Answer:

A. All rectangles are parallelograms. Parallelograms have 2 pairs of parallel sides. Therefore, all rectangles have 2 pairs of parallel sides.

Step-by-step explanation:

Rectangles are parallelograms since they have 2 pairs of parallel sides.  All rectangles also have 4 right angles and 2 pairs of opposites sides that are of equal lengths.

Solve the equation -7(2m-6) + 21=-77
Svetllana [295]

Answer:

m=10

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−7(2m−6)+21=−77

(−7)(2m)+(−7)(−6)+21=−77(Distribute)

−14m+42+21=−77

(−14m)+(42+21)=−77(Combine Like Terms)

−14m+63=−77

−14m+63=−77

Step 2: Subtract 63 from both sides.

−14m+63−63=−77−63

−14m=−140

Step 3: Divide both sides by -14.

-14m/-14=-140/-14

m=10

Which inequality represents all values of x for which the quotient below is
Vika [28.1K]

Answer: -2 \le x < 5

========================================================

Explanation:

We cannot have negative numbers under the square root, if we wanted the result to be some real number.

The stuff under the square root must be 0 or larger.

This means the x+2 must be 0 or larger.

x+2 \ge 0\\\\x \ge -2

Similarly, the 5-x must be 0 or larger. But wait, we cannot have 0 in the denominator (or else we have a division by zero error), so 5-x must be larger than 0.

5-x > 0

5-x+x > 0+x

5+0 > 0+x

5 > x

x < 5

Combine both x \ge -2 and x < 5 to find the domain is -2 \le x < 5

--------------------------------------------------------

Visual confirmation is shown below. I used Desmos which is a free graphing app.

  • f(x) = sqrt(x+2) is in red
  • g(x) = sqrt(5-x) is in blue
  • h(x) = f(x)/g(x) is in green

The green curve is what we're after. It's between x = -2 and x = 5

We include -2, but exclude 5.

Take note of the closed endpoint at x = -2, and also the vertical asymptote at x = 5. The curve approaches this asymptote but never actually touches it. Think of an electric fence you can get closer to, but not actually touch.
