Find the solution(s) to the system of equations. Select all that apply.
y=x²-4
y=-x-2
Answers
The solution will be the intersection points thus options A (1,-3) and B (-2,0) will be correct.
What is a graph?The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.
For example plot of y = x³ ,y = sinx.
The solution will be the intersection points of both functions.
At the intersection point,
x² - 4 = -x - 2
x² + x - 2 = 0
x² + 2x - x - 2 = 0
x(x + 2) - (x + 2) = 0
(x - 1)(x + 2) = 0
x = 1,-2
At x = 1
y = -1 - 2 = -3 so first intersection is (1,-3)
At x = -2
y = -(-2) - 2 = 0 so second intersection is (-2,0)
Hence "The solution of the given system of equations is (1,-3) and (-2,0)".

Answers
Answer:
44.7
Step-by-step explanation:
Find the mean of the data set shown below. Round to the nearest tenth, if necessary.
This Week's High Temperatures (°F)
29, 38, 45, 31, 50, 58, 62
The formula for the Mean of a given set of data is
= Sum of terms/ Number of terms
Number of terms = 7
Hence,
Mean = 29+ 38+ 45+ 31+ 50+ 58+ 62/7
Mean = 44.714285714286
Approximately to the nearest tenth= 44.7

JKLM is a rectangle. if JL = 4x - 12 and MK = x, what is the value of x? what is the length of each diagonal?
Answers
Answer:
x = 4
The diagonals are both 4
Step-by-step explanation:
The fact that the two sides have no letter in common indicates that they are opposite each other or a diagonal. In this case the length is a diagonal. Diagonals in a rectangle are equal.
4x - 12 = x Add 12 to both sides
4x - 12 + 12 = x + 12 Subtract x from each side
4x - x = 12
3x = 12 Divide by 3
3x/3 = 12/3
x = 4
One of the diagonals = 4 because it is x.

58+73+12x+1=180
132+12x=180 (I got 132 by adding 58,73,1)
Subtract 132 from both sides
You should get 12x=48
Divide both sides by 12
X=4
(12x + 1) + 58° + 73° = 180°
12x + 132° = 180°
12x = 180° - 132°
x = 48°/12
x = 4°
