Answer:
A. y = -10x
Step-by-step explanation:
An equation that has a line that passes through the origin (0, 0) is represented in slope intercept form as y = mx
Where, m is the slope.
Therefore,
The equation that represents a graph with a negative slope and passes through the origin would be:
y = -10x
-10 is the slope (m).
Answer:
$51
Step-by-step explanation:
51 x 1.2 = $61.2
61.2 x 1.2 = $73.44
73.44 x 1.2 = $88.13
88.13 x 1.2 = $105.75
105.75 x 1.2 = $126.90
Since the lines are parallel, they have the same slope.
Slope of first line: y=1/4x-2
Slope of parallel line: y=1/4x+b
Plug in the point that the line passes through to find b. Plug 4 in for x and -2 in for y.
-2=1/4(4)+b
Multiply.
-2=1+b
Subtract 1 from both sides.
-3=b
Equation of the parallel line: y=1/4x-3
Hope this helps! :)
An expression not equivalent to 1/343 is 1/342.
Answer:The inequality is
x greater than or equal to(>/=) 14
Step-by-step explanation:
Let x represent the possible cost of the full pizza. Tara eats 3 of the 10 slices and pays $4.20 for her share. This means that the amount of pizza that Tara ate is 3/10×x = 3x/10
Assuming that Tara has paid at least her fair share, therefore
3x/10 = 4.20
3x = 4.20 ×10 = 42
x = 42/3 = 14
This means that the total cost of the pizza is at least $14. The inequality
how much the pizza could have cost becomes
x greater than or equal to(>/=) 14
