13x-8y=12
Use the slope intercept form to solve the problem.
y = mx+b when the slope is m and the y-intercept is b.
Slope: 13/8
Y-intercept: -3/2
Your answer to 2/3x-4= -2 would be
x=3, or letter D
Answer:
the graph curve will goes above f(x)=x^2.f(x)=3*x^2 curve will also give higher value same value of x .
Step-by-step explanation:
Answer:
x=9
Step-by-step explanation:
All measurements of the interior angles equals up to 180 degrees when added together, therefore add them all together and set it equal to 180.
7x+2+4x+7+8x=180
-Combine like terms
19x+9=180
-Subtract 9 on both sides
19x=171
-Divide by 19
x=9
Usually, the function of a parabola is y=ax^2+bx+c. With your three given points, which I don't know, plug in your x's and y's to come up with three quadratic equations. Using those equations, you use algebra to find out what a, b, and c equal. Once you have a numerical answer, insert them in the usual quadratic function to have your answer.
