2t-7-5t=11 what is the answer
Verizon [17]
<span>2t-7-5t=11

Start by combing like terms:

2-5t=-3t  

Now we have: 

-3t-7=11  

Add 7 to both sides

-3t=18

To isolate t we divide both sides by -3 

Final answer: 
t=-6 </span>

I need help please please
Aliun [14]

Answer:

y= -4/3x +8

Step-by-step explanation:

well first you got to simply for equation

4x +3y = 24

so you subtract 4x to both sides and that gives you : 3y= -4y +24

then you divide everything by 3

and that leaves you with : y= -4/3x +8

and the graph just put a dot on 8 on the y axis then go down -4 and left 3

The height of a cable that runs between two supports on a suspension bridge can be modeled by a quadratic function () where is t
Murrr4er [49]

What is the vertex

Its vertex is at (36, -10)

Let us assume that the left edge of the cable is at the origin.

Since the cable is at its lowest height 10 feet halfway between the two supports, the y-coordinate of its lowest point is -10 ft and the x coordinate is 72 ft/2 = 36 ft.

So, its vertex is at (36, -10)

Axis of symmetry

The y-axis.

Since the cable is symmetric about its lowest point, the axis of symmetry is the y-axis.

Domain

The domain is (0, 72).

Since the minimum value of its x-coordinate is at the origin which is x = 0 and the maximum value is at the other support which is at x = 72 ft,

the domain is (0, 72).

Range

The range is (0, -10)

Since the minimum value of the y-coordinate is -10ft and the maximum value is at the origin y = 0,

the range is (0, -10)

x and y-intercepts

The x-intercept is (0, 72) and the y-intercept is (0, 0)

Since the cable is attached at the origin and at 72 feet away  from the origin at the other support, the x-intercept is 0 and 72 ft and the y-intercepts are 0 and 0.

So, the x-intercept is (0, 72) and the y-intercept is (0, 0)
