Answer: x=3
First you cross multiply
Next you swap sides then divide both sides by 4
Answer:
y= -5x +7
Step-by-step explanation:
We can see points on the graph:
The function in general form is:
Let's find the slope and y-intercept as per identified points on the graph:
b= y- mx
- b= - 3 -(-5)*2= -3 +10= 7
Based on the found values of m and b, the given line is:
Answer: In right triangle XZW, the height WY is the geometric mean of segments ZY and XY.
Hence,
4^2=3 x a,
a=16/3 un.
None of the answers are correct
(x+3)^2 + 10 first you factor out the (x+3)
(x+3)(x+3) + 10
x^2 + 6x + 9 +10 simplify
x^2 + 6x + 19
Answer:
15 ft
Step-by-step explanation:
We can use the properties of similar triangles.
16/8 = 30/x
2 = 30/x Multiply each side by x
2x = 30 Divide each side by 2
x = 15 ft
The shadow is 15 ft long.
Check:
16/8 = 30/15
2 = 2
