Y=24x+48
24 per hour (x) plus the 48 she already made would equal a total (y).
Answer:
The two numbers are -5 and -4
Explanation:
Assume that the first number is x and that the second number is x+1.
We know that the sum of their squares is 41. This means that:
x² + (x+1)² = 41
We will expand the brackets and factorize to get the value of x as follows:
x² + (x+1)² = 41
x² + x² + 2x + 1 = 41
2x² + 2x + 1 - 41 = 0
2x² + 2x - 40 = 0
We can divide all terms by 2 to simplify the equation:
x² + x - 20 = 0 ..........> equation required in part II
Now, we can factorize this equation to get the values of x:
x² + x - 20 = 0
(x-4)(x+5) = 0
either x = 4 .........> rejected because we know that x should be negative
or x = -5 ...........> accepted
Based on the above calculations, the two numbers are -5 and -4
Hope this helps :)
Y = kx, where k is the constant of proportionality.
We need to find k as our first step.
35 = k140
35/140 = k
1/4 = k
We can now find y when x = 70.
y = kx
y = (1/4)(70)
y = 70/4
This fraction can be simplified or reduced more.
The number 2 is the GCF of 70 and 4.
70 ÷ 2 = 35
4 ÷ 2 = 2
Answer:
y = 35/2
Answer:
f(13)=2x-1, x=7
Step-by-step explanation:
7*2=14, 14-1=13
vise versa
f(13)=2(7)-1
I can only help with d... the answer is 38.
