Answer:
z = 3
Step-by-step explanation:
Δ UWV and Δ UWX are similar triangles , thus corresponding angles are congruent , that is
∠ UWV = ∠ UWX , substitute values
9z - 24 = z ( subtract z from both sides )
8z - 24 = 0 ( add 24 to both sides )
8z = 24 ( divide both sides by 8 )
z = 3
Answer:
C. When the equations -10x + 5y = -60 and -3x − 5y = -5 are added together, a third linear equation, -13x = -65, is formed, and it shares a common solution with the original equations.
Step-by-step explanation:
2x-y=12
-3x-5y=-5
multiply the first equation by -5
-10x +5y = -60
add the 2 equations together
-3x-5y=-5
-10x +5y = -60
-------------------------
-13x = -65
We use the addition property of equality which says adding the same thing to both sides, doesn't change the equation, so we will get the same answer as the original equation
Answer:
21.98
Step-by-step explanation:
C = Dπ
D = 7
7 * 3.14 = 21.98
Answer: (-∞,∞)
Step-by-step explanation:
f(x)=4x+19
g(x)=12x+14
f + g= 4x +19 + 12x + 14 = 16x + 33
Domain of 16x + 33 = (-∞,∞)
Answer:
X Y
0 5
1 10
2 15
3 20
4 25
8(?) 40
Step-by-step explanation:
The way the first four are constantly moving upwards at a rate of five per 1x makes me think that the last X value could be 8.
