Answer:
X-intercept: (-0.2,0)
Step-by-step explanation:
y=15x+3
I don't know how to show a graph but what you do is start by plotting (0,3) and go up 15 and over 1 to form a line (because the slope is 15).
To find the x-intercept, replace y with 0 and solve for x.
0=15x+3
-3=15x
-3/15
-1/5 (or -0.2)
(-0.2,0)
Answer:
D 1.29x+1.35y≤12
Step-by-step explanation:
Nick is making a fruit salad. He buys apples for $1.29 per pound and oranges for $1.35 per pound. He spends no more than $12.
Let x represent the number of pounds of apples that Nick buys. Let y represent the number of pounds of oranges that Nick buys.
1.29x+1.35y≥121.29x+1.35y≥12
1.29x+1.35y>121.29x+1.35y>12
1.29x+1.35y<121.29x+1.35y<12
1.29x+1.35y≤12
To solve this problem, we need to pick numbers from the table then this number will be substituted into the equation. But first, we equate the numbers such as below:
4x - 2y = 8
Transpose -2y to the right side such as:
4x = 8 + 2y
4x - 8 = 2y
(4x -8)/2 = y
2x - 4 =y
From the table, let us choose x = 0
y = 2x -4
y = 2(0) -4
y = -4
From the table, let choose another value of x such as x=1
y = 2(1) -4
y = 2 - 4
y = -2
This will prove that the values in the table are correct.
