Galina-37 [17]

Answer:

b) 94

Step-by-step explanation:

The Total Degree of a Triangle is 180 degrees. Knowing this, set up an equation.

68+26+x=180.

x is the complementary angle of the "?" angle.

Solve the equation.

94+x=180

x=86

Then Subtract 86 from 180 to find "?"

180-86=94

I hope this helps!

Compare the line passing through the points (−3, − 11) and (6, 4) to the line given by the equation y=32x−6.
butalik [34]

Answer:

See below

Step-by-step explanation:

<u>Given points:</u>

  • (-3, -11) and (6, 4)

<u>Let's calculate it's equation:</u>

  • y = mx +b
  • m = (4 + 11)/(6 +3) = 15/9 = 5/3
  • y = 5/3x + b
  • -11 = 5/3*(-3) + b ⇒ b = -11 + 5 = -6
  • y = 5/3x - 6

<u>The given line:</u>

  • y = 32x - 6

Compared, the lines have different slope (5/3 vs 32) but same y- intercept (-6), so both pass through the point of (0, -6). y= 32x - 6 has greater rate of change.

Two points defining a linear function are shown in the table below. x y –14 –18 –10 –12 What is the slope of the function? Two-t
Mazyrski [523]

Answer:

Option B.

Step-by-step explanation:

From the given table it is clear that the linear function passing through the points (-14,-18) and (-10,-12).

The slope of a linear function is

m=\dfrac{y_2-y_1}{x_2-x_1}

The given line passing through the points (-14,-18) and (-10,-12), so the slope of the line is

m=\dfrac{-12-(-18)}{-10-(-14)}

m=\dfrac{-12+18}{-10+14}

m=\dfrac{6}{4}

m=\dfrac{3}{2}

The slope of the required line is \dfrac{3}{2}.

Therefore, the correct option is B.
