Answer:
"a" must be negative
Step-by-step explanation:
The slope between points (-1, 1) and (1, -1) is a minimum of (-1-1)/(1-(-1)) = -1.
The slope between points (1, -1 and (3, -4) is a maximum of (-4-(-1))/(3-1) = -3/2.
Thus, as x increases, the slope is decreasing. In order for that to be the case, the value of <em>a</em> must satisfy a < 0.
The first two rows of coefficients are identical, so by inspection, the determinant is 0.
Answer:
1. 90-68= 22
2. 90-80= 10
3. 90-3= 87
Step-by-step explanation:
A complement angle is found by their sum being 90 degrees. So, you are looking for the angle that would add to the given angle to = 90.
Let's take a look at the exponent rule:
Her mistake was she multiplied the exponents instead of adding it up.
Answer:
w + 2.3 > 18
Step-by-step explanation:
If I'm assuming this correctly, then it should be that w, added by 2.3, will be <u>Greater Than</u> 18.
