Answer:

x intercept : (5,0)

y intercept : (0,-2)

2/5 is the slope

Step-by-step explanation:

when finding the intercept of a line with ax + by = c you make the other variable 0. This is due to the fact that if it is x intercept it it (x,0) and if it is y intercept it is (0,y) so if you plug in the other variable is 0.

x intercept : (5,0)

y intercept : (0,-2)

When finding a slop and knowing 2 points you can use the formula.

y(2nd one) - y(1st one)

---------------------------------

x(2nd one) - x(1st one)

-2 - 0 -2 2

--------- = -------- = -------

0 - 5 -5 5

2/5 is the slope

Hope this helps

A ball is thrown upward with an initial velocity of 60 mph. it is thrown from a height of 5 feet. what is the maximum height it

natima [27]

Answer:

h = 61.25 m

Step-by-step explanation:

It is given that,

The initial velocity of the ball, v = 60 m/s

It is thrown from a height of 5 feet, $h_o=5\ ft$

We need to find the maximum height it reaches. The height reached by the projectile as a function of time t is given by :

$h=-16t^2+vt+h_0$

Putting all the values,

$h=-16t^2+60t+5$ .....(1)

For maximum height, put

$\dfrac{dh}{dt}=0\\\\\dfrac{-16t^2+60t+5}{dt}=0\\\\-32t+60=0\\\\t=\dfrac{-60}{-32}\\\\t=1.875\ s$

Put t = 1.875 in equation (1)

$h=-16(1.875)^2+60(1.875)+5\\\\h=61.25\ m$

So, the maximum height reached by the ball is 61.25 m.

What is the solution of 9x-8=34x-12

Cerrena [4.2K]

Answer: x = 2/13

Step-by-step explanation:

9x-8=34x-12

Add 12 on both sides and you get

9x+4=34x

Subtract 9x from both sides and you get

4=26x

Divide 26 from both sides to get

X= 4/26

Carys calculates the total amount EEE, in dollars, that she earns for working hhh hours using the equation E=10hE=10hE, equals,

timurjin [86]

Answer:

$10 per hour
0.1 hours

Step-by-step explanation:

To find Carys' earnings in one hour, fill in h=1 in the formula:

E = 10·1 = 10

Carys earns 10 dollars per hour.

To find the number of hours required to earn 1 dollar, fill in E=1 in the formula:

1 = 10h

0.1 = h . . . . . divide by 10

It takes 0.1 hours for Carys to earn 1 dollar.
