Given
Monday -7°
Procedure
Tuesday the temperature was cooler
t should be less than -7 e.g. -8, -9, -10
What you do is you distribute the 5.
So your answer would be 5x+15
Answer:
x = 14
Step-by-step explanation:
It's given in the question that a point R lies between the two points Q and S.
Therefore, by addition postulate of segments,
QS = QR + RS
Now we substitute the values of the given segments,
3x - 5 = (35 - x) + (3x - 26)
3x - 5 = -x + 3x + 35 - 26
3x - 5 = 2x + 9
3x - 2x = 5 + 9
x = 14
Therefore, the value of x is 14.
Answer:
- 3 and x² + 2x - 3
Step-by-step explanation:
(a)
To evaluate g(1) substitute x = 1 into g(x)
g(1) = 1² - 4 = 1 - 4 = - 3
(b)
Substitute x = x + 1 into g(x)
g(x + 1) = (x + 1)² - 4 ← expand parenthesis using FOI
= x² + 2x + 1 - 4 ← collect like terms
= x² + 2x - 3
You can write an equivalent expression with this knowledge by taking a two numbers, and multiplying both of them by a number. You can extract the number by taking the gcf of both of them, and dividing them both by it and putting the numbers in a parenthesis and multiplying the numbers by the gcf.<span />
