x(t) = 20t
y(t) = 40t - 5t^2
Since we are only interested in comparing the two at time t = 5 seconds, we plug in 5 everywhere we see the variable t and then compare x and y
x(5) = 20(5) becomes x(5) = 100
y(5) = 40(5) - 5(5)^2 becomes y(5) = 200 - 125 and then y(5) = 75
The ratio of y to x can be expressed as: y/x, so we can say the ratio is equal to 75/100 or 0.75
Answer: 0.75
Answer:
Not right.
Step-by-step explanation:
m <HGJ + m <KGJ =180°
So, m <HGJ = 180° - m <KGJ = 180° - 86° =94°
Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, - 3) ← 2 points on the line
m = 
= 
= - 3
Answer:
no
Step-by-step explanation:
3 is the x coordinate/ integer and -4 is the y coordinate and the integer so it wouldn't make sense
x= 3 is a solution
and id you don't understand the first thing i said watch this
#1. 3, - 4
#2. x= - 4
#3. substitute/replace the x with what the x coordinate is
#4. it will be 3= - 4
#5. as you can see the numbers don't equal each other so it's a no solution
Answer: A y= -4x + 2
Step-by-step explanation:
y= mx + b
when x is 0, y is 2 which you make the y intercept (b) 2
going from x=0 to x=1, the y coordinate moves down 4, so the slope would be -4
