Answer:
Mitch=60*4=240
Jo=60*3=180
Step-by-step explanation:
420/7=60

X = 11
angle LKM = angle KLM = angle LMK because it is an equilateral triangle
180/3 = 60
60=3x-27
60-27=3x
33=3x
x=11
Answer:
(5,6)
Step-by-step explanation:
8X +6Y=4
Y=-3X+9
Substitute the second equation into the first. Every place you see y put -3x+9)
8x +6(-3x+9)=4
Distribute
8x-18x +54 = 4
Combine like terms
-10x +54 = 5
Subtract 54 from each side
-10x +54-54=4-54
-10x = -50
Divide by -10
-10x/-10 = -50/-10
x= 5
Now we need to find y
y = -3x+9
y = -3(5) +9
y = -15+9
y= 6
(5,6)
Step-by-step explanation:
the point being that a quadratic equation has 2 x-intercepts (or solutions of x for y = 0).
the advantage of this nice form the equation is written in is, that we see immediately both conditions, when y can be 0 : one of the bracket expressions must be 0.
so, the point (1, 0) covers (x-1).
we get the solution for (x-n), when we consider that such a quadratic function is simply a parabola and is symmetric around its vertex point.
the x value of the vertex (-2) tells us, that it is 3 units on the left side of the (1, 0) x-intercept point.
due to the symmetry of the curve the second x-intercept point must be even further to the left with additional 3 units distance in x direction.
so, -2 - 3 = -5
and A is the correct answer option.
