Type the correct answer in each box. Use numerals instead of words. Consider the quadratic equation -x2 − 6x + 6 = 0.
The question is incorrect
Complete Question
Type the correct answer in each box. Use numerals instead of words. Consider the quadratic equation -x² − 5x + 6 = 0.
Answer:
(−x + 1)(x + 6)
Step-by-step explanation:
-x² − 5x + 6
-x² - 6x + x + 6
(-x² - 6x) +(x +6)
= -x (x + 6) + 1(x +6)
=(−x + 1)(x + 6)
This line has a slope
of -3 and passes
through the point
(4, -10)
Answer:
Step-by-step explanation:
y= mx+c
-10= -3 x 4 +c
-10= -12 +c
c= 2
then, y= -3x+2 would be the answer, if you were wanting the equation of the line.
Answer:
y+10=-3(x-4)Step-by-step explanation:
to understand thisyou need to know about:linear equation i.g point-slope formPEMDASgiven:slope or m=-3
(x1,y1)=(4,-10)
to find:point-slope form of linear equation
let's solve:point-slope form of a linear equation is

There are 100 people in a sport centre. 67 people use the gym. 62 people use the swimming pool. 56 people use the track. 38 people use the gym and the pool. 31 people use the pool and the track. 33 people use the gym and the track. 16 people use all three facilities. A person is selected at random. What is the probability that the person uses exactly one of the facilities?
Answer:
0.3 or 30%Step-by-step explanation:
Number of people using more than one sport facility:
38 - gym and pool31 - pool and track33 - gym and track16 - all threeSince 16 is counted for all three, total number of those using more than one facility is therefore:
38 + 31 + 33 - 16*2 = 70Number of people using exactly one facility is:
100 - 70 = 30Probability of the person using exactly one facility is:
30/100 = 0.3 or 30%4

What is the total number of people in the eight households? a.16. B. 64. C.14. D.48
Answer: 48
Step-by-step explanation:
Here's the complete question:
The mean number of people per household in eight households is six people. what is the total number of people in the eight households?
First and foremost,we should note that mean means the average of a given set of numbers.
Since the mean number of people per household in eight households is six people, the total number of people in the eight households would be calculated by multiplying 6 by 8. This would be:
= 6 × 8
= 48 people

8 orchid plants and 12 lily plants sell for $362. 12 orchid and 8 lily plants sell for $388. How much does the lily plant charge
Answer:
$15.5
Step-by-step explanation:
let a = price of one orchid plant
8 orchids would cost 8 x a = 8a
12 orchids would cost 12 x a = 12a
Let b = price of one lily plant
12 lilies would cost 12 x b = 12b
8 lilies would cost 8 x b = 8b
8a + 12b = 362 -- eqn 1
12a + 8b = 388 -- eqn 2
to solve, multiply equation 1 by 8 and equation 2 by 12
64a + 96b = 2896 equation 3
144a + 96b = 4656 equation 4
substract equation 4 from 3
80a = 1760
a = $22
Substitute for a in eqn 1 and solve for b
8(22) + 12b = 362
b = $15.5
The length of a garden box is 6 feet longer than 4times the width. If the length of the garden box is 22 feet, what is the width of the garden box?
Wil name Branilest
Answer:
Width of the garden box = 4 feet
Step-by-step explanation:
Given that:
Length of garden box = 22 feet
Let,
w be the width of garden box
It is also given that:
The length of a garden box is 6 feet longer than 4 times the width.
L = 4w + 6
Putting L = 22
22 = 4w + 6
22 - 6 = 4w
4w = 16
Dividing both sides by 4
[tex]\frac{4w}{4}=\frac{16}{4}\\w=4[/tex]
Hence,
Width of the garden box = 4 feet

Answer:
A) {-1,2}
Step-by-step explanation:
square both side of the equation. Then:
x+2=x^2
simplify:
x^2-x-2=0
factor:
(x+1)(x-2)=0
then:
x=-1, x=2
Answer:
B
Step-by-step explanation:
Given
[tex]\sqrt{x+2}[/tex] = - x ( square both sides )
x + 2 = (- x)² = x² ( subtract x + 2 from both sides )
0 = x² - x - 2 ← in standard form
0 = (x - 2)(x + 1) ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x + 1 = 0 ⇒ x = - 1
As a check
Substitute these values into the equation and if both sides are equal then it is a solution.
x = 2 : left = [tex]\sqrt{2+2}[/tex] = [tex]\sqrt{4}[/tex] = 2, right side = - 2 ← not equal
Thus x = 2 is an extraneous solution
x = - 1 : left = [tex]\sqrt{-1+2}[/tex] = [tex]\sqrt{1}[/tex] = 1 , right side = - (- 1) = 1 ← equal
Thus the solution is { - 1 } → B
Angles A and B are supplementary. Angle A is equal to 20 degrees plus x, while Angle B is equal to 10 degrees plus 2 x. What is x?
Answer:
50 degrees
Step-by-step explanation:
Given
<A = 20 + x
<B = 10+2x
Since <A and <B are supplementary then the sum of their angles is 180 degrees
<A + <B = 180
20+x + 10+2x = 180
30+3x = 180
3x = 180-30
3x = 150
x = 150/3
x = 50 degrees
Hence the value of x is 50 degrees

Find the value of each trigonometric ratio. For example answer "2/3".
Answer:
The value of sin X = 12 / 13
Step-by-step explanation:
Given
The angle ∠XThe side opposite to angle ∠X = 12The hypotenuse = 13To determine
sin X = ?
We know that the trigonometric ratio involving sin Ф such as
sin Ф = opposite / hypotenuse
Here:
Ф = Angle XThe side opposite of Angle X = 12Hypotenuse = 15so substituting Ф = X, opposite = 12 and hypotenuse = 13 in the equation
sin Ф = opposite / hypotenuse
sin X = 12 / 13
Therefore, the value of sin X = 12 / 13

A rental truck costs $96 per day plus $0.60 per each mile. If Calvin can spend a maximum of $120, how many miles can he drive the rental truck?
Cost of renting a truck for one day = $96
Money Calvin can spend = $120
Money left with Calvin after he spends on the daily rent :
[tex] = \tt120 - 96[/tex]
[tex] = \tt\$ 24[/tex]
Cost charged per mile = 0.60
Number of miles he can drive the rental truck :
[tex] =\tt 24 \div 0.60[/tex]
[tex] = \color{plum}\tt40 \: \: miles[/tex]
Thus, number of miles he can run the truck = 40 miles
Therefore, Calvin can run the truck for 40 miles after he pays the daily fee.
