Will give brainliest to whoever answers first and correct

aliina [53]

Answer:

A is f(t)=-(t-4)^2+50

B is 50. the top of the graph is at 50

C is at 4. that is the x value when y=50

If you need the graph put the answer from question A into Desmos

The answer is C, but I don't understand why- can anyone tell me?

finlep [7]

Answer:

It's C because we are adding a number on the x but here we skip 5 so it's 6, and on y we add 4 up but since we skipped 5 we add 8 and we get 24. 6, 24. You may say "but SpiritBear, 17 plus eight is 25" and that is true, but if you notice the lowest dot actually starts on 5, not 4 making C right.

Hope this helped and wasn't too confusing

PLZZ HELP I’m bad at math.

ipn [44]

Answer:

y< $\frac{-1}{3}$ x+1 is inequality shown on graph.

Step-by-step explanation:

The graph shows representation of inequality,

Here, Line passes through points say, A(3,0) and B(0,1)

The slope of line is given by m= $\frac{Y2-Y1}{X2-X1}$

m= $\frac{Y2-Y1}{X2-X1}$

m= $\frac{1-0}{0-3}$

m= $\frac{-1}{3}$

and Y-intercept is c=1

The equation of line is given by y=mx+c

y= $\frac{-1}{3}$ x+1 is equation of line in graph.

To decide which side you are going to shaded area on the graph

Take test of origin.

If (0,0) is statisfy the equation then, shaded the graph towards the origin.

Let suppose,

Take, y< $\frac{-1}{3}$ x+1

0< $\frac{-1}{3}$ (0)+1

0<1

TRUE,

Therefore, y< $\frac{-1}{3}$ x+1 is inequality shown on graph.
