Solve the following quadratic function

Mathematics
1 answer:
Leya [2.2K]2 years ago

Answer:

x = ± 10

Step-by-step explanation:

to solve the equation let y = 0 , that is

100 - x² = 0 ( add x² to both sides )

100 = x² ( take square root of both sides )

± \sqrt{100} = x , that is

x = ± 10

Triangle XYZ is reflected across the y-axis, and X = (4,-5). What are the coordinates of X’ ?
adelina 88 [10]
The correct answer is B.

You can come to this decision by picturing the initial point in your mind. Point X has a positive x-value and a negative y-value. This puts it in quadrant 2 on the coordinate plane. Now, if you flip that point over the y-axis, that makes its new location in quadrant three. In quadrant three, both the x and y coordinates are negative. So, the value wouldn’t change but both would become negatives.

I hope this helps. :)

PLEASEE HEELLLP!!! I'LL GIVE BRAINLIEST!

Answer:

x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96

Step-by-step explanation:

The two angles above the horizontal line form a linear pair, so they are supplementary. Their measures add to 180 deg. That let's you find the value of x.

28x - 7 + 24x + 18 = 180

52x + 11 = 180

52x = 169

x = 169/52

x = 3.25

Now use the lower left angle and the upper right angle. They are vertical angles, so they are congruent. That allows you to solve for y.

12y + 30 = 24x + 18

We know that x = 3.25.

12y + 30 = 24(3.25) + 18

12y + 30 = 78 + 18

12y = 66

y = 66/12

y = 5.5

I don't know what the problem is asking for since you don't show.

x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96
