Which expression is the factorization of x^2+10x+21?
Answer:
To factor a trinomial in the form Ax^2 + Bx + C when the A = 1. You need to find the factors of C that when added or subtracted will give you B.
Factors of 21 are either 1,21 or 3,7. Since +3 and +7 will give you 10 then those will be the two factors you will use.
Factoring x^2+10x+21 will give you (x+3)(x+7)
Step-by-step explanation:
Answer:
(x+3)(x+7)

Which set of values makes the inequality n > -5 true?
A
{-5, -5.5, -6}
B
{-5, -4.5, -3}
С
{-6,0,5}
D
{-6, -7,-8}
Answer:
B
Step-by-step explanation:
≥ means that it is greater than or equal to.
Any set that has all numbers over or equal to -5 would be correct, meaning that -5, -4.5, and -3 would be correct.
Hope this helps. Have a nice day.
Inequalities help us to compare two unequal expressions. The set of values makes the inequality n > -5 true is {-5, -4.5, -3}.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
As we need to find the values that will satisfy the inequality n≥-5, therefore, we need values that are greater than or equal to -5.
Hence, the set of values makes the inequality n > -5 true is {-5, -4.5, -3}.

10x - 12y = 22
5x - 6y = 11 elimanation
Answer:
This is an identity or infinite solutions
Step-by-step explanation:
10x - 12y = 22
5x - 6y = 11
-2(5x - 6y = 11 )
-10x + 12y = -22
10x - 12y = 22
0=0
Identity solution
Answer:
2(5x - 6y = 11)= 10x - 12y = 22 so they are the same equation

Find the number of sides of a regular polygon if one interior angle is 120 degrees A3 B4 C5 D6
Answer:
n = 6
Step-by-step explanation
Number of sides = 360/Measure of exterior
Measure of exterior = 180 - interior angle
Exterior angle = 180 - 120
Exterior angle = 60 degrees
Substitute into the formula
number of sides = 360/60
number of sides = 6
Hence the number of sides required is 6
It takes a new mail carrier 4 hours to deliver the mail on route a. It takes an experienced mail carrier 3 hours to do the same job. How long would it take if they worked together?
Answer: [tex]\frac{12}{7}\ \text{hours}[/tex]
Step-by-step explanation:
Given
New mail carrier takes 4 hours for delivery i.e.
New mail carrier completes [tex]\frac{1}{4}[/tex] part of work in 1 hour
Old mail carrier takes 3 hours for delivery i.e.
mail carrier completes [tex]\frac{1}{3}[/tex] part of work in 1 hour
If they work together, they complete the work in x hours i.e.
[tex]\Rightarrow \dfrac{1}{x}=\dfrac{1}{4}+\dfrac{1}{3}\\\Rightarrow \dfrac{1}{x}=\dfrac{3+4}{12}\\\Rightarrow x=\dfrac{12}{7}\ \text{hours}[/tex]
. Find f(3) for the following function
[tex]f(x)=3(2)^x+6[/tex]
a.f(3) = 222
b.f(3) = 9
c.f(3) = 24
d.f(3) = 30
Answer:
[tex]\boxed {\boxed {\sf D. \ f(3)= 30}}[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)= 3(2)^x+6[/tex]
We want to find f(3), so we must substitute 3 in for x.
[tex]f(3)= 3(2)^3+6[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve the exponent first.
2³= 2*2*2= 4*2= 8[tex]f(3)= 3(8)+6[/tex]
Multiply 8 and 3.
[tex]f(3)= 24+6[/tex]
Add.
[tex]f(3)=30[/tex]
For the function given, f(3) is 30.

Which of the following expressions are equivalent to -4/7 - 8/9 + 4/7 + 9/8?
Answer:
C and D
Step-by-step explanation:
I'm too braindead to explain this, read comments
Answer:
-2 1/72
Step-by-step explanation:
Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.

Jerry played with 333 friends today, all at different times. He played with Tommy for 1\dfrac{7}{8}1 8 7 1, start fraction, 7, divided by, 8, end fraction hours, then Nathan for 1\dfrac{3}{4}1 4 3 1, start fraction, 3, divided by, 4, end fraction hours, then Chris for \dfrac{3}{2} 2 3 start fraction, 3, divided by, 2, end fraction hours. How many hours did Jerry play with his 333 friends today?
Answer:
8 1/8 hours
Step-by-step explanation:
Jerry played with 3 friends today, all at different times.
Tommy = 1 7/8 hours
Nathan = 1 3/4 hours
Chris = 3 3/2 hours
How many hours did Jerry play with his 3 friends today?
Number of hours Jerry play with his 3 friends today = 1 7/8 + 1 3/4 + 3 3/2
= 15/8 + 7/4 + 9/2
= (15+14+36)/8
= 65/8
= 8 1/8 hours
