Answer: x=-5
Step-by-step explanation:
Answer:
y = 15x + 200
Step-by-step explanation:
It should be y = 150x + 200 because if you look at the first one, 300x is too big.
You can cross out the last two.
Then you can see the second one also doesn't work.
Cross that one out.
The first choice is the only one.
Okay so the value of X is 9x^2/7
Answer:
Lisa must get an 88.75 or higher to stay in between 80 and 90.
Step-by-step explanation:
Answer:
CD = √11 and CE = √11
Step-by-step explanation:
We know that m∠D is 45° (by using the sum of interior angles in a triangle) so therefore, ΔDCE is a 45 - 45 - 90 triangle (the 45, 45, and 90 refer to the angle measures). The ratio of sides in a 45 - 45 - 90 triangle is 1 : 1 : √2 where the 1s are the sides and the √2 is the hypotenuse. We need to solve for x in x : x : √22. If you notice that √22 = √2 * √11, we can use this to find x, therefore, x = 1 * √11 = √11 so CD = √11 and CE = √11.
