Answer:
1) Lowest temperature = -5.5 (Wednesday)
2) a. -62 is less than (colder than) -55 so the average temperature on Mars is warmer.
b. -62 < -55
3) No. -14 means that the number is 14 <u>less than</u> zero. -21 means that the number is 21 <u>less than</u> zero. Also, if you plot these numbers on a number line, -21 will be further to the left than -14. The further to the left a number is, the less it is. So, -21 is less than -14 and Anchorage is colder than Minneapolis.
I don't see "equation 1." Where is it/
Just supposing that "equation 1" were y = 2x - 3.
Then points on the graph would be (-5,-13), (-2,-7), (0, -3), (2, 1) and (5, 7). I got the x-values from the table for equation 1.
Name the first even integer you are looking for

. The next even number is

.
Their sum is

, so

. That means

, hence

.
So, the desired numbers are

and

.

Explanation: 3 x 2 + 10 x + 3 We can Split the Middle Term of this expression to factorise it. In this technique, if we have to factorise an expression like a x 2 + b x + c , we need to think of 2 numbers such that: N 1 ⋅ N 2 = a ⋅ c = 3 ⋅ 3 = 9 and, N 1 + N 2 = b = 10 After trying out a few numbers we get: N 1 = 9 and N 2 = 1 9 ⋅ 1 = 9 , and 9 + ( 1 ) = 10 3 x 2 + 10 x + 3 = 3 x 2 + 9 x + 1 x + 3 = 3 x ( x + 3 ) + 1 ( x + 3 ) ( 3 x + 1 ) ( x + 3 ) is the factorised form for the expression.
