y-7)=2(x-1)
Expand and simplify
y-7 = 2x-2
y =2x -2 + 7
y=2x+5
is the final answer.
Answer:
3.75 hours
Step-by-step explanation:
Given data
DIstance driven from Gary, Indiana to Indianapolis= 160 mile
Time taken= 2 1/2 hours or 2.5 hours
Speed= distance/time
Speed= 160/2.5
Speed= 64 miles per hours
We want to find the time it will take to drive 240 miles at the same speed
Time= distance/speed
Time= 240/64
Time= 3.75 hours
Answer:
tan (A) = 1
Step-by-step explanation:
When sine and cosine are equal to each other, they have the same value. We know that tan (A) = sin (A) / cos (A). If sin (A) and cos (A) are the same, and any number divided by itself equals 1, the final answer must be tan (A) = 1.
D is equal to 7 because 7x5=35-5=30
