Answers

Answer 1

Answer:

(2,-5)

Step-by-step explanation:

To solve this, simply substitute the values for x and y. The only one that works is (2,-5).

-5 = -2(2) -1

-5 = -4 - 1

-5 = -5

There are 10 girls for every 12 boys. If there are 50 girls,
how many boys are there?
O a) 60
Ob) 12
O c) 52

d) 62

Answers

We know that 10 x ❺ = 50

So we have to do 12 x ❺ = 60

So the answer is a) 60

Answer: A

why does this keep changing to C????

Step-by-step explanation:

10x5 since there are 50 girls

so we would need to multiply 12 by the same number, so the answer is 60.

1. Exact form: 17/4
Mixed number: 4 1/4
2. Exact form: 372/35
Mixed number: 10 22/35

Answer:

1. 4¼

2. 10 22/35

Step-by-step explanation:

First, find a common denominator, in this case number 1 would contain a common denominator of 4, and for number 2 it could be 35 (7 x 5 = 35).

Then create an equivalent fraction, 1/2 turned into fourths would be 2/4. 2/4 + 3/4 = 5/4, which equals 1 1/4. Then add 1 1/14 + 1 + 2 = 4¼

For number 2, 3/7 = 15/35 and 1/5 = 7/35. Add them and get 22/35, then add the other numbers. 4 + 6 + 22/35 = 10 22/35

Answers

Answer:

D

Step-by-step explanation:

There is no repeated x

The required set of points is y a function of x is C.{(2, 1), (0, 1), (1, 0), (2, 1)}. Option C is correct.

What is set?

Sets are an orderly collection of items in mathematics that can be expressed in set-builder or roster form.

A function is a set of ordered pairs where each value of x has only one corresponding value of y. In other words, for a function, there can be only one value of y for each value of x.

So, among the sets of points given, set D, A, and C is not a function of x because the value x=1 has two corresponding values of y.

Therefore, the set of points in which y is a function of x is set C.{(2, 1), (0, 1), (1, 0), (2, 1)} because, for each value of x, there is only one corresponding value of y.

If f(x) = 9x - 2 and g(x) = 2x², what is the value of f(4) - g(4)

Answers

9514 1404 393

Answer:

  f(4) -g(4) = 2

Step-by-step explanation:

Fill in the given values for x and do the arithmetic.

  f(4) = 9·4 -2 = 34

  g(4) = 2·4^2 = 32

Then ...

  f(4) -g(4) = 34 -32

  f(4) -g(4) = 2

ANSWER= 2
Explanation
Plug in the numbers in the parentheses for x EX: f(4)=9(4)-2= 34 and g(4)=2(4)^2 —-> g(4)=2(16)= 32 so 34-32= 2

a manufacturer says that the diagonal measurement of a laptop computer is 16 inches. Find the relative error of this measurement to the nearest tenth.

A. 0.6%

B.1.6%

C.3.1%

D.6.3%

Answers

Answer:

As this is incomplete, it lacks the value of actual error.

Here, we do not know the actual value. so let's assume it is 1 inch

Relative Error = 6.25 % ≈ 6.3% = D

Step-by-step explanation:

As this is incomplete, it lacks the value of actual error.

We are asked to calculate the relative of the measurement.

Relative error formula = Actual error/Measurement x 100

Here, we do not know the actual value. so let's assume it is 1 inch

Actual value = 1 inch

Measurement = 16 inch

Relative Error = 1/16 x 100

Relative Error = 6.25 % ≈ 6.3% = D

D. 6.3%

When do you use point slope form

Answers

Answer:

It can be used as a preference

Answer:

You use point-slope form when you know (or can determine) the slope and the coordinates of one point on the line.

Step-by-step explanation:

You use point-slope form when you know (or can determine) the slope and the coordinates of a point. So, either you are given the slope of the line and a point on the line, or you are given two points on the line and you use the points to determine the slope.

Explain your reasoning. Provide one example of figurative language in The Blackness story:Why is it so quiet? Why can't I move? And why is it so dark? I try to recall where I am, but I cannot remember. Blackness surrounds me.I hear a familiar voice that makes my heart flutter like a thousand butterflies. It is the voice of my friend, Maddy. She visits her grandparents here on the Gulf of Mexico every summer. She usually brings me crumbs, but today, I cannot smell anything except the sour smell of oil. Her voice sounds worried, different from the usual cheerful greeting that she calls me with every day at dusk. I try to turn towards her, but I can't move very well. My feet feel mired as if in quicksand.I hear her come closer. Her words help me understand that something has happened to my home."Oh, grandma! What is all this? They are all covered in it! It's black. Ugh! The smell is so strong I can't stand it." Maddy's tears stream down her face, mingling with mine. I hear her crying, but all is dark, like a moonless night. Where is the smiling sun? I try to stretch out to feel the warmth, but my wings do not respond. Dazed, I call out to my friends hoping they will find me in the blackness, but everything is so still. I hear nothing, except for Maddy's desperation. Her sobs, uncontrollable."Go get some towels, Maddy. Run!" Her grandma tells her, a quiet urgency in her voice. "Hey little one," grandma coos as she bends over me. I can feel her breath on my head. "We've got you and you are going to do all we can for you." All they can? I hear Maddy's hurried footsteps and feel the towel's softness enveloping me as she picks me up in her arms. She is gentle, her sobs quieting as she takes me to her home, seemingly miles and miles from my nest along the shoreline.I hear the phone ring. I hear the news on the television. "Spill...oil...negligence...BP...blame..." "What are we going to do?" I hear the door banging and neighbors' voices, shrill and urgent, coming in and out of the house. All of the sounds tell me that the emergency is intensifying.I still cannot see anything. Maybe it is good that I cannot see. If I could, I might see my home, blackened with the oil of a mishandled well deep in the ocean. I would see my friends, covered in slick crudeness. I would desperately observe the choking, billowing smoke, polluting the Gulf sky, my home. I would see my family unable to fly through the air, unable to dive into the ocean for the delicious meals we used to find there. I fear our fish are no more; they are stuck in the depths of the black, watery grave. What are we going to do? What are we going to do? I hope the humans will do something to bring light to all of the blackness.I hear Maddy, making sweet, soothing sounds as she begins to clean my feathers gently. I hear that sound often.
