Step-by-step explanation:

Question 1 (answer is C)

6 4

5 2

y=mx+b

4= 6m+b

2=5m +b

by subtracting the two equations

m= 2

4= 6(2)+b

b= 4-12

b= -8

y= 2x- 8

then the answer is C

Question 2

the answer is C

the answer is Cbecause the linear function has a power of (1)

Question 3(B)

m= -2

3 5

y=mx+b

5= 3(-2)+b

5= -6+b

b= 5+6

b= 11

y= -2x +11

the answer is (B)

Answer:

x = 3, y = 1

Step-by-step explanation:

By substitution since y = -2x + 7, substitute that for the 2nd y so

-2x +7 = 3x - 8, so x = 3, then substitute the 3 in any of the equations, so y = -2(3) + 7 is equal to 1

If you use elimination you can subtract the two equations from each other to get rid of the y so

y = -2x + 7

-y = -3x + 8

so 0 = -5x + 15, 5x = 15, x=3

Step-by-step explanation:

f(x) = -9x + 8

f(-2)

______________

When we have a function f(x), x can be plugged in with anything, when plugged, the equation the function f(x) is tied too will also have x replaced with the value.

Therefore, if f(x) equals f(-2), -9(-2) + 8

Multiply :

-9(-2) + 8

18 + 8

Step-by-step explanation:

Answer:

a) It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are: A(-2, -1)

b) We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.

Please check the attached graph.

c) The coordinates of the midpoint of AB:  [tex]\left(-2,\:\frac{3}{2}\right)[/tex]        

Step-by-step explanation:

Part a)

Important Tip:

It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are:

Part b)

We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.

Please check the attached graph.

Part c)

We can determine the coordinates of the midpoint of AB using the formula

[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

In our case, we have:

A(x₁, y₁) = A(-2, -1)

B(x₂, y₂) = B (-2, 4)

so substituting [tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-2,\:4\right)[/tex] in the formula

[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

            [tex]=\left(\frac{-2-2}{2},\:\frac{4-2}{2}\right)[/tex]

Refine

            [tex]=\left(-2,\:\frac{3}{2}\right)[/tex]

Therefore, the coordinates of the midpoint of AB:  [tex]\left(-2,\:\frac{3}{2}\right)[/tex]

Answer: 9.055

Step-by-step explanation:

The number between 9.05 and 9.06 will be 9.055.

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.

Given numbers are 9.05 and 9.06. The number between 9.05 and 9.06 will be 9.055.

The number is also plotted on the number line between the numbers 9.05 and 9.06. The number line graph is attached with the answer below.

Therefore, the number between 9.05 and 9.06 will be 9.055.

Answer:

The correct option is a.

Step-by-step explanation:

It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.

EMI on $1000 is $8.78, so EMI on $1 is

EMI on $1 = 8.78/1000 = 0.00878

EMI on $50150 is

EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32

Therefore the correct option is a.

Answer:

Step-by-step explanation:

The consecutive even integers are (2n-2), (2n), and (2n+2), where n is an integer.

(2n-2) + (2n+2) = 36

4n = 36

n = 9

(2n-2) = 16

(2n) = 18

(2n+2) = 20

Answer:

the area of the shape is 7.14

Step-by-step explanation:

First, find the area of the square:

2 in x 2 in = 4 in

then to find the area of the semi- circles add them together to make a circle

To find the area of the circle, use:

pi x radius^2  

Since the diameter is 2 divide the diameter by 2 to get radius  

3.14 x 1^2 = 3.14

The circle is 3.14 plus 4 ( the square ) = 7.14

Answer:

rate boat = 15 mph

rate current = 5 mph

explanation:

d = r * t

t = d/r

240 / (r_boat + current) = 12       Multiply both sides by r_boat + r_current.

240 = 12(r_boat + current)

240/ (r_boat - current) = 24       Multiply both sides by r_boat - r_current

240 = 24*(r_boat - current)    

Since the distances are the same in both equations, you can equate the right side of each.

12 (r_boat + current) = 24(r_boat - current)     Divide by 12

r_boat + current  = 2 (r_boat - current)             Remove the brackets.

r_boat  + current = 2*r_boat - 2* current          add 2 currents to both sides

r_boat  + 3currents = 2*r_boat                          Subtract r_boat both sides

3 currents = r_boat.

240 = 12*(r_boat + current.                               Divide by 12

20 = r_boat + current                                        Put 3 currents in for r_boat

20 = 3currents + 1 current                                Combine

20 = 4 currents                                                  Divide by 4

5 = current

The rate of the current = 5 miles / hour

3 currents = r_boat

3*5 = rate_boat

15 = rate of the boat
