Y = (x+2) (-X-1)
Answer the question using null law
Answer:
x = - 2, x = - 1
Step-by-step explanation:
Given
y = (x + 2)(- x - 1)
To solve for x let y = 0, that is
(x + 2)(- x - 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
- x - 1 = 0 ⇒ - x = 1 ⇒ x = - 1
Step-by-step explanation:
y=(x+2) (-x-1)
(45) - (+14)
y= (x+2) (-x-1)
y=-2

Joshua sold his bike for 10% less than payed for it. If he sold the bike for $585, how much did he pay for it.
Answer: $650
Step-by-step explanation:
If he sold the bike 10% less than the original amount which means he sold it as a 10% discount so the person has to pay 90% of the price. And 90% of the price has to equal $585 so we could set up an equation and solve for the price.
90% * x = 585
0.9 * x = 585
0.9x = 585
x = 650
Which means he paid $650 for the bike.

2 3/7 - 1 1/4 please give the answer as a mixed number with the fraction part in the lowest terms :))
Answer:
9/28Step-by-step explanation:
2 3/7 - 1 1/4
2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:
2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4
2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4Next find the Lowest Common Denominator:
L.C.D = 28
L.C.D = 2821 - 12/28
L.C.D = 2821 - 12/28= 9/28
It won't be a mixed number because the denominator is bigger than the numerator.

Point M is the segment bisector. what is the value of x?
============================================
Explanation:
"Bisect" means to cut in half
M is the midpoint as it cuts segment ST in half
SM and MT are the same length
SM = MT
2x+3 = 4x-7
2x-4x = -7-3
-2x = -10
x = -10/(-2)
x = 5
----------
If x = 5, then
SM = 2x+3 = 2(5)+3 = 10+3 = 13
MT = 4x-7 = 4(5)-7 = 20-7 = 13
Both SM and MT are the same length (13 units). This confirms the answer.
Chloe wants to net 50000 on her house. Her closing costs will be 8000 plus 7% commission. She owes 200000 on her loan . What is the minimum contract price that she can accept for the property?
Answer:
$277,419
Step-by-step explanation:
Relevant Data provided as per the question is
Net amount = 50,000
Closing cost = 8,000
Loan amount = 200,000
Commission percentage = 7%
According to the given situation, the calculation of the minimum contract price is shown below:-
[tex]Minimum\ contract\ price = \frac{(Net\ amount\ +\ Closing\ cost\ +\ Loan\ amount) }{Remaining\ percentage}[/tex]
[tex]= \frac{(50,000 + 8,000 + 200,000)}{(100\% - 7\%)}[/tex]
[tex]= \frac{258,000}{93\%}[/tex]
= $277,419
Therefore for calculating the minimum contract price we simply applied the above formula.
write the equation of the line that passes through (3, 4) and (2,-1) in point slope form
Step-by-step explanation:
Using Point Slope formula :
[tex](y - y_1) = \frac{(y_2 - y_1)}{(x_2 - x_1)} (x - x_1)[/tex]
[tex](y - 4) = 5(x - 3)[/tex]
[tex]y = 5x - 11[/tex]
Answer:
The point slope formula is : y-y₁ =m(x-x₁), so first u need to find the value of slope.
Step-by-step explanation:
finding the value of slope:
slope(m)= y₂-y₁ ÷ x₂-x₁
= -1-4 ÷ 2-3
= 5
now finding equation;
y-y₁=m(x-x₁)
y-4 = 5(x-3)
11=5x - y
0= 5x - y -11
therefore equation of line in point slope is : 5x-y-11=0

