Answer:

Y = (5/2)x + 3

Step-by-step explanation:

First, we need to make a couple of things clear:

A linear equation has no powers, meaning it makes a straight line.

Slope-intercept form is y = mx + b, where m is the slope, x is, well, x, and b is the intercept.

y and x will both remain as variables in our final solution.

That all said, now we just need to plug in what we were given.

Y = (5/2)x + 3, since our slope is 5/2 and our intercept is 3.

Hope this helps! Now anything you plug in as x will tell you the y-value on this specific line.

The area of a circle is 113.04 in.^2. What is the radius of the circle?

Lelechka [254]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\qquad 
\begin{cases}
r=radius\\
------\\
A=113.04
\end{cases}\implies 113.04=\pi r^2
\\\\\\
\cfrac{113.04}{\pi }=r^2\implies \sqrt{\cfrac{113.04}{\pi }}=r$

Secant jkl and jmn are drawn to circle o from an external point ,j. if jk=8,lk=4 and jm=6 what is the length of jn answer

Archy [21]

See the picture attached to better understand the problem

we know that
If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
so
jl*jk=jn*jm------> jn=jl*jk/jm

we have
jk=8,lk=4 and jm=6
jl=8+4----> 12

jn=jl*jk/jm-----> jn=12*8/6----> jn=16

the answer is
jn=16

Caroline wants to give 8 friends equal size packets of flower seeds to her friends. She has 1/2 pound of flower seeds. How much

Katena32 [7]

You just have to divide the 1/2 a pound by 8, or equivalently multiply by (1/8):

(1/2)*(1/8) = 1/16 of a pound

I golf club charges $10 to join and

Jobisdone [24]

Answer: He could have played more than 3 games.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality.

I golf club charges $10 to join and $5 per game: So, the cost of playing golf is equal to $10 (joining price) plus the product of the number of games played (x) and the price per game (5).

That expression must be higher than 25, since john paid more than $25.

Mathematically speaking

10+ 5 x > 25

Solving for x

5x >25-10

5x >15

x >15/5

x> 3

He could have played more than 3 games, since his cost was higher ( not equal or higher) than 25.
