What is the equation of the line that passes through the point (-8,-6) and
has a slope of 1/4

Answers

Answer:

y = 1/4x -4

Step-by-step explanation:

Since you know that that slope int. equation is y = mx+b, and the m is the slope just plug in the slope in the equation. So it will be y = 1/4x + b.

Then what you will do is solve for b in the equation. So what you do is plug in the x and y value from the coordinate given in the equation, so it will be like this:  -6 = 1/4(-8) +b

                -6 = -2 +b

                -4 = b

                  b = -4

So then you plug back the b value into the equation with slope to wtite the equation. So it would be, y = 1/4x -4

A video rental store charges a $20 membership fee and $2.50 for each video rented.

Write a linear equation to model this situation.

Tell what each variable represents.

Answers

Y=2.5x +20 because x would be the number of times you go, and 20 dollars is the original price

Answer:

2.5x + 20 = y

Step-by-step explanation:

first, assign a variable to each unknown:

since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y

x = number of videos rented

y = total cost

so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.

So, the equation is 2.5x + 20 = y

Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it

Answers

Answer:

Step-by-step explanation:

First use distributive property: a(b + c) = a*b + a*c

3n - 6 = -8(6 + 5n)

3n - 6 = 6 * (-8) + 5n *(-8)

3n - 6 = -48 - 40n

Now add 40n to both sides

3n - 6 + 40n = -48 - 40n + 40n

43n - 6 = -48

Now add 6 to both sides

43n - 6 + 6 = -48 + 6

           43n = -42

               n = -42 /43

Answer:

0.98

Step-by-step explanation:

3n-6=-8(6+5n)

3n-6=-48-40n

3n=-48-40n+6

40n+3n=-42

43n=-42

n=0.98 (I rounded it)

What percent of 120 is 42?
can you show your work, please

Answers

Solution for 42 is what percent of 120:

42:120*100 =

(42*100):120 =

4200:120 = 35

Now we have: 42 is what percent of 120 = 35

Question: 42 is what percent of 120?

Percentage solution with steps:

Step 1: We make the assumption that 120 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x​.

Step 3: From step 1, it follows that $100\%=120$100%=120​.

Step 4: In the same vein, $x\%=42$x%=42​.

Step 5: This gives us a pair of simple equations:

$100\%=120(1)$100%=120(1)​.

$x\%=42(2)$x%=42(2)​.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{120}{42}$
100%
x%​=
120
42​​

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{42}{120}$
x%
100%​=
42
120​​

$\Rightarrow x=35\%$⇒x=35%​

Therefore, $42$42​ is $35\%$35%​ of $120$120​.
It’s 35%

42/120 = 0.35

0.35 x 100 = 35%

Perla buys the star necklace that is originally $49.95 but is currently on sale for 62% off. If she gets an additional 20% off, what is the final price of the necklace?

Answers

Answer:

Step-by-step explanation:

Remark

It's not 82.

You have to take the 62% off and then follow it with 20% from the new price.

Solution

62%

If you get a reduction of 62%, it means that you pay 100% - 62% = 38% of the marked price of $49.95.

38% price =49.95 * 62/100

38% price = 3096.9 / 100

38% price = $30.97

20%  Reduction

20% more means that you pay 100% - 20% = 80%

20% more reduction = 30.97 * 80/100

20% more reduction = 2478/100

20% more reduction = 24.78

Conclusion.

Your final price before taxes is $24.78

Can you answer number 6 please

Answers

Answer:

No, the triangles are not similar.

Step-by-step explanation:

For ΔNOP, since all triangles' angles equal 180°, to find the missing angle you subtract the given angles from 180

180-70=110, 110-58=52       ∠N = 52°

since ΔQRS does not have any angle measures of 58° or 52°, the triangles are not similar becasue similar triangles have congruent angles.

The triangular prism above has been created with two equilateral triangles and three congruent rectangles the height of the triangle is 3.5 inches find the surface area of the triangular prism

Answers

Answer:

108 inches square.

Step-by-step explanation:

Here

base= b= 4 inches

height = h=w=  3.5 inches

and length = l= 9  inches

The surface area is the total area of all the sides of the prism. So the area of the 2 triangles is given by

Area of the 2 Δs= b* h= 4*3.5=  13.5 inches square

Area of the 3 rectangles = l*w(3)= 3( 9*3.5)= 94.5  inches square.

Total area = 13.5 + 94.5 = 108 inches square

This can be found by applying another formula.

Surface area of the triangular prism = bh + ( s1+s2+s3) H

                                                         = 4*3.5 + (9+9+9)3.5

                                                          = 13.5 + 94.5= 108 inches square.

where H is the width of the recatngles which is equal to the height of the triangles.
