Answer:

y = -63

Step-by-step explanation:

y - 15 = -78

Add 15 on both sides to get y alone:

y - 15 + 15 = -78 + 15

y = -63

The image below shows two parallel lines cut by a transversal. What is the value of A

rewona [7]

Answer

59°

Explanation

There are 2 parallel line and one transverse.

Angles in a straight line add up to 180°

∴ 180 - (2a + 3) = 180 - 2a -3

= 177 - 2a

The angle (177 - 2a) corresponds to angle a in the diagram. The two corresponding angles are equal.

∴ 177 - 2a = a

177 = a + 2a

3a = 177

a = 177/3

= 59°

Given f(x)=3^(x-2) and g(x)=f(3x)+4, write the function rule for function g and describe the types of transformations that occur

klio [65]

Answer with Step-by-step explanation:

We are given that

$f(x)=3^{x-2}$

$g(x)=f(3x)+4$

We have to write the rule for function g and describe the transformation between f and g.

Compress the function by scale factor 3 and the translation rule is given by

$(x,y)\rightarrow (3x,y)$

Then, we get $h(x)=f(3x)=3^{3x-2}$

Now, shift the y coordinate 4 units above the origin.

Then, the translation rule is given by

$(x,y)\rightarrow (x,y+4)$

Then , we get

$g(x)=3^{3x-2}+4$

Solve using completing the square x^2 – 8x + 16 = 25

lisov135 [29]

First we need to factor the left side. Since it is a perfect square (as is the process with completing the square, we know we can take half of the middle number along with x to be in the two parenthesis.

(x - 4)(x - 4) = 25

Now we simplify to show it as a square.

(x - 4)^2 = 25

Next we take the square root of both sides

x - 4 = +/- 5

Note that we have plus or minus 5. This is because either square would give us positive 25. Now we add 4 to both sides

x = 4 +/- 5

4 + 5 = 9

4 - 5 = -1

An advertiser that uses ad scheduling has a custom bid adjustment for 9pm- 12am on weeknights. The normal bid is USD$0.40 and th

nika2105 [10]

Answer:

The answer is option D: the advertiser is bidding $0.70 between 9 pm-12 am on weeknights.

Step-by-step explanation:

The normal bid is $0.40 and the bid multiplier is 75%.

This amount becomes:

$0.40+(0.75\times0.40)$

= $0.70 (OPTION D)

So, the advertiser is bidding $0.70 between 9 pm-12 am on weeknights.
