Equation of a line tha passes through thte point (x1,y1) and has a lsope of m is
y-y1=m(x-x1)

given
m=1/2
point is (2,-1)
x1=2
y1=-1

y-(-1)=1/2(x-2)
y+1=1/2(x-2)
if yo want slope intercept
y+1=1/2x-1
y=(1/2)x-2

I believe the equation would be y=mx+b, m being slope, b being y-intercept, so it would mean that you need to plug in the numbers. I believe the final equation would be y=1/2x+(-1)

The Cowboys High School Band Boosters are selling candy bars and chips at the basketball tournament to raise money for their ban

masya89 [10]

Answer:

They have 425 candy bars ready to sell.

Step-by-step explanation:

Let,

x be the number of candy bars ready to sell

y be the number of chips ready to sell

According to given statement;

x+y=575 Eqn 1

x+0.5y= 500 Eqn 2

Subtracting Eqn 2 from Eqn 1

(x+y)-(x+0.5y)=575-500

x+y-x-0.5y=75

0.5y = 75

Dividing both sides by 0.5

$\frac{0.5y}{0.5}=\frac{75}{0.5}\\y=150$

Putting y=150 in Eqn 1

x+150 = 575

x = 575-150

x = 425

Hence,

They have 425 candy bars ready to sell.

What number must be placed in the box in the equation below to produce an equation that has more than one solution: 5u+3(4u-6)=-

Sergeeva-Olga [200]

Answer: the number must be placed in the box is 9

suppose: the number must be placed in the box is x

have:

5u + 3(4u - 6) = -3u -27 + 20u + x

⇔ 5u + 12u - 18 = -3u - 27 + 20u +x

⇔ 17u + 3u - 20u = -27 + 18 + x

⇔ 0 = x - 9

⇔ x = 9

How to <br> Write <br> 3/9<br> in simplest form.

White raven [17]

To write it in simplest form, you must find a common factor.

In $\frac{3}{9}$ , 3 is a factor of both 3 and 9

3÷3=1 and 9÷3=3

So $\frac{3}{9} = \frac{1}{3}$

$\frac{1}{3}$ is your answer in simplest form.
