Answer:

h(-2) = 13

h(5) = -1

Step-by-step explanation:

Given the function

h(x) = -2x + 9

Evaluating at x = -22

substitute x = -2

h(-2) = -2(-2) + 9

h(-2) = 4 + 9

h(-2) = 13

Therefore,

Evaluating at x = 5

Given the function

h(x) = -2x + 9

substitute x = 5

h(5) = -2(5) + 9

h(5) = -10 + 9

h(5) = -1

Therefore,

Answer:

[tex]\frac{6}{5}[/tex]

Step-by-step explanation:

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~

(3, 3)

( - 2, - 3)

m = [tex]\frac{-3-3}{-2-3}[/tex] = [tex]\frac{6}{5}[/tex]

Answer:

h

Step-by-step explanation:

Answer:

try = (-10/11)x - (49/11)

Answer:

Lin 1.454 h

Noah 1.54h

Step-by-step explanation:

From the above, we were given that;

Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour

Speed of Lin

V = [(2 3/4)/(2/5)] mph

V = [(11/4)/(2/5)] mph

V = 6.875mph

Speed of Noah

V = [(8 2/3)/(4/3)] mph

V = [26/3)/(4/3))] mph

V = 6.5mph

The time taken by Lin to cover 10 miles

t = 10/6.875

t = 1.454h

The time taken by Noah to cover 10 miles

t = 10/6.5

t = 1.54h

A= pi r^2

A= pi 4^2

A= pi16

A= 50.265

Step-by-step explanation:

Answer:

266pi

Step-by-step explanation:

SA = 2*pi*r^2 + 2pi*r*h

= 2pi*r(r+h)

r = 7 and h = 12

2*pi*7(7+12) = 14pi*19=266pi

Answer:

TSA = 2 pi r (r+h)

Undefined

Step-by-step explanation:

The graph shows a vertical line. All vertical lines have a undefined slope.

This is because that while using the slope formula you will end of with the denominator being 0. You cannot divide by zero.

Answer:

Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0

Step-by-step explanation:

We need to solve the expression: [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]

Solving the expression:

We will use simple maths rules to solve the expression

[tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]

Subtracting 1/2 on both sides and simplify

[tex]x+\frac{1}{2}-x-\frac{1}{2}=\frac{1}{2}-\frac{1}{2}\\x-x=0\\0=0[/tex]

Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0

So, the expression is true for all values of x. there will be infinite solutions to the system.

Answer:

A?

Step-by-step explanation:

A is the only one that makes sense, becaues 150% of 500 is 750.

150/100 = 150%

5/5, I believe, just represents the 5 in 500.

102 beats per 2 minutes then 51 beats per minute.

A division is a process of splitting a specific amount into equal parts.

It is given that,

102 beats per 2 minutes

We need to calculate how many beats per minute.

To do this we just have to divide One hundred two by two

102/2

Fifty one beats.

51 beats per minute

Hence 51 beats per minute.

Answer:

3 3/4

Step-by-step explanation:

3/4 * 1/5

First you would turn 1/5 into a reciprocal

Now your equation would be 3/4 *5/1

Now you multiply 3/4 * 5/1

15/4

Now find 15/4 as a mixed number

15/4 as a mixed number would be 3 3/4

Therefore there are 3 3/4 1/2 cup servings in a 3/4 cup of ice

Answer: The complex conjugate has a very special property. Consider what happens when we multiply a complex number by its complex conjugate. We find that the answer is a purely real number  it has no imaginary part. This always happens when a complex number is multiplied by its conjugate the result is real number.

Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers

Step-by-step explanation: Every complex number has a complex conjugate. The complex conjugate of a + bi is a - bi. For example, the conjugate of 3 + 15i is 3 - 15i, and the conjugate of 5 - 6i is 5 + 6i.
