4- Зу = 31
what’s the answer ?

Answer:

the water is leaking at a rate of 3/4 a gallon per hour

Step-by-step explanation:

we know this because rate of change is change in y over change in x and as y goes up 3 x goes up 4 so the rate of change is 3/4

Answer:

8544

Answer:

r (-2)= -(-2)-7

=+2-7=-5

Answer:

w = 8

Step-by-step explanation:

–9 = –3(w − 5)

-3(w - 5) = -9

w - 5 = 3

w = 5 + 3

w = 8

Answer:

hello! have a good day

w = 8

Answer:

An altitude of a triangle is a segment from a vertex of the triangle, perpendicular to the side opposite that vertex of the triangle.

Step-by-step explanation:

Answer:

A and B, but I’m gonna explain it the best I can too.

Step-by-step explanation:

5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.

Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.

This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression

they have to add up completely the same.

the common RATIO is 4

Answer:

The two lines 'm' and 'n' are parallel

Step-by-step explanation:

Explanation

Given that the line 'm' points (3,15) and (10,9)

The slope of the line 'm'

                = [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} } = \frac{9-15}{10-3} = \frac{-6}{7}[/tex]

Given that the line 'n' points (2,9) and (9,3)

The slope of the line 'n'

             = [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} } = \frac{3-9}{9-2} = \frac{-6}{7}[/tex]

The slope of line 'm' = The slope of  line 'n'

Both slopes of the lines are equal

∴ The two lines are parallel

Answer:

7

Step-by-step explanation:

2+5=7

Step-by-step explanation:

hence , the required number is 12 / 5. therefore, 12 / 5 should be subtracted from - 3 / 5 to get - 3.

Answer:

A

Step-by-step explanation:

distributive property

Answer:

I would say A

Step-by-step explanation:

it's A since 5y times 2 which is 10y and 3 time 2 is 6 and its still equivalent to (5y - 3) times 2 so it's 10y - 6

Answer:

the numerator is: 22

the denominator is : 30

___________________

the simplified numerator is: 11

the simplified denominator is: 15

Step-by-step explanation:

Answer: 22/30 reduced is 11/15

Step-by-step explanation: Half 22/30 to get 11/15, (so 22/2=11 and 30/2=15) Your numerator would be 11, and your denominator is 15.

Hope this helps!

Answer:

See below.

Step-by-step explanation:

x + 2 = x + 2 ⇒ Infinitely Many Solutions

3x + 1 = 3x - 10 ⇒ 1 ≠ -10 ⇒ No solutions

x + 4 = 2x + 4 ⇒ 4 = x + 4 ⇒ 0 = x ⇒ One solution

Answer:

m=-3

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

Slope = Rise/Run

We can find the amount between 7 and -5 as 12, and -2 and 2 as 4.

Then we can do rise/run and 12/4

Which would divide into 3.

ANd because we can see the x increases as the y decreases, we can find that it's a negative slope.

-3

Answer:

slope= -3

y-intercept= 6

Step-by-step explanation:

1. Approach

To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.

2.Solve for the slope

The formula to find the slope of a line is;

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where (m) is the variable used to represent the slope.

Use the first two given points, and solve;

(1, 3), (2, 0)

Substitute in,

[tex]\frac{(0)-(3)}{(2)-(1)}[/tex]

Simplify;

[tex]\frac{-3}{1}\\\\=-3[/tex]

3. Put equation into slope-intercept form

The equation of a line in slope-intercept form is;

[tex]y = mx + b[/tex]

Where (m) is the slope, and (b) is the y-intercept.

Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).

[tex]y=-3x+b[/tex]

Substitute in point (3, -3)

[tex]-3=-3(3)+b\\-3 = -9 + b\\6 = b[/tex]

Answer:

your question is unclear

Step-by-step explanation:

x+2y=4

-x -x

2y=4-x

divide by 2 to get y by it's self

y=2-(1/2x)

x+2y=4

-2y -2y

x=4-2y

i don't know if u want me to help u with the second one but i did it the first one

Answer:

x = 7, y = 2

Step-by-step explanation:

x= 4y -1

since x is by itself 4y-1 will substitute for x in the other equation x+2y=11

it will become 4y-1+2y=11

+1 +1

add one to both sides since is doesn't have a variable.

it will become 4y+2y= 12 now add 4y+2y

becomes 6y=12

_ _

6 6

divide by 6 on each side and you get y=2.

now x=4(2)-1 you will substitute y into the first equation.

x=8-1 subtract 8 from 1 to get 7.

x=7

y=2
