Answer:
32?
Step-by-step explanation:
16×2=32
not sure what the numbers after that means but
x8=128
x16=256
x4=64
Answer:
yes
Step-by-step explanation:
To determine if the point lies on the line substitute the coordinates into the left side of the equation and if equal to the right side then the point lies on the line
- 3 + (4 × 4) = - 3 + 16 = 13 = right side
Hence (- 3, 4) lies on the line x + 4y = 13
You need to include the image of the question it doesn’t make sense if
We are given two points: (4, -8) and (8, 5)
General equation of a line: y = mx + c
First find m (the gradient). There is a formula for this: (change in y)/(change in x) = gradient
(5 - -8) / (8 - 4) = (13) / (4) = 3.25 = m
y = 3.25x + c
Now we need to find c (the y-intercept; the value of y when x=0).
Substitute in any one of the coordinates - let's use (8, 5)
(5) = 3.25(8) + c
(5) = 26 + c
c = -21
The equation of the line: y = 3.25x - 21
I think that this answer is correct - sorry if it seems rushed.
Hope this answer helps :)
Answer:
v = -38
Step-by-step explanation:
v/2 + 15 = -4
Subtract 15 from each side
v/2 + 15-15 = -4-15
v/2 = -19
Multiply by 2
v/2 *2 = -19*2
v = -38
