Answer:

Rise/Run = Slope = 3/4 (rises 3 units and goes 4 units to the right)

y-intercept (where the line crosses the y axis) = (0,0)

function (basically the equation) = f(x) = 3/4x

Which expression is equivalent to the following expression? 10x + 3(8 - 7x)

Paladinen [302]

It is -11x + 24 because you multiply the numbers in the parentheses by 3 then collect like terms 10x +24 - 21x then you do 10x minus 24x and you get -11x+24

Please help! :) Need answer fast!

Vlada [557]

Answer:

x = 3

y = 2

Step-by-step explanation:

When 2 triangles are congruent, they will have exact same 3 sides length and exact same 3 angles measure.

So we can say:

-2x + 6y = 6

and

-7x + 8y = -5

Let's multiply first equation by 7 and 2nd equation by -2, to get:

7 [-2x + 6y = 6] = -14x +42y = 42

and

-2 [-7x + 8y = -5] = 14x - 16y = 10

Now adding these 2 new equations and solving for y:

-14x +42y = 42

14x - 16y = 10

----------------------

26y = 52

y = 52/26

y = 2

Now we put y = 2 into 1st equation (or any other) and solve for x:

-2x + 6y = 6

-2x + 6(2) = 6

-2x + 12 = 6

6 = 2x

x = 6/2

x = 3

If 97 of 200 is 100% then how much of 200 is 112%

pickupchik [31]

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 112 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 112 is 100%, so we can write it down as 112=100%.
4. We know, that x is 200% of the output value, so we can write it down as x=200%.
5. Now we have two simple equations:
1) 112=100%
2) x=200%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
112/x=100%/200%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 200% of 112

112/x=100/200
(112/x)*x=(100/200)*x - we multiply both sides of the equation by x
112=0.5*x - we divide both sides of the equation by (0.5) to get x
112/0.5=x
224=x
x=224

now we have:
200% of 112=224

●I tried my best I was never good with percentages my least favorite.... Please let me know if you got it wrong. If you do I'm sorry.

Which of the following statements about unit rates is NOT true?

atroni [7]

Answer:

A) A unit rate relates a quantity to 1 : TRUE

B) unit rates can be used to compare two rates : TRUE

C) any rate is equivalent to its unit rate

. FALSE

D) a unit rate always relates quantities with the same units. FALSE

Step-by-step explanation:

The ratio that which is used to compare quantities of different kinds is known as the rate of that quantity.

A unit rate is the ratio.

Number of units of the first type of quantity : Number of units of the second type of quantity.

Now,

A) a unit rate relates a quantity to 1.

TRUE, as a UNIT is equivalent to one.

Hence, unit rate unit rate relates a quantity to 1.

B) unit rates can be used to compare two rates

TRUE, unit rate compares two rates.

C) any rate is equivalent to its unit rate

FALSE, only the rate of one single unit is equivalent to its Unit Rate.

D) a unit rate always relates quantities with the same units

FALSE, rate compares the two terms which are in different units.

the cost of a renting a car is $55/wk plus $0.15/ mi traveled during that week . an equation to represent the cost would be y =5

Morgarella [4.7K]

The maximum number of miles you could drive would be 300.
Multiply 0.15 by 300 and that adds up to $45. 45 + 55 = $100
An equation to explain this would be
y = 55 + 0.15x
y represents your $100 budget, 55 is the initial rental fee, and if you plug 300 in for x that solves your equation.
