Answer:
C. (4,-7)
Step-by-step explanation:
To answer this question, I just graphed the two equations. Then I found where they intersected.
Answer:
-4, -2, -1, 1
Step-by-step explanation:
If the domain is given we use the equation to determine the range but usually the range would be everything in this equation.
You divide 42 miles by 12 and you get 3.5
So it would take 3 hours and 50 min
Answer:
y= 8x +7
Step-by-step explanation:
<u>slope-intercept form:</u>
y= mx +c, where m is the gradient (or slope) and c is the y-intercept.
Since it is a linear function, the gradient of any 2 points would be equal.

Thus, gradient of the line

Subst. m=8 into the equation:
y= 8x +c
To find the value of c, substitute a pair of coordinates.
When x=0, y= 7,
7= 8(0) +c
c= 7
Thus, the equation of the linear function is y= 8x +7.
13ft you would do 5^2+12^2 with a answer of 169 then you do the square root of that to get 13
