Answer:

33.5 units²

Step-by-step explanation:

We can see this figure as 2 shapes: a square and a triangle. The square measures 4 x 4, and it's area is 16. That leaves the triangle, which has half the area of a quadrilateral that measures 5 x 7. The area of the quadrilateral is 35, and the triangle has an area of 17.5, which is half of that. Adding them together, we get 33.5.

Answer:

33.5 unit²

it's a mixture of triangle and square.

draw a imaginary straight line across the figure from that line which has length of 3 units and now you can see the triangle and the square. Use the formula to find area of triangle and area of square and the sum of their area will be the area of this whole figure i.e 35.5 unit²

y = 3/4x - 4.5

Where the line crosses the y-axis is how I got the -4.5

Slope is rise over run, so up 3 and right 4

Answer:

A. The blue line represents the equation 2x-3y=6, and the solution to the system of equations is (–6, –2).

Step-by-step explanation:

Here we have the system:

2x - 3y = -6

y = -(1/3)*x - 4

First, remember that if the slope is negative, then the equation is decreasing.

So, for the second equation, as x increases, y decreases, then the line of the second equation is the red one (because the red one decreases).

So the blue one represents the equation 2x - 3y = -6

Also remember that the solution of a system of equations is the point where the graphs of the equations intersect, here we can see that the intersection happens at the point (-6, - 2)

This means that the solution of the system is  (-6, - 2)

From this, we can see that the correct option is:

A. The blue line represents the equation 2x-3y=6, and the solution to the system of equations is (–6, –2).

A: The blue line represents the equation 2x-3y=6, and the solution to the system of equations is (–6, –2).

Answer:

Step-by-step explanation:

Answer:

[tex]x = \frac{ 16 - 4y}{12}[/tex]

Step-by-step explanation:

12x + 4y = 16

12x + 4y - 4y = 16 - 4y

12x = 16 - 4y

[tex]\frac{12x}{12} = \frac{ 16 - 4y}{12}[/tex]

Answer:

x int (18/5,0)

y int (0.-2)

Step-by-step explanation:

by substitution

Answer:

x-intercept: (3.6, 0)

y-intercept: (0, -2)

Step-by-step explanation:

The x and y intercepts of a line can be found by substituting y= 0 and x= 0 into the equation of the line respectively. The y-intercept is the point at which the line cuts through the y-axis, while the x-intercept is the point at which the line cuts through the x-axis.

-5x +9y= -18

When x= 0,

-5(0) +9y= -18

9y= -18

Dividing both sides by 9:

y= -18 ÷9

y= -2

Thus, the y-intercept occurs at (0, -2).

When y= 0,

-5x +9(0)= -18

-5x= -18

Divide both sides by -5:

x= -18 ÷(-5)

x= 3.6

Thus, the x-intercept occurs at (3.6, 0).

Answer:

second option is the answer

obtuse angle means the angle is larger than 90 degrees

Answer:

The coordinates of the P' point are (-17.3,-10).

Step-by-step explanation:

We can use the components of the vector from 0 to P point. We know that the diameter is 40 meters, so the magnitude of the vector will be 20 m.

Now, the angle from the negative x-direction to the vector is 210°-180° = 30°.

The x-component of the vector will be:

[tex]V_{x}=-Vcos(30)[/tex]

[tex]V_{x}=-20cos(30)=-17.32\: m[/tex]

It is negative because the component is in the negative x-direction.

The y-component of the vector will be:

[tex]V_{y}=-Vsin(30)[/tex]

[tex]V_{y}=-20sin(30)=-10\: m[/tex]

It is negative too because the component is in the negative y-direction.

Therefore, the coordinates of the P' point are P'(-17.3,-10)

Answer:

-70

Step-by-step explanation:

As shown in the picture, you can use the formula:

1st term + common difference(desired term -1)

From what is given, we can see that the first term is -2. We are looking for the 18th term, so 18 is our desired term. Lastly, to find the common difference, we can subtract a the term before a certain term from it:

common difference = -6 - (-2) = -4

Now, we can substitute what we have:

-2 + (-4)(18 - 1)

-2 - 4(17)

-2 - 68

-70

Hello! answer: 30

Step-by-step explanation:

13 × 13 = 169

5 × 5 = 25

169 - 25 = 144

12 × 12 = 144 therefore 12 is the missing leg

so we will use this to find the area so...

12 × 5 = 60 60 ÷ 2 = 30 therefore the answer is 30 hope that helps!

Why? Because they are mirrors of each other. In other words, one table has its x and y row swapped compared to the other table.

The input x = -120 leads to the output y = 627 in table C. Then in table D, we have the input x = 627 to go the output y = -120. Refer to the first column of each table mentioned. The same applies for the other columns as well. The inverse table undoes everything the original table does.

The tables that could be used to verify inverse functions are tables C and D

The inverse of a function are the opposites of the function

From the list of options, we can see that:

The x values of table C are the y values of table D

Also, the x values of table D are the y values of table C

This means that tables C and D are inverse functions

Hence, the tables that could be used to verify inverse functions are tables C and D

C. y = 3x - 4

Step-by-step explanation:

Given coordinates:

(2, 2), (3, 5), (5, 11), (7, 17)

The equation of any straight line is

y = mx + c

Where

m = Gradient

c = Constant

Gradient = y2 - y1/x2 - x1

Substitute any two values of y with the respective values of x.

Gradient = 17 - 2/7 - 2

= 15/5

= 3

Substitute the gradient into the general formula.

y = 3x + c

Substitute any value of the coordinate to the equation

2 = 3(2) + c

2 = 6 + c

c = -4

From y = mx + c,

substitute the values of m, the gradient, and c, the constant.

y = (3)x + (-4)

y = 3x - 4

Answer:

[tex]2x + y = 11 - - - (a) \\ 4x - y = 25 - - - (b) \\ (a) + (b) : \\ 6x + 0y = 36 \\ 6x = 36 \\ x = 6[/tex]

Answer:

y=2x-3

Step-by-step explanation:

first, you have to get the y by itself (isolate the y). you do this by subtracting 4x from both sides.

4x-2y=6

-2y=-4x+6

next, you have to divide both side by -2 to isolate the y further and get this into slope-intercept form:

-2y=-4x+6

y=2x-3
