Explain. (Example 3)

Answers

Answer:

The growth rate of Plant A is not proportional

because the line is not straight.

The growth rate of Plant B is proportional

because when the data is graphed on the

coordinate plane, the line formed is a straight

line that passes through the origin.

Write an equation of the line that passes through (1, 2) and is perpendicular to the line y=13x+4.

Answers

Answer:

Step-by-step explanation:

y=-1/13x   since it is perpendicular flip it and make it negative

Answer:

y = -1/13x + 27/13

Step-by-step explanation:

A perpendicular line will have the opposite reciprocal and sign.

So the perpendicular line slope to y = 13x + 4 would be -1/13

NOW PLUG IN (1, 2) TO GET THE Y- INTERCEPT

2 = -1/13(1) + b (b represents the y- intercept)

2 = -1/13 + b (add 1/13 to both sides)

y = -1/13x + 27/13 is the perpendicular line.

Answer:

Option 1

Similar triangles have proportional sides.

This means that the sides of ΔABC must have the same ratio to the sides of ΔSTR, ΔLKJ, or ΔDEF.

The base angle of ΔABC is 6 and therefore the base angle of the similar triangle should be divisible by 6. This leaves ΔSTR out

Continue the process with the other sides:

side BC is 4 units meaning the corresponding side of either ΔDEF or ΔLJK with have to be divisible by 4. in JKL the corresponding side KL is 9 units and not divisible by 4. Therefore, DEF is the correct answer since its corresponding sides are proportional

Step-by-step explanation:

A cell phone provider will allow you to buy a phone over time. They require a $50 initial payment and then charge $25 per month. If this situation were represented by a function, what would be the slope?

Answers

Answer:

25

Step-by-step explanation:

Given that:

Initial payment done for buying the phone = $50

Charges per month for the phone = $25 per month

To find:

The equation to represent the situation and its slope.

Solution:

First of all, let us assume that [tex]m[/tex] represents the number of months for which monthly is to be made.

Charges paid for one month = $25

Charges paid for [tex]m[/tex] months =  $25[tex]m[/tex]

Total cost of the phone = Initial payment + Charges paid for [tex]m[/tex] months

[tex]C = 25m + 50[/tex]

It is a linear equation between two variables [tex]C[/tex] and [tex]m[/tex].

This equation can be compared with slope intercept form of a line.

Slope intercept form of a line is represented by:

[tex]y=Mx+c[/tex]

[tex]M[/tex] is the slope.

On Comparing, we get:

[tex]y = C, M = 25, x = m, c = 50[/tex]

Therefore, the slope is 25.

Determine whether each relation is a function.

An item sells for $30 and is on sale for 15% off and the sales tax is 8.2%. What is the final cost to the nearest cent? (Calculate the discounted cost first and then find the tax on the discounted cost.)

Answers

Answer:

$27.59

Step-by-step explanation:

You multiply 30 dollars by 0.85 (1-0.15, with the 0.15 being for the 15 percent off). Which gets you to $25.50, and you then multiply it by 1.082 (the 1.082 being the tax, and the .082 part equating to the 8.2% tax percentage).

Step-by-step explanation: This is going to be a long one. In order to find slope you need the formula which is m=y2-y1/x2-x1. Basically what this means is you have to look on each of those graphs and find the points. I’ll do number one as an example. The points are located at (2,1) and (0,-3). Plug these in into your formula as such. M= (-3 - 1) / (0 - 2) which equals 2. If you have questions let me know
