We can use ratios, in other words, if one part of the photo is changed x times, how many times does the other part change?
We can set up the proportion as :
width 1 : length 1 = width 2 : length 2
20 : 30 = 5 : x
We do inverse multiplication, or multiply the outer with outer and inner with inner (W1 * L2 and L1 * W2)
20*x = 30*5
20x = 150
Divide all by 10
2x = 15
Divide all by 2 to isolate x
x = 15/2
x = 7.5cm
The THIRD statement is not true.
$2000 (spends a month)
The 5% of $2000 is only $100 for food.
The first statement is true "The household spend $260 per month on the car".
13 % of $2000 = $260
The second statement is true "The household spend $600 per month for rent".
30% of $2000 = $600
The fourth statement is also true "The household spend $200 in savings each month"
10% of $2000 = $200
Answer:
Step-by-step explanation:
Compare any two points on same horizontal line.
<u>The easy one is:</u>
<u>Since g(x) = f(kx), substitute the x- coordinates to find the value of k:</u>
- - 1 = k*(-3)
- k = - 1/ - 3
- k = 1/3
Correct choice is B
Answer:
no solutions
Step-by-step explanation:
4x - 8 = 4x
Subtract 4x from each side
4x-4x - 8 = 4x-4x
-8 = 0
This is never true, so there are no solutions
