what is the value of y in the following system?
y=3x-5
6x+3y=15

Answers

Answer 1

Step-by-step explanation:

y=3x-5

6x+3y=15

6x+3(3x-5)=15

6x+9x-15=15

15x-15=15

+15 +15

15x=30

/15. /15

x=2

6(2)+3y=15

12+3y=15

-12. -12

3y=3

/3 /3

y=1

(2,1)

The answer is (2,1)

Answer 2

Step-by-step explanation:

6x + 3(3x - 5) = 15

6x + 9x - 15 = 15

15x - 15 = 15

+15 +15

15x = 30

/15 /15

x = 2

6(2) + 3y = 15

12 + 3y = 15

-12 -12

3y = 3

Hazelhas$100inasavingsaccountthatearns10%interestperyear.Theinterestisnotcompounded.Howmuchwillshehavein1year? Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

Answers

Answer: See explanation

Step-by-step explanation:

Interest = PRT

Principal = $100

Rate = 10%

Time = 1 year

Interest = PRT = (100 × 10% × 1)

= 100 × 0.1 × 1

Interest = $10

Amount = Principal + Interest

= $100 + $10

= $110

Answer:

a) 94°

Step-by-step explanation:

shape is a 5-sided polygon, known as a pentagon

number of degrees inside can be found by taking the number of sides (5), deducting 2 (3) and then multiplying by 180°.

Therefore there are 540° altogether.

add all like terms for all five angles:  24x - 12 = 540

                                                             24x = 552

                                                               x = 23

m∡P = 4(23) = 2

         = 92 + 2

The answer to this question is 32

Explanation

16/30 cross multiplies x/60

after you get, 960=30x

then divide by 30 and then you get 32.

or you can just take 16 and multiply it by two since 60 is a multiple of 30.

Aiden cuts a ball of string into 14 equal pieces. The length of each piece of string is 2 1/4 yards. What is the original length of the ball of string?

Answers

Answer:

31 1/2 yards

Step-by-step explanation:

In order to calculate the original length of the ball of string we simply need to multiply the length of each piece of string by the total number of strings that were produced from the original ball of string. First, we can turn the 2 1/4 into a single decimal number. Since 1/4 is equal to 0.25 we just add this to 2 to get 2.25, now we can go ahead and multiply this by the 14 total pieces.

2.25 * 14 = 31.5 or 31 1/2 yards

c = 12/4

Answer:

[tex]g(h(-8)) = 119[/tex]

Hence, option B) is true.

Step-by-step explanation:

Given

g(x) = 2x-5

h(x) = x² - 2

To determine

[tex]g(h(-8)) = ?[/tex]

In order to determine g(h(-8)), first we need to determine h(-8), so

substituting x = -8 in h(x) = x² - 2

h(x) = x² - 2

h(-8) = (-8)² - 2

h(-8) = 64 - 2

h(-8) = 62

so we can write

[tex]g(h(-8)) = g(62)[/tex]

now, to determine g(62), substitute x = 62 in g(x) = 2x-5v

g(x) = 2x-5

g(62) = 2(62) - 5

g(62) = 124 - 5

g(62) = 119

so,

[tex]g(h(-8)) = g(62)=119[/tex]

Therefore,

[tex]g(h(-8)) = 119[/tex]

Hence, option B) is true.

A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.

Radius of a circle is the distance from the center of the circle to any point on it's circumference.

Here, SM=OM=7.4 units

Therefore, option B is the correct answer.

Let x represent the number of years in 2004 and y represent the number of catalogs Catalogs. Number in 2004. Growth rate Online. 7440. 1293 Print. 3805. -1364

Answers

Answer:

The answer is below

Step-by-step explanation:

a)  x represents the number of years since 2004 this means that x = 0 represent the year 2004, y represent the number of catalogs. From the table the numbers of catalogs in 2004 are y-intercepts and the slope is the growth rates. Hence the equations are:

y = 1293x + 7440           (1)

y = -1364x + 3805         (2)

b)

y = 1293x + 7440           (1)

y = -1364x + 3805         (2)

Subtract equation 2 from equation 1 to get:

0 = 2657x + 3635

2657x = -3635

Divide through by 2657

x = -1.368

Put x = -1.368 in equation 1:

y = 1293(-1.368) + 7440

y = 5671.1

This means that about 1.4 years before 2004, the number of catalogs where 5671

Cora went on a shopping trip to Lowell. She purchased a calculator originally priced at $75 but discounted 20%. If sales tax in Lowell is 15%, what was the total cost?

Answers

Answer: $69

Step-by-step explanation:

Sales tax is charged after the discount.

The calculator was originally $75 and there is a 20% discount.

The discounted price is:

= 75 * (1 - 20%)

= 75 * 0.8

= $60

Now the sales tax applies. Total cost is:

= 60 * (1 + 15%)

= 60 * 1.15

= $69
