What is the equation of the line that is paralle to y=3x-8 and passes thur the point (4,-5)

Brrunno [24]

⊰_________________________________________________________⊱

Answer:

The equation is-: y=3x

Step-by-step explanation:

$\large\displaystyle\text{$\begin{gathered} \sf{Substitute \ the \ values \ into \ the \ formula \ y-y_1=m(x-x_1)} \\ \sf {parallel \ lines \ have \ same \ slopes, \ thus} \\ \sf{slope \ of \ the \ 2nd \ line = 3}\\ \sf{now \ substitute \ the \ values} \\ \sf {y-(-5)=3(x-4)}\\ \sf{y+5=3(x-4) (It's \ Point-Slope\;Form, \ see \ below \ for \ slope-intercept)}\\ \sf {y+5=3x-12} \\ \sf{y=3x-12-5} \\ \sf{y-3x-17} \end{gathered}$}}$

26. A single card is drawn from a deck. Find the probability that the card is either red or a face card.

Lana71 [14]

Answer:

8/13

Step-by-step explanation:

There are total 26 red cards in the deck of 52 cards.

There are also 12 face cards in the deck ( which is 6 of them are red, while 6 of them are black)

Since we only need either one of them, 26 + 6 = 32

The probability of drawn a card that either red or a face card is 32/52

The simplest form of this fraction is 8/13.

An angle measures 14° more than the measure of its supplementary angle. What is the measure of each angle?

luda_lava [24]

Answer:83 and 97

Step-by-step explanation:

Let the angle be y

The second angle will be y+14

A supplementary angle equals 180°

y + y + 14=180

2y+14=180

2y=180-14

2y=166

y=166/2

y=83

The first angle is 83.

Second angle will be 83+14=97.
