Y=3x-5
3y-12x=-6
Substitution method

Answers

Answer 1

Answer: Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is 3x−5.
y=3x−5
3(3x−5)−12x=−6

Simplify each term.
y=3x−5
9x−15−12x=−6

Add 9x and −12x to get −3x.
y=3x−5
−3x−15=−6

move -15 to the right-hand side of the equation by adding 15 to both sides.
y=3x−5
−3x=15−6

Subtract 6 from 15 to get 9.
y=3x−5
−3x=9

Simplify

(−3,−14)

Answer 2

Answer: 1y = 3x - 5 ⇒ 1y - 3x = - 5 ⇒ 3y + 9x = 15
3y - 12x = -6 ⇒ 3y - 12x =   6 ⇒ 3y - 12x = 6
       21x = 21
      21    21
   x = 1
      y - 3(1) = -5
          y - 3 = -5
   +3   +3
   y = 2
   (x, y) = (1, 2)

Slope
y = ⁸/₉x - 3¹/₃
The slope is ⁸/₉.

Y - Intercept
y = ⁸/₉x - 3¹/₃
y = ⁸/₉(0) - 3¹/₃
y = 0 - 3¹/₃
y = -3¹/₃
The y-intercept is -3¹/₃

The answer is C.

Answer:

C. The slope is 8⁄9 and the y-intercept is -3⅓ [or -10⁄3].

Step-by-step explanation:

According to the Slope-Intercept Formula, y=mx+b,bis your y-intercept, so that is a giveaway. Now, your rateofchange[slope], which is represented by m,is the coefficient, meaning the term in front of x,so that is also a giveaway.

b. 1/9900
c. 1/4950
d. 2/100
need right now please

Answers

Answer: Hello mate!

There are 100 students, and each one has the same probability of being selected, which is 1/100

The chances that the band leader selects you is 1/100

now the chances that the band leader selects your brother is one over the total number of people in the band, but you have already been selected, so there are 99 people right now in the band, this probability is of 1/99.

The joint probability of both events is the product of the probabilities, this is:

P = (1/100)*(1/99) = 1/9900

But there is also the chance where your brother is picked first and you second, which also has a probability of 1/9900.

Then the total probability of you and your brother to being selected is:

P = 1/9900 + 1/9900 = 2/9900 = 1/4950

te right option is option C.

That probability is 1/4950 .

Rick rents a car from a company that charges him $25 per day plus 10 cents per mile driven. Which expression can represent the amount he owed on a recent rental?a.) 25x + 0.1y
b.) 251.x
c.) 25.1xy
d.) 25.1 + 35y

Answers

Let x be the number of days and y represent miles driven.

Since it costs 25 per day, you multiply 25 by x.
25x

10 cents (otherwise known as .1 dollars) per mile, multiply .1 times y. Now add the two.
.1y

25x+.1y

The answer is a.) 25x + 0.1y.
