-3(x-3)^2+3 find x-intercepts. solve step by step.

1 answer:

8 0

I'll assume this is y=-3(x-3)^2+3

to find the x-intercepts, set y=0 and solve for x:
0=-3(x-3)^2+3
-3=-3(x-3)^2
1=(x-3)^2
+/-1=x-3
+/-1 + 3 = x

x=4, x=2

this makes sense because if you look at the original equation, you see that plugging in these numbers for x, you get 0.

The coordinates of the vertices of ANGLE RST are R(-3,5), and S(4,5), and T(4,-2). Find the side lengths to the nearest hundredt

e-lub [12.9K]

Side lengths: RS=7 and ST=7, and angle=90 degrees

Why?

Since second coordinates of R and S are the same so we can just count the length by adding first coordinate of R and first coordinate of S= |-3|+4=7

Since first coordinates of R is the same as first coordinate of T so we can just count the length by adding second coordinates of S and T=5+|-2|=7

Angle: RST is =90 degrees because triangle RST is right angled triangle. Why? Because RS is parallel to X axis(the same second coordinates of R and S) and ST is parallel to Y axis(the same coordinates of S and T) .

Solve for x. <br><br> 8x/7+9=30

kodGreya [7K]

X=18 (3/8)
(8x/7) +9 = 30
subtract 9 from both sides
8x/7=21
multiply 7 from both sides
8x=147
divide 8 from both sides and you get
x=18 (3/8)
