Step-by-step explanation:

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:

5x - 9 = 30

Answer:

3397.10 Km

Step-by-step explanation:

STEP1: Equation at the end of step 1

(2x • (5x - 2)) + (2x + 1) • (8 - 5x)

STEP2: Equation at the end of step 2

2x • (5x - 2) + (2x + 1) • (8 - 5x)

..............................................................................

Final result :

7x + 8

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:

6.40

Step-by-step explanation:

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

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:

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:

A. f(-2)=3-6(-2)

-2f =3-(-12)

-2f=3+12

=15

divide both sides by 2

f=15/2

B. f(0)=3-6(0)

f=3

C.f(4)=3-6(4)

4f=3-24

f=21/4

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.

Step-by-step explanation:

thanks though :)

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]

Slope = change in y / change in x

Slope = (1 - 3) / 6 - -2)

Slope = -2/8

Simplify for final answer:

Slope = -1/4

Answer:

Step-by-step explanation:

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.

Answer:

gracey

Step-by-step explanation:

find the equation of both graphs:

for gracey, she increases by 4 pounds every week, so her slope is 4, she starts out at 1 lb so b=1, so her graph is y=4x+1

for luna, she increases by 3 pounds every week, so her slop is 4 and she starts out at 2 lbs so b=2, her graph is y=3x+2.

plug in 5 for x in both equations to find out which y-value is greater, for gracey, y=21, for luna, y=17. 21>17 so gracey will weigh more at 5 weeks

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.
