First, subtract 7 on both sides. Now, you have 4x<1. Divide by 4 on both sides. Finally, you get x<1/4 (a quarter or said as one-fourth). So, x<1/4.
Answer:
Sam is incorrect.
Step-by-step explanation:
Using Pythagorean Theorem, we can find the length of diagonal SQ as 13.4 (6^2 + 12^2 = c^2, 36 + 144 = c^2, sqrt(180) = c, c is approx 13.4). We can do the same for diagonal OM (6^2 + 6^2 = c^2, 36 + 36 = c^2, 72 = c^2, sqrt(72) = c, c is approx 8.5). Sam is therefore incorrect because 13.4 is not double of 8.5.
Answer:
x = 3 - t and y = 4 - 2t
Step-by-step explanation:
We have to find such a set of parametric equations for the given equation which result in an x-value equal to 3 and a y-value equal to 4 when t is substituted as 0.
There can be more than 1 possible answers to this problem. You have to use hit and trial method to come up with the correct set of parametric equations. One of the possible set is:
y = 4 - 2t , x = 3 - t
For t = 0
x= 3 and y = 4
Hence, the condition is satisfied.
Now checking if these parametric equations result in given equation or not.
From second equation, we get:
t = 3 - x
Using this value in first equation, we get:
y = 4 - 2(3 - x)
y = 4 - 6 + 2x
y = 2x - 2
Which is the given equation.
Hence the set of parametric equation is:
x = 3 - t and y = 4 - 2t
Answer:
-147
Step-by-step explanation:
(21) • (-7)
Since it’s a positive times a negative, the answer will be negative
-147
