Answer:

Non-proportional.

Step-by-step explanation:

Membership fee of Rub-a-Dub Carwash = $100

Cost of every car wash in his visit = $12

Total payment Devon has to make in x car washes = $(12x + 100)

Graph of the relation between "total payment" and "number of visits", doesn't pass through origin. (having y-intercept = 100)

While for proportional relationship graph should pass through origin.

Therefore, this relationship is non-proportional.

3/4(x + 3) = 9<br><br><br> How do I solve this
Sonbull [250]

Answer:

x = 10

Step-by-step explanation:

so first distribute the 3/4 to everything on the inside

3/4x + 1 1/2 = 9

now subtract 1 1/2 on both sides

3/4x = 7 1/2

Now divide both sides by 3/4

x = 7 1/2 divided by 3/4

x = 15/2 divided by 3/4

x = 15/2 times 4/3

x = 5/1 times 2/1

x = 10

Shanice's car is traveling 10 miles per hour slower than twice the speed of Brandon's car. She covers 93 miles in 1 hour 30 minu
joja [24]

Shanice's rate: 93 / 1.5 = 62 miles per hour

she is 10 miles slower than twice the speed of Brandon

62 +10 = 72

72/2 = 36

 Brandon is driving 36 miles per hour

Graphing linear equations
ella [17]

Answer:

To ensure uniformity on an exam

Or

To test whether you can distinguish between the two formats

Step-by-step explanation:

Standard form is when a straight line equation is rearranged in the form:

ax + by = c

Therefore y=2x+4 in standard form is

2x - y =  - 4

The slope-intercept form is when a a straight line equation is written in the form:

y =  mx + c

where m is the slope and c is the y-intercept.

The given equation is

y =  -  \frac{1}{2} x  - 5

This is already in slope-intercept form:

The standard form and slope-intercept forms are just formats.

Your instructor may restrict you to leave your answer in one of these formats maybe for uniformity on a test.

You may also decide to rewrite an equation in slope-intercept form, so that you can easily identify the slope and y-intercept easily for graphing purpose.

I need the answer quickly please
Hoochie [10]

Answer:

c²=√181=13.45, or 13.5

Step-by-step explanation:

The pythagorean theorem is a²+b²=c²

Given this, we will plug in our numbers like this: 9²+10²=c²

9²+10²=181, but we have to find the square root of that.

c²=√181=13.45, or 13.5

I hope this helps!! :)
