Answer: The slope is -2/7.

Step-by-step explanation:

The formula to find the slope is y₂ - y₁ / x₂ - x₁.

So, you can take any 2 points on the table.

For instance, (0, 4) and (7, 2).

Plug these points into the formula.

2 - 4 / 7 - 0 = -2/7

Draw a triangle that satisfies this condition: The ratio of the interior angles is 7:11:12

denpristay [2]

The sum of the interior angles of a triangle is 180 degrees.
1.) Translating the problem into equation:
7:11:12 = 180 degrees
7x+11x+12x = 180 degrees; Where x = missing number
30x = 180
30x/30 = 180/30 divide both sides by 30
x = 6
2.) Substitute the values:
7x+11x+12x = 180
7(6)+11(6)+12(6) = 180
42+66+72 = 180
180 = 180
3.) Therefore, the angles should be 42 degrees, 66 degrees and 72 degrees.
4.) See attached drawing of triangle

70 POINTS! ∆ABC is reflected across the x-axis, then rotated 90° clockwise about the origin, and finally reflected across the li

Answer:

A'(1, 1); B'(3, 2); C'(1, 2)

Step-by-step explanation:

The original points are A(1,1 ), B(2, 3) and C(2, 1).

Reflecting the triangle across the x-axis will negate every y-coordinate; this maps

(1, 1)→(1, -1); (2, 3)→(2, -3); (2, 1)→(2, -1)

Rotating the figure 90° clockwise about the origin switches the x- and y-coordinates and negates the x-coordinate; this maps

(1, -1)→(-1 -1); (2, -3)→(-3, -2); (2, -1)→(-1, -2)

Reflecting across the line y=x will negate both the x- and y-coordinates; this maps

(-1, -1)→(1, 1); (-3, -2)→(3, 2); (-1, -2)→(1, 2)

Is the product of x-4 and 5x^2-3x+6 equal to the product of x+4 and -5x^2+2x-6?

suter [353]

Answer:

Not equal

Step-by-step explanation:

To find if they are equal, find the product of each first by multiplying each term using exponent rules.

$(x-4)(5x^2-3x+6) \\\\5x^3 -20x^2 - 3x^2 + 12x + 6x - 24\\\\ 5x^3 - 23x^2 + 18x - 24$

and

$(x+4)(-5x^2+2x-6)\\\\-5x^3 - 20x^2 + 2x^2+8x-6x-24\\\\-5x^3-18x^2 +2x - 24$

These expressions are not the same.
