Graph the function

Assoli18 [71]

Answer:

see below for a graph

Step-by-step explanation:

The equation is in slope-intercept form, so right away you know one point is the y-intercept: (0, -4).

Another point can be found using the slope, which is 3/2, to go 2 units to the right and 3 units up. (Slope = rise/run, so rise = 3 and run = 2 match the slope.)

Find the equation of the line that passes through the two points (5,-3) and (-5,2). Write your answer in standard form. Help me

lidiya [134]

Answer:

x + 2y = -1

Step-by-step explanation:

First, we'll find the slope.

Slope = (2 - (-3)) / (-5 - 5) = 5 / -10 = -1/2

Since we know the slope and a point that belongs to the line, we can write this in point-slope form which will be:

y - 2 = -1/2(x - (-5)) *I used (-5, 2) but it doesn't matter which point you use

y = -1/2(x + 5) + 2

y = -1/2x - 1/2

Standard form:

1/2x + y = -1/2

x + 2y = -1

at Redbox mike rents 2 DVD's and 3 games for total of $15.50. At the same time John rents 3 DVD's and 1 game for a total of $12.

Answer: Cost of DVD is $2.95 and cost of games is $3.2.

Step-by-step explanation:

Let the cost of DVD be x

Let the cost of games be y

So, According to question,

$2x+3y=\$15.50\\\\and\\\\3x+1y=\$12.05$

Now, we will apply " Substitution Method " i.e.,

$2x=15.50-3y\\\\x=\frac{15.5-3y}{2}$

Put this value of x in second equation:

$3x+y=12.05\\\\3\times \frac{15.5-3y}{2}+y=12.05\\\\46.5-9y+2y=12.05\times 2\\\\46.5-7y=24.1\\\\46.5-24.1=7y\\\\22.4=7y\\\\\frac{22.4}{7}=y\\\\3.2=y$

Now, substitute the value of y in equation of x:

$x=\frac{15.5-3y}{2}\\\\x=\frac{15.5-3\times3.2}{2}\\\\x=\frac{15.5-9.6}{2}\\\\x=\frac{5.9}{2}\\\\x=2.95$

Hence, Cost of DVD is $2.95 and cost of games is $3.2.
