Answer:
(i) k =1
(ii) y-intercept is 7
Step-by-step explanation:
<u>Given line:</u>
<u>Divide all terms by k to get slope-intercept form of the line</u>
<u>Since the gradient (slope) of the line is 2:</u>
<u>The equation is now:</u>
<u>y - intercept is found when x = 0</u>
- x = 0 ⇒
- y = 2*0 + 7
- y = 7
Step-by-step explanation:
the first one is:
2 so not th second one
Any number to the power of a negative integer will be 1 over that number with the absolute value of the power, so it looks like this:
Therefore, you just need to 8² which is 64, and then do 1 over that (1/64) because it's a negative power.
Answer:
45 cm^2
Step-by-step explanation:
The formula you have written in pencil is correct.
Area = B*H
B = 9
H = 5
Area = 5*9
Area = 45 cm^2
Answer:
y=-2x-2.5
Step-by-step explanation:
-2y=x+5
--- --- ---
y= -2x - 2.5
assuming the -2y is negative if not its y=2x+2.5
