Proportional reasoning is a form of mathematical reasoning that involves a sense of co-variation and of multiple comparisons, and the ability to mentally store and process several pieces of information. I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:

Proportional Reasoning is the ability to recognize when two rations are equivalent. Two ratios are said to be equivalent if the ratios have equal numerical values. That's the actual definition from the class itself and it gave me a 100% score. Hope this helps!

Answer:

$x=27$

Step-by-step explanation:

we know that

$(3x+9)^o+90^o=180^o$ ----> by supplementary angles (form a linear pair)

Solve for x

Combine like terms

$(3x+99)^o=180^o$

subtract 99 both sides

$3x=180-99\\3x=81$

Divide by 3 both sides

$x=27$

What rule would you allow to test weather (x,y) is on line l

n200080 [17]

Answer:

Step-by-step explanation:

If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.

Slope of a line passing through two points C(4, 5) and D(8, 10),

m = $\frac{y_2-y_1}{x_2-x_1}$

m = $\frac{10-5}{8-4}$

m = $\frac{5}{4}$

Equation of the line passing through C(4, 5) and slope m = $\frac{5}{4}$

y - y' = m(x - x')

y - 5 = $\frac{5}{4}(x-4)$

y = $\frac{5}{4}x-5+5$

y = $\frac{5}{4}x$

If point B(4, 0) lies on the line CD,

0 = $\frac{5}{4}(4)$

0 = 5

Which is not true.

Therefore, point B doesn't lie on line CD.
