What are the solutions to the quadratic equation 0=(x−4)(x+2)?
Select all that apply.
x=2
x=−2
x=−4
x=0
x=4
Answer:
x = 4,
x = -2
Step-by-step explanation:
( x - 4 ) ( x + 2 ) = 0
Find out when the equation is 0,
When x = 4,
substitute in 4 for x,
( 4 - 4 ) ( 4 + 2 ) = 0
(0) ( 6) = 0 (any number multiplied by 0 is 0).
When x = -2
Substitue in -2 for x,
( -2 - 4 ) ( -2 + 2 ) = 0
(-6) (0) = 0 (again, any number multiplied by 0 is 0).
What is the equation of this line?

The price of the original shirt is $45, it is reduced to $32.50. Calculate the percentage decrease. Show your workings.
Answer:
The percent decrease in the price of shirt is 27.78%
Step-by-step explanation:
The percent decrease is the decrease in the price of a product or good.
Given
Original Price = $45
Decreased price = $32.50
Percentage decrease is calculated by using the formula
[tex]Percentage\ decrease = \frac{decrease}{Original\ price} *100\\[/tex]
And the decrease is calculated as:
[tex]Decrease = Original\ price - Reduced\ price[/tex]
So,
[tex]Decrease = 45-32.50 = 12.5[/tex]
Putting the values in the formula for percent decrease
[tex]Percent\ decrease = \frac{12.50}{45} *100\\=0.2777..*100\\= 27.77..[/tex]
Rounding off to nearest hundredth: 27.78%
Hence
The percent decrease in the price of shirt is 27.78%

(b − 1)² + a^2 ; use a = 6, and b = 1
Answer: The answer is 36
Step-by-step explanation:
*All you have to do is plug those values for A and B so we put 6 for a and b Is 1*
(1-1)^2 + 6^2
1-1 is 0 and 0^2 is 0
6^2 is 36 because 6*6 is 36
What are the solutions to the equation? x2(x+2)(x+6)=0
Answer:
x1 = -6, x2 = -2

The number of pens sold on Monday, p, increased 45% on Tuesday. The expression p+0.45p represents the number of pens sold on Tuesday. What is another expression that can be used to find the number of pens, p, sold on Tuesday?
Answer:
1.45p
Step-by-step explanation:
Here, we want to write another expression other than what we have already to represent a 45% increase in the number of pens sold
We simply find 45% of the number of pens sold the previous day
Mathematically, that would be
45/100 * p = 0.45p
we now add this to the sales made the previous day
= p + 0.45p
if we finally add both, we will have p(1 + 0.45)
= 1.45p

Enter the equation of the line in slope-intercept form.
Slope is 5, and (3, 1) is on the line.
The equation of the line is y
Answer:
y = 5x-14
Step-by-step explanation:
We should use point-slope form to form our equation:
y-1 = 5(x-3)
y-1 = 5x-15
y = 5x-14
Our equation is now in slope-intercept form.

What is the probability of picking an odd number?
Write your answer as a fraction in simplest form
? ?
There is no way to make this fraction any simpler, hence the solution is: 6/11 as to calculate the likelihood of selecting an odd number.
what is fraction ?Mathematical representations of a portion of an entire amount or a ratio between two values are called fractions. It is a means to divide a quantity into equal halves and represent it as a figure that is not always an integer. A vertical or oblique line separating two numbers designates a fraction. The denominator is the value below the line, and the numerator is the number above it. The total number of components in the whole is represented by the denominator, while the numerator is the total number of elements that are being taken into account. For instance, the fraction 3/4 denotes three of every four equally-sized components of a whole.
given
There are a total of 11 balls in the bag, with 6 odd-numbered balls (1, 3, 5, 7, 9, and 11).
In order to calculate the likelihood of selecting an odd number, divide the total number of balls by the number of odd-numbered balls.

the simple interest on a certain sum of money for 2(1/2) years at 12% per annum is Rs.40
Step-by-step explanation:
[tex] si = p \times \frac{r}{100} \times t[/tex]
[tex]si = 40 \times \frac{12}{100} \times \frac{5}{2}[/tex]
[tex]si = \frac{40 \times 12 \times 5}{100 \times 2} [/tex]
[tex]si = \frac{4 \times 12 \times 5}{10 \times 2} [/tex]
