The slope of the line passing through points (-5,-2) and (3,-9) is -7/8.

To solve for the slope, we can use the slope formula:

m = (y2 — y1) / (x2 — x1)

Let (x1,y1) = (-5,2)
(x2,y2) = (3,-9)

Plug in the values into the slope formula:

m = (y2 — y1) / (x2 — x1)

m = [(-9 — (-2)] / [(3 — (-5)]

m = (-9 + 2) / (3 + 5)

m = -7/8

Therefore, the slope of the line is -7/8.

Samantha and Mia are 13 km apart from each other.

<h3>What is Pythagorean ?</h3>

A right triangle's squared sides add up to the hypotenuse's squared length, according to the Pythagorean Theorem.

Mia is 7 kilometers north of Julia's home as she walked at a speed of 7 kilometers per hour.

Samantha walked at an average speed of 11 km/h, and she is now 11 kilometers west of Julia's home.

A right-angled triangle is formed by Julia's house, Mia and Samantha's locations after one hour, and the figure's points.

Hypotenuse of the triangle, which measures distance between the females

the Pythagorean theorem,

H² = P² + B²

H² = 7² + 11²

H² = 49 + 121

H = √170

H = 13.038

H = 13km

Between them, there is a 13 kilometer distance.

−9x (5x+4 ) +10 (x+3) can someone please solve his for me thank u step by step please i really need to find out how to do it

Ivahew [28]

Answer:

-45 $x^{2}$ -26x+30

Step-by-step explanation:

So first you let's divide this equation into three parts.

Part one -9x(5x+4)

Step one: you have to distribute the -9x to the numbers in the parentheses. That would leave us with a -9x*5x = -45 $x^{2}$ and -9x*4 = -36x
Step two: Put the answers together. That would leave us with -45 $x^{2}$ -36x.

Part two 10(x+3)

Step one: you have to distribute the 10 to the numbers in the parentheses. That would leave us with a 10*x = 10x and 10*3 = 30
Step two: Put the answers together. That would leave us with 10x+30

Part three solve

Step one: combine and put together what you have solved for. That would leave us with a -45 $x^{2}$ -36x+ 10x+30
Step two: combine like terms. The like terms here are -36x and 10x. When you combine them you would get -26x.
Step three: Write the equation in standard form. Therefore the answer is -45 $x^{2}$ -26x+30.

5. Which set of ordered pairs below represents a function? 31. {(1,1) (1,- 1) (4,2) (4, -2) (9,3)} b. {(3,4) (3,5) (3,6) (3,7) (

Softa [21]

Answer:

C. {(2,4) (3,4) (4,4) (5,4) (6,4)} is a function.

Step-by-step explanation:

Since there is one value of y for every value of x in {(2,4) (3,4) (4,4) (5,4) (6,4)}, this relation is a function.

Simplify -62 ÷ 12 - 2(-7).<br><br> -17<br> 35<br> 11<br> -35

Rina8888 [55]

I don't know if you know something called PEMDAS

Parentheses
Exponent
Multiply
Divide
Add
Subtract

So you would do the -2(-7) first giving you 14

So now we have -62/12 +14

now you would do -62/12 giving you -5.16666667

and now the equation is -5.16666667 + 14 = 8.83333333

I know for a fact, being in Calculus Honors, that what I did to simplify is correct. Using the Order of Operations, or PEMDAS (Commonly remebered as "Please Excuse My Dear Aunt Sally<span>". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".) to simplify this answer is necessary.

If your teacher wrote this problem please inform him or her of Order of Operations before your classmates use it even though its wrong.</span>
