If the first number is increased by 7 and the second number is reduced by 6 times, the sum of these numbers is 29.

Marta_Voda [28]

Answer:

First number = 20

Second number = 12

Explanation:

Let the 1st number be x

Let the 2nd number be y

=====================

Condition 1

$\sf \rightarrow x + 7 + \dfrac{y}{6} = 29$

$\rightarrow \sf x=-\dfrac{y}{6}+22$

=====================

Condition 2

$\rightarrow \sf 2y - (x - 5) = 9$

$\rightarrow \sf x = 2y -4$

=====================

Substitute equations

$\rightarrow \sf -\dfrac{y}{6}+22 = 2y-4$

$\rightarrow \sf y=12$

=====================

Find value of 1st number

$\rightarrow \sf x = 2y - 4$

$\sf \rightarrow x = 2(12) - 4$

$\rightarrow \sf x = 20$

HELP PLEASE ASAP IM SO CONFUSED!!!!!!!!

liubo4ka [24]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

We have the points (-4, -6) and (2, 6). Substitute:

$m=\dfrac{6-(-6)}{2-(-4)}=\dfrac{12}{6}=2\\\\y=2x+b$

Put the coordinates of the point (2, 6) to the equation of a line:

$6=2(2)+b\\\\6=4+b\qquad|-4\\\\2=b\to b=2$

<h3>Answer: y = 2x + 2</h3>
