Marc is 12
Using david’s age we can find what marc’s age is from three years ago by working backwards.
26-8= 18
18/2 = 9
Three years ago marc was 9 so now he is 12 (since 9+3 = 12)
Answer:
3 + 0.8 + 0.03 + 0.005
Step-by-step explanation:
Expand the number. Set each non-zero digit by itself:
3.835 = 3 + 0.8 + 0.03 + 0.005
3 + 0.8 + 0.03 + 0.005 is your answer.

Answer:
1 Milk = 1.5 Chocolate syrup
Step-by-step explanation:
3 ÷ 2 = 1.5
12 ÷ 8 = 1.5
3/2 ÷ 1 = 1.5
15 ÷ 10 = 1.5
Use two point form to find the equation of the line that goes through those two points
y-8/14-8=x-1/3-1
Simplify to get y=3x+5 and the slope of this line is 3
Since the line is parallel, they have the same slopes.
So the equation is y=3x+9
Answer:
f(x)=(x-5)(x-7)
(x-6)²-1²
Step-by-step explanation:
Given:
Equation:
f(x)=x²-12x+35
Find:
Factories
Vertex form
Computation:
Factories
f(x)=x²-12x+35
f(x)=x²-(5+7)x+35
f(x)=x²-5x-7x+35
f(x)=x(x-5)-7(x-5)
f(x)=(x-5)(x-7)
So,
x = 5 , x = 7
Vertex form
By middle term divide by 2
12/2 = 6
So,
x²-12x+6²+35-6²
(x-6)²-1²
