Isabella and her cousin Rodrigo have the same birthday but isabella is 15 years older than Rodrigo the equation y= x + 15 represents isabella's age y, when Rodrigo is x years old what is the answer?.

Answers

Answer:

The answer is below

Step-by-step explanation:

Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship

Solution:

Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:

y = x + 15

You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.

Rodrigo:     10         20            30

Isabella:      25        35           45

When x = 10:   y = x + 15 = 10 + 15 = 25

When x = 20:   y = x + 15 = 20 + 15 = 35

When x = 30:   y = x + 15 = 30 + 15 = 45

What does the quadratic function
f(x) = x2 - 6x + 8 look like when it is
rewritten in the form f(x) = a(x − p)2 +q?

Answers

Answer:

f(x) = (x -3)^2 - 1

Step-by-step explanation:

f(x) = x^2 - 6x + 8

a = 1, b = -6 and c = 8

So we are finding half of the b equation (ignore the negative sign)

Half of 6 is 3, so we are going to square 3 (3^2 = 9) and add 9 to the left side and subtract 9 to the right side

(x) = (x^2 - 6x + 9) + (8 - 9)

You can tell the polynomial is a perfect square, so we will have to factor it using the perfect square method

(x^2 - 6x + 9)

square toot of x^2 is x and square root of 9 is 3 and the operation sign after the a number is a minus sign

(x -3)^2

Don't forget the rest of the equation from before

(x -3)^2 + (8 - 9)

(x -3)^2 - 1

So the equation is f(x) = (x -3)^2 - 1

P=-30h+74 The variable h represents the number of hours he has spent reading, the variable p represents the number of pages left to read. How many hours of reading will Ethan have to do in order to have 14 pages left to read?

Answers

Answer: Ethan will have to spend 2 hours reading if 14 pages are left to read

Step-by-step explanation:

Given the equation

P=-30h+74

where p =number of pages left to read and

h= the number of hours he has spent reading

Therefore , if Ethan has 14 pages left to read, then the number of hours Ethan will have to read will be

P=-30h+74

14= -30h + 74

30h= 74-14

30h= 60

h = 60/30

h =2 hours

Ethan will have to spend 2 hours reading if 14 pages are left to read

Use the Distributive Property to solve the equation.
- 8(x + 7) = 16
Apply the Distributive Property and simplify.
- 8(x + 7) = 16
- 8x + = 16

Answers

Answer:

x= - 9

Step-by-step explanation:

- 8(x +7) = 16-8x - 56 = 16 -8x = 16 + 56-8x = 72x = 72 ÷ (-8) x = -9

Hey there!

Use the Distributive Property and simplify:

-8(x+7)=16

-8x-56=16

Notice we write -8 right next to x.

Add 56 to both sides:

-8x=16+56

-8x=72

Divide both sides by -8:

x=-9

Hope everything is clear.

Which expressions are equivalent to this exponential expression?

Answers

remember that when the exponents look like this (5^2)^-3, you multiply the exponents together

when it looks like this:
5^3 x 5^2 you add the exponents
so my example would equal 5^5

also remember that you can’t have negative exponents

To solve your problem:
1. multiply the exponents here: (5^2)^-3

2. add the exponents in the next step when you multiply by the 5^4

3. now, you should get a negative exponent on the top, and you already have one on the bottom. to get rid of these negative exponents, move the one in the denominator to the numerator and vice versa

so when you move the 5^-4 in the denominator to the numerator, it becomes 5^4

4. now, you simplify. you can either subtract the exponents and do it that way, or you can solve the exponents and then divide. either way will work, although the first is easier

Anais bought 4 1/2 yards of ribbon. She had 3 feet 8 inches of ribbon left after trimming some curtains. How many inches of ribbon did anais use to trim the curtains

Answers

Answer:

First convert all numbers into inches since that is the answer being solved for.

1 yard =36 inches

4.5 x 36 = 1,620 inches

1 foot = 12 inches

3 x 12 = 36 inches

36 + 8 = 44 inches

Now take 1,620 inches (starting ribbon measure) and subtract 44 inches (what was left over) to get the inches used to trim curtains.

1,620 inches - 44inches =

1,576 inches were used to trim the curtains.

Margo added three multi-digit decimal numbers. The first number was 5.19. The second number was 10 times the first number. The third number was 10 times the second number. What was the sum?

Answers

Answer: 576.09

Step-by-step explanation:

First number = 5.19.

The second number was 10 times the first number which will be:

= 5.19 × 10

= 51.9

The third number was 10 times the second number. Thus will be:

= 51.9 × 10

= 519

The sum of the numbers will be:

= 1st number + 2nd number + 3rd number

= 5.19 + 51.9 + 519

= 576.09

How far will he travel if the rear wheel makes 1200 revolutions on the road? For all the years I knew my grandma, she could barely see. Grandma was legally blind, and yet she knew, by feel, the location of every dish in her kitchen and every work of literature on the bookcase in the living room. I remember especially the bird-like way she peered at things. I'd bring her a copy of my latest school picture, and she'd hold the photo an inch or two from her face, tilt her head to one side, and inspect it before saying, "Very pretty." I used to think she was just being polite, that she really couldn't see me in the picture. But then she'd add, "That pin you're wearing was your mother's." How did she see that little blur on my jacket? The things she could see never failed to amaze me. Watching television with Grandma, I never failed to learn something. Usually it was the complicated plot twist of one of her favorite soap operasThe Guiding Light or As the World Turns. We grandkids would curl up on the big couch while Grandma pulled up a footstool and planted herself right next to the TV, elbows on her knees, to watch the screen. At the commercial break, she'd explain who was marrying whom and who was in the hospital and who had recently come back from the dead. She seemed to have no trouble identifying the characters whom she could barely see. Whether or not she could bring them into sharp focus, they were as real to her as her giggling grandkids. For a treat, we'd sometimes pile into our grandparent's black car for a drive around town: my grandfather at the wheel, my long-legged older brother in the front seat, and Grandma sandwiched between me and my little brother in the backbut sitting so far forward she was practically in the front. I'd imagined all she could see was a blur of images rushing past, yet she could always tell when Grandpa had missed a turn or forgotten to turn on his headlights. Returning home, Grandma would wave at the boy who mowed their lawn and point out the new fruit on the plum tree in their yard.
