Y=145, I’m not sure about X
Answer:
∠ C = 58°
Step-by-step explanation:
DB is a perpendicular bisector , so
∠ ADC = 2 × 32° = 64°
Since AD = CD then Δ ACD is isosceles with the base angle congruent , then
∠ C = 
= 
= 58°
Answer:
24
Step-by-step explanation:
20 percent of 30 is 6
30-6=24
therefore david has 24 sweets left
The equation youre using is y=mx+b
b is the y int which 3 and the slope between the points is 5/2 so your equation is y=5/2x+3
Answer:
You already have what you are going to substitute, just put the y values from the first equation into the second! Like this:
6x - 5(-2x - 9) = -19
Multiply it out:
6x +10x +45 = -19
Add like terms + simplify:
16x + 45 = -19
16x = -64
x = -4
take that x and put it back into the first equation!!
y = -2(-4) -9
y= 8-9
y= -1
so... your answer is (-4, -1)
hope this helps!
