Graph the linear equation find three points that solves the equation 2y=5x+11
Julli [10]

Answer:

<h3>Attachment</h3>

Step-by-step explanation:

Convert to the slope-intercept form (<em>y = mx + b</em>):

2y=5x+11             <em>divide both sides by 2</em>

\dfrac{2y}{2}=\dfrac{5x}{2}+\dfrac{11}{2}\\\\y=\dfrac{5}{2}x+\dfrac{11}{2}

We choose any three x values ​​and calculate the y value:

for x = -1

y=\dfrac{5}{2}(-1)+\dfrac{11}{2}=-\dfrac{5}{2}+\dfrac{11}{2}=\dfrac{6}{2}=3\to A(-1,\ 3)

for x = 1

y=\dfrac{5}{2}(1)+\dfrac{11}{2}=\dfrac{5}{2}+\dfrac{11}{2}=\dfrac{16}{2}=8\to B(1,\ 8)

for x = -3

y=\dfrac{5}{2}(-3)+\dfrac{11}{2}=-\dfrac{15}{2}+\dfrac{11}{2}=-\dfrac{4}{2}=-2\to C(-3,\ -2)

Mark the points on the coordinate plane and draw a line through the given points.

Saving money is essential to living life. Everything costs money. Even this wifi? Not free. The device you asked this on? Not free. Saving money is important but why won't people do it? They think its hard, but it's actually easy. Step one, save one cent today, two cents tomorrow, three cents the next day...etc. That leaves you with 365 in the bank if I did the calculations right. Another way you can save is by setting a budget. Pretty easy, but you have to control what you buy and understand that buying this or that could prevent you from buying something else. The last one? Get a job. Preferably a one that gets you a higher pay without actually needing a degree, like a warehouse worker or a waiter.
These methods help you in the best way possible to save money. Good luck!

The area of a rectangle room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equatio
olga_2 [115]
By definition, the area of a rectangle is given by:
 A = (width) * (long)
 Substituting values we have:
 750 = (y-5) * (y)
 Rewriting we have:
 750 = y ^ 2 - 5y
 y ^ 2 - 5y - 750 = 0
 Answer:
 
An equation that can be used to solve for And the length of the room is:
 
y ^ 2 - 5y - 750 = 0

Rearrange y =1/2x+1to make x the subject.
ella [17]

❤❤❤❤❤❤❤❤❤❤❤❤❤❤

y =  \frac{1}{2} x + 1 \\

Multiply sides by 2

2 \times y = 2 \times ( \frac{1}{2} x + 1) \\

2y =( 2 \times  \frac{1}{2} x) + (2 \times 1) \\

2y = x + 2

x + 2 = 2y

Subtract sides 2

x + 2 - 2 = 2y - 2

x = 2y - 2

Done...

❤❤❤❤❤❤❤❤❤❤❤❤❤
