Answer:
x = 1
Step-by-step explanation:
3x + 2 = 5
Inverse oeprations
3x + 2 = 5
-2 -2
3x = 3
/3 /3
x = 1
m∠Z = 55°
Solution:
Given m∠A = 75° and m∠B = 50°
Let us first find the m∠C.
Sum of the angles of the triangle is 180°.
In ΔABC,
m∠A + m∠B + m∠C = 180°
⇒ 75° + 50° + m∠C = 180°
⇒ 125° + m∠C = 180°
⇒ m∠C = 180° – 125°
⇒ m∠C = 55°
Given ΔABC ≅ ΔXYZ.
Corresponding parts of congruence triangles are congruent.
⇒ m∠Z = m∠C
⇒ m∠Z = 55°
Hence, m∠Z = 55°.
As we already have the value of y,we can put it into another equation.
Here's how we can solve the equation:
y = 2x+48...(1)
y = 8x...(2)
Put (2) into (1)
(8x) = 2x+48
8x-2x = 48
6x = 48
x = 8...(3)
Put (3) into (1)
y = 8(8)
y = 64
Thus, x=8, y+64
Hope it helps!
Step-by-step explanation:
the slope= (-11+3)/(1+3) = -8/4 = -2
the equation:
y +3 = -2(x+3)
y+3=-2x-6
y= -2x -6-3
y = -2x -9
Answer:
B
Step-by-step explanation:
For x<=0, the equation is 2x+2 and hence option B is the answer.
