Answer:
$ 12.09
Step-by-step explanation:
formula Y = KX
Where; y = $ 24.18
x = 2 books
k = constant of proportionality
Step 1. Do the equation based on the formula
Y = kx
$24.18 = k2
Step 2. Divide by 2
$24.18/2 = k2/2
k = $12.09 (answer)
Given that solution for some equation is x=6
Now they want to change x=6 into x=9.
Notice that all equations contans equal sign (=) because both side values are always same.
So if by any chance you want to change value of one side then you must change value on other side too
like we see that 6 changed to 9 by adding 3 on right side then we must add 3 on the left side too
so we get:
x=6
x+3=6+3
x+3=9
Now question says that the left side of the equation stays the same. That is possible only if we move +3 to the right side from the left side so we can write;
x=9-3
Answer:
2 x 7 x 3²
Step-by-step explanation:
When finding primes, you use the method I attatched as a picture. Start with the large number at the top, slowly dividing it by factors of it.
The picture shows that the primes 126 is a product of is:
2, 7, 3, 3
Or:
2 x 7 x 3 x 3
This can be simplified into:
2 x 7 x 3²
Hope this helps!
A. NOT
(-5, 2) → x = -5, y = 2
y ≤ x - 5 → 2 ≤ -5 - 5 → 2 ≤ -10 FALSE
B. YES
(5, -2) → x = 5, y = -2
y ≤ x - 5 → -2 ≤ 5 - 5 → -2 ≤ 0 TRUE
y ≥ -x - 4 → -2 ≥ -5 - 4 → -2 ≥ -9 TRUE
C. NOT
(-5, -2) → x = -5, y = -2
y ≤ x - 5 → -2 ≤ -5 - 5 → -2 ≤ -10 FALSE
D. NOT
(5, 2) → x = 5, y = 2
y ≤ x - 5 → 2 ≤ 5 - 5 → 2 ≤ 0 FALSE
