Which of the points shown below are on the line given by the equation Y = X +3? Check all that apply. A). Point A : (-1, 2) B). Point B : (-1, -2) C). Point C : (2, 5) D). Point D : (-3, 0) Please No jokes I really need help :))
Answer:
Point APoint CPoint DStep-by-step explanation:
The points are in the format (x , y) so given x which is the first figure, you can find y by following the formula.
Y in the point needs to satisfy the criterion of X + 3.
Point A
x = -1
y = x + 3
= -1 + 3
y = 2
Point A satisfies the equation as y from the equation is y in the point given.
Point B
x = -1
y = x + 3
= -1 + 3
y = 2
Point B does not satisfy the equation and so is not on the line.
Point C
x = 2
y = 2 + 3
y = 5
Point C satisfies the equation as y from the equation is y in the point given.
Point D
x = -3
y = -3 + 3
y = 0
Point D satisfies the equation as y from the equation is y in the point given.

Use the graph of f to estimate the local maximum and local minimum. (5 points)
A piecewise graph is shown with a line increasing to 0,-2 terminating at that point and a curve starting at 0,0 and intercepting the x axis at 0, pi, and 2pi.
a) Local maximum: (0,-2); local minimum: (0,0) and (π,0)
b) Local maximum: pi ; local minimum: three pi over two, negative 1
c) Local maximum: (0,0) and pi over two, 1 ; local minimum: (0,0) and three pi over two, negative1
d) Local maximum: (0,0) and pi over two,1 ; local minimum: three pi over two, negative1
Answer:
b) Local maximum: pi ; local minimum: three pi over two, negative 1

Two savings accounts earn simple interest. Account A has a beginning balance of $500 and grows by $25 per year. Account B has a beginning balance of $750 and grows by $15 per year.
Answer:
After 25 years both the accounts will have the same balance.
Step-by-step explanation:
Let t years, both the account will have the same balance.
As account A has a beginning balance of $500 and grows by $25 per year.
So, the total balance of account A after t years = 500+25t
Similarly, account B has a beginning balance of $750 and grows by $15 per year.
So, the total balance of account A after t years = 750+15t
As both the accounts has the same balance, so
500+25t= 750+15t
25t-15t=750-500
10t=250
t=250/10
t=25 years
Hence, after 25 years both the accounts will have the same balance.

If y < -2x + 10 which of the following are viable solutions?
Answer:
y < 12x
....................
The shaded region in the graph of y < -2x + 10 represents the viable solution ordered pairs.
What is a expression? What is a mathematical equation? What is inequality?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. An inequality is used to compare two or more mathematical expressions.
We have the following inequality -
y < -2x + 10
We can write -
y < -2x + 10
Refer to the graph of the inequality attached. The shaded region represents the viable solution ordered pairs.
Therefore, the shaded region in the graph of y < -2x + 10 represents the viable solution ordered pairs.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 9N acts on a certain object, the acceleration of the object is 3 m/s2 . If the force is changed to 6N , what will be the acceleration of the object?
Answer:
The acceleration is 2m/s^2
Step-by-step explanation:
Given
Variation: Direction Variation
Represent Force with F and Acceleration with A
When
[tex]F= 9N; A=3m/s^2[/tex]
Required
Find A when F =6N
The variation can be represented as:
[tex]F \alpha A[/tex]
Convert to an equation
[tex]F = kA[/tex]
Where
[tex]k = variation\ constant[/tex]
When
[tex]F= 9N; A=3m/s^2[/tex]
We have:
[tex]9N = k * 3m/s^2[/tex]
Solve or k
[tex]k = \frac{9N}{3m/s^2}[/tex]
[tex]k = 3kg[/tex]
When
[tex]F = 6N[/tex]
We have:
[tex]F = kA[/tex]
Substitute 6N for F and 3kg for k
[tex]6N = 3kg * A[/tex]
Solve for A
[tex]A = \frac{6N}{3kg}[/tex]
[tex]A = 2m/s^2[/tex]

Suppose there is a 1.8 Farenheit drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 62.4 farenheit , what will be the temperature when the plane reaches an altitude of 8,000 ft. ?
Answer:
48° FStep-by-step explanation:
Let the altitude on the ground be 0 ft
Temperature at 8000 ft is:
62.4 - 1.8°*(8000 - 0)/1000 = 62.4 - 1.8*8 =62.4 - 14.4 =48° FAnswer:

Nicholas wants to buy a new computer that is on sale for $899. His parents will loan him the money if he repays them. He has $225 in his savings account and plans to work as a camp counselor to earn money during the summer. If he earns $35 per day, how many days will Nicholas have to work in order to fully repay his parents?
Answer:
20 days
Step-by-step explanation:
899- 225= 674
674÷ 35= 19.257....
which you would round it up to 20 because he would have to work the extra day because you need more than less.
During a Middle School basketball season, Antonio made 17 of his free throws out of 20. What percent of his free throws did he make?
I see a fraction. Don't you. Here it is 17/20. Now, let's divide 17 by 20 to get a decimal number, which is 0.85. Next, we multiply 0.85 by 100 to get the percent because that is what the question desires for us to express our answer. As a result, we get 85%, and Antonio made 85% of his free throws. By the way, I hope my response helps you.
Step-by-step explanation:
1 way is to do 17/ 20 using long division...
0. 85
20⟌1700 ( I tried my best)
- 160
100
So the answer would be 85%
Another way to do it is by bringing the denominator to 100
Since 20 is 1/5 of 100, you would have to multiply the numerator and denominator by 5
17/ 20 = 17*5/ 20*5 = 85/ 100
And you get 85%
Hope this helps!!!

What is X?[tex]\frac{x-2}{3} = \frac{-7}{18}[/tex]
Answer:
x = 5/6
Step-by-step explanation:
Cross multiply.
18(x - 2) = 3(-7)
Divide both sides by 3.
6(x - 2) = -7
Distribute the 6.
6x - 12 = -7
Add 12 to both sides.
6x = 5
Divide both sides by 6.
x = 5/6
Answer: x = 5/6
[tex]\dashrightarrow\:\:\sf \dfrac{x - 2}{3} = \dfrac{-7}{18} \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf (x - 2) \times 18= -7 \times 3 \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf 18x - 36 = -21 \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf 18x = -21 + 36\\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf 18x = 15\\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf x = \dfrac{15}{18} \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf x = \dfrac{5}{6} \\ \\ \\ [/tex]
