Your next Pre-Algebra test is worth 93 points and contains 38 multiple choice and short answer problems. Each
multiple choice problem is worth two points and each short answer is worth three points. How many of each type of
problem is on the test?

Answers

Answer 1

Answer:

21 of multiple choice and 17 of short answer questions

Step-by-step explanation:

Multiple choice = mShort answer = s

Equations:

m + s = 382m + 3s = 93

Solve for s by eliminating m. Subtract the double of the first equation from the second one:

2m + 3s - 2(m + s) = 93 - 2(38)3s - 2s = 93 - 76s = 17

Find the value of m:

m = 38 - 17 = 21

Answers

Answer:

b. -

Step-by-step explanation:

Note the rules of multiply/dividing negative numbers:

1) A positive number multiplied/divided by a positive number = a positive answer.

2) A positive number multiplied/divided by a negative number (and vice versa) = a negative answer.

3) A negative number multiplied/divided by a negative number = a positive answer.

Note the question.

The first part is multiplying a negative number with a negative number:

(-) * (-) = (+) , based on the rules given above.

Next, multiply the next number. Note that it is also a negative number:

(+) * (-) = (-) , based on the rules given above.

Answers

Answer:

The answer is C. Square root

Step-by-step explanation:

The parent function of given graph is a square root function

The correct answer is an option (c)

What is a function?"It defines a relation between input and output values.""In function, for each input there is exactly one output."What is cube root?

"The function of the form [tex]f(x)=\sqrt[3]{x}[/tex] "

What is reciprocal function?

"This function obtained by finding the inverse of a given function."

What is square root function?

"The function of the form [tex]f(x)=\sqrt{x}[/tex] "

What is an absolute value function?

"The function of the form f(x) = |x| "

For given question,

We have been given the graph of a function.

We need to identify the parent function for the given the graph.

We can observe that the graph increases slowly.

The range of the function is set of all positive values.

We know that the range of square root function is always positive.

If we draw the graph for following functions

i) cube root function

ii) reciprocal function

iii) square root function

iv) absolute value function

Then the parent function of given graph is a square root function

Therefore, the correct answer is an option (c)

Step-by-step explanation:

Basically to find the slope you take the rise over run. How many squares does the line go up, over how many does it go left or right. As you can see in the diagram, it goes up 2 squares and goes left 1 square, giving the slope 2/1, which is 2.

The slope of a horizontal line is straight, which means it goes up 0, so automatically your answer is zero, because dividing anything by 0 is 0.

Rewrite the problem using fewer words. Leave out information that you do not need to solve the problem. Then solve the problem. For a science project, you record the high temperature each day. The high temperature on Day 1 was 6°less than on Day 4 and 4°less than on Day 10. The high temperature on Day 10 was 62°F. What was the high temperature on Day 1?

Answers

Answer:

Each day, you record the high temperature* (you don't necessarily need to say that it is for a science project). On Day 1, it was 4* less than Day 10**. It hit 62* F on Day 10. What was the high temperature on Day 1?

Because we know that on Day 1, the temperature was 4* less than on Day 10, and the high temperature on Day 10 was 62*, the high temperature on Day 1 was therefore 58*. Because 62 - 4 = 58.

Step-by-step explanation:

*You don't necessarily need to say that it was for a science project.

**The information for Day 4 is irrelevant too because we are not given the temperature for Day 4, therefore it does not help us find the answer.

Step-by-step explanation:

y = mx + b

m = [tex]\frac{y_{2}- y_{1} }{x_{2}- x_{1}}[/tex] = [tex]\frac{-9-(-4)}{2-1} = -5[/tex]

y = -5x + b: then plug in a point to find b

Answer:

Step-by-step explanation:

Answer:

Multiply both the numerator and the denominator by the same whole number.

For example;

If you multiply 1/2 by 2/2, this will equal 2/4. You can simplify 2/4 to 1/2.

So to find 1/2 to be equivalent to another fraction, multiply both the numerator and the denominator by the same number to find a fraction that equals 1/2.

X=8 because 39/3 is 13 and 13- 5 is 8 and 5 and 8 add up to make 13 inside the parenthesis.

Answer:

x = 8

Explanation:3(x + 5) = 39Divide Both Sides By 3

3(x + 5) / 3 = 39 / 3

Simplify

x + 5 = 13

Subtract 5 From Both Sides

x + 5 - 5 = 13 - 5

Two pairs of socks and a pair of slippers cost $30. Five pairs of socks and a pair of slippers cost $42. Let u

represent the cost of a pair of socks and let y represent the cost of a pair of slippers.

Identify the system of equations that represents the situation and identify the solution to the system of equation.

Answers

Answer: See explanation

Step-by-step explanation:

The information given in the question can be turned into an equation as:

2u + y = 30 ........ i

5u + y = 42 ........ ii

Subtract i from ii

3u = 12

u = 12/3 = 4

A pair of socks cost $4

Since 2u + y = 30

2(4) + y = 30

8 + y = 30

y = 30 - 8 = 22

A pair of slippers cost $22

Since some natural resources can be grown over and over again, this creates more resources, products to sell, and jobs to fulfill the demand of supplies. As one of our most valuable natural resources, water is useful for supplying jobs for bodies of water, supporting the agriculture industry, and making hydroelectric power. On page 12, it says, As river water rushes through the dams, it makes electricity. Washington state dams create more electricity than almost any other state in the country. This shows that water is a very reliable resource to keep our economy strong.Trees, one of the most important natural resources, can be made into houses, paper, furniture, rubber, and many more goods that are sold to companies around the world and used in our daily lives.Another naturally occurring resource are fossils and bones. Most fossil fuels are non-renewable resources, such as coal, petroleum, and natural gases. Jobs could potentially be created to collect these finite resources. These can be sold and used, but not very helpful towards the environment. Water, trees, and fossil fuels are keeping the Washington economy strong. Water provides hydroelectric power, and supports agriculture. Trees provide materials for many different materials. Last but not least, fossil fuels are still valuable for job creation and power generation.Please tell me what you think!
