Answer:

square rt  of 97 = 9.84886

Step-by-step explanation:

Answer:

y = -2/3 + 3

Step-by-step explanation:

y2 - y1 / x2 - x1

-3 - 1 / 9 - 3

-4 / 6

-2/3

y = -2/3x + b

1 = -2/3(3) + b

1 = -2 + b

3 = b

y = -2/3 + 3

Answer:√(6/5) and √(9/7) and √(7/5)

Step-by-step explanation:

1/4 = 0.25

5/4 = 1.25

√(6/5)=1.095445...

√(9/7)=1.1338934...

√(7/5)=1.1832159...

Thus, any non-perfect square radicals will be irrational numbers.

Hope this helps!! :)

Answer:

B

Step-by-step explanation:

Moving it to the right one unit and down one unit, you would have the answer be (x + 1, y-1) because moving it to the right is moving it in the direction of the positive numbers and moving it down is moving it in the direction of the negative numbers.

im not 100% on it tho

Step-by-step explanation:

Answer:

84$

Step-by-step explanation:

It says it costs $3 per visit and Ella went 18 times

So we can describe that as x represents the times she has visited, x=18, so 3(18)

now we just add $30 dollars since she only went in one month and $30 is the fee per month so that would be (3*18=) 54+30

which would then give you $84 dollars!

hope it helps!!

C.) $84

Step-by-step explanation:

Answer:

[tex]2x^2+x+7y[/tex]

Step-by-step explanation:

We are given the equation [tex]2(x^2+3y)+x+y[/tex] and are asked to simplify it.

To do so, we need to first get rid of the parenthesis, since x² and 3y aren't like terms, it isn't solvable unless we try another way, which is the distributive property.

2 is next to the parenthesis, in the distributive property, we would multiply the number outside of the parenthesis with all the numbers inside the parenthesis. Therefore :

[tex](2*x^2) + (2*3y) + x +y[/tex]

[tex]2x^2 +6y+x+y[/tex]

Now that we have like terms, we can add them together :

[tex]2x^2 + 6y+x+y[/tex]

[tex]2x^2 + x+7y[/tex]

Answer:

Hello! Your answer would be, 2[tex]x^{2}[/tex] + [tex]x[/tex] [tex]7y[/tex]

Answer:

b = 12

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

b² + 5² = 13²

b² + 25 = 169 ( subtract 25 from both sides )

b² = 144 ( take the square root of both sides )

b = [tex]\sqrt{144}[/tex] = 12

Answer:

The temperature rised by 10 degrees F.

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

1)

7(3 + 5) = 21 + 35.

7 * 3 = 21 to fill the first square, 7 * 5 = 35 to fill the second square.

2)

15 - 10 = x(3 - 2)

Subtract inside parenthesis.

15 - 10 = x(1)

Cancel the 1.

15 - 10 = x

Subtract.

x = 5.

Proof:

15 - 10 = 5(3 - 2)

15 - 10 = 5(1)

15 - 10 = 5

5 = 5.

Answer:

16 feet

Step-by-step explanation:

Area of a Triangle: (Base*Height)/2.

Therefore, Base:(2A)/Height =(2*24)/2=16

Step-by-step explanation:

angle on a straight line is 180, thus , the angle on the line inside the triangle is

180 - 96 = 84

and since the sum of the angles in a triangle is 180 ,

the angle 1 is ..

180 - 29 - 84 = 67 degrees ,

therefore the answer is D
