Answer:
(0,0)
Step-by-step explanation:
x value of vertex = -b/2a
ax^2+bx+c
-2x^2+0x+0 sinc you have no value of b & c in your quadratic function
-b = 0
2a = (2)(-2)
-b/2a = (0/-4) = 0
x value of the vertex = 0
plug 0 in for all values of x in the function to find y coordinate value
-2(0)^2 = 0
(x,y) = (0,0)
Answer:
It should be 21.1
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation.
Answer:
1- click
2--trick
3- track
4-trace
Step-by-step explanation:
equation (y=x+2) x y
y=-3+2 -3 -1
y=-1+2 -1 1
y=0+2 0 2
y=2+2 2 4
you can plot the points ( click)
<h2>equation (y=-x) x y</h2>
y=-(-2) -2 2
y=0 0 0
y=-1 1 -1
y=-3 3 -3
plot the points
<h2>equation (y=1) x y</h2>
y=1 no matter what the value of x -3 1
(-3,-1,0,2) -1 1
0 1
2 1
<h2>y=1/2 x +1 x y</h2><h2> y=-4/2 +1 -4 1</h2>
y=-2/2 +1 -2 0
y=1/2(0)+1 0 1
y=3/2 +1 3 2.5
there are no image for 5 and 6
11.) You pay 620 to rent a hotel room for 4 weeks. Total cost include an initial deposit plus a weekly fee of 125.
a)y=(rate per week)x+deposit
620=125x+deposit
620=125(4)+deposit
620=500+deposit
620-500=deposit
120=deposit
y=125x+120
b) y-intercept is the deposit, at 120
