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.)
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
Answer:
(30, ∞)
Step-by-step explanation:
b – 27 > 3
Add 27 to both sides
b > 30
In interval notation
(30, ∞)
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,

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

Put this value of x in second equation:

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

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