Answer:

(7, 3)

Step-by-step explanation:

Using the midpoint formula

M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}

X = ax1+bx2/a+b

X = -5(1)+3(11)/1+3

X = -5+33/4

X = 28/4

X = 7

Y = ay1+by2/a+b

Y = 1(12)+3(0)/1+3

Y = 12/4

Y = 3

Hence the coordinate of P is at (7, 3)

Answer:

4 cm

Step-by-step explanation:

A parallelogram area formula= Base x Height.

It already gave you the area so you can work backwards to solve for the base.

So, 20 divided by 5(the height) is 4.

Therefore, you can conclude that the length of the base is 4 cm.

Answer:

y = 8x + 2

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here, m = slope of the line

b = y-intercept

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

By this formula, slope of a line passing through (1, 10) and (0, 2) will be,

m = [tex]\frac{10-2}{1-0}[/tex]

m = 8

Equation of the line will be,

y = 8x + b

Since, this line passes through (0, 2),

2 = 8(0) + b

b = 2

Therefore, equation of the line will be,

y = 8x + 2

y=3x+2

Answer:

40 people came to the Center to hike

Step-by-step explanation:

30 people took classes

22 did bird watching

12 did both

to solve, take 12 and subtract it from each one:

⇒ 30 - 12 = 18

⇒ 22 - 12 = 10

18 people only took classes

10 people only did bird watching

12 people did both

18 + 10 + 12 = 40

The missing terms in the equation  (__ + 7) + (2x - 6) = - 4x + 1 is - 6x.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, An equation (__ + 7) + (2x - 6) = - 4x + 1.

Simplifying the LHS we have,

__ + 7 + 2x - 6.

__ 2x + 1.

Now, The difference between 2x and - 4x is - 6x.

Therefore, The complete equation where LHS = RHS would be,

(- 6x + 7) + (2x - 6) = - 4x = 1.

Answer:

C

Step-by-step explanation:

C will have the least value with -99.

A would be 1/100, which is 0.01, which is small, but larger than -99.

B would be 10/100, which is 0.1, which is larger than A.

C is 1-100, which equals -99.

D is 10-100, which equals -90. -99 is smaller than -90.

Answer:

Step-by-step explanation:

No i dont think I wil

Fred finishes his job 2 days before and makes 10 boxes than Georgiana

each day, the number of boxes Georgiana makes each day are 10 boxes.

The number of boxes Fred plans to make = 160 boxes

Number of boxes Georgiana plans to make = 25% fewer than Fred

Number of boxes Fred makes each day = 10 more than the number of boxes Georgina makes

Number of days before the convention Fred finishes his job = 2 days before the convention

Number of days after the convention Georgina completes her job = 2 days after the convention starts

Let x represent the number of boxes Fred makes per day and let y

represent the number it takes Fred to complete his job, we have the

following equations;

x × y = 160

(x - 10) × (y + 4) = 0.75 × 160 = 120

Which gives;

[tex]\mathbf{(x - 10) \times \left(\dfrac{160}{x} +4 \right)} = 120[/tex]

4·x² + 120·x - 1600 = 120·x

4·x² + 120·x - 120·x = 1600

4·x² = 1600

x = √(1600 ÷ 4) = 20

The number of boxes Fred makes each day, x = 20 boxes

Number of days Fred takes, y = 160 ÷ 20 = 8

Step-by-step explanation:

Answer: 44

Step-by-step explanation:

since the inscribed angle is half of true arc measure, (3x+10)= 2(2x-17).

when you work this out, you get 44 as x.

The value of x from the given figure is 44°. Therefore, option B is the correct answer.

The angle subtended by an arc at the center is twice the angle subtended at the circumference . More simply, the angle at the center is double the angle at the circumference.

From the given figure,

Angle at circumference is (2x-17)° and angle at center is (3x+10)°.

Now, (3x+10)°=2(2x-17)°

3x+10=4x-34

4x-3x=10+34

x=44°

Therefore, option B is the correct answer.
