Answer:

(7, 1/2)

Step-by-step explanation:

Multiply second equation by 2 and subtract.

3x - 4y = 19

- (4x - 4y = 26)

You get -x = -7

x = 7

Substitute x into any equation.

3(7) - 4y = 19

21 - 4y = 19

-4y = -2

y = 1/2

Answer:

the triangle

Step-by-step explanation:

The perimeter is the sum of the all sides of the shape.

Triangle:

3√147+2√108+2√48+3√75+ 6√12

147=49•3, 108=36•3, 48=16•3, 75=25•3, 12=4•3 that means

√147=7√3, √108=6√3, √48=4√3, √75=5√3, √12=2√3

perimeter=3•7√3+2•6√3+2•4 √3+3•5√3+6•2√3=68√3

Square:

4•1/3•√63=4/3•√9•√7=4√7

Rectangle:

2•1/4√100+2(2√48+4√75)=

5+2(8√3+20√3)=5+56√3

Now, if you use a calculator, you will find that the greatest perimeter is for the triangle shape.

Complete the system that models the heights of the ball and the receiver’s hands over time. h = -16t² 14t h = -16t² t
bogdanovich [222]

Answer: The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8

What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

A quarterback throws a football toward a receiver from a height of 6 ft. The initial vertical velocity of the ball is 14 ft/s. At the same time that the ball is thrown, the receiver raises his hands to a height of 8 ft and jumps up with an initial vertical velocity of 10 ft/s.

The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8
