Answer:

The answer is D.

Step-by-step explanation:

Answer:

C.)

Step-by-step explanation:

The graph is positive this time, so right away you can eliminate A and B.

If y=2x, the graph would be much steeper so the answer is C.) you can also check by graphing it in desmos.

Answer: C: 1/2

Step-by-step explanation:

Rise over run tells us that this graph is going up 1 and right 2. Since it’s going up and right it’s going to be positive and since we do rise over run on our slope fraction, that leaves us with C, 1/2.

Answer:

42

Answer:

[tex]\displaystyle f(x)=\frac{10}{169}\left(x-8\right)^2-1[/tex]

Step-by-step explanation:

We can use the vertex form of a quadratic, which is given by:

[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]

Where (h, k) is the vertex.

Since we are given that the vertex is (8, -1), h = 8 and k = -1. Substitute:

[tex]f(x)=a(x-8)^2-1[/tex]

Next, we are given that the parabola passes through the point (-5, 9). So, when x = -5, y = 9:

[tex]9=a((-5)-8)^2-1[/tex]

Solve for a:

[tex]9=a(-13)^2-1[/tex]

So:

[tex]\displaystyle a=\frac{10}{169}[/tex]

So, the equation of our parabola is:

[tex]\displaystyle f(x)=\frac{10}{169}\left(x-8\right)^2-1[/tex]

Answer:

The equation of our parabola would be:

f(x) = 10/169(x - 8)[tex]^{2}[/tex] - 1

Step-by-step explanation: there

Answer:

[tex]y= 2x - 3[/tex]

Step-by-step explanation:

rearrange equation into slope-intercept form

isolate y by subtracting x from both sides

[tex]2y=-x+14[/tex]

divide two from both sides

[tex]y= -\frac{1}{2}x+7[/tex]

here, we can note that the slope is -1/2, which to be perpendicular means it needs the negative inverse of slope

in other words, flip the fraction and take the negative of it, which gives m = 2

therefore plugging the given coordinates (6,9) and slope m = 2 into

[tex]y-y_{1} = m(x-x_{1} )[/tex]

therefore, we get

[tex]y-9=2}(x-6)[/tex]

distribute 2

[tex]y-9 = 2x - 12[/tex]

add 9 to both sides

[tex]y= 2x -3[/tex]

Answer:

y = 2x-3

Step-by-step explanation:

find the slope intercept first by isolation the y in the first equation

then because its asking for the perpendicular equation you will flip the x in the slope intercept equation.

now youll want to plug in (6,9) into y = 2x + a

and you will get -3

then youll have your answer

Answer:

D

Step-by-step explanation:

6 x 1/3 = 2

1/3 x (12-3) = 2 x 9

2 x 9 = 18

A = 2 (12/3) = 2 x 4 =  8

B = 2 x 15 = 30

C = 2 x 36 = 72

D = 2 x 9 = 18

Answer:

Naman is 12 years old

Step-by-step explanation:

This means his sister is 3 which means in 20 years Naman will be 32 and his sister will be 23. Double 23 and you get 46 and 46 - 32 is 14

Answer:

50/100 and 50%

4/5 and 80%

Step-by-step explanation:

Hope it helps you in your learning process

Answer: I would go with 50/100 and 50%, And another will be 4/5 and 80%

Step-by-step explanation: Because 50/100=50% and if you had 2+2+2+2 it would equal 80% put the zero at the end of your process.

Answer:

3

Step-by-step explanation:

if you use the system of equations, it is 3.

Answer: 3

Step-by-step explanation:

28÷7=4

6÷3=2

4+2=6

6*1/2=3

The distance between points  (2, -6) and (2, 5) is d = |-6| + |5|.

In the first step, we plot the two points. Then, connect the two points. Count the distance between Quadrant I and Quadrant IV.

Quadrant I contains 5 units and quadrant IV contains 6 units. We know that the vertical line denotes the y-value. Therefore, we take the Quadrant IV value as -6.

Since, we use the determinant sign the result will be d = |-6| + |5|.

To find the distance between two points:

Answer:

Below in bold.

Step-by-step explanation:

Let cost of sandwich = s,  juice = j and salad = d.

2s + j = 500     (A)

s + d = 510       (B)

d + j =  530      (C)

Equation  (C) - (B)   ( to eliminate d):

j - s = 20          (D)

(A)  - (D) =   (to eliminate j):

2s - (-s) = 480

3s = 480

s = 160

A sandwich costs E 1.60.

Ok soo for the first one we're gonna use sine, (remember SOH CAH TOA) since we know the value of the hypotenuse.

Sin37° = x/9.3

0.6018=x/9.3

x= 5.59674

The last one we'll use cosine because we know the value of the side adjacent to 96°.

Cos42°=5.1/y

0.7431=5.1/y

y= 6.86272692

I assume it has you round your answers to the nearest tenth so the first one would be 5.6 and the second would be 6.9 .

Hope this helps!

Answer:

Step-by-step explanation:

Hi,

So from Andre's perspective, if he receive money that would be positive (cuz that will be adding to his collection) whereas, if he has to give money away that would be negative (cuz he would have to pay out of his pocket).

Think about it like this, people generally feel positive when they receive money and feel negative when they give away money. Apply this same concept.

Therefore,

A) Andre received money so = $25

B) Andre earned money so = $18

C) Andre had to give money away to buy the book so = - $10

D) Zero (0) would mean that he did not gain or lose any money.

Answer:

a. +25

b. +18

c. -10

d. 0 could represent the starting amount.

Step-by-step explanation:

Andy gets money from his uncle, so he is earning money, which makes it a positive.

Similar to b, Andy earns $18. He is earning it, so it is positive.

With C, he is losing money by paying for something, so it is negative.

Answer: 26%

Step-by-step explanation:

20+52+34+71+23= 200

52/200 = 26/100

Answer:

26% of the jelly beans are yellow

Step-by-step explanation:

To find this we add up all the jelly beans which is 200 jelly beans

Then we divide it by the number of yellow jelly beans which is 52/200

which then equals .26. In a percentage that is 26%

Answer:

2544 ft

Step-by-step explanation:

First, find the area of the pool.

A= πr²

if we fill in the radius, use 3.14 for pi, and solve for A, that's

A=(3.14)(20.5)²≈1319.585

The area of the pool is roughly 1319.585 ft

Now, we find the area of the triangle

A=(ab)÷2

put in 'a' and 'b' (the triangle legs) and solve

A=(84×92)÷2=3864

Finally, subtract the area of the pool from that of the triangle

3864-1319.585=2544.415 which rounds to 2544 ft

hopefully that helps and you might want to double check but that's what I got :)

Step-by-step explanation:

Common Factor

Divide both sides of the equation by the same term

Use the quadratic formula

Answer:

-1 or -4

Step-by-step explanation:

first all you have to do is to multiply 12 by 3b² to give you 36b² and then find a number(x) multiplied by another number(y) to give you 36b² and those two numbers must sum up to give you 15b

doing this, we would have our two numbers to be

12b and 3b

replace these two numbers with 15b in the equation

3b² + 12b + 3b + 12=0

(3b²+12b) + (3b+12)=0

3b(b+4)+3(b+4)=0

note: the numbers in the brackets must be the same

(3b+3)(b+4)=0

therefore, 3b + 3= 0 or b + 4= 0

3b+3= 0

3b=-3

b=-3/3

b=-1

or

b+4=0

b=-4
