C.2X√2X
D.√10X^3

Answers

Answer 1
Answer: √(18x^3)-√(9x^3)+3√(x^3)-√(2x^3)\n\n=√(9x^2\cdot2x)-√(9x^2\cdot x)+3√(x^2\cdot x)-√(x^2\cdot2x)\n\n=3x√(2x)-3x√(x)+3x√(x)-x√(2x)=2x√(x)\n\nAnswer:C.
Answer 2
Answer: √(18x^3)-√(9x^3)+3√(x^3)-√(2x^3)=\n 3√(2x^3)-3√(x^3)+3√(x^3)-√(2x^3)=\n 2√(2x^3)=\n 2x√(2x)\Rightarrow C

Consider the graph of the linear function h(x) = –6 + h(x) equals negative 6 plus StartFraction 2 Over 3 EndFraction x. x. Which quadrant will the graph not go through and why? Quadrant I, because the slope is negative and the y-intercept is positive Quadrant II, because the slope is positive and the y-intercept is negative Quadrant III, because the slope is negative and the y-intercept is positive Quadrant IV, because the slope is positive and the y-intercept is negative

Answers

The graph will not pass through quadrant II, because the slope is positive and the y-intercept is negative. The correct option is B.

What is a linear function?

The word "linear function" in mathematics refers to two different but related ideas: In calculus and related fields, a linear function is a function whose graph is a straight line, i.e., a polynomial function of degree zero or one.

Given function is y = ( -6 + ( 2 / 3 ) x. By plotting the graph on the coordinate axis it is observed that the graph of the function passes through the first third and fourth quadrants.

The coordinates of the graph cutting on the x and y axis are ( 9, 0 ) and ( 0, -6). The graph of the linear equation is attached with the answer below.

Therefore, the graph will not pass through quadrant II, because the slope is positive and the y-intercept is negative. The correct option is B.

Answer:

Quadrant II, because the slope is positive and the y-intercept is negative, I just took the test.

Step-by-step explanation:

Write a story problem using mixed numbers that need to be scaled up. The problem should
have at least five mixed numbers that will be scaled up. Be sure to show all your work, explain your
steps in your solution (including changing improper fractions to mixed numbers), and write a complete
answer to your problem. Your answer should include units for the mixed numbers, if needed.

[Insert generic name here] is trying to bake a yellow cake because [reasons]. This recipe will make one whole cake.

3(1)/(4)\ cups\ of\ flour\n 2(1)/(2)\ teaspoons\ of\ baking\ soda\n (1)/(2)\ teaspoon\ of\ salt \n 1(3)/(4)\ cups\ of\ sugar \n (2)/(3)\ cup\ of\ butter \n 2\ eggs\n 1(1)/(2)\ teaspoons\ of\ vanilla\ \n 1(1)/(4)\ cups\ of\ milk

He wants to make three cakes instead of one. How much of each item should be used in the new (scaled-up) recipe?

3(1)/(4)*3=9(3)/(4)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ cups\ of\ flour\n 2(1)/(2)*2=4(2)/(2)=4+1=5\ \ \ \ \ teaspoons\ of\ baking\ soda\n (1)/(2)*3=(3)/(2)=1(1)/(2)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ teaspoons\ of\ salt \n 1(3)/(4)*3=3(9)/(4)=3+2(1)/(4)=5(1)/(4)\ cups\ of\ sugar

(2)/(3)*3=(6)/(3)=2\ \ \ \ \ \ cups\ of\ butter\n 2*3=6 \ \ \ \ \ \ \ \ \ \ \ \ eggs\n 1(1)/(2)*3 = 3(3)/(2) = 4\frac{1}2\ teaspoons\ of\ vanilla\ \n 1(1)/(4)*3=3(3)/(4)\ \ \ \ \ \ \ \ cups\ of\ milk

I don't know exactly how your teacher wants you to write out the work, but I have it pretty simple there. It's not like math is tailored to a specific process; any sort of reasonable work should do.

Good luck!
