Answer:
It is C
Step-by-step explanation:
Because no functions have 2 numbers that are the same in the x axis or in the input
ans
here let mary age be x and fred be y
1st equation
x= 5y
2nd equation
x+3 =4(y+3)
now from 1st equation putting value of x in equation 2
x+3 = 4y+12
5y+3 = 4y +12
y = 9
so fred is 9 and mary is 45
Answer:
pq = 7
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = p(5, 4) and (x₂, y₂ ) = q(- 2, 4)
pq = 
= 
= 
= 7
Answer:
42° and 48°
Step-by-step explanation:
Complementary angles sum to 90°, hence
x + 10 + x + 4 = 90
2x + 14 = 90 ( subtract 14 from both sides )
2x = 76 ( divide both sides by 2 )
x = 38
x + 10 = 38 + 10 = 48° and x + 4 = 38 + 4 = 42°
3 and 1 over 10 becasue 10 goes into 30 3 times
