What is the x & y-intercept of 6x-2y=12
Norma-Jean [14]

Step-by-step explanation:

to find the x intercept make y =0

6x - 2(0) = 12

6x = 12

x= 2

x intercept (2,0)

to find y intercept make x=0

6(0) - 2y = 12

-2y = 12

0= 12 + 2y

-12 = 2y

y= -6

y intercept (0,-6)

Answer:

The first expression to be solved first will be the exponets the 6 with the tiny 2

Step-by-step explanation:

PEMDAS is an acronym for the order of operations: Parenthesis, Exponent, Multiplication/ division, addition/subtraction. You solve the equation by answering it in that order, with the / answers being done simultaneously left to right (there is probably a better way to explain this, and I’m sure other users will clarify).

A ball is thrown upward from a height of 15 ft with an initial velocity of 5 ft/s. Use the equation h=-16t^2+5t+15 to answer the
Fiesta28 [93]

Answer:

1) 1.1 seconds

2) 13.5 feet

<h3>Part A</h3>

\rightarrow \sf  -16t^2 + 5t + 15 = 0

<u>Apply quadratic formula</u>:

\rightarrow \sf t=   \dfrac{-5\pm \sqrt{5^2-4\left(-16\right)\cdot \:15}}{2\left(-16\right)}

<u>Simplify following</u>

\rightarrow \sf t=-\dfrac{-5+\sqrt{985}}{32},\:t=\dfrac{5+\sqrt{985}}{32}

In decimal form:

\rightarrow \sf t=-0.825 ,\:t=1.137

Conclusion:

As time is be only positive: t = 1.1 seconds

<h3>Part B</h3>

\rightarrow \sf  h=-16t^2 + 5t + 15

<u>insert t = 0.5</u>

\rightarrow \sf  h=-16(0.5)^2 + 5(0.5) + 15

<u>simplify</u>

\rightarrow \sf  h=13.5

Answer:

  arithmetic; common difference of 5

Step-by-step explanation:

It usually works well to check differences first. Here, they are ...

  8 -3 = 5

  13 -8 = 5

These are the same value, so the sequence is arithmetic with a common difference of 5.
