Answer:
Answer below. Hope it helps.
Step-by-step explanation:
a. 2x + (x - 6) {x = 14}
= 2*14 + (14 - 6)
= 28 + 8
= 36
b. n² + n + 1 {n = 8}
= 8² + 8 + 1
= 64 + 9
= 73
c. (r - 10) (r + 2) {r = 13}
= (13 - 10) (13 + 2)
= 3 * 15
= 45

Answer:
45/2
Step-by-step explanation:
ashjasdhkjasdha hello there
There are two people and there are 45 minutes to shoot the ball. As both people shoot for the exact same time, you have to divide 45 by 2 to split the time into two equal halves. Thus, the answer is 45 divided by 2, or just 45/2.

A company finds that if it charges x dollars for a cell phone, it can expect to sell 1,000−2x phones. The company uses the function r defined by r(x)=x⋅(1,000−2x) to model the expected revenue, in dollars, from selling cell phones at x dollars each. At what price should the company sell their phones to get the maximum revenue?
Answer:
$500 will give the company the maximum revenue
Step-by-step explanation:
Given
[tex]r(x) = x (1000 - 2x)[/tex]
Required
Price to generate maximum revenue
We have:
[tex]r(x) = x (1000 - 2x)[/tex]
Open bracket
[tex]r(x) = 1000x - 2x^2[/tex]
Rewrite as:
[tex]r(x) = - 2x^2 + 1000x[/tex]
The maximum value of x is calculated using:
[tex]x = -\frac{b}{2a}[/tex]
Where:
[tex]f(x) = ax^2 + bx + c[/tex]
So:
[tex]a \to -2[/tex]
[tex]b = 1000[/tex]
[tex]c = 0[/tex]
[tex]x = -\frac{b}{2a}[/tex]
[tex]x = -\frac{1000}{-2}[/tex]
[tex]x = \frac{1000}{2}[/tex]
[tex]x = 500[/tex]

Answer:
2x+h
Step-by-step explanation:
f(x+h) means that wherever there's an x in the function f(x) we plug in a x+h
we have
(x+h)²+9
Let's start with the numerator
(x+h)²+9-(x²+9)
Distribute the exponent
x²+2xh+h²+9-x²-9
Which gives us
2xh+h²
Divide the whole thing by h to give us
2x+h
Trevor's mom bought 3 gallons of fruit juice at the store how many fluid ounces of fruit juice did Trevor‘s mom buy?
Answer: 384 fluid ounces
Step-by-step explanation:
First and foremost, when converting gallons to ounces, the conversion rate is:
1 gallon = 128 ounces
Therefore, since Trevor's mom bought 3 gallons of fruit juice, to convert it to to ounces, we have to multiply by 128. This will then be:
1 gallon = 128 ounces
3 gallons = 128 ounces × 3
= 384 fluid ounces of fruit juice.

Answer:
Mixed Number: 7 And 1/10
Improper Fraction: 71/10
Please give me Brainliest if I'm right ! :)
Answer:
Mixed Number: 7 1/10
Improper Fraction: 71/10
Step-by-step explanation:
A Mixed Number is a Number with a fraction as part of it so 7 is a whole number, so this is the "number" part. .1 isnt a whole number, so you find out what the simplified form of .1 is, and you get 1/10. Put them together and you get 7 1/10. An improper fraction is where the number becomes only a fraction, no whole numbers allowed! you can find out 1 = 10/10 so this means 7 = 70/10. Add the .1 (1/10) to this and you get 71/10.

The weight of four puppies are shown in pounds 9.5 9 3/8 9.125 9 3/4 which list shows these weights in order from greatest to least?
Answer:
9. 3 ÷ 4, 9.5, 9. 3 ÷ 8, 9.125
Step-by-step explanation:
Given that
The weight of four puppies are 9.5 9 3 ÷ 8 9.125 9 3 ÷ 4
We need to find out the weight from high to low
So,
First we place the number in decimals
After this, we line all up
Now place the numbers from high to low
The above shows the correct order
Therefore the same would be considered and relevant

SAT scores are normally distributed with a mean of
500 and a standard deviation of 60. Find the z-score
of an SAT score of 380.
Answer:
the z-score for the sat score of 380 is 2
Step-by-step explanation:
the way i got this is you got to take the standard deviation value and subtract it from the mean since the value 380 is less than 500.
500-60=440-60=380
so the answer would be a z-score of 2
solve the quadratic equation:
3x^2+x-5=0
3x²+x-5=0
a = 3, b = 1, c= -5
-> ∆ ( delta ) = b²-4ac = 61 > 0
-> x1 =( -b+√∆ )÷ 2a =...
x2 = (-b-√∆)÷2a =...
p/s: do your teachers teach you how to use ∆ ( delta ) in maths calculation ? i live in europe and our teachers teach us that way. however, it is a rịght and fast way. you should learn it.
write the equation of a circle with a center at (-1,2) and a radius of 7
Answer:
[tex](x+1)^2+(y-2)^2=49[/tex]
Step-by-step explanation:
The standard form for the equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where r is the radius, and the center is (h, k).
(h, k) = (-1, 2), r = 7
[tex](x-(-1))^2+(y-2)^2=7^2\\\\(x+1)^2+(y-2)^2=49[/tex]
Find the slope of the line that passes through ( 25,20 ) and ( 11,-20 )

Slope = 20/7
Express the solution graphically of – }(2x + 1) < 3.
Answer:
The third one counting from the top.
Step-by-step explanation:
We have the inequality:
(-1/3)*(2x + 1) < 3
The first thing we need to do is isolate x on one side of the inequality.
First we can by -3 in both sides of the inequality, and remember, because we are multiplying by a negative number, the inequality sign changes its direction:
(-3)*(-1/3)*(2x + 1) > 3*(-3)
(2x + 1) > -9
Now we can subtract 1 in both sides:
2*x + 1 - 1 > -9 - 1
2*x > -10
Now we can divide by 2 in both sides:
2*x/2 > -10/2
x > -5
Then we should see a number line such that all the points at the right of -5 are colored.
The correct option is the third one, counting from the top.
The theater sells two types of tickets: adult tickets for $7 and child tickets for $4. Last night, the theater sold a total of 76 tickets for a total of $469. How many adult tickets did the theater sell last night?
Answer:
55 tickets for adults
Step-by-step explanation:
Start by setting up two equations. One equation will be the total amount of money spent and the other is the total amount of tickets sold. a is the # of adult tickets and c is the # of children tickets sold.
7a+4c=469
a+c=76
Now solve for c in the second equation. Then use that to substitute for c in the first equation.
c=76-a
7a+4(76-a)=469
7a+ 304-4a =469
7a+4a=165
3a=165
a=165/3
a=55
