Ok, so first we must understand what the slope of a line actually is. The slope, or gradient, is the value by which y increases (or decreases, if this is negative) for each increase of one unit in the x-value. So basically what you should think about for this question is, as x increases, does y decrease, increase or stay the same?

From the graph, we can see that as the value of x gets larger, the value of y also increases, therefor the slope is positive.

For the other answers:

If the slope were negative, we would see that the y-values would get smaller as x would get bigger.

If the slope was zero, you would see a horizontal line; this means that there is no change in the y-value as x-increases.

If the slope was undefined, you would see a vertical line; this is an extreme case where you cannot say how much y increases by as the line continues till infinity, therefor we say that it is undefined.

An integer has to be either even or odd

Even numbers are numbers divisible by 2, while odd numbers are not

Let us represent the 2 even numbers like this

ax+1

bx+1

When you add the two numbers together, you get

2a + 1 + 2b + 1

This can be simplified using the inverse of distributive property

2(a+b) + 2

2(a+b+1)

This is the sum, which is divisible by 2

Nisha and Marcie Drive 20 miles from sisters to hoodoo to go skiing. The speed limit is 75 555 miles per hour. It snowed all nig

slamgirl [31]

If you meant to write this;Nisha and Marcie Drive 20 miles from their sisters to hoodoo to go skiing. The speed limit is 55 miles per hour. It snowed all night, and the safe speed to drive is 40 miles per hour. Explain how you can determine how many more minutes it takes to drive 20 miles at 40 miles per hour in a 55 miles per hour zone.
If you drive 20 miles at 40 mile per hour, then 20 miles divided by 40 miles equals .5.5 times 60 minutes (one hour) is 30 minutesIf you drive 20 miles at 55 mile per hour, then 20 miles divided by 55 miles equals .3636.3636 time 60 minutes (one hour) is 21.8 minutes30 minutes at 40 mph minus 21.8 minutes at 55 mph is 8.2 minutes faster

Will it cost more to rent from Company A or Company B if "Ali" rents the bounce house for 3 hours? 5 hours? 10 hours?

a_sh-v [17]

Answer:

3 HOURS : company A costs more

5 HOURS : Cost is the same

10 HOURS : Company B costs more

Step-by-step explanation:

Company A :

Rental fee = $100

Hourly rate = $20

Company B:

Hourly rate = $40

Cost of renting a bounce house from each company for h hours ;

Company A:

Total cost = 100 + 20h

Company B:

Total cost = 40h

If h = 3

Company A:

100 + 20(3) = $160

Company B:

40(3) = $120

FOR h = 5;

Company A:

100 + 20(5) = $200

Company B:

40(5) = $200

FOR h = 10;

Company A:

100 + 20(10) = $300

Company B:

40(10) = $400

Show work to triangles 2 and 3 explaining why they are right triangles

olganol [36]

Answer:

Step-by-step explanation:

In order for a triangle to be a right triangle, it has to fit into Pythagorean's Theorem:

$a^2+b^2=c^2$ where c is the hypotenuse.

We need to figure out which is the longest side in each of those triangles and that is the hypotenuse.

In the first set, the sqrt of 443 is 21.04, but that is not the longest side; 24 is. So the Theorem formula for that is:

$\sqrt{443}^2+17^2=24^2$ which gives us

443 + 289 = 576, but 732 does not equal 576, so that one is not right.

In the second set, the sqrt of 725 is the longest side, so that formula is:

$\sqrt{725}^2=14^2+23^2$ which gives us

725 = 196 + 529, and 725 does equal 725, so that one is right.

In the third set, the sqrt of 890 is the longest side, so:

$\sqrt{890}^2=19^2+23^2$ , which gives us

890 = 361 + 529, and 890 = 890, so that is a right triangle as well. That's how you know those are right, compared to the first one that is not.
