4) The solution of 2 lines is where they intersect. In this case it is (4,4) for both lines A and B.

5) Two lines with infinite solutions mean that they are the exact same line, so you can change the original equation to y=mx+b form.

2x + 2y = 8 divide each side by 2 to get x + y = 4

Two cars leave towns 300 kilometers apart at the same time and travel toward each other. One car's rate is 16 kilometers per hou

julia-pushkina [17]

The cars travel with constant speed, and the equations of movement of each one are,

$x_1=v_1t$

$x_2=x_0-v_2t$

Where v_1=16 Km/h, v_2 is unknown, x_0 is 300 kilomters. As they meet in 2 hours, then t=2 and x_1=x_2, so,

$x=v_1t$

$x=x_0-v_2t$

Solving for v_2,

$v_2=x_0/t-v_1=134\ \ Km/h$

I NEED HELP ASAP PLEASEEEE!!!!!

earnstyle [38]

Answer:

Step-by-step explanation:

Use Pythagorean theorem.

Hypotenuse² = base² + altitude²

5) x² = 12² + 6²

= 144 + 36

x² = 180

x = √180

x = 13.42 ft

6) 25² = x² + 19²

625 = x² + 361

625 - 361 = x²

x² = 264

x = √264

x = 16.25 m

7) x² = 7² + 576

= 49 + 576

= 625

x = √625

x = 25 in

8) 2.5² = 2²+ x²

6.25 = 4 + x²

6.25 - 4 = x²

x² = 2.25

x = √2.25

x = 1.5 yd

Answer:

irrational

Step-by-step explanation:

√5 is a non terminating and non recurring number therefore it can't be written as quotient of two numbers so it is irrational.

Note:if you need to ask any question please let me know.

27.2163 rounded to the nearest hundredth

algol [13]

Answer:

27.0000

Step-by-step explanation:

27.2163 rounded to the nearest hundredth is 27.0000 or 27 because the hundredth place held a 1 and 5 or above rounds up and 4 or below rounds down. The .2163 turned into zeros because the second number (the hundredths place) was a 1 so it rounded down, and hen it rounds down, all the numbers round to 0.
