Step-by-step explanation:
let 'x' = years
y = 30x + 800
y = -25x + 1240
30x + 800 = -25x + 1240
55x = 440

Mclane is playing a game where you get 5 points for correct answers and lose 3 points for incorrect answers. If he gets 6 questions correct and 7 questions incorrect, what was his final score?
Answer:
9
Step-by-step explanation:
final score = total points for correct answer - total points for wrong answer
total points for correct answer = 5 x 6 = 30
total points for wrong answer = 7 x 3 = 21
30 - 21 = 9 points
If f(x) =- 2x + 5, find f(4x)
Answer:
[tex]f(4x)=-8x+5[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)=-2x+5[/tex]
And we want to find:
[tex]f(4x)[/tex]
So, by substitution, we acquire:
[tex]f(4x)=-2(4x)+5[/tex]
Multiply. So, our answer is:
[tex]f(4x)=-8x+5[/tex]

Answer:
x = angle left of (4x+5) [ᴄᴏʀʀᴇsᴘᴏɴᴅɪɴɢ ᴀɴɢʟᴇs]

Answer:
52/6 = 8 and 2/3
Step-by-step explanation:
52 divided by 6 is 8 and 2/3
6 multiplied by 8 is 48
52-48 is 4
so 52/6 is 8 remainder 4
or you can divide 4 by 6
4/6 = 2/3
so it can also be 8 and 2/3
52 divided by 6 as a fraction in its simplest form is 8 2/3.
To express 52 divided by 6 as a fraction, you simply write it as:
52 / 6
To simplify the fraction, find the greatest common divisor (GCD) of the numerator (52) and the denominator (6), and then divide both the numerator and denominator by the GCD.
The GCD of 52 and 6 is 2.
Divide both the numerator and denominator by 2:
(52 / 2) / (6 / 2)
This simplifies to:
26 / 3
now, we have,
Divide 26 by 3:
26 ÷ 3 = 8 with a remainder of 2
The whole number part is 8, and the remainder (2) becomes the new numerator.
The denominator remains the same.
So, 26/3 as a simplified mixed number is: 8 2/3
So, 52 divided by 6 as a fraction in its simplest form is 8 2/3.

an article bought a television for 2500 dollars and sold for 2325dollars find a.loss b.loss%
Answer:
Loss= $175
Loss %= 7%
Step-by-step explanation:
First of all, you find the difference between 2500 and 2325 which is 175, as his has decreased, it is a loss of $175
To find the percentage you do the difference over the original amount
So 175/2500 which will give you 0.07
0.07 x 100 will give you 7%

Find a polynomial f(x) of degree 3 with real coefficients and the following zeros. -2,- 2+i.
Answer:
f(x) = x^3 + 2x^2 + x + 2
Step-by-step explanation:
If -2 + i is a zero, then -2 - i must also be a zero.
These zeros are -2, -2 + i and -2 - i, and the corresponding factors of the polynomail f(x) are (x + 2), (x + 2 - i) and (x + 2 + i).
(x + 2 - i) and (x + 2 + i) multiplied together becomes x^2 + 1.
Multiplying this result by the 3rd and last factor, (x + 2), we get
(x^2 + 1)(x + 2) = x^3 + 2x^2 + x + 2
Check, using synthetic division. What are the factors of x^3 + 2x^2 + x + 2?
-2 / 1 2 1 2
-2 -2 -2
-----------------------
1 0 -1 0 Since the remainder is zero, we know that
(x + 2) is a factor and -2 is a root.

Find the error for the proposed solution. Then correct the proposed solution.
2x + 18 = 16
2x = 34
2x 34
2 2
X = 17
Answer:
The error is in the second line.
x = -1
Step-by-step explanation:
When solving for "x", you are trying to isolate it, or move everything else to the other side. You may have learned that "what you do to one side, you do to the other" .
2x + 18 = 16
2x = 34 18 was added to the right side, but not to the other.
If you add 18 on both sides, then the equation would be:
2x + 36 = 34 "x" is not being isolated.
Instead, you should subtract 18 from 16.
Correct solutions steps:
2x + 18 = 16
2x + 18 - 18 = 16 - 18 Subtract 18 from both sides to cancel out 18
2x = -2
2x/2 = -2/2 Divide both sides by 2
x = -1 Final answer

Find the area of the shaded regions below. Give your answer as a completely simplified exact value in terms of pi
Answer:
18π cm²
Step-by-step explanation:
The area of the shaded region = Area of Sector
Radius, r =
The value of θ = 80°
Recall :
Area of Sector :
A = θ / 360 * πr²
A = (80 / 360) * π * 9²
A = 0.222222 * π * 81
A = 18π cm²
I NEED HELP ON THIS GEOMETRY QUESTION!!!
Answer:
a. 4
Step-by-step explanation:
Copy and paste this:
I now that the area is: A = b×h/2, so: 16 = (x+4)(x)/2
-> x²+4x-32=0 -> x= -8 and x=4
x = -8 is impossible, so x=4
Answer: A. 4
Step-by-step explanation:
The equation for the area of a triangle is height times( base divided by 2)
4 + 4 = 8
8/2 is 4
4 times 4 is 16
