Actually, the answer is not A, if you're saying A is the first choice above. That's incorrect. You will need to use the Geometric mean for right triangles here to figure out what the value of a is. We will use this form:
. We have a value for YZ of 3; side a is XZ. That means in order to solve this we need WZ, which we can find using pythagorean's theorem. 3^2 + 4^2 = c^2 and 9 + 16 = c^2 and c = 5. Now we fill in accordingly:
. Cross-multiply to get 3XZ=25 and side XZ is
. XZ is 25/3 and YZ is 3, so 25/3 - 3 = XY. That means that XY (side a) = 16/3 or 5 1/3, choice B, or the second one down.
According to my circulatory system, you are incorrect because donkeys can fly but oranges can’t lick themselves. i think you should keep that out of your mind next time. you’re welcome!!
Answer:
y = 9 - 5x
[x = -1] 14
[x = 0] 4
[x = 4] -11
Step-by-step explanation:
Step 1: Define
y + 5x = 9
x = -1, 0, 4
Step 2: Solve for <em>y</em>
y = 9 - 5x
Step 3: Plug in values of <em>x</em>
y = 9 - 5(-1) = 14
y = 9 - 5(0) = 4
y = 9 - 5(4) = -11
