If f(x)= x^2-6x-14 find the value of f(-2) (I prefer some kind of help rather than an answer, but answers are welcome)
Answers
Step-by-step explanation:
In order to figure out what is f(-2), we substitute all the "x" in the function with "-2" like this:
f(-2) = x² - 6x - 14 = (-2)² - 6(-2) -14
Now we can follow PEMDAS:
(-2)² - 6(-2) -14
= 4 + 12 - 14
= 2.
Hence, f(-2) = 2.

Answer: It's C believe me
Explanation: x goes on the number that will be in this case 0.17 since it changes monthly or whatever. Then it's telling you that they already charge him 23.86 dollars so you just add it and of course 28.11 it's the total. Sry if it make sense.

A school held a jump roping contest, Diego jumped rope for 20 minutes . Jada jumped rope for 15 minutes. What percentage of Diego's time is that?
Answers
if you take diego’s total amount and divide it by 4 you’d get 5 so that means 5=1/4 of 20 aka 100% therefore 15 = 3/4 = 75% of 100
Which represents the solution for the inequality -7x +42 < or equal to 28 ?
A. x is greater than or equal to -10
B. x is less than or equal to -10
C. x is less than or equal to 2
D. x is greater than or equal to 2
Answers
Answer:
The answer is D.
Step-by-step explanation:
If we plug in the first two answers (-10):
-7(-10) +42 < or equal to 28
Two negatives equal a positive so: 70+42=112 which is not less than or equal to 28.
So both A and B are not correct, because -10 results in a number GREATER than 28.
This means it has to be either C or D and both use the number +2, so we'll try +1 to solve for C, and +3 to solve for D.
For C: -7(1) +42 < or equal to 28
-7+42=35 which is NOT less than or equal to 28
For D: -7(3) +42 < or equal to 28
-21+42=21 which IS less than or equal to 28
Each number greater than 2 will give you a larger number being subtracted from 42, and that result will always be less than or equal to 28.

X+Y+W=180
(3x-5)+90+2x=180
5x+85=180
5x=95
x=19
Answer:
Angle Y is a right angle, it’s 90 degrees. Angle W is 2x, because it’s opposite angles on a single line with intersecting parallel lines. Triangles have 180 degrees, so adding up all sides creates the equation to solve:
X+Y+W=180
(3x-5)+90+2x=180
5x+85=180
5x=95
x=19

Quiah saved $200 every month that she worked. Her savings are recorded in the data table below. What equation would best describe Quiah's savings?
y = 200x
y = 200x + 300
y = 200x + 500
y = 200x + 200
Answers
Answer:
y = 200x + 300
Step-by-step explanation:
First we multiply the amount she saves every month (200) by the amount of months she works. Since we want an equation that we can use to find Quiah's savings depending on how many months she works, the number of months will be a variable (x). So far we have 200x.
Since she only saves 200 a month and she already has 500 after the first month, we know she had some money saved before. This means we need to add that amount of money to 200x. To find how much money that was, we need to think about the graph. The graph shows us what she has after the month has ended, meaning once she already saved the $200. So to find how much money she originally had we should subtract 200 from 500 which will give us 300. This is how much money she originally had.
This leaves our equation looking like this: y = 200x + 300

y = -(1/3)x + 2
Step-by-step explanation:
Keeping in mind the equation of a line: y = mx + c
Notice three discernible points on the graph: (0,2), (3,1), (6,0).
The first and last points mentioned represent the intercept on y-axis and the intercept on x-axis respectively.
Therefore, when x = 0, y = 2. And 2 = m(0) + c
c = 2
Also, when y = 0, x = 6. And 0 = 6m + 2
6m = -2. And m = -(2/6) = -(1/3)
Therefore, y = -(1/3)x + 2
