Answer:

x=4

Step-by-step explanation:

7x - 9 = 19

add 9 to both sides

7x = 28

divide by 7

Answer:

x=4

Step-by-step explanation:

First, you take the equation and add 9 to both sides (7x-9+9=19+9) which will cancel out the 9 on the left side, and add onto the 19 which would be 28.

Next, you simplify the answer of that to get 7x=28

After you divide 7 from both sides (\frac{7x}{7}=\frac{28}{7})

Finally, after solving that division problem you will get the answer of the equation which is x=4

Find the equation of the line
amm1812

Answer:

y = 2x - 7

Step-by-step explanation:

The question is asking for slope-intercept form, y = mx + a.

Given:

(1, -5) and (9, 11)

Find the slope (m) between the two points:

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

x1 = 1

x2 = 9

y1 = -5

y2 = 11

m = ( 11 - (-5) )/(9 - 1)

= 16/8

m = 2

y = 2x + a

Use one of the two points to find a (I will use (1, -5)):

-5 = 2(1) + a

-5 = 2 + a

-7 = a

a = -7

y = 2x + (-7)

y = 2x - 7

emmainna [20.7K]

Answer:

1 adult cat

Step-by-step explanation:

<u>Thursday:</u>

The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.

Number of adult cats = 4x

Number of kitten cats = 3x

There were 12 kittens, then

3x=12\\ \\x=\dfrac{12}{3}\\ \\x=4\\ \\4x=4\cdot 4=16

There were 16 adult cats

<u>Tuesday:</u>

17 adult cats were at the pet care center.

<u>Difference:</u>

17-16=1 adult cat
