Answer:

Y=3

X=9/5

Step-by-step explanation:

(1) 5x=y+6

(2) 5x+2y =3

Replace (1) to (2) => (y+6)+2y=3 => y=3

Replace y=3 to (2) => 5x = 3+6 => 5x=9 => x=9/5

Answer:

(-3,-1)

Step-by-step explanation:

6x-12y=-6

6x=12y-6

x=2y-1

9(2y-1)-6y= -21

18y-9-6y=-21

12y= -12

y=-1

6x-12(-1)=-6

6x+12= -6

6x=-18

x=-3

Answer:

x = -3 ; y = -1

Step-by-step explanation:

Let 9x - 6y = -21 be eqn.1 & let 6x - 12y = -6 be eqn.2 .

Lets find the value of x from eqn.1

[tex]9x - 6y= -21[/tex]

[tex]=> 3(3x - 2y) = -21[/tex]

[tex]=> 3x - 2y = \frac{-21}{3} = -7[/tex]

[tex]=> x = \frac{2y - 7}{3}[/tex]

Now , lets put the value of x (which we got from eqn.1) in eqn.2 :-

[tex]6x - 12y = -6[/tex]

[tex]=> 6(x - 2y) = -6[/tex]

[tex]=> x - 2y = \frac{-6}{6} = -1[/tex]

(Putting x here)

[tex]=> \frac{2y - 7}{3} - 2y = -1[/tex]

[tex]=> \frac{2y - 7 - 6x}{3} = - 1[/tex]

[tex]=> -4 y - 7 = -1 \times 3 = -3[/tex]

[tex]=> -4y = 7 - 3 = 4[/tex]

[tex]=> y = \frac{-4}{4} = -1[/tex]

Now , lets find the value of x.

[tex]x = \frac{2y - 7}{3}[/tex]

Putting y = -0.5 gives ,

[tex]x = \frac{[2 \times (-1)] - 7}{3}[/tex]

[tex]=> x = \frac{-2 - 7}{3} = \frac{-9}{3} = -3[/tex]

Answer:

5.5

Step-by-step explanation:

Sales tax = tax rate × Cost of meal

Sales tax = $1.32

Tax rate = x%

Cost of meal = $24

Sales tax = tax rate × Cost of meal

1.32 = x% × 24

1.32 = x/100 × 24

1.32 = 24x/100

1.32 * 100 = 24x

132 = 24x

x = 132/24

x = 5.5%

= 5.5

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

The formula for doubling time is given as:

P(t) = Po(2)^t/k

Where:

P(t) = Population after time t = 28,284

Po = Initial Population = 20,000

t = time = 3 days

k = doubling time = ?

28,284 = 20,000 × (2)^3/k

Divide both sides by 20,000

28,284/20,000 = 20,000/20,000 × (2)^3/k

1.4142 = (2)^3/k

2^1/2 = (2)^3/k

Divide both sides by 2

1/2 = 3/k

Cross Multiply

k × 1 = 2 × 3

k = 6

Therefore, the doubling time(k) of the bacteria is 6

Answer:

169.2 is 132.1875% of 128

Step-by-step explanation:

The required number next number in the sequence is 27.

Given that,
Sequence = 55, 48, 41,34, the number that comes next in the sequence is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

here,
Given sequence,
55, 48, 41, 34
The sequence has a common difference of 7,
When we subtract 7 from the number 34, the next number in the sequence can be calculated,
So.
next number = 34 - 7 = 27

Thus, the required number next in the sequence is 27.

Answer:

-3 is a constant.

Step-by-step explanation:

The given equation is :

4x+5y-3 ...(1)

The general equation is :

ax+by+c ...(2)

c is a constant

If we compare equations (1) and (2), we find that.

c=-3

Hence, the constant in this expression is -3.

Answer and explanation:

Given the above, we find y in terms x

change in y change in x = 0.5

The formula for a straight line is y= mx+b where m is slope of the line and b is the y intercept

We substitute given values above in the straight line equation:

y=mx+b

1.5= 0.5×3+b

1.5=1.5+b

b= 0

y in terms of x for the line is therefore given by the formula :

y=0.5x+0

Answer: Perpendicular

Step-by-step explanation:

Answer: um what do u mean?

Answer:

a) The y-intercept is 160. It represents the initial distance Jayden was from his home.

b) The x-intercept is 4. It represents the amount of time taken for Jayden to reach his home.

Step-by-step explanation:

The y-intercept can be found by looking at the value of y when x=0. When x=0, y= 160. Since the x-axis is the amount of time in hours, x=0 would mean the initial time. The x-axis is the number of miles from Jayden's home thus, Jayden was 160 miles away from his home when x=0 hours.

The x-intercept can be found by looking at the x value when y=0. When y=0, x=4. This means that it took Jayden 4 hours to reach home or 4 hours to travel 160miles to his house.
