ANSWER
The points (1,2) and (7,2) lie on the given curve.
EXPLANATION
The given parametric equations are:
and
We make t the subject in the first equation to obtain:
We substitute this into the second equation to get:
When x=1,
When x=2
When x=7,
Therefore the points (1,2) and (7,2) lie on the given curve.
Answer:
x = 15
Step-by-step explanation:
I am going to use the "butterfly" method for proportions
(there is another type of butterfly method that is different, I am not sure if there is another name for this method, sorry!)
Multiply the:
- top left by the bottom right
-the top right by the bottom left
and then:
- set them equal to each other
So we will <u>multiply 7 by x and 21 by 5</u> (if this doesn't make sense tell me and I will explain it even more!)
7x = 21 * 5
7x = 105
(Divide both sides by 7) <em>x = 15</em>

Answer:
The answer to your question is in the picture below
Step-by-step explanation:
y + 3/4x < 2
y+ 3/4x = 2
y = -3/4x +2
Interceptions (0,2) and (8/3, 0) It's a dotted line and we are interested in the area below the line
y - 1 ≥ 2x
y - 1 = 2x
y = 2x + 1 Interception, it's not a dotted line with interceptions (0,1) and (-1/2, 0), we are interested in the area up the line.
