For the graph x = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an

scoray [572]

Lines that are perpendicular to another line has an opposite reciprocal slope. (opposite meaning to negate the number).
Lines that are parallel have the same slope.

But the line you provided is a vertical line, and vertical lines are undefined. There is no possible perpendicular or parallel line. Maybe you gave the wrong equation and didn't put it in y=mx+b form. If so, you can correct it in the comments, and if not, that's you answer!

Help with this and show steps, please!!!!!!

kipiarov [429]

Answer:

Step-by-step explanation:

The figure has two disjoint pairs of consecutive sides which are congruent.

Thus the figure is a Kite

Using the properties of a Kite

• The diagonals are perpendicular

• The main diagonal diagonal bisects the pair of opposite angles

Hence ∠1 = 90° ( diagonals are perpendicular )

The angle 22° is a bisected angle so the angle below is also 22°

The sum of the 3 angles in a triangle = 180°, hence

∠2 = 180° - (90 + 22)° = 180° - 112° = 68°

The solution is A

Write an equation for a line that is parallel to the graph of y = -3x + 6 and passes through the point at (-4, 7)

ale4655 [162]

Y = -3x + 6....the slope here is -3. A parallel line will have the same slope.

y = mx + b
slope(m) = -3
(-4,7)....x = -4 and y = 7
now we sub into the formula and find b, the y int
7 = -3(-4) + b
7 = 12 + b
7 - 12 = b
-5 = b
so ur parallel equation is : y = -3x - 5 <==

A supplier delivers an order for 20 electric toothbrushes to a store. By accident, three of the electric toothbrushes are defect

krek1111 [17]

Answer:

The probability that the first two electric toothbrushes sold are defective is 0.016.

Step-by-step explanation:

The probability of an event, say E occurring is:

$P (E)=\frac{n(E)}{N}$

Here,

n (E) = favorable outcomes

N = total number of outcomes

Let X = number of defective electric toothbrushes sold.

The number of electric toothbrushes that were delivered to a store is, n = 20.

Number of defective electric toothbrushes is, x = 3.

The number of ways to select two toothbrushes to sell from the 20 toothbrushes is:

${20\choose 2}=\frac{20!}{2!(20-2)!}=\frac{20!}{2!\times 18!}=\frac{20\times 19\times 18!}{2!\times 18!}=190$

The number of ways to select two defective toothbrushes to sell from the 3 defective toothbrushes is:

${3\choose 2}=\frac{3!}{2!(3-2)!}=\frac{3!}{2!\times 1!}=3$

Compute the probability that the first two electric toothbrushes sold are defective as follows:

P (Selling 2 defective toothbrushes) = Favorable outcomes ÷ Total no. of outcomes

$=\frac{3}{190}\\$

$=0.01579\\\approx0.016$

Thus, the probability that the first two electric toothbrushes sold are defective is 0.016.
