45% of 40 is 0.45×40=18 girls
if x girls join then 56% of 40+x is 0.56(40+x)=18+x
22.4+0.56x=18+x
put together like terms
4.4=0.44x
<span>x=10 girls joined</span>
Answer:
Because each word describes something completely different compared to the others. You normally do not hear of a hot winter or a wet desert.
Answer:
x-intercepts: (-4,0) and (-2,0) y-intercepts: (0,-2)
Step-by-step explanation:
<u>x-intercept</u>:
y = |x+1| - 3
0 = |x+1| - 3
3 = |x+1|
The numbers -4 and 2 are the x-intercepts because if you add -4 and 1, you get the absolute value of -3, which is 3. If you add 2 and 1, you get the absolute value of 3, which is 3.
<u>y-intercept</u>:
y = |x+1| - 3
y = |0+1| - 3
y = |1| - 3
y = 1 - 3
y = -2
Answer:
f(x) = |x| - 7
Step-by-step explanation:
The given equation is g(x) = |x|......... (1)
The vertical translation by 7 units down will not change the value of x, the only change will be in the value of g(x).
The vertical translation by 7 units down will change the value of g(x) by [g(x) + 7] in the left-hand side of the equation (1).
Therefore, the equation will become g(x) + 7 = |x|
⇒ g(x) = |x| - 7.
Otherwise we can represent the function as some other name say f(x).
So, f(x) = |x| - 7. (Answer)
