Answer: 2,695
Step-by-step explanation:
5-6+8*674/2
Multiply 8 and 674
5-6+5,392/2
Divide 5,392 by 2
5-6 + 2,696
Subtract 6 from 5
-1 + 2,696
Add
2,695
Step-by-step explanation:
5 - 6 = -1
-1 + 8 = 7
7 x 674 = 4,718
4,718 / 2 = 2,359
Solve for x.
8(x + 1) - 31x + 4) = 7(2 - x)
Answer: -8.5625
Step-by-step explanation:
Use the distributive property.... ex: 8(x+1)= 8x+1 (by multiplying both by 8)
8x+1-31x-124=14-7x
Combine like variables
-23x-123=14-7x
Bring like variables to the same side of the equation by changing the sign(+,-)
-16x=137
Divide -16 by both sides
x=-8.5625

A box contains 20 miniature golf putt-putt balls; 10 are
yellow, 6 are red, and 4 are pink. What is the probability of
picking a red golf ball, replacing it, and then picking a
yellow golf ball? Written as a percent?
Answer: The answer is provided below
Step-by-step explanation:
From the question, a box contains 20 miniature golf putt-putt balls out of which 10 are yellow, 6 are red, and the remaining 4 are pink.
The probability of picking a red golf ball will be:
= 6/20 × 100
= 600/20
= 30%
If the red ball is replaced, the probability of picking a yellow golf ball will be:
= 10/20 × 100%
= 50%
can somone answer number 12, I really need it bad, please help .
Answer:
-24
Step-by-step explanation:
f(x) = 3x^3 -12x^2
f(2) = 3 * (2)^3 - 12 (2)^2
= 3 (8) - 12 (4)
= 24 - 48
= -24
Answer:
D. f(2)= -24
Step-by-step explanation:
To solve this problem, we want to find what f(x), or y is, when x is equal to 2.
f(x)=3x³-12x²
Therefore, we can substitute 2 in for every x.
x=2
f(2)=3(2³)-12(2²)
Evaluate the exponents first.
2³ is equal to 2*2*2, which equals 8.
2² is equal to 2*2, which equals 4.
f(2)=3(8)-12(4)
Multiply 3 and 8.
f(2)=24-12(4)
Multipy 12 and 4
f(2)=24-48
Subtract 48 from 24.
f(2)=-24
Therefore, the correct answer is D. f(2)= -24
Translate this sentence into an equation.
The product of Victor's age 7 and is 84 .
Use the variable v to represent Victor's age.
Answer:
The product of Victor's age and 7 is 84 in equation form is 7v=84
Step-by-step explanation:
Let v be the Victor's age.
We are supposed to Translate this sentence into an equation
The product of Victor's age and 7 is 84
Victor's age = v
Product of victor's age and 7 =[tex]7 \times v[/tex]
We are given that their product is 84
So,[tex]7 \times v =84[/tex]
Hence The product of Victor's age and 7 is 84 in equation form is 7v=84
if f(x)=6x^2-4 and g(x)=2x+2 find (f-g)(x)
Answer: [tex](f-g)(x)=6x^2-2x-6[/tex]
Step-by-step explanation:
[tex]f(x)=6x^2-4\\g(x)=2x+2\\(f-g)(x)=[/tex]
Take each function and subtract them.
[tex](f-g)(x)=(6x^2-4)-(2x+2)[/tex]
The trick here is that the negative sign changes all of the signs inside the parentheses.
[tex](f-g)(x)=6x^2-4-2x-2[/tex]
Combine like terms;
[tex](f-g)(x)=6x^2-2x-6[/tex]

Use the identity (x^2+y^2)^2=(x^2−y^2)^2+(2xy)^2 to determine the sum of the squares of two numbers if the difference of the squares of the numbers is 5 and the product of the numbers is 6.
Answer:
Step-by-step explanation:
(x^2+y^2)^2=(x^2)^2+2x^2y^2+(y^2)^2
Adding and substracting 2x^2y^2
We get
(x^2+y^2)^2=(x^2)^2+2x^2y^2+(y^2)^2 +2x^2y^2-2x^2y^2
And we know a^2-2ab+b^2=(a-b)^2
So we identify (x^2)^2 as a^2 ,(y^2)^2 as b^2 and -2x^2y^2 as - 2ab. So we can rewrite (x^2+y^2)^2=(x^2 - y^2)^2 + 2x^2y^2 + 2x^2y^2= (x^2 - y^2)^2+4x^2y^2= (x^2 - y^2)^2+2^2x^2y^2
Moreever we know (a·b·c)^2=a^2·b^2·c^2 than means 2^2x^2y^2=(2x·y)^2
And (x^2+y^2)^2=(x^2 - y^2)^2 + (2x·y)^2

