Answer 1

Answer:

x = -2

y = 9

Step-by-step explanation:

y = -3x + 3

y = 5x + 19

We can put one y as another:

-3x + 3 = 5x + 19

-8x = 16

x = -2

And now let's check using x = -2

y = (-3 * -2) + 3

y = (5 * -2) + 19

y = 6 + 3

y = -10 + 19

y = 9

y = 9

Jim's parents keep a chart on the wall where they mark how much Jim grows each year. When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch. In total, how much did Jim grow in during those two years?

Answers

Answer: 3/4 inch

Step-by-step explanation:

When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch.

His growth during those two years will be:

= 1/4 + 1/2

= 1/4 + 2/4

= 3/4 inch

His growth increased by 3/4 inches.

Answers

Answer:

[tex]x>6[/tex]

Here, [tex]x[/tex] denotes number of books read by Miles in the second half of March

Step-by-step explanation:

Given: Miles read 4 books in the first half of March.

Also, Miles read more than 10 books in a month.

[tex]x[/tex] denotes number of books read by Miles in the second half of March.

To find: inequality that describes the problem.

Solution:

Total number of books read in month of March = Number of books read by Miles in the first half of March + Number of books read by Miles in the second half of March =  [tex]4+x[/tex]

Also, Miles read more than 10 books in a month.

Therefore,

[tex]4+x>10\\x>10-4\\x>6[/tex]

What value of x satisfies the equation below?
[tex]\frac{-2x - 6}{5} = 4[/tex]

Answers

Answer: -13

Step-by-step explanation:

1. Isolate x: move 5 to the otherside

=> -2x-6=4*5 => -2x-6=20

2. Move 6 to the otherside: -2x=20+6 => -2x=26

3. Divide both sides by -2

=> x=26/-2 => x=-13

Answers

Answer:

slope = -10/7

Step-by-step explanation:

co-ordinates = (6,-2) (5,-4)

slope = (y² - y¹) / (x² - x¹)

slope = (-4 - 6) / (5 - (-2))

slope = (-10) / (5+2)

slope = (-10) / 7

In the diagram, △ABC∼△CDE. Write an equation for line k

Answers

Answer:

Step-by-step explanation:

Line AB is parallel to line CD (k) so they have the same slope.

slope=m=(y2-y1)/(x2-x1)

m=(6-0)/(4-0)

m=6/4=1.5

y=mx+b, we know m=1.5 so

y=1.5x+b, and we know it passes through point (4,0) so we can solve for b

0=1.5(4)+b

0=6+b

b=-6 so line k is

y=1.5x-6
