Answers
Answer:
y=50°
Step-by-step explanation:
if all triangles add up to 180° you would subtract the angle you already know(80) from 180 which would be 100°
since there are 2 corners we dont know you would divide by 2 which would be 50°

Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).
Answers
Answer: 147
Step-by-step explanation:
To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).
f(3)=2(3)²-4(3)+9 [exponent]
f(3)=2(9)-4(3)+9 [parenthesis]
f(3)=18-12+9 [subtract]
f(3)=6+9 [add]
f(3)=15
Now, we find f(-3).
f(-3)=2(-3)²-4(-3)+9 [exponent]
f(-3)=2(9)-4(-3)+9 [parenthesis]
f(-3)=18+12+9 [add]
f(-3)=30+9 [add]
f(-3)=39
With the values of f(3) and f(-3), we can evaluate the expression.
2(15)+3(39) [multiply]
30+117 [add]
147
Now, we know the value is 147.

Answers
Explanation:
The two angles shown combine to 180 degrees because the angles form a straight line.
(3x+18)+(4x+15) = 180
7x+33 = 180
7x = 180-33
7x = 147
x = 147/7
x = 21

over $3.00
Choose the correct answer below.
A.
The most reasonable estimate is over $3.00. Since 5% of $60.00 is $4.00, 5% of $62.00 would be greater than $3.00.
B.
The most reasonable estimate is over $3.00. Since 5% of $60.00 is $3.00, 5% of $62.00 would be greater than $3.00.
C.
The most reasonable estimate is under $3.00. Since 5% of $60.00 is $3.00, 5% of $62.00 would be less than $3.00.

The least common multiple of two numbers is 84, and one of the numbers is 5 less than the other number. What are the numbers? Complete the explanation.
The two numbers are __ and __.84 is a multiple of each of its factors. The factors with a difference of 5 are__ and __ their LCM is 84.
Answers
Answer:
factor 1 = x
factor 2 = x - 5
(factor 1) * (factor 2) = 84
(x) * (x - 5) = 84
x² - 5x = 84
x² - 5x - 84 = 0
(x - 12) (x + 7) = 0
x - 12 = 0 or x + 7 = 0
x = 12 or x = -7
factor 2 = x - 5 = (12) - 5 = 7 or (-7) - 5 = -12
Answer: 12, 7 or -7, -12
Answer:
