The sum of thirteen and twice a number. Is it linear or nonlinear?
HLP

Answers

The expression for the statement "the sum of thirteen and twice a number" will be given by 13 + 2 x.

We are given a statement:

The sum of thirteen and twice a number.

We need to make an expression for the statement that is being given to us.

Now, first we will let the unknown number be x.

So, twice of a number x will be written as:

2 × x

= 2 x

Now the sum of 13 and 2 x will be written as:

13 + 2 x

Therefore, we get that, the expression for the statement "the sum of thirteen and twice a number" will be given by 13 + 2 x.

The area of the composite figure is 32 mm²

How to find area of a composite figure?

The area of a composite figure can be found by summing the area of the whole shape.

Therefore, the composite figure is a parallelogram and a triangle.

area of the composite figure = area of the triangle + area of the parallelogram

area of the triangle = 1 / 2 bh

area of the triangle = 1 / 2 × 8 × 2

area of the triangle = 16 / 2

area of the triangle = 8 mm²

area of the parallelogram = bh

area of the parallelogram  = 6 × 4

Point P is located 3/5 of the way from point A to point E. Point A is located at (-1, -1) and point P is located


at (-7,5). What are the coordinates for point E?

Answers

By using the line segment formula, we conclude that the coordinates of point E are E(x, y) = (- 11, 9).

How to determine the coordinates of the missing endpoint of a line segment

In this problem we find a line segment of which the coordinates of an endpoint and a point within the segment and in accordance with a segment ratio are known. The coordinates of the other endpoint must be found in accordance with the following expression:

E(x, y) = A(x, y) + k · [P(x, y) - A(x, y)]          (1)

Where E(x, y) is the missing endpoint.

If we know that A(x, y) = (- 1, - 1), P(x, y) = (- 7, 5) and k = 5 / 3, then the coordinates of point E are:

E(x, y) = (- 1, - 1) + (5 / 3) · [(- 7, 5) - (- 1, - 1)]

E(x, y) = (- 1, - 1) + (5 / 3) · (- 6, 6)

E(x, y) = (- 1, - 1) + (- 10, 10)

E(x, y) = (- 11, 9)

Answers

The correct graph for the compound inequality is the third graph.

Graph of Inequality

From the question, we are to determine the correct graph to the given compound inequality

The given compound inequality is

-3 < x ≤ 4

This means

-3 < x and x ≤ 4

That is,

x > -3 and x ≤ 4

The graph of x > -3 will start at -3 on the number line without shading the circle and it will point in the right direction

The graph of x ≤ 4 will start at 4 on the number line, with the circle shaded, and it will point towards the left

Joining the two graphs, we will get a number line starting at -3, unshaded, and ending at 4 shaded.

Hence, the correct graph for the compound inequality is the third graph.

Answers

The probability that the next chew that Qasim will remove from the bag will be lemon chew is 0.17

What is probability ?

Probability is the chance that an event will occur or we can say the chance for how many time an event can occur describes the probability of that event .

Probability =  Preferred Outcome/Total outcome

Probability is always between 0 to 1 i.e. we can say the lowest value of probability is 0 where no outcome is preferable  and the highest value is 1 where all the outcomes are preferable outcomes.

In the question,

If Qasim performs the experiment 52 times of removing a chew from the bag the total outcome = 52

If a pineapple chew was selected 33 times. A lemon chew was selected 9 times. A lime chew was selected 10 times, the probability that  next chew Qasim will remove from the bag will be  the lemon chew  is 9/52 or 0.17 percent.

I just love trees. And there weren't any at all about the asylum, only a few poor weeny-teeny things out in front with little whitewashed cagey things about them. They just looked like orphans themselves, those trees did. It used to make me want to cry to look at them. I used to say to them, 'Oh, you POOR little things! If you were out in a great big woods with other trees all around you and little mosses and Junebells growing over your roots and a brook not far away and birds singing in you branches, you could grow, couldn't you? But you can't where you are. I know just exactly how you feel, little trees.' I felt sorry to leave them behind this morning. You do get so attached to things like that, don't you? Is there a brook anywhere near Green Gables? I forgot to ask Mrs. Spencer that.""Well now, yes, there's one right below the house.""Fancy. It's always been one of my dreams to live near a brook. I never expected I would, though. Dreams don't often come true, do they? Wouldn't it be nice if they did? But just now I feel pretty nearly perfectly happy. I can't feel exactly perfectly happy becausewell, what color would you call this?"She twitched one of her long glossy braids over her thin shoulder and held it up before Matthew's eyes. Matthew was not used to deciding on the tints of ladies' tresses, but in this case there couldn't be much doubt."It's red, ain't it?" he said.The girl let the braid drop back with a sigh that seemed to come from her very toes and to exhale forth all the sorrows of the ages."Yes, it's red," she said resignedly. "Now you see why I can't be perfectly happy. Nobody could who has red hair. I don't mind the other things so muchthe freckles and the green eyes and my skinniness. I can imagine them away. I can imagine that I have a beautiful rose-leaf complexion and lovely starry violet eyes. But I CANNOT imagine that red hair away. I do my best.

I read of a girl once in a novel who had a lifelong sorrow but it wasn't red hair. Her hair was pure gold rippling back from her alabaster brow. What is an alabaster brow? I never could find out. Can you tell me?""Well now, I'm afraid I can't," said Matthew, who was getting a little dizzy. He felt as he had once felt in his rash youth when another boy had enticed him on the merry-go-round at a picnic."Well, whatever it was it must have been something nice because she was divinely beautiful. Have you ever imagined what it must feel like to be divinely beautiful?""Well now, no, I haven't," confessed Matthew ingenuously."I have, often.
