Answer:
Step-by-step explanation:
To find the slope of the equation use 
.
So, 
= 
. Now we can use our slope and any of the two points to write in point-slope form, which is 
. Using the point (7,-6), the formula will give .
To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.
The answer is <span>$103.
To determine </span><span> how much Eileen will spend on gasoline, first we need to calculate how many gallons she needs.
If she drives 850 miles and </span><span>her car gets 23 miles per gallon, we can use the proportion:
850 miles : x gallons = 23 miles : 1 gallon
Crossing the products:
x = 850 miles </span>× 1 gallon ÷ 23 miles
x = 36.96 gallons
Thus, Eileen needs 36.96 gallons of gas. If the cost per gallon of gas is$2.79, using the proportion:
36.96 gallons : x = 1 gallon : <span>$2.79
x = 36.96 gallons </span>× $2.79 <span>÷ 1 gallon
x = </span>$103.12
x ≈ $<span>103</span>
Answer:
Step-by-step explanation:
Let
We factor 2 to obtain;
We factor the polynomial within the parenthesis by grouping.
We apply difference of two squares on the second factor: 
We now compare to;
It is now obvious that

What are the angles?
if all of them are below 90 degrees, it is acute.
if one angle is 90 degress, it is right
if one angle is more than 90 degrees, it is obtuse
