S:{−2, −5}

Answers

Answer:

S:{−2, −3}

Step-by-step explanation:

Determine which integers in the set S: {−2, −3, −4, −5} will make the inequality 2p − 8 < 5p + 4 true.

S:{−2, −3}

S:{−3, −4}

S:{−4, −5}

S:{−2, −5}

We will substitute in the integers and find the ones that make the equation true:

2p − 8 < 5p + 4 when p = -2

2(-2) − 8 < 5(-2) + 4

-4 − 8 < -10 + 4

-12 < -6 TRUE

____________________

2p − 8 < 5p + 4 when p = -3

2(-3) − 8 < 5(-3) + 4

-6 − 8 < -15 + 4

-14 < -11 TRUE

____________________

2p − 8 < 5p + 4 when p = -4

Determine which set of side measurements could be used to form a right triangle.


9, 11, 13

6, 12, 17

square root of 8, 5, square root of 17

square root of 2, square root of 7, 9

Answers

The set of side measurements that could be used to form a right triangle is √8, 5, and √17 option (C) is correct.

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

It is given that:

The side length of the triangle is shown in the option:

As we know,

Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

Using Pythagoras' theorem:

From option(C):

√8, 5, and √17

(√8)² + (√17)² = 5²

8 + 17 = 25 (True)

Thus, the set of side measurements that could be used to form a right triangle is √8, 5, and √17 option (C) is correct.

I need help on numbers 20 and 22

Answers

Answer:

20) ∠2 = 55°

22) ∠6 = 129.5°

Step-by-step explanation:

20) ∠2 = 55° (assuming lines a and b are parallel, ∠4 and ∠2 are alternate interior angles, which implies they are parallel.)

22) ∠6 and ∠7 are co-exterior angles, which implies they add up to 180°. Therefore, ∠6 = 180 - ∠7, ∠6 = 180 - 50.5, ∠6 = 129.5°.

Answer:

20) ∠2 = 55°

22) ∠6 = 129.5°

What is the product of 5 and 1/3? Write your answer in simplest form.
1. 15
2. 1/15
3. 15/3
4. 1 2/3

Answers

Answer: 1 2/3

Step-by-step explanation:

To find the product of fractions, you multiply the denominator and the numerator. 5 isn't a fraction so you can make it a fraction by keeping 1 as the denominator. So 5 as a fraction is 5/1. 5/1 times 1/3 = 5/3. 5/3 as a mixed number is 1 2/3.

Product means to multiply. So, 5 x 1/3 = 5/3 or in decimal form: 1.67

Step-by-step explanation:

(4x7)+(4x70)+(4x600)=2708

(70x7)+(70x70)+(70x600)=47,390

Add=50,098

677 x 70 = 47390

677 x 4 = 2708

47390 + 2708 = 50098

Write down the equation of the line in slope-intercept form. Underline the slope and circle the y-intercept in each equation.

The slope =
The y-intercept =

Answers

Answer:

The slope-intercept form = y=x-3/2

The slope = 1

The y-intercept = -3/2

Step-by-step explanation:

4y=-6+4x

Turn 4y=-6+4x into slope-intercept form.

4y=-6+4x    Divide 4 from each

4y/4=-6/4+4x/4

y=-3/2+x

Since the slope-intercept form is y=mx+b

y=x-3/2

The veterinarian told Sally that her cat needs to lose 5 pounds. A healthy weight loss for her cat would be about 1 pound every 2 weeks. To model this situation, she graphed the following line, where y represents the number of pounds left to lose and x represents time in weeks.
The equation for this line is y =___ x + ___ . If she continues the line, she would see that it would take___weeks for her cat to lose 5 pounds

Answers

Answer:

You already know the answer, but anyway it's 10 weeks with y = 0,5x + 0

Step-by-step explanation:

Basically what you have to do to find the equation is to pick 2 random points on the line drawn to get the solution.

I take (0, 0) and (2, 1) because they are the simplest ones.

The equation for finding a line with 2 points (that actually are 4 coordinates x1 = 0, y1 = 0, x2 = 2 and y2 = 0) is:

(x + x1) \ (x2 + x1) = (y + y1) \ (y2 + y1)

that becomes:

(x + 0) \ (2 + 0) = (y + 0) \ (1 + 0)

simplyfing this, it becomes:

x/2 = y ---> y = 1/2x that you can write on the answer page as y = 0,5x + 0

Answer: The equation for this line is y = -1/2 x + 5. If she continues the line, she would see that it would take 10 weeks for her cat to lose 5 pounds.

What is the slope of the line passing through the points (−3, 4) and (2, −1)?

Answers

Answer: -1

Step-by-step explanation:

The slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate of that line.

The formula to find the slope is

m = (y2 - y1)/ (x2 - x1)

Where (x1, y1) and (x2, y2) are the two points

The two points given are (-3, 4) and (2, -1)

Substituting it in the formula

m = (-1 - 4)/ (2 - (-3))

By further calculation

m = -5/ (2 + 3)

So we get

m = -5/5

m = -1

Therefore, the slope of the line is -1.

hello! the slope would be -1. since I can’t explain with words, I did it on paper.

Thank you!

Answers

hey...can we become friends??

Answer:

-16-5-22-45-45-146-19-44

Step-by-step explanation:

This is an example for all orders of operations

1. We need to know P.E.M.D.A.S.

(P)lease(E)xcuse (M)y(D)ear (A)unt(S)ally

2. PEMDAS is the acronym for the order in which you solve things:

(P)lease = Parentheses Ex: (x+y)(E)xcuse = Exponet Ex: [tex]x^{2}[/tex](M)y = Multiplication Ex: A×B(D)ear = Divide  Ex: A÷B(A)unt = Addition Ex: A+B(S)ally = Subtract Ex: A-B

3. Now that we know how the order of operations works let to a problem:

Ex: 7×8+(7×2+3)-(5+7)

1. First, we are gonna solve what is inside the parentheses.

2. We will do the first one : (7×2+3)

3. We are gonna use the order of operations to know what we solve first.

It looks like multiplication is firstso we do 7×2 and that =14

4. So now our parentheses should look like this:

(14+3)

5. Now the whole problem should look like this :

7×8+(14+3)-(5+7)

6. Now we solve (14+3). That =17. Our whole problem should be like this

7×8+(17)-(5+7)

7. Now that we have solved the first parentheses we have to solve the second one: (5+7). that is 12. here is what it looks like in the whole problem:

7×8+(17)-(12)

8. Now that we have solved the parentheses we can solve the next one. That is exponents. We don't have any exponents so we can go to the next and that is multiplication.

7×8That is 56the whole problem is now 56+(17)-(12)

9. Now we have solved the multiplication we need to do the division. There isn't any so we can go to addition now.

56+17that is 73the whole problem is now 73-12

10. Now we do the subtraction

73-12 and that equals 61

11. The answer is now solved

NOTE if you have something like this: 3(-3) it means 3×-3
