Answer:
(1.13, 7.74) and (-4.13, 18.26)
Step-by-step explanation:
This can be solved in two ways: mathematically and graphically.
<u>Graphing</u>
Plot both lines and find where they intersect. See the attachment.
The intersection points are (1.13, 7.74) and (-4.13, 18.26)
<u>Mathematical</u>
y + 2x = 10
y = 10 - 2x
y = 3x² + 7x - 4
10 - 2x = 3x² + 7x - 4
3x² + 9x - 14 = 0
Solve this using the quadratic equation:
x = 1.13 and -4.13
Use these two values of x to find y:
y = 10 - 2x
y = 10 - 2(1.13)
y = 7.74
y = 10 -2x
y = 10 -2(-4.13)
y = 18.26
The two points are:
(1.13, 7.74) and (-4.13, 18.26)
Answer:
y=
x-3
Step-by-step explanation:
slope intercept form is y=mx+b
b is y intercept
so we plug the coordinate into the equation
-3=(0)+b
-3=b
so y intercept is -3
so we then write our equation which is,
y=x-3

Answer:
(-∞, -2]
Step-by-step explanation:
Domain of a function is defined by the x-values (Input values) and y-values define It's range.
From the graph of a parabola,
Graph shows the increase in the value from x = -∞ to x = -2 then the values are decreased from x = -2 to ∞.
Therefore, domain in which the function is increasing : (-∞ , -2]
