Which graph represents the function f(x)=x2−49x+7?

Sample size:5

Mean: 53

Mean Absolute Deviation (MAD): 4.4

Answer:

C = 112, A = 150, D = 30, B = 38

Step-by-step explanation:

I solved C first using:

30+38+c = 180 (angles along a straight line should add up to 180 since a whole circle is 360)

-

I solved A by looking across from C.

Angles on opposite sides should mirror each other but A includes 38* + C

Just by doing 112 + 38 you get 150.

-

I solved D by looking at 30*, alternative interior angles are the same so D is 30*.

-

I solved B by taking C (112) and D (30) and adding them together and subtracting from 180.

Interior angles of a triangle should all add up to 180,

112 + 30 + B = 180

From this I got that B was 38.

Alternatively you can find this out by looking at the 38 degrees, corresponding congruent angles are always the same.

I suggest reviewing this angles sheet if you're ever stuck in the future.

Answer:

x = 5, y = 4

Step-by-step explanation:

Solve for one variable. x will be simpler using the second equation.

3x = 15

Divide by 3.

x = 5.

Now put that into the other equation.

4x + 5y = 40

Substitute variable.

4(5) + 5y = 40

20 + 5y = 40

Subtract 20 from both sides.

5y = 20

Divide by 5.

y = 4.

Answer:

When the dimensions are doubled, the volume is eight times the original volume.

Step-by-step explanation:

difference in volume = volume of prism with dimensions doubled / original volume of prism

Volume of a prism = length x width x height

original volume of prism = 7 x 5 x 12 = 420

doubled dimensions of  prism = (7x2) x (5x2) x (12 x 2)

volume = 14 x 10 x 24 = 3360

3360 / 420 = 8

Answer: D When the dimensions are doubled the volume is eight times the original volume​

P - Parentheses

E - Exponents

M - Multiply

D - Divide

A - Add

S - Subtract

PEMDAS, is just an order of operations...

In our order above, Multiplying comes BEFORE addition OR Subtraction...

40 x 0 = 0

Then moving to the front...

40 - 0 = 40...

Lastly, 40 + 1 = 41

Answer is 41

Answer:

-44(b)

Step-by-step explanation:

-4+x=-48

add 4 to both sides

x=-44

Answer: 420 sprouted plants

Step-by-step explanation:

First find the total number of tomato plants in the farm.

= Number of rows * No. of plants per row

= 45 * 14

= 630 plants

2/3 of them have sprouted so the number of sprouted plants is:

= 2/3 * 630

= 420 sprouted plants

Answer:

[tex]\frac{8}{15}[/tex]

Step-by-step explanation:

We require 2 equations with the repeating 3 placed after the decimal point.

let x = 0.5333.. ( multiply both sides by 10 and 100 )

10x = 5.333... → (1)

100x = 53.333... → (2)

Subtract (1) from (2) tus eliminating the repeating 3

90x = 48 ( divide both sides by 90 )

x = [tex]\frac{48}{90}[/tex] = [tex]\frac{8}{15}[/tex]

Answer:

IT IS 8/15

Answer:

D. 150

Step-by-step explanation:

X = W/5

X + W = 180

*If X = 30, and W = 150:

30 = 150/5

30 + 150 = 180

Answer:

Measure of angle XCY is 60°.

Step-by-step explanation:

"Measure of all inscribed angles by the same arc in one segment of the circle are equal"

Using this property in the given circle,

m∠XWY = m∠XCY

60x = 61x - 1

61x - 60x = 1

x = 1

By substituting the value of 'x' in the measure of ∠XCY,

m∠XCY = 61x - 1

             = 61(1) - 1

             = 61 - 1

             = 60°

Therefore, measure of angle XCY is 60°.

Answer:

y = 2

Step-by-step explanation:

Since the y- coordinates of the ordered pairs are all 2

This indicates the line is horizontal with equation y = c

where c is the value of the y- coordinates the line passes through, then

y = 2 ← equation of line

Answer:

X= 1.8

Step-by-step explanation:

If I’m not mistaken then this is how to work it out. X^2 + 4x -9 =0. X^2 + 4x would be 5x. 5x - 9 = 0. +9 on both sides. 5x=9. Divide by 5 on each side. X= 1.8

Answer:

Step-by-step explanation:

you would do 60 divided by 5 which would get you 12

then you multiply 12 by 3 which would be 36

lastly you would multiply 36 by 7 which would get you

252

Answer:

so first you take 7 and you multiply by 60 bc that way you will have the minutes 60x7=420 then you divide 420 by 5 and get 84 then 84x3=252

Answer:

The angle marked E is 120 degrees

Step-by-step explanation:

Here, we want to get the value of the angle marked E

when two triangles are similar/congruent, we have equal angle measures

Using the markings, we can deduce the following relationships;

4y -28 = 83 + y

4y-y = 83 + 28

3y = 111

y = 111/3

y = 37

So, we have;

4y-28 as

4(37) - 28

= 120
