Answer: x=13
Step-by-step explanation: ?+?=35
(2x-4)+x=35
3x-4=35
3x=35+4
3x=39
x=13
Answer:
m = 3, n = -2.
Step-by-step explanation:
Substitute n = 3m - 11 in the second equation:
2m + 3(3m - 11) = 0
2m + 9m - 33 = 0
11m = 33
m = 3.
Substitute for m in n = 3m-11:
n = 3(3) - 11
n = -2.
Answer:
12
Step-by-step explanation:
(12-9)(8)/2=12
Answer:
PS=5.4
Step-by-step explanation:
The centroid divides each median in the ratio 2:1
If U is the centroid, then
We use ratio to obtain;
Cross multiply;
Expand;
Group similar terms;
x=1
PS=PU+US
PS=3.6+1+0.8
PS=3.6+1+0.8
PS=5.4
Answer:
g(x) = x² - 8
g(x) = 1(x-0)² - 8
Step-by-step explanation:
f(x) = x²
we translate this parent function 8 units down thus:
g(x) = f(x) - 8
g(x) = x² - 8
in the form a( x - h)² + k:
g(x) = 1(x-0) - 8
k = (-8)
As the change is constant rather than the variable of the quantity of "x" It is a movement of the whole f(x) function eight units down.
h = 0
Because, there is no information about a stretchment of the parent function in g(x)
