Mathematics

6 0

Answer:

x is 1.5 and 2.8

Step-by-step explanation:

1. 2x + 3

2x = 3

x = 3/2

x = 1.5

2.  4 × 2 - 5x +6

8 - 5x + 6

-5x + 6 + 8

-5x + 14

-5x = -14

Divide both sides by -5, we will have

x = -14/-5

x = 2.8

Y = −(x + 4)2 − 7 vertex
ICE Princess25 [194]

Answer:

The vertex (h,k) is (-4,-7).

Step-by-step explanation:

I assume you are looking for the vertex y=-4(x+4)^2-7.

The vertex form of a quadratic is y=a(x-h)^2+k where the vertex is (h,k) and a tells us if the parabola is open down (if a<0) or up (if a>0). a also tells us if it is stretched or compressed.

Anyways if you compare y=-4(x+4)^2-7 to y=a(x-h)^2+k , you should see that a=-4,h=-4,k=-7.

So the vertex (h,k) is (-4,-7).

Urgent!!!!?
ExtremeBDS [4]

Answer:

C) 6 feet

Step-by-step explanation:

The diagram is shown in the attachment.

Using the Pythagoras Theorem,

x^2=4^2+4^2

x^2=16+16

x^2=32

We take positive square root to obtain

x=\sqrt{32}

x=4\sqrt{2}

x=5.66ft

Rounding to the nearest feet we have x=6ft
