Answer:
Step-by-step explanation:
hello :
7x-6 = 3x+14
7x-3x =14+6
4x=20
x=20/4
<h2>
x=5</h2>
Part A: variables: x, y coefficients: 15, 100
Part B: 2 terms: 15x, 100y because they are separated by a + sign
Part C: 15x shows the total earned from her allowance
Answer:
12
Step-by-step explanation:
Through 12 years he would have painted 72 paintings and since he hasn't sold two of them he has only sold 70.
Answer:
Step-by-step explanation:
The inverse is found by interchanging the x and y values and solve the result for y.
I will use y for f(x)
y = 4x^2
Inverse
x = 4y^2 Divide by 4
x/4 = 4y^2 /4
x/4 = y^2 Take the square root of both sides.
sqrt(x/4) = sqrt(y^2)
y = sqrt(x/4)
g(x) = sqrt(x/4) If you have a very fussy teacher, the inverse function could be written as
g(x) = +/- sqrt(x)/2
I expect that if the question is computer marked, I would try g(x) = sqrt(x)/2 first.
Answer:
6
Step-by-step explanation:
You want ...
4x +24 = 8x
24 = 4x . . . . . . . . subtract 4x
6 = x . . . . . . . . . . .divide by 4
When x=6, the slats are parallel.
