Answer:
180°
Step-by-step explanation:
Since a sprinkler rotates 90°, pauses,and then rotates another 90°
So, here total degrees be like
= 90° + 90°
= 180°
hence, The number of degrees did it rotate altogether should be considered as the 180 degrees.
Answer: It only has one solution.
Step-by-step explanation:
Let's solve your equation step-by-step.
3(
7
/3
+
4
/3
)−2x+8=5x+12
Step 1: Simplify both sides of the equation.
3(
7
/3
+
4
/3
)−2x+8=5x+12
11+−2x+8=5x+12
(−2x)+(11+8)=5x+12(Combine Like Terms)
−2x+19=5x+12
−2x+19=5x+12
Step 2: Subtract 5x from both sides.
−2x+19−5x=5x+12−5x
−7x+19=12
Step 3: Subtract 19 from both sides.
−7x+19−19=12−19
−7x=−7
Step 4: Divide both sides by -7.
−7x

Answer:
y = 2/3x - 1
Step-by-step explanation:
Find the slope:
2y = 3x - 5
2/2y = 3/2x - 5/2
y = 3/2x - 5/2
Slope is 3/2
In order for a line to be perpendicular the slope in the equation should be flipped. 3/2 becomes 2/3.
Perpendicular equation:
y = 2/3x + b
b is going to be equal to the y intercept of the point they gave us, so -1.
Answer: y = 2/3x - 1
