Answer:

a. 8.7cm

b. 43.5cm squared

Step-by-step explanation:

a. draw the triangle with a side length of 10cm, and measure the height which is 8.7cm.

b. formula to find the area  of a triangle: (base into height) divided by 2 ((b x h) / 2)

the base is 10

the height is 8.7

(10 x 8.7)/2 = 87/2 = 43.5 cm squared

Which of the following equations could represent the points in the table? Select all that apply.
schepotkina [342]

Answer:

Options (A) and (C)

Step-by-step explanation:

From table attached,

Let the equation of a linear equation that represents the input-output values in the table is,

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

Where (x', y') is a point lying on the graph.

And m = slope of the line passing through two points (x_1,y_1) and (x_2,y_2)

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

Slope of the line passing through (0, 11) and (1, 5) will be,

m = \frac{11-5}{0-1}

m = -6

Therefore, equation of the line passing through (0, 11) and slope = -6 will be,

y - 11 = -6(x - 0)

Equation of a line passing through (1, 5) and slope = -6 will be,

y - 5 = -6(x - 1)

Equation of a line passing through (2, -1) and slope = -6 will be,

y + 1 = -6(x - 2)

Equation of a line passing through (3, -7) and slope = -6 will be,

y + 7 = -6(x - 3)

Therefore, Options (A) and (C) are the correct options.

If x=3 then y=21. What is the value of x when y=105
NARA [144]

Answer:

0.6

Step-by-step explanation:

If Y=105 you would divide 105 by the original Y which was 21, therefore getting 5. With that 5 we would divide 3 by 5 because that's what we did with the Y and then we get 0.6. hope this helped! xx
