Hi there,
Question: Need to Solve for y.
8×+9y=-5
-8×-9y=5
Answer:
8 × +9y = -5
Solve your equation in steps:
(8)(9)y = -5
Step 1: Simplify both sides of the equation
72y = -5
Step 2: Divide both sides by 72
72y/72 = -5/72y
Then when your done, you get your answer y= -5/72
Answer:
-8 × -9y = 5
Solve your equation in steps:
((-8)(-9))(y) = 5
Step 1: Simplify both sides of the equation.
72y = 5
Step 2: Divide both sides by 72.
72y/72 = 5/72
Then when your done, you get your answer y= 5/72
So here is the answers for both math problems.
8 × +9y = -5 is y= -5/72
-8 × -9y = 5 is y= 5/72
Hope this helps!
Part a: The value of x is 33°
Part b: The measure of each base angle is 69°
Explanation:
It is given that the vertex angle of an isosceles triangle measures 42°.
The base angle in the triangle has a measure of 
Part a: To determine the value of x
Since, in an isosceles triangle the base angles are always equal.
Thus, the three angles in an isosceles triangle add up to 180°
Hence, we have,





Thus, the value of x is 33°
Part b: To find the measure of each base angle.
Base angle = 
Substituting
, we get,



Thus, the measure of each base angle is 69°
Answer:
9.385 km
Step-by-step explanation:
Given the points :
home (1 -3) school (-1, 2) library (3, 2)
Distance between Home and school :
Distance = √(x2 - x1)² + (y2 - y1)²
Home = (1, - 3) ; School = (-1, 2)
x1 = 1 ; y1 = - 3 ; x2 = - 1 ; y2 = 2
Distance = √(-1 - 1)² + (2 - (-3))²
Distance = √-2² + 5²
Distance = √4 + 25
= 5.385 km
From school to library :
School = (-1, 2) ; library (3, 2)
x1 = - 1 ; y1 = 2 ; x2 = 3 ; y2 = 2
Distance = √(x2 - x1)² + (y2 - y1)²
Distance = √(3 - (-1))² + (2 - 2)²
Distance = √4² + 0²
Distance = √16 + 0
Distance = √16
Distance = 4 km
Total distance in kilometers from home to library :
(5.385 + 4) km = 9.385km
97 I believe
Hope this helps
