Can you make the answer clearer. I would be glad to help you. I just don't understand where it says "the sum of three numbers is 16 the sum of twice the first number"
8x > = -64
x > = -64/8
x > = -8
10x < 60
x < 60/10
x < 6
-8 < = x < 6
Answer:
Equation = y = -4x+7
See the graph below
Step-by-step explanation:
The equation of the line in slope intercept form is expressed as;
y = mx+c
Given
slope m = -4
y-intercept c = 7
Substitute
y = -4x + 7
Get the x intercept.
at y = 0
0 = -4x + 7
4x = 7
x = 7/4
x = 1.75
The x coordinate (1.75, 0)
Get the y intercept
at x = 0;
y = -4(0)+7
y = 0+7
y = 7
The y coordinate is (0, 7)
Answer: 3
Step-by-step explanation:
Let's create a model first.
The initial fee is $19 (this is our y intercept or b)
And the pay per is $4 (this is our variable or m)
y=mx+b
y= 4x+19
To find out what the maximum number of events someone can attend for $31, we plug in different number for the x value until it's less than or equal to $31
In this case, plugging in 3 for x gives us exactly $31
y=4(3)+19= 31
