Answer: It's a right triangle

Answer: It is a right triangle.

the attachment shows the graphed triangle.

Step-by-step explanation:  The slope of the line between coordinates (-2,-3) and (2,1) is +1  rise/run is 4/4

The slope of the line between points (2,1) and (5,-2) is -1 rise/run -3/3

These slopes are perpendicular to each other, so they form the right angle of this triangle.

Answer:

Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]

Step-by-step explanation:

We need to u se a vertical format to subtract the polynomials.

The polynomials given are:

[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)[/tex]

Now, solving

For, subtraction, the sign of the terms [tex]7x^2 + 2x - 3[/tex] will be changed. - will convert to + because (-)(-) = + and positive sign will be converted to negative (-)(+) = -

The sign with the resulting term will be the sign of term that has greater coefficient. For example if we are subtracting 3x^2 and (-7x^2), the result will be -4x^2 because 7 has negative sign. (term has greater coefficient)

[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)\\\\:\:\:\:\:\:\:-\:\:\:\:-\:\:\:\:\:+\\-----------\\-4x^2-4x+5[/tex]

So, Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]

Answer: $‭6,861.44

Step-by-step explanation:

Car was bought 3 years ago for $12,000.

Value decreases by 17% every year.

Current value is:

= 12,000 * (1 - 17%)³

= $‭6,861.44

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out. We are informed that he expression 42 + 57 shows how much money Nate spent at the store. This means that she spent (42 + 57) = 99.

The expression that also shows how much money Nate spent would be a number that when you add will give you 99. This will be

• 66 + 33

• 22 + 77

• 40 + 59 etc

Answer:

i dont know which one to choose but chicken tenders

Answer:

Chicken tenders.

Step-by-step explanation:

Chicken nuggets are the gross consumption of organs including lungs and others mushed together and fried. In return kids run to it because (most) kids only eat gross stuff. This made the marketing campaign SKY ROCKET with kids everywhere trying to get a bite. FORCING their poor parents to get them that disgusting mush. And then dip it in ketchup. Which is NOT a fruit or veggie. (As the school system thinks they are a veggie.)

While chicken tenders are chopped off the chicken meat then rolled in bread crumbs. And then deep fried to make a crispy exterior with a delicious tender interior.  Without getting mushed together with other things.

Also you never know what they put in that chicken nugget since its mushed together ‍♀️.

Answer:

34.5 feets

Step-by-step explanation:

Length of ladder = 37 feet

Angle between ladder and top of building = 21°

Since ladder makes a right angle with the foot of the wall;

Angle the ladder makes with the ground :

(90° + 21° + θ) = 180°

111° + θ = 180°

θ = 180° - 111°

θ = 69°

To obtain the height, x of the building reached by the ladder ;

Using Pythagoras :

Sinθ = opposite / hypotenus

Sin 69° = x / 37

x = 37 * sin 69°

x = 37 * 0.9335804

x = 34.542475

x = 34.54 feets

Hence, the height up the building reached by the ladder is 34.5 feets

Answer:

267.5 miles

Step-by-step explanation:

We start with the formula for speed:

speed = distance/time

Now we solve it for distance:

distance = speed * time

65 mph for 2.5 hours + 70 mph for 1.5 hours

distance = 65 * 2.5 + 70 * 1.5

distance = 162.5 + 105

distance = 267.5

Answer: 267.5 miles

Answer:

$1560

Step-by-step explanation:

x = salary

y = weekly

255 = 1/12 x + 125

3060 = x + 1500

x = 1560

How many solutions for y=x-1?

The graph of  y=x−1  in the  xy -plane is a straight line. Each point on this line represents a solution to the equation.

Let  x=t  where  t  is a real number. Then any point on the line is of the form

(x, y)=(t, t−1).

There is an infinitude of these points.

Step-by-step explanation:

Answer:

y = 0x +6 or y = 6 if simplified

Step-by-step explanation:

y=mx+b is slope intercept formula

m is the slope which we know ( 0 ) and we know the line passes through (5,6) so all we need to figure out is b

so plug it in and solve:

6 = 0(5) +b

6 = b

so 6 is b and now we know the equation

y = 0x +6 or y = 6 if simplified

Answer:

-1 or B

Step-by-step explanation:

Answer:

p ≤ 1

Step-by-step explanation:

Given

7(3 - p) - p ≥ 8p + 5 ← distribute left side and simplify

21 - 7p - p ≥ 8p + 5

21 - 8p ≥ 8p + 5 ( subtract 8p from both sides )

21 - 16p ≥ 5 ( subtract 21 from both sides )

- 16p ≥ - 16

Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity

p ≤ 1

I would give you the answers but then that wouldn't help you, so sorry in advance.

We already know that the slope of a line is rise over run

or y1-y2/x1-x2

But that only gives us the slope

What if we want to have an equation that shows what points it passes through as well

Well, that's basically what slope-intercept is.

We can use this simple formula (simple because there's much more complicated formulas)

y=mx+b where y equals the y coordinate, x equals the x coordinate, m equals the slope, and b is the y-intercept.

As an example, I'll do the first one for you.

y=mx+b

Plug in what we know

y=1x+4

You can simplify this down to

y=x+4, since 1 is identity property.

Then, you make up what x is, and your like "x is 0", if x=0, then y=4, so it'll work like that, but I'm pretty sure you don't have to show that.

And as a treat, I'll do the second one as an example:

y=mx+b

Plug in what we know

y=2x+(-2)

Simplify

y=2x-2

Same thing here, you make up what x is, and your like "x is 0", if x=0, then y=4, so it'll work like that, but I'm pretty sure you don't have to show that.

Hope this helps, let me know if you have any questions,

Answer:

54 miles per hour.

Step-by-step explanation:

Just divided 621 by 11.5.

You would take 621 and divide that by 11.5 and you would get 54 mph I believe, if I am wrong please let me know so I can take down my answer! have a great and God blessed day! :D

Answer:

Step 2

Step-by-step explanation:

sorry if it's wrong but my mom helped me figure it out

Answer:

First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).

Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

Answer:

90 candies

Step-by-step explanation:

15/ 1/6=90

90*1/6=15

Answer:

90

Step-by-step explanation:

Let x = number of M&M's in the bag

      (1/6) * x  = 15               [in word (story) problems, "of" usually means multiply]

              x = 90             [multiply both sides by 6]

Answer:

He is at sea level after 34 seconds

Step-by-step explanation:

The height at sea level is given as 0 meters

So the change in height would be;

0- (-17) = 17 meters

There is a gain of 0.5 meters in 1 second

So, the time taken for it to gain 17 meters will be 17/0.5 = 34 seconds
