Answer:
0, 16
1, 15
2, 14
3, 13
4, 12
5, 11
6, 10
7, 9
8, 8
Step-by-step explanation:
Any two numbers that have the product of positive 16 have a geometric mean of 4.
Step-by-step explanation:
To do this, we will substitute the x values to their corresponding equations,
1)
Given 2x + 15 = 19
Calculated 2x + 15 = 19
Given = Calculated, this solution is correct.
2)
Given 3 + x + 2 - x = 16
Calculated 3 + x + 2 - x = 5
Given not equal to calculated, this solution is incorrect.
3)
Given (x+2)/5 = 2
Calculated (x+2)/5 = 2
Given = Calculated, this solution is correct.
4)
Given 2x - 8 = 6
Calculated 2x - 8 = 6
Given = Calculated, this solution is correct.
5)
Given 1/3x + 5 = 14
Calculated 1/3x + 5 = 11
Given not equal to Calculated, this solution is not correct.
Therefore the Correct solutions are 1,3 and 4.
Step-by-step explanation:
S is equal to Q
Q= 48.5
there are two angels (S,Q). They equal 48.5
so 48.5x2= 97
all angels together (QRSP) equals 360
you can take the 97 and subtract it from the 360 =263
divide 263 to get the angels for P and R
S= 48.5
Q=48.5
R=131.5
P=131.5
Answer:
y = 2x-17
Step-by-step explanation:
We have a point and a slope, we can write the equation in point slope form and then convert to slope intercept form
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
y-1 = 2(x-9)
Distribute
y-1=2x-18
Add 1 to each side
y-1+1 = 2x-18+1
y = 2x-17
This is slope intercept form
To complete the square you need to halve the linear coefficient -4/2, square it, 4, and add that value, giving you:
x^2-4x+4 and that is a perfect square equal to:
(x-2)^2
