Answer:
The cost is $322.88.
Step-by-step explanation:
18% off the list price of $375
Before the sales tax, you pay 100% - 18% = 82% = 0.82 of 375, so:
0.82*375 = 307.5
5% sales tax:
100% + 5% = 105% = 1.05 of 307.5. So
307.5*1.05 = 322.88
The cost is $322.88.
The answer is inconsistent
Answer:
So a point is (-3,-5) and the vertex is (-4,-3)
Step-by-step explanation:
This is in vertex form. Vertex form is y=a(x-h)^2+k where (h,k) is the vertex.
The vertex here is (-4,-3)... now just use a value of x to plug in (any value besides -4)
I will choice -3. This gives -2(-3+4)^2-3
f(-3)=-2(1)^2-3
f(-3)=-2-3
f(-3)=-5
So a point is (-3,-5) and the vertex is (-4,-3)
