Answer:
A'(8, -5)
Step-by-step explanation:
Reflection across the line y=x can be written as the transformation ...
(x, y) ⇒ (y, x) . . . . . . swap the values of x and y
Then point A(-5, 8) will be reflected to ...
A' = (8, -5)
Answer:
C
Step-by-step explanation:
Alright so for this one they want us to find the x values of angle 3 and angle 5 and those 2 angles happen to be supplementary meaning that the two angles will add up to equal 180. So to setup the equation we do
180 = 5x+10+3x+10
step 1 combine like terms ( 5x +3x and 10 + 10)
180 = 8x +20
step 2 subtract each side by 20
160 = 8x
step 3 divide each side by 8
x=20
Answer:
1995
Step-by-step explanation:
Growth of 2.4% means 100+2.4 = 102.4% of the previous
102.4% = 1.024
100,000,000 = 87,000,000 × (1.024^n)
100/87 = 1.024^n
ln(100/87) = nln(1.024)
n = 5.871941941
Almost 6 years later,
1989 + 6 = 1995
2/5m + 7/5 you distribute and add like terms
