The Taco Hut sells 2 tacos for $2.18, 3 tacos for 3.00, 4 tacos for 3.82, 5 taocs for 4.64. if this patern goes on, how much wound 8 tacos.

Answers

Answer: $7.10

(2,2.18) (3,3) (4,3.82) (5,4.64)

First find the rate of change using y1-y2/x1-x2

3-2.18/ 3-2

=0.82

Next, find the y-intercept or the flat rate

Use the formula y-y1=m(x-x1)

y-3=0.82(x-3)

y-3=0.82x-2.46

y=0.82x+0.54

Next, replace x with 8 for 8 tacos

y=0.82(8)+0.54

y=7.1

Part 1 out of 4
Write an equation in slope-intercept form to represent the number of questions on the test

Answers

Here's our data:

15 questions total

Total number of points: 100

Spelling questions are worth 5 and represented by x

Vocab questions are worth 10 and represented by y

Therefore:

x+y=15

5x + 10y= 100

So:

x+y=15

x= 15-y

5x +10y =100

5(15 -y) +10y =100

75 -5y +10y =100

75 +5y = 100

5y=25

y=5

x +y=15

x+5=15

x=10

There are 10 spelling questions and 5 vocab questions

Sam spent $1.08 to make 18 copies at office max.At that rate how much will he pay to make 40 copies?

Answers

Answer:

$2.40

Step-by-step explanation:

If we know it is $1.08 to make 18 copies. We can do the math to find the rate of 1 copy. This would be by doing 1.08/18=0.06. So, it costs $0.06 to make 1 copy. Now, multiply that by 40 copies 0.06x40=2.40. The cost of 40 copies is $2.40.

I can solve these for you

a:
-2+x=-x+2
+2 +2
x=-x+4
+x +x
2x=4

so the solution to a is x=2

b:

Help fast Please!!!!! What is the vertical distance between
(-3, -2.5) and (-3, 5)?

Answers

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.

I hope that helps, have a great rest of your day! ^ ^
