Mathematics
1 answer:
Brums [2.3K]3 years ago
5 0

Answer: C

Step-by-step explanation:

Looking at the triangle, we see that the angles are the same. This tells us the triangle is an isosceles triangle. That means the two adjacent sides are equal to each other.

4x+23=10x-1       [subtract both sides by 4x]

23=6x-1               [add both sides by 1]

24=6x                  [divide both sides by 6]

x=4

Now, we know that x=4.

Help and please explain so I can do it on my own. There are a couple more on this sheet.​
Andreas93 [3]

Answer:

(2, -10)

Step-by-step explanation:

so first i find the axis of symmetry using the equation x= -b/2a

in this problem

a=3

b= -12

c= 2

- (-12)/ 2(3) = 2

2 will be the x point for your vertex

you then plug in your x point into the original equation and solve for y

y = 3(2)^2 - 12(2) +2

y = -10

Vertex is then (2, -10)

borishaifa [10]
X cannot equal +2, and can't be -1. If you factor it, then you notice you get 2(x+2)(x-2). If you use either one for the x, one will be zero and the won't, and vise-versa.
