If the graph of the second equation in the system passes through the points (-12, 20)
and (-4, 12), which statements are true? Select all that apply.
- (40,-10) is a solution of the first equation
- (4,4) is a solution of the second equation.
The second equation crosses the y-axis at (0,8)
The x-intercept of the first equation is greater than the x-intercept of the second
equation
The rate of change of the first equation is greater than the rate of change of the
second equation.
The only solution to the system is (-4, 12).
-- who custem is (4.8).

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
