Answer:

3. z = 0

I could only find the answer for number 3. I'm sorry! I hope this helps anyway!

Answer:

It might be very wrong

3. 6z + 12 = 30z + 12

0 = 24z

z = 0

4. 3x +3 +1 +2x = 4x +4+ x

4 +5x = 5x +4

0 = 0

5. - 2b = - 2b +4+3-3

Answer:

Shawna needs a mix of 4 cups of yoghurt and 6 cups of blueberries

Step-by-step explanation:

Here, we want to know the number of cups of yoghurt and smoothies Shawna needs to make;

We have 2 parts yoghurt and 3 parts blueberry, so we can say we have a ratio of 2:3

The total number of cups to be made is 10

So the number of cups of yoghurt will be;

2/(2+3) * 10

= 2/5 * 10 = 4 cups

The number of cups of blueberry would be;

3/5 * 10 = 6 cups

So a mix of 4 cups of yoghurt and 6 cups of blueberries is needed by Shawna

Answer:the bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Step-by-step explanation:

The function has the greater slope and it represent : The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

According to the question

The cost per hour to rent a bicycle and the cost per hour to rent in-line skates are given .

We will conclude which function has the greater slopes

if any function have greater slope than other that implies that  it have greater change in  y  axis in comparison to other

as over here  

y axis = cost

x axis = hours

Therefore,

The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Hence, The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Answer:

12.5%

Step-by-step explanation:

Step 1:

We need to find out the percentage of picking a marble that is red. In total, there are 10 marbles, and there are 5 red. To find the probability of picking a red marble, you need to do:

# of red / total marbles.

There are 5 red marbles and 10 total marbles, so the probability of getting a red marble is 5/10, and you can simplify it to 1/2 (5/10 * 5/5).

Step 2:

Now we can start finding the probability of finding the probability of choosing three red marbles in a row. Since we need to find the probability of choosing red marbles three times, you can multiply 1/2 by itself 3 times (1/2 * 1/2 * 1/2).

1/2 * 1/2 * 1/2 = 1/8

Step 3:

Now we need to convert the fraction into a percentage. You can find the percentage by dividing 1 by 8. You should get 0.125, and you can multiply 0.125 by 100, and your final answer should be 12.5%.

Answer:  -12

Step-by-step explanation:

Input -2 into the function for where you see x and solve to find out what h(-2) is

h(-2) = -4(-2)^2 + 3(-2) +10  

h(-2) = -4(4) -6 + 10

h(-2) = -16 -6 +10

h(-2) = -22 + 10

h(-2) = -12

Answer:

$431.67

Step-by-step explanation:

Let

The one time $50 rebate be for the first month

Cost of insurance per month = x

First month cost of insurance = x-50

Total cost of insurance = $2,540

Total cost of insurance = 1st + 2nd + 3rd + 4th + 5th + 6th

2,540 = x-50 + x + x + x + x + x

2540 + 50 = 6x

2590 = 6x

Divide both sides by 6

x= 2,590 / 6

= 431.67

x= $431,67

The cost of the insurance per month = $431.67

Check:

$431.67 * 6 months

=$2,590.02

Minus one time rebate of $50

= $2,590.02 - $50

= $2,540.02

Approximately

Answer:

12 people are needed to build 12 bikes in 6 hours

Answer:

Step-by-step explanation:

Given the line containing the points.

x | -7. -6. -5. -4

y | 21. 17. 13. 9

The slope of the line is expressed as m = Δy/Δx = y₂-y₁/x₂-x₁

Using the coordinates y (21, 17) and corresponding value of  x(-7, -6)

y₁ = 21, y₂ = 17 x₁ = -7, x₂ = -6

Substituting the values into the formula for calculating the slope, we have;

m = Δy/Δx = 17-21/-6-(-7)

m = -4/-6+7

m = -4/1

m = -4

Hence the slope of the line that contains these points is -4

There are several theorems to prove line relationships in plane geometry.

The proof of parallel lines is done by

To prove that lines are parallel, we make use of the concept of line transversal.

The vertical angle theorem is based on two lines intersecting at a point

The alternate interior angle theorem is used to determine the congruence of angles in a transversal of parallel lines

The converse of corresponding angles postulate, and the converse of same-side interior angles theorem are used to determine if lines are parallel based on the angles on the transversal.

Answer:

∠ D = 48°

Step-by-step explanation:

Since AC ~ BC then Δ ABC is isosceles and the base angles are equal, thus

∠ B = ∠ C = 69°, then

∠ ACB = 180° - (69 + 69)° = 180° - 138° = 42° ( sum of angles in Δ )

∠ DCE = ∠ ACB = 42° ( vertical angles )

∠ D = 180° - (90 + 42)° = 180° - 132° = 48°
