At a concert 20% of the audience members were teenagers. If there were 1800 people at the concert, how many of those people were teenagers ?
Answer:
360 of the people were teenagers
Step-by-step explanation:
To find percentages you need to divide the number by 100
∴ 20% of 1800
=20 ÷ 100 ×1800
=360
∴ there were 360 teenagers at the concert.

A line passes through the points (3,16) and (6,19). Write a linear function rule in terms of x and y for this line.
Answer:
y=1x+13
Step-by-step explanation:
First find the slope of the line. Slope is (y2-y1)/(x2-x1). Plug in 19 for y2, 16 for y1, 6 for x2, 3 for x1. So (19-16)/(6-3) is 3/3 or 1. The slope of the line is 1.
take the equation y=mx+b and plug 1 in for the slope (m). Then plug in one set of points. Using (3,16) into y=1x+b, 16=1(3) + b. Solve for b. B is 13. So the linear equation is y=1x+13.

Step-by-step explanation:
Although, the area will be multiplied by 4.
For example, if the side values are 2,
The area is 4.
But if we enlarge it by a scale factor of two, the side values will be 4.
The area will be 16.

Which of the following is a factor of the expression 4x^2-2x-42?
Group of answer choices
2x-6
2x-7
x-3
4x-7
Answer:
[tex]4x ^{2} - 2x - 42 \\ 2(2 {x}^{2} - x - 21) \\ 2(2 {x}^{2} + 6x - 7x - 21) \\ 2(2x(x + 3) - 7(x + 3) \\ 2(2x - 7)(x + 3)[/tex]
Answer:
2x - 7
Step-by-step explanation:
4x² - 2x - 42 ( factor out 2 from each term )
= 2(2x² - x - 21) ← factor the quadratic
consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 21 = - 42 and sum = - 1
the factors are+ 6 and - 7
use these factors to split the x- term
2x² + 6x - 7x - 21 ( factor the first/second and third/fourth terms )
= 2x(x + 3) - 7(x + 3) ← factor out (x + 3) from each term
= (x + 3)(2x - 7)
then
4x² - 2x - 42 = 2(x + 3)(2x - 7) ← in factored form
with 2x - 7 as a factor
I need help with 2(4/3)x8x15+280919 we couldn’t use calculator
Answer:
281,319.005
Step-by-step explanation:
Because 2 and 4/3=3 and 1/3
Because since the numerator= 4 and the denomeyer is 3 we can add another whole number so 2 and 4/3 can add whole so 2 + 1=3 wholes with 1 left over so 3 1/3.
Next we do 3 1/3 x 8 which=26.667 also known as 26 2/3
Because 2/3=66.667.
Next we so 26 and 2/3 x 15=400.005
And last 400.005 + 280,919=281,319.005

Your teacher announced a 50-point math quiz for tomorrow. The quiz will have 15 questions with word problems worth 4 points each and some open response questions worth 3 points each. Find the number of each type of question. You may use any of the methods to solve. Check your answer.
Answer:
5 word problems(4points each) & 10 open (3 points each)
Step-by-step explanation:
O= open response
W= word problems
W+O =15
4W + 3O = 50
multiply the first by -3 to eliminate O
-3W -3O = -45
4W + 3O = 50
AD BOTH
W = 5 ( 5 questions word problems)
O= 10 ( 10 questions open response)

What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
Answer:
x + 6
Step-by-step explanation:
Edit:
A moderator mentioned my answer had a mistake: turned out the question posted was incomplete. The complete question should read:
"
What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
x – 6
x – 3
x + 1
x + 6
"
As shown in the same graph, f(x) cross the x-axis at x = -6, -3 and 0.
When a polynomial crosses the x-axis at x = a, (x - a) must be a factor.
So (x + 6), (x + 3) and x are factors of f(x).
Of the options, the correct answer is x + 6.
