Answer: (f+g)(x)=x²-x-3
Step-by-step explanation:
(f+g)(x) means f(x)+g(x). Since we are given f(x) and g(x), we can add them together.
(f+g)(x)=2x-1+x²-3x-2 [combine like terms]
(f+g)(x)=x²-x-3
Now, we know that (f+g)(x)=x²-x-3.
what is the average rate of change for the quadratic function from x=4 and x=8? enter your answer in the box
Answer:
the image up is your answer to the question.
Answer:
-2
Step-by-step explanation:
Value of the function at x = 4 is 12
Value of the function at x = 8 is 4
change in y is 4 - 12 = -8
change in x is 8 - 4 = 4
x = 4 to x = 8 is -8/4 = -2
there were 96 runners to start a race. in the first half of the race, 1/4 of them dropped out. in the second half of the race, 1/6 of the remaining runners dropped out. how many runners finished the race?
Answer: 60
Step-by-step explanation: 1/4 of 96 is 24 so you subtract that and get 72. And 1/6 of 72 is 12 and you subtract that leaving you with 60 to remain.

Solve for x:2/3=x/9 can someone solve this
Hey there!
ANSWER: [tex]x=6[/tex]EXPLANATION:[tex]\frac{2}{3}=\frac{x}{9}[/tex]
For the first step, we will need to use the cross multiplying method.
[tex]\frac{2}{3} =\frac{x}{9}\\ (2)*(9)=(x)*(3)\\18=3x[/tex]
Now let's flip.
[tex]3x=18[/tex]
Now for the final step, we will have to divide both sides by 3.
[tex]\frac{3x}{3} equals\frac{18}{3}[/tex]
Simplify 18/3.
[tex]18/3=6\\6(ANSWER)[/tex]

Hey there!!!
Here,
Triangle BCM and triangle ABC are 2 isosceles triangle.
Solving in triangle BCM.
Angle CBM = 31° { it is the base angle.}
Angle CBM + 31° + angle BCM = 180° { sum of interior angle of a triangle is 180°}.
31°+31°+ angle BCM = 180°
Angle BCM = 180° - 62°
Therefore the measure of angle BCM = 118°.
Again,
Solving in triangle ABC.
Angle BCM + angle ACB = 180° { being linear pair}.
118°+ angle ACB = 180°
Angle ACB = 180°-118°
Therefore the measure of angle ACB is 62°.
Angle ACB = angle BAC (Base of an isosceles triangle).
Therefore the measure of angle BAC = 62°.
Now, To find x,
Angle BAC + angle ACB + angle x = 180° (sun of interior angle of a triangle is 180°).
62°+62°+angle x = 180°
Therefore the measure of angle x is 56°.

Solve 5x + 2 = 3x -8
Step-by-step explanation:
5x-3x=-8-2
2x=-10
x=-10/2
x=-5
Answer: x=-5
Step-by-step explanation:
Given
5x + 2=3x -8
Subtract 2 on both sides
5x + 2 - 2=3x - 8 - 2
5x=3x-10
Subtract 3x on both sides
5x - 3x=3x - 10 -3x
2x=-10
Divide 2 on both sides
2x / 2=-10 / 2
x=-5simplify the following equation: (5 + 3)²

If I spent $3.87 on grapes at Tom Thumb and I bought 3.05 pounds. How much was each pound?
(round to the nearest hundredths place because it is money)
Answer:
$1.26 or $1.27 depending on whether you round up or down. The number in the thousandths is an 8 though
Step-by-step explanation:
You would divide 3.05 by itself to get one pound
and then 3.87 by 3.05. You have to divide both numbers so you get the number for one pound.
3.87÷3.05=1.268852459
Round up or down depending on what your teacher would want you to do so that the decimal is in the hundreths like money.

State the domain and range in interval notation
Which statement is true?
A. 3 2/5 < 2 4/5
B. 2/3 > 1 7/3
C. 4 1/4 > 2 3/4
D. 1/2 < 1/4
Answer: C. 4 1/4 > 2 3/4
Step-by-step explanation: Option C is correct because when comparing mixed numbers, we first compare the whole numbers. In this case, 4 is greater than 2. Then, if the whole numbers are the same, we compare the fractions. In this case, 1/4 is greater than 3/4. Therefore, 4 1/4 is greater than 2 3/4.

Find the area of a square with a side of length 2 Square root of 3+6 square root of 7 inches
Answer:
(264+24√21) in²Step-by-step explanation:
Area of a square = Length * Length
A = L²
Given the length of a square as [tex]2\sqrt{3}+6\sqrt{7}[/tex] inches' The area of the square will be calculated as shown;
[tex]A = (2\sqrt{3}+6\sqrt{7})^2\\\\A = (2\sqrt{3}+6\sqrt{7})(2\sqrt{3}+6\sqrt{7})\\\\A =(2\sqrt{3})(2\sqrt{3})+(2\sqrt{3})(6\sqrt{7})+(6\sqrt{7})(2\sqrt{3})+(6\sqrt{7})(6\sqrt{7})\\\\A = 4\sqrt{9}+12\sqrt{21}+12\sqrt{21}+36\sqrt{49}\\\\A = 4(3)+24\sqrt{21}+36(7)\\ \\A = 12+24\sqrt{21}+252\\\\A = 264+24\sqrt{21}[/tex]
Hence the area of the square is (264+24√21) in²
The sum of two numbers is 82. One number is three less than four times the other. Find the two numbers.
Answer:
17 , 65
Step-by-step explanation:
x+ y = 82
y = 4x - 3
=====================
Put the second equation into the first.
x + 4x - 3 = 82
5x = 85
x = 85/5
x = 17
17 + y = 82
x = 82 - 17
x = 65
To solve x2−8x=10 by completing the square, what should be added to both sides?
Answer:
16 will be added.
Step-by-step explanation:
Given equation is,
x² - 8x = 10
To convert this equation into a square form we will follow the following steps,
Step (1). x² - 2(4x) = 10
Step (2). x² -2(x)(4) + 16 = 10 + 16
Step (3). x² - 2(4)(x) + 4² = 26
Step (4). (x - 4)² = 26
In step (2) we have added 16 to both the sides of the equation to make is a perfect square.
The probability that an event will happen is P(E)=
34/41.
Find the probability that the event will not happen.
Answer:
7/41
Step-by-step explanation:
There is a 34/41 probability that this event will happen so to find the probability of which the event will not happen, the subtract 34 from 41 to get your answer.
41-34=7
Therefore, 7/41 is the answer.
Ps. is the P(E) included in the main question? if it is, the the answer might differ from the one I am giving you.
What is 17 percent of 425 please show step by step. I’m really struggling
Answer:
72.25
Step-by-step explanation:
17% of 425
=17\100 ×425
=7225/100
=72.25
Answer:
72.25
Step-by-step explanation:
Lets say you are trying to find p percent (p%) of a number n. To do this, you would divide the percent (p) by 100 and multiply it by the number (n). In other words:
[tex]n*\frac{p}{100}[/tex]
We can use this to find 17 percent of 425. 17 would be our percent and 425 would be our number.
[tex]425*\frac{17}{100}=425*0.17=72.25[/tex]
So 17 percent of 425 would be 72.25.
