Answer:
First Graph Description
Step-by-step explanation:
A linear function shows as a straight line.
The first graph description describes a straight line.
The second, third, and fourth graph description says that either the line is curved, or that it is a parabola. A parabola is not linear.
A coordinate plane is shown with a line that starts to the left of the y-axis, passing through -1 comma 10, then curving right to pass through the y-axis 7, then curving down to pass through the x-axis at 2
A coordinate plane is shown with a parabola opening downward in an upside-down U shape. The base of the parabola sits at the origin and continues downward on both sides of the y-axis
A coordinate plane is shown. A wavy line begins along the x-axis and moves in intervals downward and back up, dipping down to y equals negative 1 and up to y equals 1.
Hope this helps.
18 = 6x + 18 -6x
18 = x + 18
0=x
Answer:
x = 20
Step-by-step explanation:
x + 2x + (x + 10) = 90° (right angle)
x + 2x + x + 10 = 90
Add like terms
4x + 10 = 90
4x = 90 - 10 (substraction property of equality)
4x = 80
x = 80/4 (division property of equality)
x = 20
The volume of a rectangular prism can be found by the formula lwh. I plug in the numbers I know and set up an equation.
20*x*30=3600
600*x=3600
x=6
The width is 6 cm
