Answer:
2
Step-by-step explanation:
let the number be n , then
7n - 8 = 6 ( add 8 to both sides )
7n = 14 ( divide both sides by 7 )
n = 2
The number is 2
Answer:
81 and 9
Step-by-step explanation:
Okay, so if 2 angles are complementary, it means that when they are added together, they equal 90 degrees. So using this, we can make an equation. Let's call one angle x and the other that is 72 less than angle x can be described as x - 72. Now let's make that into an equation.
90 = x + x -72
So in order to solve this, we need to get x by itself. So we need to add 72 on both sides, and the equation should now look like this:
162 = x + x
Now we have to add the x's together.
162 = 2x
Now in order to isolate x, you divide by 2 on both sides.
X = 81
So we now know the larger angle is 81, and the smaller angle which is 72 less, would be 9.
Answer:
A. y - 3 = -(x + 5)
Step-by-step explanation:
The general formula for point-slope form is:
, where 'm' is the slope and
is a point on the line
Using the given graph, you can see that the line is downhill, indicating a negative slope. Starting at the y-intercept of -2 and going down two and over two to the point (2, -4) tells us the overall slope is '-1'. You can also see that there is a point at (-5, 3) on the graph. Using the slope (-1) and the point (-5, 3):
y - 3 = -1(x + 5)
I believe about 750 this is because of you multiply 150 and 5 you get your answer 750 because each 2 minutes she types is 150 and although you can find your average I just add the average 5 times this would be an easier way!!!
