Answer:
x = 12
Step-by-step explanation:
Δ ESR and Δ EGF are similar, then ratios of corresponding sides are equal, so
= 
, substitute values
= 
( cross- multiply )
55(12x - 3) = 6435 ( divide both sides by 55 )
12x - 3 = 117 ( add 3 to both sides )
12x = 120 ( divide both sides by 12 )
x = 10
Answer:
2/3 min
Step-by-step explanation:
We can write these as equations
so 8-2.5x=5-0.5x
We isolate x by subtracting both sides by 5
3-2.5x=0.5x
add 2.5x to both sides
3=2x
divide both sides by 2
x=2/3min
(plz give brainliest)
10 : 30
4: x [x is the length]
10/4=2.5
30/2.5=x=12
length of the diagram is 12cm
Answer:
B)
Step-by-step explanation:
A function is when every input has one output.
Easiest way is to do the "vertical line test" and "horizonal line test."
Basically you draw a vertical line and a horizontal line.
If either line passes through more than one point, then it is not a function.
The only one that passes them is B, the line.
Answer:
Step-by-step explanation:
The given function is
Let
Interchange x and y.
Solve for y,
Divide both sides by 2
Therefore;
