What is the equation of the line in slope-intercept form?

Answer:

36 square units

Step-by-step explanation:

y = x(10-x)

This is a down-opening parabola with axis of symmetry x = 5

Vertex of triangle (5,0)

Base of triangle is the horizontal chord of length 8, endpoints x = (1,9) and (9,9).

Height of triangle = 9

Area of triangle = ½·8·9 = 36 square units

Answer:

You can factor it by taking out the five, since it is a common factor of 5 and 15 (for example: 5(-x - 3) ), you can remove the negative value ( -1(5x+15) ), or your can remove the negative and the 5 (-5(x+3) ).

Answer:

5 total hours

Step-by-step explanation:

3 ÷ 60% = 5

Alan worked 5 hours on the project.

A percentage is a proportion or value that may be expressed as a fraction of 100. Furthermore, the notation "%" is used to denote it.

Let H be the hours he worked on the model.

Alan spent 3 hours building a model for his science project. This was 60% of the total time he spent on the project.

To find the H;

we use the percentage property,

3 = H x 60 / 100

H = 300 /60

H = 5 hours.

Therefore, 5 hours he worked on the project.

Answer: B and D

Step-by-step explanation:

Given

There are 4 red, 2 Green, 3 Yellow, and 1 purple sweet i.e. total of 10 sweets

(a)No of yellow sweet =3

Probability

[tex]P=\dfrac{\text{No of yellow sweets}}{\text{Total no of sweets}}=\frac{3}{10}\\P=0.3[/tex]

In number line, A, B, and C represent 0.2,0.3 and 0.4

For yellow it is B

(b)sweet that is not orange is red, green, yellow, and purple

So, probability

[tex]P=\dfrac{\text{sweet that is not orange}}{\text{Total sweets}}=\frac{10}{10}=1[/tex]

So, D represents it

Answer:

Sam is 24 years old and his mom is 48 years old

Step-by-step explanation:

;)

The present age of Sam is 24 years and the present age of Sam's mother is  48 years

Let the present age of Sam's mother = M

Let the present age of Sam = S

Sam's mother is twice as old as Sam so we can write

[tex]\rm M = 2S.........(1)\\[/tex]

12 years ago  the age of Sam's mother = M - 12

After 12 years the age of Sam = S + 12

According to the given condition

[tex]\rm S + 12 = M-12 ......(2)[/tex]

From equations (1) and (2) solving for M and S we get

[tex]\rm S + 12 = 2S -12\\S = 24\\M = 2\times S = 2\times 24 = 48[/tex]

So we can conclude that the present age of Sam is 24 years and the present age of Sam's mother is  48 years.

Answer:

[tex]y > \frac{1}{3}x - 2[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope, and b is the y-intercept(value of y when x = 0).

In this question:

We have that when [tex]x = 0, y = -2[/tex]. So the line is given by:

[tex]y = mx - 2[/tex]

Finding the slope:

We have two points in the line, which are (-3,-3) and (3,-1). The slope is given by the change in y divided by the change in x. So

Change in y: -1 - (-3) = -1 + 3 = 2

Change in x: 3 - (-3) = 3 + 3 = 6

Slope: [tex]m = \frac{2}{6} = \frac{1}{3}[/tex]

Solution to the inequality:

The solution to this inequality is all the points above the dashed line, which means that the dashed line is not part of the solution. So

[tex]y > \frac{1}{3}x - 2[/tex]

Step-by-step explanation:

The account value can be found using the formula ...

  A = P(1 +rt)

where P is the initial deposit, r is the annual rate, and t is the number of years.

  A = $6000(1 + .035×2) = $6000(1.07) = $6420

The total amount after 2 years is $6420.

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Cross multiply

3 times 20 = 60

4 times x = 4x

now your left with

60= 4x

divide 4 on both sides

15 = x

The numerator of a fraction equivalent to 3/4 that has a denominator of 20 is 15.

A fraction is made up of a numerator and a denominator. Examples of fraction are: [tex]\frac{3}{4} , \frac{1}{2}[/tex]. The numerators are 3 and 1. The denominators are 4 and 2.

In order to determine the numerator, we have to determine the relationship between the two denominators given ( 20 and 4). 20 is a multiple of 4. 20 / 4 = 5. The second step is to multiply 3 by 5 = 3 x 5 = 15.

Answer:

You invested $22,000 in two accounts paying 3% and 5% annual interest, respectively. If the total interest earned for the year was $980, how much was invested at each rate?

Step-by-step explanation:

let x=amt invested at 3% rate of interest.

22000-x=amt invested at 5% rate of interest.  

.03x+.05(22000-x)=980

.03x+1100-.05x=980

.02x=120

x=6000

22000-x=16000

amt invested at 3% rate of interest=$6,000

amt invested at 5% rate of interest=$16,000

The amount invested in the account that yields 3% interest is $21,000 and the amount invested in the account that yields 2% interest is $5000

This can be solved using simultaneous equations. Two equations can be derived from the question :

a + b = 26,000 equation 1

0.02a + 0.03b = 730 equation 2

Where

a = amount invested in the account that yields a 2% interest

b = amount invested in the account that yields a 3% interest

Multiply equation 1 by 0.02

0.02a + 0.02b = 520 equation 3

Subtract equation 3 from equation 2

0.01b = 210

Divide both sides of the equation by 0.01

b = 210 / 0.01 = 21,000

Substitute for b in equation 1

a + 21,000 = 26,000

a = 26,000 - 21,000

a = 5000
