Answer:

i think its -8

Step-by-step explanation:

Answer:

Please check the attached diagram.

Thus, we conclude that:

In the diagram,

The blue line indicates that the parent function has been shifted 1 unit upward.

Step-by-step explanation:

Let us recall some transformation knowledge.

We know that

if y = f(x), then y = f(x) + b simply means a transformation of (0, b).

In other words, if we add some constant let say 'b' in the output or y-value, the graph simply shifts upward by b units.

Given that

f(x) = x

so

f(x+1) = x+1 means the parent function f(x) = x has been shifted 1 unit upward.

Please check the attached diagram.

Thus, we conclude that:

In the diagram,

The blue line indicates that the parent function has been shifted 1 unit upward.

Answer:

Check box 4 and 5

Step-by-step explanation:

We know there can only be up to 2 solutions for a quadratic equation.

5x^2-2x-9=0 is your equation, make sure to move that 1 to the left

Now we can use the quadratic formula

a=5

b= -2

c= -9

x= −1.15647

x=1.55647

Thus I would select the last 2 boxes. Both of them are solutions.

Answer:

(-4, 5)

Step-by-step explanation:

partitions 1 to 4 means that point will make part of the line where it is 1 part to the other 4 parts. This means there are a total of five parts.

For x, we go from -7 to 8 or 15 units, and we are 1/5 of that distance so 3 units, add that to -7 we get -4.

For y, we go from 8 to -7, or 15 units, and we are 1/5 of that distance so 3 units, subtract that from 8 we get 5.

[tex] \bf {(2x)}^{0} = 1[/tex]

The rule is that any number raised to the power of 0 equals to 1.

So if 2 or 1,000,000 is raised to the power of 0 it equals 1.

But 0 to the power 0 is undefined!

0 to any positive power is 0, so 0 to the power 0 should be 0. But any positive number to the power 0 is 1, so 0 to the power 0 should be 1. We can't have it both ways. Underlying this argument is the same idea as was used in the attempt to define 0 divided by 0.

Answer:

3 AKA B

Step-by-step explanation:

if you look at it 3 is the highest peak

Answer:

6.81s

Step-by-step explanation:

First you must know that the velocity of the body is zero at the maximum height.

v =dy/dx

v= -32x+218

Since v = 0

-32x+218 =0

32x =218

x= 218/32

x = 6.81s

Hence the rocket reaches its maximum height after 6.81s

Answer i got it wrong it was 5.94

Step-by-step explanation:

Answer:

588

Step-by-step explanation:

In a factor tree, I mostly like to look from down to up so that I can track down the non-square number. In a square number, there must be two factors that are exactly the same as each other, and when multiplied gives that square number.

So based on the 5 × 5, 2 × 2, and 7 × 7, we can tell that 25, 4 and 49 are all square numbers. We move up one level. Since the factors of 196 are square numbers, 196 is also a square number since it consists of 2² × 7².

We move another step up. 588 consists of 3 and 196. We know that 196 is a square number, but 3 is a prime number, which means that 3 only has a factor of 3 and itself. Thus, 588 is not a perfect square number since there should be a double factor for 3.

Answer:

Cost of the cleaning, C is the dependent variable

Area of the carpet, a is the independent variable

Step-by-step explanation:

cost of the cleaning is calculated from the area of the carpets

C= the cost of the cleaning a= the area of the carpets.

Cost of the cleaning, C is the dependent variable

Area of the carpet, a is the independent variable

A dependent variable is a variable which depends on other factors to exist. They take their values based on other factors. Their value is changed as a result of a change in independent variable

An independent variable is a variable which does not change as a result of the change in other factors. They take their values irrespective of external factors around them.

The first number is 184

Step-by-step explanation:

Hope this helps u!! :D

Answer:

Please check explanations for answer

Step-by-step explanation:

Let us choose 4 and 6

When we talk of the greatest common factor, we mean the highest number that is a factor of both numbers

The factors of 4 are 1,2,2 and 4

Factors of 6 are 1,2,3 and 6

So as we can see the only common factors to both are 1,2 but the highest here is 2

The least common multiple refers to the smallest number which divides 4 and 6 at the same time without leaving a remainder

Multiples of 4 are 4,8,12 , 16,20 •••••

multiples of 6 are 6,12,18,24

As we can see, the lowest common number to both is 12

RPQ is an isosceles triangle. C is the midpoint of line RQ- Given

RPC=QPC- construction

PC=PC reflective property

RPC= QPC- SAS

Answer:

62 degrees

Step-by-step explanation:

First, it is important to note that all three angles in a triangle add up to be 180 degrees, and if you draw a straight line extending off the side of a triangle, the outside angle and the inside angle are supplementary (they add to be 180 degrees). So,(3x+3)+(2x+4)-180=measure angle F, and 180-(7x-5)=measure angle F according to the rules respectively. Since both of these equations are equal (they both equal the measure of angle F) we can set them equal to each other to find the value of x=> 180-(7x-5)=(3x+3)+(2x+4)-180=> 180-7x-5=3x+3+2x+4-180. Now combine like terms=>175-7x=5x-173. Now, add 7x to both sides and add 173 to both sides to get the variables on one side of the equation=> 175+173-7x+7x=5x+7x-173+173 (the 7x and -7x on the left side and the 173 and -173 on the right side cancel out) =>348=12x. Divide both sides by twelve to find x=> 29=x. Now, plug 29 into what is given for angle FDE=> 2(29)+4=

58+4=

Answer:

Candy = $ 0.5

Soda = $ 4.0

Step-by-step explanation:

x + 2y = 5

x + 4y = 6

2y = 1

y = 1/2

= two candies were added and the price increased by 1 dollar, meaning that the a single candy is 0.5 dollar

1 candy = 0.5

x + 2(0.5) = 5

x + 1 = 5

x = 4

Step-by-step explanation:

Answer:

21

Step-by-step explanation:

Answer:

Ziad is 30 years old.

Marc is 10 years old.

Step-by-step explanation:

We will use m to represent Marc's age this year, and z to represent Ziad's age this year.

This year:

z = 3m

To show their relative ages in ten years time:

z + 10 = 2(m+10)

We can rearrange this to make m the subject.

z + 10 = 2m + 20

z = 2m + 10

We also know that m = 3z. We can substitute this value into our equation.

3m = 2m + 10

m = 10

Use z = 3m to find that z = 30.
