the correct answer is,
if you want me to solve without the parentheses then the answer would be,
Answer:
A function is a function that passes the vertical line test
Step-by-step explanation:
the vertical line test direction:
draw a line straight down you graph if it hits the x axis two time it not a function
Answer:
12 white 28 printed
Step-by-step explanation:
x = white y = printed
x + y = 40————(1)
4.95x + 7.95y = 282————(2)
Solve for x using 1st equation
x = 40 - y Plug in for x using 2nd equation
4.95(40 - y) + 7.95y = 282 Solve for y
198 - 4.95y + 7.95y = 282
3y = 84
y = 28 Plug in for y using 1st equation
x + (28) = 40 Solve for x
x = 12
I hope this helped and please mark me as brainliest!
Answer:
a represents the Number of Minutes Late, (a=15 in this case)
Step-by-step explanation:
If the daycare charges a base fee of $3 plus $0.50 per minute late for late pickups(after closing time).
Albin on arrival for pickup had to pay $10.50;
She uses the equation
10.50=0.50a+3
0.50a=10.50-3
0.50a=7.50
a=7.50/0.5
a= 15
It means Albin was 15 minutes late to a pickup.
For the red line, we have:
gradient (
) = 1/3
y-intercept = 3
Equation of straight line is given by
, where
is the gradient and
is where the line intercept the y-axis
So we have,
The shaded part is above the line, hence the first inequality is
The black line, we have
gradient,
= 3
y-intercept = -2
, rearranging gives
The shaded region is to the right of the line, hence the inequality is
Note: The first option should be the correct answer but the inequality sign for <span>y > 1/3x + 3 should be </span>
