Answer 1

Answer:

1: 45

2: 32

3: 35

4: 32

Step-by-step explanation:

when finding the area of a trapezium you can also just split the rectangle and triangle to have 2 different areas then combine to have the same area. but also this would be more difficult if you needed to separate the trapezium into more than 3 shapes.

so if there is like a trapezoid that you split and there is a rectangle and 2 triangles it is harder than doing the formula.

so use the formula sometimes too if it is easier.

Answer 2

Answer:

1 would be 45, 2 would be 32, 3 would be 35, 4 would be 32

Solve y=f(x) for x. Then find the input when the output is −3. f(x)=−7x−2 x= The input is when the output is −3.

Answers

Answer:

The input is 1/7

Step-by-step explanation:

If y =f(x)

Given that f(x) = -7x -2, then y = -7x-2

x is the input

y is the output

Given the output y = -3, we are to find the input value x

Recall that y = -7x-2

On substituting the value of y into the equation

-3 = -7x - 2

-7x = -3+2

-7x = -1

x = -1/-7

x = 1/7

Hence the input is 1/7

put them from least to greatest ​

Answers

Answer: -7/10, -0.35, 1/5, 0.95

Step-by-step explanation:

-7/10 =  -.7

1/5 = 0.2

Answer:

From least to greatest, the correct order is [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.

Step-by-step explanation:

Since all negative numbers are smaller than positive, you immediately know that [tex]-\frac{7}{10}[/tex] and -0.35 are smaller than [tex]\frac{1}{5}[/tex] and 0.95. The greater the absolute value of a negative number is, the smaller that number is. Because [tex]-\frac{7}{10}[/tex] is -0.7, which has a greater absolute value than -0.35, this means [tex]-\frac{7}{10}[/tex] is the smallest number, and -0.35 is the second smallest number. Since [tex]\frac{1}{5}[/tex] is 0.2 which is smaller than 0.95, the correct order from least to greatest would be [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.

A carpet store advertises 16 yards of carpeting for $300, which includes the $60 installation fee in the price. Let x represents the cost of one square yard of carpet. What is the price for one square yard of carpet?

Answers

Answer:one yard costs $15 (x=15)

Step-by-step explanation:

300-60=240. So, 16 yards=$240

16x=240

240/16=15

X=15 (one yard costs $15)

The price for  one square yard of carpet is $15.

Given that,

A carpet store advertises 16 yards of carpeting for $300, which includes the $60 installation fee in the price. Let x represents the cost of one square yard of carpet.

Answers

Step-by-step explanation:

C) 5x + 13x = 180°

Because, the angles in the diagram add up to 180° because it's a straight angle

Answer:

-3/4

Step-by-step explanation:

You could identify two points and used the slope formula given two points.

OR

You can just count from one point to another.

First step: Identify two points where the line crosses nicely.

I see one at the y-intercept (0,1) and another at (4,-2). So starting at the y-intercept, how much do we need to travel down to get to (4,-2).  Hopefully you say down 3, so the rise is -3.  Now how much to the right after traveling down 3 from (0,1) to we need to travel to get to (4,-2) .  Count the spaces...4 units right so the run is 4.

The slope is -3/4

A triangle has angle measures of 47 degrees and 92 degrees. What is the measure of the third angle?

Answers

Answer:

The missing angle is 41 degrees

Step-by-step explanation:

First of all, a triangle is measured at 180 degrees in total

To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.

47+92=139 degrees

Next just subtract 139 from 180 to get your answer.

180-139=41 degrees

The answer is 41 degrees

How many solutions does this system of equations have?

y = -1/3x + 7
y = -2x^3 + 5x^2 + x - 2

Answers

Answer:

its one solution

Step-by-step explanation:

This system of equations have a unique solution.

What is a system of equation?

A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.

For the given situation,

The system of equations are

y = -1/3x + 7  ------- (1)

y = -2x^3 + 5x^2 + x - 2 ------- (2)

Equation 1 is a linear equation and equation 2 is a polynomial equation.

So graph these two equations to find the solution.

The graph below shows the plotting of these two equations and

solution of these equations.

From the graph, it is clearly seen that this system of equation has only one solution.

Hence we can conclude that this system of equations have a unique solution.
