Answer:
x=3
Step-by-step explanation:
The way you find x-intercepts is by setting y equal to 0. So then you just solve for x.
(0)-12=-2(x+3)-2(0)
-12= -2x -6 -0
-12 = -2x -6
-6 = -2x
x = 3
Hope this helped.
Answer:
In triangle DEF:
Given: 
, 
and 
To list the sides of a triangle in order from shortest to longest.
In the Figure as shown below :
If one of the angle of a triangle is larger than, then the sides opposite the larger angle is longer than the side opposite to the shorter
Therefore, the list of the sides of a triangle DEF in order from shortest to longest is,
Answer:
the real solutions are the ones that actually cross the x-axis.
so the real solutions are (-5, 0) (-1,0) (4,0) and (8,0)
Answer:
d. She should reject the null hypothesis because p < 0.10.
Step-by-step explanation:
We have a t statistic, so let's solve for the P-value on our calculators. (tcdf on a TI-84 calculator is 2nd->VARS->6.)
tcdf(left bound, right bound, degrees of freedom)
- Our left bound is t=1.457.
- Our right bound is infinity, because we're interested in the hypothesis µ>40 mg/dL. We use 999 to represent infinity in the calculator.
- Our degrees of freedom is n-1 = 15-1 = 14.
tcdf(1.457,999,14) = .084
.084 < P-value of .10, so we reject the null hypothesis.
