Answer 1

Answer:

The value of a = -12

Step-by-step explanation:

Given the equation

[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]

Determining the value of a

Given the equation

[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]

Apply the exponent rule:   [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]

[tex]\:8^{-55-a}=8^{-43}[/tex]   ∵ [tex]\frac{8^{-55}}{8^a}=8^{-55-a}[/tex]

[tex]-55-a = -43[/tex]

Add 55 to both sides

[tex]-55-a+55=-43+55[/tex]

Simplify

[tex]-a=12[/tex]

Divide both sides by -1

[tex]\frac{-a}{-1}=\frac{12}{-1}[/tex]

Simplify

[tex]a=-12[/tex]

Therefore, the value of a = -12

what is x's value 4x+4y=44 y=2x+2

Answers

Answer: x = 11 + y

Step-by-step explanation: Simplifying

4x + -4y = 44

Solving

4x + -4y = 44

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

4x + -4y + 4y = 44 + 4y

Combine like terms: -4y + 4y = 0

4x + 0 = 44 + 4y

4x = 44 + 4y

Divide each side by '4'.

x = 11 + y

Simplifying

x = 11 + y

Answers

Answer:

Point A: (-3,3)

Point B: (3, -2.5)

Point C: (-4, -4)

point D: (1,0)

Step-by-step explanation:

Answer:

1. Point A (-3, 3)

2. Point B (3, -2.5)

3. Point C (-4, -4)

4. Point D (1, 0)

Explanation:

to identify the coordinates of each point, begin by locating where the point is across from the x axis and y axis.

These coordinates are in the form (x, y)

where x is the horizontal [left and right] orientation or location in respect to the x axis, and y is the vertical [up and down] orientation or location in respect to the y axis.

Point A is 3 units to the left and 3 units up from the origin [(0, 0)] so the coordinate of this point is (-3, 3).

Point B is 3 units to the right and 2.5 units down from the origin [(0, 0)] so the coordinate of this point is (3, -2.5).

Point C is 4 units to the left and 4 units down from the origin [(0, 0)] so the coordinate of this point is (-4, -4).

Point D is 1 unit to the right and 0 units down from the origin [(0, 0)] so the coordinate of this point is (1, 0).

what is my average grade if i have seven 100's and one 0

Answers

Answer:

90/100 or 81.8%

Step-by-step explanation:

w = 0,1 , then your grade will be 81

It depends upon how many total points are available and what the zero was out of possible points. If you have a 90/100 and a 0/100, that gives you a 45%, which is failing. If you have 90% of 1000 points and get a 0/100, that will land you with an 81.8%.

Step-by-step explanation:

hey there,

< When you have these kinds of problems:

[tex]\frac{2}{6} = \frac{x}{12}[/tex]

There's a really easy way to solve it. Multiply the two that are across from each other. That means 2 x 12. It couldn't be 6 x [tex]x[/tex] because this one has x in it so it won't work. So you multiply them: 2 x 12 = 24. Then you divide that number by the last number available. The last number that hasn't been used yet is "6" (we have used 2 and 12). So we divide 24/6.

24/6 = 4

x = 4 >

9. One number is 7 more than twice another number. The sum of the numbers is 22. What is one of the numbers?
O-5
O 10
07
O 17

Answers

Step-by-step explanation:

Hey there!

According to the question,

Let the unknown number be x (smaller) another number be y (greater) respectively.

1st condition: One number is 7 more than twice of another number.

(i.e y = 2x+7)....... (i)

2nd condition: The sum is 22.

(i.e X+y= 22)……(ii)

From equation (ii).

x+ y= 22

x= 22-y

Putting the value of X in eqaution (I)

y = 2(22-y)+ 7

y = 44 - 2y +7

3y = 44+7

y = 51/3

Therefore, y= 17.

Now, Putting the value of y in eqaution (ii)

X = 22-y

x = 22-17

Therefore, x= 5.

Therefore, one number is 17. (Option D).

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Kendra is buying an outfit that is on sale for 20% off.

The original price of the outfit is $109.

The discount,

= 20% of 109

= 20 x 109 / 100

= 21.8

The sales price,

= 109 - 21.8

= 87.2

Therefore, the price is $87.2.
