Answer:
The answer is 7
Step-by-step explanation:
2x+17+3x=4x+3x+3
5x+17=7x+3
5x-7x=3-17
-2x=-14
x=7
Answer:
f(0) = 1
Step-by-step explanation:
f(x) indicates the "output" value present at the "input" (Output referring to the y value and input referring to the x value). So f(0) would mean the "y" value present at x = 0; however, there are two circles at x = 0. One of the dots is open(hollow) meaning that the "x" and "y" values present there are excluded. This leaves the closed(filled) dot which means that value is included and is the answer.
Answer:
they are congruent so e=44°
Step-by-step explanation:
Given:
To find:
The values of x.
Solution:
We have,
(Distributive property)
(Combining like terms)
Add 28 on both sides.
Subtract 10x from both sides.
Divide both sides by 14.
Therefore, the values of x are all real numbers less than 2, i.e., x<2 .
Answer:
9x² - 7x - 9
Step-by-step explanation:
Two sides
(6x + 7) + 8x = 14x + 7
total perimeter - two sides = Third side
9x² + 7x - 2
- (14x + 7)
––––––––––
9x² - 7x - 9
