Answer:
A is (-3,0) and (1,0).
B is (-1, -2).
Step-by-step explanation:
To find the x-intercepts, look along the x-axis and where the line goes through it. Those two locations are your answer.
To find the vertex, you can find the axis of symmetry by taking its equation and putting it into the form of x = -b/2a or finding the lowest or highest point in the line. In this example, it is (-1, -2) as the lowest point, and there is not a highest point to find, since it is in a u-shape.
The area equation for the given rhombus is:
A = (x^2 + 2x - 8) m^2
So the correct option is the second one.
<h3>
How to get the area of the rhombus?</h3>
For a rhombus of diagonals d₁ and d₂, the area is given by:
A = (d₁*d₂)/2
In this case, we have:
d₁ = (2x + 8)m
d₂ = (x - 2)m
Then the area equation is:
A = (1/2)*(2x + 8)*(x - 2) m^2
A = (x + 4)*(x - 2) m^2
A = (x^2 - 2x + 4x - 8) m^2
A = (x^2 + 2x - 8) m^2
So the correct option is the second one.

Answer:
54
Step-by-step explanation:
The external angle is half the difference of the subtended arcs.
x° = (136° -28°)/2 = 108°/2
x = 54
Answer:
100
Step-by-step explanation:
Number of seat in sector A = number of rows * number of seats
= 9 * 8
= 72
Number of seat in sectorB = number of rows * number of seats
= 4 * 7
=28
Total seats = 72 + 28 = 100
Answer:
Step-by-step explanation:
y-4=-2(x-3)
y-4=-2x+6
making y the subject
y=-2x+6+4
y=-2x+10
