help me on question 6, please

Answer:

y = - 1/3x - 1/3

Step-by-step explanation:

Slope: - 1/3

y-intercept: -2 - (- 1/3)(5) = - 2 + 5/3 = - 1/3

Answer:

B'=(9 ,-1)

c'=(0 ,1)

D'=(9 ,-5)

Step-by-step explanation:

When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.

Answer:

  D.  5 units

Step-by-step explanation:

The parallel segments divide the slant segments proportionally:

  7.5/10.5 = x/7

  x = 7(7.5/10.5) = 5 . . . . . multiply by 7

The value of x is 5 units.

_____

If you want to use corresponding sides of similar triangles, you get the same result. ΔIGH ~ ΔIJK

  IJ/IG = IK/IH

  7/(7+10.5) = x/(x+7.5) . . . . substitute shown values

  7(x +7.5) = 17.5x . . . . . . . cross multiply

  7(7.5) = 10.5x . . . . . . . . . subtract 7x

 x = 7(7.5/10.5) = 5 . . . . . divide by the coefficient of x

I got it right on the quiz

Answer:

First we have to find the perimiter of the diagram

3+3+4+2=12

then we multiple by 4 which is 48 since the model is 1/4 the size

48 is the answer D

Hope This Helps!!!

Answer:

48

Step-by-step explanation:

(1/4) in = 1 feet

1 inch = 4 feet

3 in = 3*4 = 12 ft

2 in = 2 *4 = 8

4 in = 4 *4 = 16

Perimeter of actual deck = 12+ 12 + 8 + 16 = 48 ft

Answer:

21

Step-by-step explanation:

Note that you are multiplying the values of A, B, & C together, and then subtracting the value of A from it. Plug in the corresponding numbers to the corresponding variables:

ABC - A

(3 * 4 * 2) - 3

(12 * 2) - 3

(24) - 3 = 21

21 is your answer.

Answer:

17

Step-by-step explanation:

nth term is 2n + 5

so for 6th term n = 6

= 2*6 + 5

= 17

Answer:

89 degrees

Step-by-step explanation:

Answer:

89°

Step-by-step explanation:

The sum of all 3 angles in a triangles equals 180. If you add 50 to 41, you get 91. Then, you subtract 91 from 180, getting 89 degrees. Next, you square 89, add 170, subtract 12, add 3,218, subtract 3376, and find square root.

I've been told I have strange ways of finding the answers to mathematical questions.

What is the product of −2 1/2 and −3 1/3

Step-by-step explanation:

What is the product of −2 1/2 and −3 1/3

Answer:

the value of x is 6 i believe

Step-by-step explanation:

What is value of x? Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. But its value may be determined if we try! A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.

Answer:

24.53 is your answer!

Step-by-step explanation:

add all of the numbers from the correct place values.

Answer:

if your doing scientific notation then 2.7x10^3 would be the only one correct. if its not scientific notation then 27x10^3 would be more because it would be equivilent to 2700<27000

Step-by-step explanation:

Answer: B

Step-by-step explanation:

10 to the third power is 10*10*10

10*10=100

100*10=1000

2.7*1000=2700

Second Statement

10 to the power of 3 is 10*10*10

10*10=100

100*10=1000

27*1000=27,000

B is the answer

Answer:

$3 off which is $27

Step-by-step explanation:

10% of 30 is 3 so you would subtract 30 - 3

and you get $27

Answer:

y=7.5x+25

Step-by-step explanation:

7.5x is the cost per person (average rate of change/slope)

25 is the y-intercept (the amout you start out with

and y is the total cost.

Answer:

[tex]\bold{y = 3x + 2}[/tex]

Step-by-step explanation:

In a linear equation, [tex]y=mx+b[/tex], the "[tex]m[/tex]" is identified as the slope, while the b is where you begin, the coefficient: y-intercept.

Now, with that said, let us look at each option, and see which one matches the linear equation.

Option 1

One over three x = y - 3

[tex]\frac{1}{3}x=y-3[/tex]

As you can see, the [tex]y[/tex] should be in front of the equation. And the [tex]-3[/tex] should be next to [tex]x[/tex].

