Which expression is equivalent to the expression above?

A. 20+70y
B. 23+9y
C. 26+91y
D. 46+161y

Answer:

x = 59

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] x = 14 [tex]\frac{3}{4}[/tex] ← convert to improper fraction

[tex]\frac{1}{4}[/tex] x = [tex]\frac{59}{4}[/tex] ( multiply both sides by 4 to clear the fractions )

x = 59

The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern

X         Given     Predicted     Residual value

1            3.5           4.06             -0.56

2           2.3           2.09             0.21

3            1.1            0.12               0.98

4           2.2           -1.85              4.05

5          -4.1            -3.82            -0.28

The residual value is calculated as follows using this formula: ( Given - predicted )

1) ( 3.5 - 4.06 ) = -0.56

2) ( 2.3 - 2.09 ) = 0.21

3) ( 1.1 - 0.12 ) = 0.98

4) (2.2 - (-1.85) = 4.05

5) ( -4.1 - (-3.82) = -0.28

Residual values are the difference between the given values and the predicted values in a given data set and the residual plot is used to represent these values .

attached below is the residual plot of the data set

hence we can conclude from the residual plot attached below that the line of best fit is appropriate for the data because the points have no clear pattern ( i.e. scattered )

Answer:

y = 15

Step-by-step explanation:

JKLM ~ PQRS means that quadrilateral JKLM is similar to quadrilateral PQRS.

In similar shapes the corresponding sides have same ratio and the corresponding angles are congruent.

This means angle J is congruent to angle P, K is congruent to Q, L is congruent to R and M is congruent to S. Order of the vertices matters.

Solving for y.

Angle J is congruent to angle P.

5y - 4 = 71 Add 4 on both sides.

5y = 71 + 4

5y = 75  Divide both sides with 5.

y = 15

Answer:

44 degrees

Step-by-step explanation:

angle c = 90 degrees

angle a = 46 degrees

the measure of all sides on a triangle is 180

so to solve for the other side we can do this equation...

180 - (90 + 46) = 44

Angle one and two lie on straight line.

this means there sum is equal to 180°

Given :-

so we can say :-

[tex] \angle1 + \angle2 = 180 \degree \\ 7x + x + 12 = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = \frac{ \cancel{168} {}^{ \: \: 21} }{ \cancel8} \\ x = 21 \degree[/tex]

so angle one = 7x= 7×21 = 147°

angle two = x+12 = 21+12 = 33°

Answer:

c. x < 4

Step-by-step explanation:

-5x < -15x + 40

bring -15x to the left to combine like terms

-5x +15x < -15x + 15x + 40

10x < 40

divided both sides by 10 to get x alone

10x / 10 < 40 / 10

x < 4

===========================================================

Explanation:

There are two approaches here.

Method 1

Focus on the numbers along the top only.

The left arrow points at 50 while the arrow on the right points at 180. Subtract these numbers to get 180 - 50 = 130

------------------------------

Method 2

Focus on the numbers along the bottom row this time.

The left arrow points at 130 and the right arrow points at 0

The difference of which is 130 - 0 = 130

Because we're subtracting off 0, it means we can simply look at only one number without having to do any math. This only works if the other portion of the angle is pointing at 0 or 180.

------------------------------

Notice that 130 degrees is larger than 90, so this angle is obtuse. This means that if you aren't sure whether to go with 50 or 130, it will depend on if it's acute or obtuse.

Answer:

See Down Here

Step-by-step explanation:

We want to get g(x) given that we know f(x) and the graphs for both functions. We will see that the correct option is D:

g(x) = (x/3)^2

By looking at the graph we can see that f(x) and g(x) are two quadratic functions, and g(x) is just a dilation of f(x).

This means that:

g(x) = A*f(x)

Where A is a real number.

We know that:

f(x) = x^2

And by looking at the graph, we also know that g(3) = 1.

Then we can write:

g(3) = A*f(3) = A*3^2 = 1

Now we can solve this for A:

A*3^2 = 1

A*9 = 1

A = 1/9

Then we have:

g(x) = (1/9)*f(x) = (1/9)*x^2 = (x/3)^2

So the correct option is D.

Answer:

(6, 0)

Step-by-step explanation:

Coordinates are written in the form (x, y), where x is the x-axis value that the point is in, in this case 6, and where y is the y-axis value, in this case 0.

Hi!

Answer:

(6, 0)

Step-by-step explanation:

Coordinate point "G" on this graph is on the very bottom. On the X axis, point G is on the 6. On the Y axis, its on the 0, so since the domain, (X) comes first before the range, (Y), you get (6, 0)
