Answer:

3x-5 y=2

is graphed below.

Answer:

m = 10

Step-by-step explanation:

multiply 0.2 to both sides.

Use the oposite operation of division which is multiplication, you always multiply the denominator

Answer:

M = 10

Step-by-step explanation:

Since we’re solving for M

We multiply both sides by 0.2

50(0.2) = 10

Answer:

A: M= 100 - w=20 = M-0

 ( if he has 100 dollars n he buys a 5 dollar coffee every week then he will have 0 dollars left over in 20 weeks )

B.  6 weeks

Answer:

A. m = 100 - 5w

B. 17 weeks

Step-by-step explanation:

Answer:

A

Hope it helps and i don't know how to explain

Answer:

car b has a steeper slope tho... so it's car b

Answer:

Expand the following expression

(3x+1)(x-4) = 3x^2-12x+x-4

middle term = -11x

Answer:

391.5 in²

Step-by-step explanation:

SA = 2(9)(10) + 9(10) + 13.5(9)

SA = 180 + 90 + 121.5

SA = 391.5

Answer:

Step-by-step explanation:

y is always (1/3) of x.

Thus, if x = 0, y = 0; if x = 1, y = (1/3)(1) = 1/3, and so on.  The corresponding ordered pairs are (0, 0), (1, 1/3), (-2, -2/3)

Answer:

a. -24w^6/y^7z^3

Step-by-step explanation:

i hope this helps :)

Answer:

B, y=2x

Step-by-step explanation:

Because the x is doubling Every time you go up the line

Answer: The answer is 81

Step-by-step explanation:

because 9x9=81 so u don't multiply the whole square like this

9x9x9x9=36 thats wrong and that was my mistake but yeah it would be 81.

Answer:

-1/7

Step-by-step explanation:

11x-1 = 1+25x

x= -1/7

Answer:

d = 9/10

Step-by-step explanation:

Hi,

d divided by 5/6 = 3/4

You can't divide fractions, instead, you flip the fraction and multiply. So, in this case, you would flip 5/6 to get 6/5 and multiply it by 3/4 to get d.

d ÷ 5/6 = 3/4

Multiply both sides by 6/5 (remember to flip)

d = 3/4 x 6/5

(when multiplying fractions, you can multiply straight across)

d = 18/20

(simplify - both numbers can be divided by 2)

d = 9/10

Hope this helps :)

Answer:

d = 5/8

Step-by-step explanation:

Mulitply by the reciprocal

= d x 6/5 = 3/4

Reorder the terms

=6/5d = 3/4

Multiply both sides

Solution

d = 5/8

Alternate form

d = 0.625

Step-by-step explanation:

3 bags = 5.55, divide that and youll get 1.85 then take 1.85 times 2 for two bags of chips and you will end up with B - 3.70

Answer:

35 / 4 = 8.75

35 - 8.75 = 26.25

I hope you a great life. Till we meet again, Farewell!

what you need to do is plug in the X-imput into the exponential slot that has the tiny X.

your answer is "C"

thanks! :)

Answer:

$24750

Step-by-step explanation:

Given data

Principal= $45000

Time=5 years

Rate= 11%

Let us apply the simple interest expression

SI= PRT/100

substitute

SI= 45000*11*5/100

SI= 2475000/100

SI= $24750

Hence, Craig would have paid $24750

Answer:

B

Step-by-step explanation:

.99n + 19.99

2 songs

.99(2) + 19.99

1.98 + 19.99 = 21.97

Answer:

Step-by-step explanation:

You may invent a value for x, substitute that value into the given equation and thereby calculate y:

If 7x - 4y = -5 and x = 0, then -4y = -5 and y = 5/4.  The corresponding ordered pair is (0, 5/4).  Other x values may be chosen at random and the same operations performed so as to find other possible ordered pairs corresponding to 7x -4y = 5.

Answer:

second one

Step-by-step explanation:

Answer:

x = 7y - 16

Step-by-step explanation:

First, isolate x by adding 14y to both sides:

2x - 14y = -32

2x = 14y - 32

Now, divide each side by 2:

x = 7y - 16

So, x = 7y - 16

Answer:

x=-16+7y

Step-by-step explanation:

Answer:

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:

A line is increasing, and goes upwards from left to right when m > 0

A line is decreasing, and goes downwards from left to right when m < 0

A line has a constant slope, and is horizontal when m = 0

A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.

Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:

m =

y2 - y1

x2 - x1

Answer:

no the solution would be (-2, -8)

Step-by-step explanation:

i graphed both of the equations and found the solution <33

Answer:

(-2,-8) is correct

Step-by-step explanation:

4x = y

5x +2 = y

4x = 5x +2

-2 = x

y = 5×-2 + 2

=-8