5. The shape of a dome can be modeled by the equation h = - 2 d 2 + 100 where h is the height (in feet) of the dome from the floor d feet from its center. How far from the center of the dome is the height 50 feet?
6. A cab charges $0.10 per mile and a flat fee of $3.00. Write an equation to model the price y of an x-mile-long cab ride.
7. Use the discriminate to determine the number of solutions to the quadratic equation y = 3 x 2 - 4 x + 6. 8. If f ( x ) = 7 x 2 + 5, compute f ( )3 . 9. Write an equation representing the translation of f ( x ) = 7 x + 3 down 4 units.
Answer:
5. When the dome is 50 feet high, the distance from the center is 5 feet
6. The equation that model the price y of an x-mile long ride is given as follows;
y = 0.1×x + $3.00
7. The discriminant is < 0; The equation has no real root
8. f(3) = 68
9. The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is f(x) = 7·x + 7
Step-by-step explanation:
5. The given equation for the shape of the dome is presented as follows;
h = -2·d² + 100
Where;
h = The height of the dome (in feet)
d = The distance from the center
Therefore, we have;
When h = 50, d is found as follows;
h = -2·d² + 100
50 = -2·d² + 100
50 - 100 = -2·d²
-50 = -2·d²
∴ 2·d² = 50
d² = 50/2 = 25
d = √25 = 5 feet
Therefore when the dome is 50 feet high, the distance from the center is 5 feet
6. The given rate the cab charges per mile, x = $0.10
The rate the cab charges as flat fee = $3.00
Therefore, the price, y a person traveling by cab for x miles is given by the straight lie equation as y = m·x + c,
Where;
m = the slope or rate which in this case = $0.1/hour
c = A constant term which in this case = $3.00
Therefore
y = 0.1×x + $3.00
The equation that model the price y of an x-mile long ride is y = 0.1×x + $3.00
7. The discriminant, b² - 4·a·c of the quadratic equation is (-4)² - 4×3×6 = -56
which is < 0, the equation has no real root
8. Given f(x) = 7·x² + 5
f(3) = 7 × (3)² + 5 = 68
f(3) = 68
9. The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is given as follows;
Down 4 units is equivalent to subtracting 4 from the y-coordinate value, therefore, we have;
f(x) - 4= 7·x + 3
f(x) = 7·x + 3 + 4
f(x) = 7·x + 7
The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is f(x) = 7·x + 7
Find all real zeros of the function f(x)= 12 A. 5,7 B. 12 C. 1 D. none
Answer:
D. NoneStep-by-step explanation:
Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x
f(x) = 12x⁰
From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.
From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.
Hence, there are no real zeros of the function.
a body of mass 2kg travelling with a velocity of 10 m/s what is the momentum this body colloids with another body of equal mass travelling in the same direction with a velocity of 5m/s what is the total momentum of the 2 objects before and after coliision
Your question has been heard loud and clear.
M1 = 2kg , M2=2kg , V1=10m/s V2=5m/s
Total momentum before collision = M1V1+M2V2 = 2*10 + 2*5 = 30kgm/s
Now , by law of conservation of momentum ,
Total momentum before collision = total momentum after collision
Therefore , total momentum of objects before and after collision = 30kgm/s

The test for goodness of fit a. is always an upper tail test. b. is always a two-tailed test. c. can be a lower or an upper tail test. d. is always a lower tail test.
Answer: a. is always an upper tail test.
Step-by-step explanation:
The chi-square goodness-of-fit test is a test to check whether the sample comes from the population with the expected distribution or not.
If the observed frequency is close to the expected frequency, then the square of the deviations will be small. The square of the deviation is divided by the expected frequency to get the weighted frequencies.
If the sum of these weighted squared deviations is large is then it creates a doubt for the distribution claimed other wise not. Therefore, the chi-square goodness-of-fit test is always a right tail test.
Hence correct option is "a. is always an upper tail test. "

Let f(x) = 4x + 8 and g(x) = 2x - 12. Perform the function operation, (f - g)
(x), and then find the domain of the result.
Answer:
See below.
Step-by-step explanation:
So we know that:
[tex]f(x)=4x+8\text{ and } g(x)=2x-12[/tex]
First, know that:
[tex](f-g)(x)[/tex]
Is the same as:
[tex]=f(x)-g(x)[/tex]
Substitute:
[tex]=(4x+8)-(2x-12)[/tex]
Distribute:
[tex]=4x+8-2x+12[/tex]
Combine like terms;
[tex]=2x+20[/tex]
Thus:
[tex]f(g(x))=2x+20[/tex]
This is simply a linear equation.
Thus, the domain is all real numbers.
In interval notation, this is:
