Mathematics
1 answer:
abruzzese [7]3 years ago
4 0

Answer:

25 and 35

Step-by-step explanation:

Let the numbers be 5x and 7x

(5x+5)/(7x+5)=3/4

4(5x+5)=3(7x+5)

20x+20=21x +15

20-15=21x-20x

5=x

So,the numbers will be

5x=5*5 =25

7x=7*5=35

SOMEONE PLEASE HELP ME QUESTION 5 2 PARTS IN THE PICTURE!!!!!
Phantasy [73]

Answer:

  x ≥ 6; see below for a graph

Step-by-step explanation:

First inequality

  7x -6 > 8

  7x > 14 . . . . . . add 6

  x > 2 . . . . . . . .divide by 7

Second inequality

  3x+4 ≥ 22

  3x ≥ 18 . . . . . . subtract 4

  x ≥ 6 . . . . . . . . divide by 3

The values of x that will satisfy both inequalities are x ≥ 6. (All of those values are > 2.)

The solution to the inequalities is x ≥ 6.

__

Your graph will have a solid dot at x=6, indicating 6 is part of the solution set. It will be shaded to the right, with an arrow at the right end.

Which equation is the slope-intercept form of the line that passes through (6, –11) and is parallel to the graph of y = –2/3x +
IRINA_888 [86]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

From the question the original line is

y = - ⅔x + 12

Comparing with the general equation above

Slope = -⅔

Since the lines are parallel their slope are also the same

Slope of parallel line = - ⅔

The equation of the line using point

(6, –11) and slope - ⅔ is

y + 11 =  -  \frac{2}{3} (x - 6) \\ y + 11 =  -  \frac{2}{3} x + 4 \\ y =  -  \frac{2}{3} x + 4  - 11

We have the final answer as

y =  -  \frac{2}{ 3 } x  - 7 \\

Hope this helps you