Option 2

[tex]y = 3x + 2[/tex]

This equation is a  linear equation: the [tex]y[/tex] is in the right place, the coefficient is right next to [tex]x[/tex], and where you begin is at the right place. If you look at this equation, and the linear equation, you will notice they both match.

Option 3

[tex]y = 6\times2[/tex]

The equation does not make sense in terms of linear equations, first off all. There is nothing to show it is a linear equation, except from the [tex]y[/tex]. It is the same thing as just adding two numbers and putting an equal sign and [tex]y[/tex] in front of it, which is not a linear equation.

Option 4

y = two over three x

[tex]y = \frac{2}{3}x[/tex]

There is no coefficient in this equation, therefore, it is not a linear equation.

okay i saw on a video .i see the right won A

Answer:

14 days

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

25n+100=450

Step 2: Subtract 100 from both sides.

25n+100−100=450−100

25n=350

Step 3: Divide both sides by 25.

25n/25 =350/25

n=14

Answer:

Two weeks

Step-by-step explanation:

out of these 450, 100 are a flat, and it's 25 times the numer of days. In an equation form, [tex]450 = 100 + 25d[/tex]. The way you solve the equation, you subtract 100 to both sides, and divide by 25 (you can do it in the order you prefer!)

Answer

3,4,5,6,7 because they are between 2 and 8

Answer:

12600

Step-by-step explanation:

first off, let's get the equation of each line, now, let's notice they're lines, thus we can just use two points from each and the point-slope form to get it, so let's do so, Check the picture below.

[tex](\stackrel{x_1}{-3}~,~\stackrel{y_1}{0})\qquad(\stackrel{x_2}{-6}~,~\stackrel{y_2}{6})\\\\\\% slope = m\stackrel{slope}{m}\implies\cfrac{\stackrel{rise}{\stackrel{y_2}{6}-\stackrel{y1}{0}}}{\underset{run}{\underset{x_2}{-6}-\underset{x_1}{(-3)}}}\implies \cfrac{6}{-6+3}\implies \cfrac{6}{-3}\implies -2[/tex]

[tex]\begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{-2}(x-\stackrel{x_1}{(-3)})\\\\\\y=-2(x+3)\implies \blacktriangleright y = -2x-6 \blacktriangleleft\\\\[-0.35em]\rule{34em}{0.25pt}[/tex]

[tex](\stackrel{x_1}{4}~,~\stackrel{y_1}{-6})\qquad(\stackrel{x_2}{6}~,~\stackrel{y_2}{-9})\\\\\\% slope = m\stackrel{slope}{m}\implies\cfrac{\stackrel{rise}{\stackrel{y_2}{-9}-\stackrel{y1}{(-6)}}}{\underset{run}{\underset{x_2}{6}-\underset{x_1}{4}}}\implies \cfrac{-9+6}{2}\implies \cfrac{-3}{2}[/tex]

[tex]\begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-\stackrel{y_1}{(-6)}=\stackrel{m}{-\cfrac{3}{2}}(x-\stackrel{x_1}{4})\implies y+6=-\cfrac{3}{2}(x-4)\\\\\\y+6=-\cfrac{3x}{2}+6\implies \blacktriangleright y = -\cfrac{3x}{2} \blacktriangleleft[/tex]

now, if we look at the first line, it has a hole when x = -1, however is going upwards to the left otherwise, so we can say the equation includes values to the left of x = -1.

the second equation has a hole when x = 2, so we can say that the equation includes values from x = +2 onwards.

[tex]f(x) = \begin{cases}-2x-6&,~~ x < -1\\[1em]-\cfrac{3x}{2}&,~~x>2\end{cases}[/tex]

Answer:

20

Step-by-step explanation:

16/4=4

4*5=20

16=4/5 (80%) so 20= 5/5 (100%)

Answer: 20

Step-by-step explanation:

80/100 x Y = 16

80Y/100 = 16/1

Cross multiply

80Y = 1600

Divide both sides by 80

Y = 1600/80

Y = 20