4. Nine fruit juice bottles contain 4 1/2 litres of fruit juice between them.
How much juice do five bottles hold?
[tex]4 \frac{1}{2} litres[/tex]
Answer:
2[tex]\frac{1}{2}[/tex] litres or 2.5 litres
Step-by-step explanation:
From the question, 9 fruit juice bottles contain 4[tex]\frac{1}{2}[/tex] litres of fruit juice. Therefore, to find how many litres of fruit juice would be contained in 5 fruit juice bottles, you multiply 5 by 4[tex]\frac{1}{2}[/tex] litres and you divide the product by 9.
i.e. Let the quantity of the fruit juice for 5 bottles be x.
9 juice bottles ===> 4[tex]\frac{1}{2}[/tex] litres
5 juice bottles ===> x
∴x = [tex]\frac{5 * 4\frac{1}{2} }{9} litres[/tex]
x = [tex]\frac{5 * 4.5}{9} litres[/tex]
x = [tex]\frac{22.5}{9} litres[/tex]
x = 2.5 litres or 2[tex]\frac{1}{2}[/tex] litres

Answer:
The answer is x = 4
Step-by-step explanation:
1. First you need to distribute the 3/4 * (x + 8). This looks like (3/4) * (x) + (3/4) * (8) = 9
2. Next you simplify the distributed equation, 3/4x + 6 = 9
3. Now subtract 6 from both sides, 3/4x = 3
4. Multiply both sides by 4/3, 4/x * 3/4x = 3 * 4/3
5. Simplify, x = 4
What is the slope of the line whose equation is
y = - 3x + 6?
A. -1/2
B. 2
C. -3
D. 6
Answer:
-3
Step-by-step explanation:
Because it is multiplied by x
Answer:
C. -3
Step-by-step explanation:
The equation of the line is in point slope form.
y=mx+b
where m is the slope and b is the y-intercept.
The number that is multiplied by x is the slope. The number that is added or subtracted from x is the y-intercept.
We have the equation:
y=-3x+6
-3 is being multiplied by x (-3*x=-3x). 6 is being added on to -3x.
Therefore, the slope is -3 and the y-intercept is 6.
Since -3 is the slope, C is the correct answers.

what is the slope of the line shown below (4,8) (2,2)
Answer:
slope = 3
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
= (8-2)(4-2)
= 6/2
= 3
Answer:
If those are 2 points on the line, then the slope is 3.
Step-by-step explanation:
slope is rise over run. (8-2)/(4-2) = 6/2 = 3

Find the focus of the parabola 2x^2=-y
Answer:
(0, -1/2)
Step-by-step explanation:
Rewrite this as y = -2x^2. Because of the negative sign, as well as the fact that y is the dependent variable, we know that the graph of this parabola opens downward.
Comparing y = -2x^2 with
y = 4px^2, we see that 4p = -2, or p = -1/2.
The focus of this parabola is below the x-axis: (0, -1/2).
On one day, the stock of Seraj Food Technologies went up by 30%. The next day, the stock fell by 30% Over the two days, the stock fell overall by "x" percent. What is "x"?
Answer:
x = 9
Step-by-step explanation:
The first day, the value was multiplied by 1+30% = 1.30.
The second day, the value was multiplied by 1-30% = 0.70.
Over the 2-day period, the value was multiplied by 1+x%:
1 -x/100 = (1.30)(0.70) = 0.91
x/100 = 1 -0.91
x = 9
The stock fell by 9% overall.
HELP FAST 5√6 As a Whole Radical
Answer:
sqrt(150)
Step-by-step explanation:
We want to write the whole number inside the radical
5 = sqrt(5*5)
We know that sqrt(a) sqrt(b) = sqrt(ab)
5 * sqrt(6)
sqrt(5*5) * sqrt(6)
sqrt(5*5*6)
sqrt(150)
Answer:
[tex]\sqrt{150}[/tex]
Step-by-step explanation:
since the 5 is out of the sqrt root, you need to ^2 to put it back in again.
[tex]5^{2}[/tex]=25
and then in the sqrt you multiply the two variables
6* 25 = 150
so the answer is sqrt{150}
After first entering the ocean, a scuba diver descends to a depth 18 feet below the surface of the water. The diver then ascends 7 feet before descending 18 feet again. What is the final depth of the diver below the surface of the water?
Answer:
The diver is 29 ft below the water surface
Step-by-step explanation:
Here, we are interested in calculating the diver’s final depth before the surface of the water.
Firstly he descends 18 feet before ascending 7 feet. His depth would thus be;
18ft -7ft = 11 ft initially
It is at this point he descended a further 18 feet which makes his total feet of descent = 11 ft + 18 ft = 29 ft
This means he is 29 ft below the surface of the water
Answer:
-29
Step-by-step explanation:
The diver is 29 ft below the water surface

What is the average rate of change from x = 0 to x = −2?
How I got that answer:
The graph shows the two points (0,-4) and (-2,2) are on the parabola. The x coordinates of both points are from x = 0 and x = -2 as given in the instructions. Compute the slope of the line through those points. The slope of this line is the exact same as the average rate of change from x = -2 to x = 0.
m = (y2 - y1)/(x2 - x1)
m = (2 - (-4))/(-2-0)
m = (2 + 4)/(-2-0)
m = 6/(-2)
m = -3
A negative slope means the line slopes downhill as you move from left to right. This is a negative average rate of change.
