In the triangle shown, find x.

Answer:

A -2,-3, B 0,-3  C -1,1

Step-by-step explanation:

The rate of change from 2015 to 2017 is -$250 per year.

Given that,

According to the scenario, computation of the given data are as follows,

Total change = $300 - $800

= -$500

Total years from 2015 to 2017 = 2 years

So rate of change = -$500 [tex]\div[/tex] 2

= - $250

Answer:

x = 8/5 and y = -4/5

The method used was SUSTITUION METHOD

Step-by-step explanation:

x = -2y

2(-2y)-y = 4

-4y-y = 4

-5y = 4

y = -4/5

then

x= -2(-4/5)

x = 8/5

Answer:

[tex]x + 2y= 2[/tex]

Step-by-step explanation:

Given

Points:

[tex]F = (4,9)[/tex]

[tex]G = (1,3)[/tex]

Required

Determine the equation of line that is perpendicular to the given points and that pass through [tex](2,0)[/tex]

First, we need to determine the slope, m of FG

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

Where

[tex]F = (4,9)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]G = (1,3)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]m = \frac{3 - 9}{1 - 4}[/tex]

[tex]m = \frac{- 6}{- 3}[/tex]

[tex]m =2[/tex]

The question says the line is perpendicular to FG.

Next, we determine the slope (m2) of the perpendicular line using:

[tex]m_2 = -\frac{1}{m}[/tex]

[tex]m_2 = -\frac{1}{2}[/tex]

The equation of the line is then calculated as:

[tex]y - y_1 = m_2(x - x_1)[/tex]

Where

[tex]m_2 = -\frac{1}{2}[/tex]

[tex](x_1,y_1) = (2,0)[/tex]

[tex]y - 0 = -\frac{1}{2}(x - 2)[/tex]

[tex]y = -\frac{1}{2}(x - 2)[/tex]

[tex]y = -\frac{1}{2}x + 1[/tex]

Multiply through by 2

[tex]2y = -x + 2[/tex]

Add x to both sides

[tex]x + 2y= -x +x+ 2[/tex]

[tex]x + 2y= 2[/tex]

Hence, the line of the equation is [tex]x + 2y= 2[/tex]

Answer:

The number of green pens sold is 96.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

A shop sells packs of black pens, packs of red pens and packs of green pens. There are:

2 pens in each pack of black pens

5 pens in each pack of red pens

6 pens in each pack of green pens

On Monday, number of packs of black pens sold : number of packs of red pens sold : number of packs of green pens sold = 7:3:4

A total of 212 pens were sold.

Work out the number of green pens sold.

The explanation of the answer is now given as follows:

Since the ratio is given in packs of pens, we have to first convert it to number of pens based on the number of pens in each pack. Therefore, we have:

7:3:4 is converted to (7 * 2) : (3 * 5) : (4 * 6) = 14 : 15 : 24

Based the new ratio, we have:

Weight of contribution of the green pens to the total number of pens sold = 24 / (14 + 15 + 24) = 24 / 53 = 0.452830188679245

The number of green pens sold can now be calculated as follows:

Number of green pens sold = Total pens sold * Weight of contribution of the green pens to the total number of pens sold = 212 * 0.452830188679245 = 96

Therefore, the number of green pens sold is 96.

Answer:

You would need to sell 24 pizzas

Step-by-step explanation

132/44= 3

Take the 3 and times it by 8

3 x 8 = 24

You would need to make 24 pizzas

Each pizza is 5.50$

So an equation for this could be

5.50x P = C

P = Pizza

and C is the cash you earned

Answer:

∠1 = 116

Step-by-step explanation:

Find the inner angle first, the inner angle will be represented with x, also a triangle is 180 degrees, so:

57 + 59 + x = 180

116 + x = 180

subtract 116 from both sides

x = 64

So now u have the inner angle, and a straight line is also 180 degrees, so:

64 + ∠1 = 180

subtract 64 from both sides

∠1 = 116

Answer: The slope is undefined.

Step-by-step explanation:

Using the formula given, find the difference in the y coordinates of the points and divide it by the x coordinates.

(3,6)

(3,-3)  

y coordinates:  6 - (-3) =  9

x coordinates:   3- 3 = 0  

9/0 =  undefined.

Any number being divided by 0  is undefined because you can't divide something by anything.  

Also remember that if a line is vertical through any of the x coordinate, the slope will always be undefined and the equation of line is x = 3

ANSWER:

$18.90

EXPLAINATION:

To solve, the key word here is "marked down". This means that it is going down by 60%. Subtract 100%-60% which is 40%. Now, always remember that 1% = 0.01. SO 40% will be 0.4.

Multiply 47.25x0.4 = answer

18.90 will be the answer

Answer:

$30+m($5 x h)

he will be working for 21 h

Step-by-step explanation:

So, Steve has $30, so you want to add that amount to the amount he earn, which is $105.

$5 times 21 is $105

h = 21

but we still need for m but, we already have m

m = $105

Answer:

W= - 8

-10 + 2 = w

-8 = w

W = -8

Answer:

w = -8

Step-by-step explanation:

1. Add 2 to the -10

2. -10 + 2 = -8

W = -8

Let's solve your inequality step-by-step.

h−(−2)≥10

Step 1: Simplify both sides of the inequality.

h+2≥10

Step 2: Subtract 2 from both sides.

h+2−2≥10−2

h≥8

Answer:

h≥8

(Pls mark brainliest)

The solution to the inequality h  -(-2)  ≥  10  is  h  ≥   8

The given inequality is:

h  -(-2)  ≥  10

Simplify the left hand side

h  +  2  ≥  10

Subtract 2 from both sides of the inequality

h  +  2  -  2  ≥  10  -  2

h    ≥   8

The solution to the inequality h  -(-2)  ≥  10  is  h  ≥   8
