You know how many she started and finished with.
To find the amount she ate, subtract the end amount from the start amount.
Subtract 6 from 21
She ate 15 gummy bears.
x=11
x is equal to 11 because you subtract 4x from both sides and then add 8 to both sides where you are left with 2x=22. After dividing by 2, you get x=11
Answer:
In order to sketch a parabola, one will typically use the y-intercept, the x-intercepts, and the vertex.
Step-by-step explanation:
In order to sketch a parabola, one will typically use the given equation in standard form,
, and:
- The y-intercept – the point where the parabola crosses the vertical axis – by substituting 0 for all <em>x</em> values in the given equation and solving for <em>y</em>.
- The x-intercepts – the points where the parabola crosses the horizontal axis – by setting the given equation equal to 0 (i.e., <em>y</em> = 0) and finding the factors (or roots).
- The vertex – the point of symmetry where the parabola changes direction and curves up or down – by using
to find the x-coordinate then plugging that value into the given equation to find the y-coordinate.
Since the two consecutive integers are even, one of them will be represented by x and one will be x + 2.
x + (x + 2) = 226 Combine like terms
2x + 2 = 226 Subtract 2 from both sides
2x = 224 Divide
x = 112
The two integers are 112 and 114. You can double check by them
112 + 114 = 226
