Step-by-step explanation:
Given
Cost of Textbooks ---- Frequency
$25 up to $35 ----- 2
$35 up to $45 ------- 5
$45 up to $55 ------- 7
$55 up to $65 ------ 20
$65 up to $75 ---- -- 16
Required
Determine the relative class frequency for the $25 up to $35 class
First, we need to get the total frequency
Next, is to write out the frequency of $25 up to $35 class
Divide this frequency by the total frequency; This gives the relative frequency
Hence;
Option D answers the question
Let the solutions be a and b.
a = -2; b = -10
a + b = -2 + (-10) = -12
ab = (-2)(-10) = 20
(x - a)(x - b) = 0
(x - (-2))(x - (-10)) = 0
(x + 2)(x + 10) = 0
x^2 + 10x + 2x + 20 = 0
x^2 + 12x + 20 = 0
-h = 12
h = -12
4k = 20
k = 5
Answer:
392 lei găsiți rata unitară de 24 și 168 împărțind 168 la 24 pentru a obține 7, apoi înmulțiți 56 cu 7 pentru a obține răspunsul dvs., care este 392
Step-by-step explanation:
Translated- Question: 24 m of canvas costs 168 lei. How much does 56 m of canvas of the same kind cost? Please give me the crown!!!
Answer: 392 lei you find the unit rate of 24 and 168 by dividing 168 by 24 to get 7 then you multiply 56 by 7 to get your answer which is 392.

Answer:
Parallel
Step-by-step explanation:
Parallel lines have the same slope but different y-intercepts. If you multiply the top equation by 2, you get:
2(12x + 4y = 16)
24x + 8y = 32
This shows that both lines have the same slope, but then you find the y-intercepts, they are different:
1st equation y-int = 4
2nd equation y-int = 9/2 or 4.5
