Answer:
12 pairs of socks
Step-by-step explanation:
74-38=36
36÷3=12
You subtract 38 from 74 to find out how much money he has left after buying the sweatshirt. You then divide that number by 3 to figure out how many pairs of socks he can buy with the money he has left.
Answer:
y = 4x
Step-by-step explanation:
A direct variation has NO number added or subtracted like the b in
y = mx + b
The m is the slope which was given.
y = 4x
If P is a point in the x axis therefore this means that
the y must be zero. Hence the coordinate of p is (x, 0).
We can use the distance formula to solve for the value of
x:
d^2 = (x – x1)^2 + (y – y1)^2
13^2 = (x + 3)^2 + (0 – 5)^2
169 = (x + 3)^2 + 25
(x + 3)^2 = 144
x + 3 = ± 12
x = -15, 9
Hence P has two possible coordinates:
<span>(-15, 0) and (9, 0)</span>
Answer:
(f-g)(x) = x^2 - 3x + 2
Step-by-step explanation:
If f(x) = x^2+ 1 and g(x) = 3x-1
Then (f-g)(x) = (x^2+ 1 )(-(3x-1)
(f-g)(x) = x^2 + 1 - 3x + 1
(f-g)(x) = x^2 - 3x + 2
