Answer:
He was 11
Step-by-step explanation:
if Camila was 4 years younger than her brother and she was seven. That means he is 4 years older than her. so 7+4=11
Answer:
There is a horizontal translation 4 units left, and and vertical translation 1 unit down.
Step-by-step explanation:
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Parent function: f(x) = (5)^x
Horizontal translation: 4 units left
Vertical translation: 1 unit down
Reflection about the x-axis: none
Vertical stretch: stretched
Answer:
(x+5)(x+4)
Step-by-step explanation:
x^2+9x+20
Factor
What 2 numbers multiply to 20 and add to 9
5*4 = 20
5+4 =9
(x+5)(x+4)
I'm pretty sure you can only do it by calculator
Press the SIN button, open parentheses, 180, close parentheses,
And hit enter
Hope this helps :)
Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = 
= 3 , then
y = 3x ← is the equation of the graphed line
