irakobra [83]

Answer:

x=y

Step-by-step explanation:

-let x be the number of tennis balls and y the number of rackets.

-We divide the number of balls by the number of rackets to find out their ratio of proportionality:

$\frac{x}{y}=\frac{5}{5}=\frac{1}{1}\\\\\\=>x:y$

-Hence, for each one tennis ball, there is a tennis racket.

#This is a direct linear relationship and is modeled as graphed in the attachment:

Whenever you want to write the equation of a parallel line through some point (h, k), you can ...

remove any added constant in the original given equation
replace x with (x-h)
replace y with (y-k)
rearrange the resulting equation to the form required by the problem.

Using this formula here, we get

... 2(y +5) = 3(x -2)

Your answer form requires you solve this for y.

... 2y + 10 = 3x -6 . . . . . eliminate parentheses

... 2y = 3x -16 . . . . . . . . subtract the constant on the left (10)

... y = (3/2)x -8 . . . . . . divide by 2

Which is the answer and how did you solve it?

Its pretty simple

9x-7y = 22
x + 3y = -24

(9x-7y = 22)
-9(x + 3y = -24)
= -9x -27y = 216
+ 9x-7y = 22
= -34y = 238
= / -34 = 238/-34
y = -7

now plug -7 in one of the equation
x + 3(-7) = -24
x -21 = -24
+21. +21
x = -3

so answer is x = -3 and y = -7

Which of the following steps indicates the addition property of equality while solving the equation –1 – 6x = x – 15? Question 4

den301095 [7]

Answer:

B) -1-6 x +15 = x - 15 +15

Step-by-step explanation:

Explanation:-

Given equation is –1 – 6 x = x – 15

By addition property of equality

⇒ - 1 - 6 x + 15 = x - 15 +15

⇒ - 6 x + 14 = x

subtracting 'x' on both sides ,we get

⇒ - 6 x -x +14 =0

⇒ - 7 x +14 =0

⇒ -7 x = - 14

Dividing '-7' on both sides , we get

x = 2

The solution of given equation is x = 2
