Add arrows to the two ends of the parabola.
Step-by-step explanation:
To sketch this quadratic function, we to connect three dots: the two roots and a vertex.
The given roots are -1 and 1.
Draw <u>two dots at the x-intercepts</u>, which are (-1, 0) and (1, 0).
Vertex dot: V (x, y)
The vertex x-coordinate always in the middle of the two roots. The middle of -1 and 1 is 0. That's the same as the y-axis.
V (0, y)
Since the function increases when x < 0, the parabola will <u>open up</u>.
We read from left to right. The greater numbers are towards the top of the page.
<u>You can put the vertex anywhere on the y-axis that is below the x-axis.</u>
Answer:
Area of the square is 9.32 cm^2
Step-by-step explanation:
<u>To find the area of a square, square the side.</u>

Answer: Area of the square is 9.32 cm^2
Given Mr. Engle’s total income, I = $52,000 and total expenses, E = $53,800, solving for average difference between income and expenses per month:
(I-E)/12 = ($52,000 - $53,800)/12
(I-E)/12 = - $1,800/12
(I-E)/12 = -$150
This means that Mr. Engle’s expenses exceed his income by an average of $150 each month in the said year.
Answer:
162°
Step-by-step explanation:
They are on a straight line so add to 180
8x + 10 + 2x - 20 = 180
10x - 10 = 180
10x = 190
x = 19
We want AXB so 8x + 10 where x = 19
8(19) + 10 = 162 so it is 162°
Answer:
4
Step-by-step explanation:
Distribute the 2 to the X and 7
4+2x+14=26
2x+18 =26
minus the 18 from 26
2x = 8
divide 2x and 8 by 2
X= 4
