Answer:
y=36/9 or y=4
Step-by-step explanation:
3x=15: x=5
y=7(5)+1/3(5)-6
y=36/15-6
y=4
Answer:
area = 3 2/3 units^2
Step-by-step explanation:
1 1/3 x 2 3/4 = 4/3 x 11/4 = 44/12 = 3 2/3 units^2
The answer is 3x^2 - 2.
x^2+3y-3+2x^2-3y+1
Add the like terms together, you get 3x^2 - 2
The shape in the middle is a quadrilateral, so the bottom right hand corner should add up to the rest of the angles to give 360 degrees.
40 + 80 + 110 = 230°
360 - 230 = 130°
The line on which x is on is a straight line, and a straight line is 180 degrees.
Therefore x has to be 180 - 130 to make sure it adds up to give 180 degrees.
180 - 130 = 50
∴ x = 50°
Statement 1 is false because the domain of f is all real numbers since the function is quadratic.
Statement 2 is true<span>.
Statement 3 is true because when we graph f, it is a parabola opening upwards with vertex (3, -1). Since it is opening upward, then the value of x from -</span>∞ to 3 is decreasing while increasing from 3 to ∞.
<span>
Statement 4 is false because we just stated above that f is decreasing from -</span>∞ to 3. Hence, f is also decreasing from -1 to 3. Hence, f is not increasing from -1 to <span>∞.
</span><span>Statement 5 is false because the axis of symmetry is x = 3.
Statement 6 is true.</span>
