Answer:
D
Step-by-step explanation:
Δ CED and Δ CAB are similar thus the ratios of corresponding sides are equal, that is
[tex]\frac{CE}{CA}[/tex] = [tex]\frac{ED}{AB}[/tex] , substitute values
[tex]\frac{x}{156-x}[/tex] = [tex]\frac{7}{84}[/tex] = [tex]\frac{1}{12}[/tex] ( cross- multiply )
12x = 156 - x ( add x to both sides )
13x = 156 ( divide both sides by 13 )
x = 12
Thus
AC = 156 - x = 156 - 12 = 144 → D
Answer:
D. 144
Step-by-step explanation:
Triangle BAC is similar to triangle DEC, so you can set up a ratio:
[tex]\frac{84}{156-x} = \frac{7}{x}[/tex]
Then cross multiply
84x = 7 (156 - x)
84x = 1092 - 7x
Add 7x to both sides.
91x = 1092
Divide both sides by 91.
x = 12
AC = 156 - x
AC = 156 - 12
AC = 144

A smartphone device has a certain cost. A person gets this smartphone and signs up for a monthly wireless plan with a fixed base price plus a charge per GB of data used. Which is the Independent Variable in this scenario? A. The cost of the smartphone device. B. The charge per GB of data used. C. The number of GB data used. D. The total amount they pay for the new device and new phone plan in the first month.
Answers
Answer:
C. The number of GB data used.
Step-by-step explanation:
Independent variable is the variable that is changed or manipulated in an experimental scenario. The independent variable is changed in order to effect response in another variable called Dependent variable, which is dependent on the independent variable.
According to this question, a person gets a smartphone at a certain cost and signs up for a monthly wireless plan with a fixed base price plus a charge per GB of data used. One would observe that the variable changed here is the "Number of GB of data used", hence, it is the INDEPENDENT VARIABLE. The charge per GB of data used is dependent on the number of GB of data used hence it is the dependent variable.
Answer:
C. The number of GB data used.

Step-by-step explanation:
given slope m = 4
point (2, -3) for (x1, y1)

y - y1 = m(x- x1)
y - (-3) = 4 (x -2)
y + 3 = 4x - 8, simplify

O {(1, -7), (2, – 8), (-2, 7), (1, 8)}
Answers
Answer:
B
Step-by-step explanation:
For a relation to be a function, it must fit the following criteria:
Each input must be matched to exactly one output. Inputs cannot repeat*. Outputs can. *If inputs do repeat, they must be equal the same output as the other inputs.So, let’s go through each of the choices.
Choice A)
In this relation, -7 repeats. It simultaneously equals -1 and -8. So, this is not a function since it’s repeating and it doesn’t equal to same.
Choice B)
In this relation, none of the inputs are repeating. Therefore, B is the corrrect answer.
Choice C)
In this relation, -2 repeats four times. And each time, it equals something different. Therefore, C is not a function.
Choice D)
Here, 1 repeats twice, equalling both -7 and 8. Since it appeared more than once and is not equal to the same thing, D is not a function.
Therefore, our answer is B.

What is the Equation of a line that has a slope

Answers
Answer:
y= -3x + 7:)
Step-by-step explanation:
Hope this helps!
Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute (4, - 5) into the partial equation
- 5 = - 12 + c ⇒ c = - 5 + 12 = 7
y = - 3x + 7 ← equation of line
s(x)= -3(x-2/3) + 19; s(x) = 0
Answers
Answer:
x = 7
Step-by-step explanation:
Given s(x) = - 3(x - [tex]\frac{2}{3}[/tex]) + 19 and s(x) = 0, then equate the right sides, that is
- 3(x - [tex]\frac{2}{3}[/tex] ) + 19 = 0 ( add 19 to both sides )
- 3(x - [tex]\frac{2}{3}[/tex] ) = - 19 ← distribute the parenthesis
- 3x + 2 = - 19 ( subtract 2 from both sides )
- 3x = - 21 ( divide both sides by - 3 )
x = 7

These are the four after 6:4. I didn't know which you needed.
Answer:
3:2
Step-by-step explanation:
If you want to simplify 6:4, it also makes an equivalent equation. To simplify this, we divide by the greatest number that both numbers can be evenly divided by. 6 and 4 can both be divided by 2, which is the biggest number we can divide both numbers by.
6/2=3
4/2=2
The ratio is now simplified/equivalent to 3:2.

Add both lengths and you see the overlap thats 12 cm so subtract that to get the length.
Answer:
1.94 m
Step-by-step explanation:
1 meter=100cm
Then we need to convert the two lengths which is 135 cm and 83 cm
so then since it is overlap we multiply by two 12 cm*2= 24 cm
Then we add 135 and 83= 135+83 = 218 cm
218 cm - 24 cm = 194 cm
So then 194 cm to m = 1.94 m

The profit a company urns every month depends on the amount of product sold, p, for $855 each and the amount spent in rent, utilities and other expenses, which always totals to $6,780. The CEO of the company earns 15% of this profit. How much does the CO heard if the company sells 250 products in a given month?
Answers
Answer:
CEO earns $31,045.5
Step-by-step explanation:
Price of each product = $855
Number of product sold = 250
Total revenue = price × quantity
= 855 × 250
= $213,750
Total expenditure = $6,780
Profits = Total revenue - Total expenditure
= 213,750 - 6,780
= $206,970
Profits = $206,970
The CEO of the company earns 15% of this profit
Amount CEO earns = 15% of $206,970
= 15/100 × 206,970
= 0.15 × 206,970
= $31,045.5
CEO earns $31,045.5
