Step-by-step explanation:

Answer:

The answer is D: 42

Step-by-step explanation:

Angle 7 and angle 138 are supplementary and must add up to 180

Angle 7 is congruent to angle 6 through CPCTC (Corresponding Parts of Congruent Triangles are Congruent)

Angle 7 and 6 are corresponding angles

you must find angle 7 becasue Angle 7= Angle 6

angle 7=x

138-x=180

solve for equation you get

x=42

Angle 7 = 42

so that means that Angle 6 is 42

Answer:

Subtract 2k from both sides.

4k−3−2k=2k+5−2k

2k−3=5

Add 3 to both sides.

2k−3+3=5+3

2k=8

Divide both sides by 2.

2k /2 =8/2

k=4

Answer 16

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

The equation would be 130% x N = 20.8

To solve you would have to switch the equation around and to do that you would divide. 130% is the same as 1.30 or 1.3

20.8 ÷ 1.3 = 16

N = 16

Answer:

-4/9

Step-by-step explanation:

I used a calculator.

5/6(−8/15) in simplest form is -4/9.

A fraction is written in the form of a numerator and a denominator.There are two types of fractions. One is proper fraction in which numerator is less than the denominator and another one is improper fraction in which denominator is less than the numerator.All fractions can be written in the form of p/q, where q ≠ 0 cause anything divided by 0 is undefined.

According to the given questions we have to multiply two fractions        (5/6)(-8/15) which is

= -40/90.

= -4/9.

Answer:y=-1/4x+5/4

Step-by-step explanation:

Perpendicular means the slope has to be the negative reciprocal.

Since the slope is currently 4, the perpendicular slope is -1/4.

It also has to pass through the point 1,1 , so you just plug x in which will be

1*-1/4=-1/4. from 1 to -1/4, its 5/4, so that's your b in y = mx+b

The equation will then be y=-1/4x+5/4

Answer:

C) 18

Step-by-step explanation:

All you have to do is solve the equation.

2.25x + 5 = 45.50 (subtract 5 on each side)

2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)

x = 18

40.50/2.25 = 18

Answer:

18 Miles

Step-by-step explanation:

If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.

Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

Answer:

x = 3.

Step-by-step explanation:

log4 (3x - 1) = log4 (x + 5)  Since they are both logs to the base 4:

3x - 1 = x + 5

2x = 6

x = 3.

On solving the logarithmic equation, we find that x = 3.

A logarithmic equation is an equation that involves the logarithm of an expression containing a variable.

Answer:

B?

Step-by-step explanation:

The graph y = 2x + 5 can be represented by the image attached below.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, An equation y = 2x + 5, we can graph this by assuming some arbitrary values of 'x' that correspond to some arbitrary values of 'y'.

When x = 0, y = 5.

x = 1, y = 7 ⇒  (1, 7).

x = 5, y = 15 ⇒ (5, 15).

x = - 5, y = - 5 ⇒ (- 5, - 5).

x = - 2, y = 1 ⇒ (- 2, 1).

Step-by-step explanation:

You need to find the unit rate which is 10.50$. Then you would multiply it by 10.

Answer:

20x - 21y + 14

Step-by-step explanation:

1/5(150x - 80y + 50 - 50x- 25y + 20)

Step 1 - Distribute

1/5 • 150x = 30x

1/5 • (-80y) = -16y

1/5 • 50 = 10

1/5 • (-50x) = -10x

1/5 • (-25y) = -5y

1/5 • 20 = 4

Step 2 - Combine Variables

30x - 10x = 20x

-16y - 5y = -21y

10 + 4 = 14

Step 3 - Arrange the Set of Numbers

20x - 21y + 14

This is the simplified expression, I know it is correct, I doubled checked on my expression calculator.

Answer: The triangles are similar

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

Explanation:

The square markers show that

angle RPQ = angle RST = 90 degrees

So that's one pair of congruent angles. Another pair of congruent angles is what you see in the diagram below. The angles marked in red are congruent alternate interior angles. Alternate interior angles are congruent when we have parallel lines like this.

Since we have two pairs of congruent angles, we can use the AA (angle angle) similarity theorem to prove the triangles congruent.

Answer:

Triangle PQR and RST are both right triangles but they do not share the same  side lengths. They also share the same point R, so I would say that they are similar only because they are both right triangles.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Cost function of banner advertisement:

C(n) = 0.30n + 5.00

n = average number of hits per hour

5 = flat rate

From the function, C(n), the cost per hit is the slope value of the function ; which is 0.30

1.) If the cost of pop-up advert will double the cost per hit, the cost function for pop-up advert will be :

D(n) = 2(0.30n) + 5

D(n) = 0.60n + 5.00

B.) This change in cost per hit has resulted in change in slope which is defined as :

[Rise / run = vertical change / horizontal change].

Hence, both vertical and horizontal change has occurred.
