What values of x and y satisfy the system of equations 10x=5y−8 15x=−5y−2?

the equation of the line that has a slope of 1/5 and passes through (-5, -6) is: y = 1/5x - 5.

Given that the line passes through (-5, -6), and has a slope (m) = 1/5, to find the equation of the line, do the following:

Substitute (x, y) = (-5, -6) and m = 1/5 into y = mx + b to find the value of b:

-6 = 1/5(-5) + b

-6 = -1 + b

Add 1 to both sides

-6 + 1 = -1 + b + 1

-5 = b

b = -5

Substitute m = 1/5 and b = -5 into y = mx + b

y = 1/5x + (-5)

y = 1/5x - 5

Thus, the equation of the line that has a slope of 1/5 and passes through (-5, -6) is: y = 1/5x - 5.

When Todd says that he used 718 feathers to make the cat toys, it does not sound right.

To solve this problem, we have to state the equations using the information of the problem

Information about the problem:

Calculating how many feathers Todd should use to made 198 cat toys:

Total feathers = No. of toys * No. feather per toy

Total feathers = 198 toys  * 6 feather/ toy

Total feathers = 1188 feathers

With the calculate we can confirm that Todd's calculate is not right because:

Total feathers > Todd's calculated

1188 feathers > 718 feathers

Answer:

a

Step-by-step explanation:

the complement of R is 90 - R , then

R = 5(90 - R) - 6

R = 450 - 5R - 6

R = 444 - 5R ( add 5R to both sides )

6R = 444 ( divide both sides by 6 )

R = 74°

complement = 90° - 74° = 16°

Option(a) 16 is correct option, the measure of the complement of R is 16

Two angles are complementary if their sum is 90°.

Let x be an angle and y be its complement of x then x + y = 90°.

Let the measure of the complement of R be x

Given that the measure of angle R is 6 less than 5 times its complement

Then 5 times the complement of R = 5x

And 6 less than 5 times the complement of R  = 5x-6

Thus, R = 5x -6

∴ R + complement of R = 90°

⇒5x-6 + x = 90

⇒6x = 96

⇒x = 96/6 = 16

Therefore, the measure of the complement of angle R is 16 and option (a) is correct option.

Darla can spend the greatest total cost of groceries in order to spend as close to $15 as possible is approximately $14.20.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Let the cost of the groceries be represented as "c", then we have;

Cost price + VAT = c + (5% of c)

In order to get the cost, c, that make him spend as close to $15. Since the tax is 5% of the cost price, then the cost price will be close to $15.

Let c = $14.20, then;

So that,

c + (5% of c) = 14.20 + (5% of 14.20)

                   = 14.20 + 0.71

                   = $14.91

Step-by-step explanation:

When a point is rotated 180° about the origin(either clockwise or anticlockwise), the transformed coordinates are the negatives of the original coordinates.

Thus when a point (x, y) is rotated about the origin, its new coordinates become (-x, -y)

Original Vertex    ==>     Transformed Vertex

Step-by-step explanation:

The formula for annual compound interest, including principal sum, is:

A = P (1 + r/n) (nt)

where

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested or borrowed for

here

we have to found semianually

P= 2000

r= 11% =0.11

n=2   .... for semiannual

t =5

A = 2000( 1 +0.11 /2 )(2*5)

The area of a rectangular cement walkway of width x meters around a 50m by 25m pool is 4x²+150x sq. meters.

Rectangle area in geometry refers to the area that a rectangle occupies on a two-dimensional plane. A rectangle is a form of a quadrilateral, a two-dimensional object with four sides and four vertices. The four angles of the rectangle are all perfectly right angles or 90 degrees. The opposing sides of the rectangle are equal and parallel.

Area of Rectangle = Length × Breadth

In the given question,

The width of the walkway is x meters.

Width of the pool= 25+2x meters

and the Length= 50+2x.

So the area of the walkway with the pool is

= (25+2x)+(50+2x)

= 1250+100x+50x+4x²

= 4x²+150x+1250 sq. m

Area of the pool= 50x25

= 1250 sq. m

Area of the walkway= 4x²+150x+1250-1250

= 4x²+150x sq. meters.

Hence, the answer is 4x²+150x sq. meters.

The simplification of the given logarithmic functions ln (2x-1)² = 7 is 17.055.

The logarithm of a number is the exponent by which a fixed value referred as the base should always be raised to generate a certain number. For instance, because 1000 is 10 to the third power, a log of 1000 to base 10 is 3.

Some properties of the logarithmic functions are defined as-

As, for the stated log or ln function ln (2 x-1)²=7

Use the power rule on the left side of the equation.

2 ln (2 x-1) = 7

Simplifying the equation.

ln (2 x-1) = 7/2

ln (2 x-1) = 3.5

Using the exponential property of the log.

e∧[ln (2 x-1)] = e∧3.5

2x-1 = 33.11

2x = 33.11 + 1

2x = 34.11

x = 34.11/2

x = 17.055

Therefore, the value of the x for the stated logarithmic functions ln (2x-1)² = 7 is calculated as 17.055.

The correct option is (x²- 2x + 4) for the quotient.

For the given question;

The equations are given as;

(x³ + 8) = (x + 2)

For finding the quotient; this could be written as,

(x³ + 8)/ (x + 2) = 1

Thus, we have

= (x³ + 8)/ (x + 2)

Rewriting the equation as;

=  (x³ + 2³)/ (x + 2)

Apply the formula of (a³ + b³) = (a+b)(a² - ab + b²) at the numerator;

= (x + 2)(x² -2x + 4)/  (x + 2)

Cancel the value of (x+ 2)

Answer: 1.7

Step-by-step explanation:

The answer to the present question is: log(a²b³/c⁴) = 2log(a) + 3log(b) - 4log(c)

For solving this kind of question, we are going to use these three identities:

log(x*y) = log(x) + log(y)   ....(1)

log(x/y) = log(x) - log(y)    ....(2)

log(xⁿ) = nlog(x)                ....(3)

So, using (2), log(a²b³/c⁴) may be written as: log(a²b³) - log(c⁴)  ....(4)

Again, using (1), log(a²b³) are often written as: log(a²) + log(b³)  ....(5)

Now, Putting equation (4) in equation (3), we get:

log(a²) + log(b³) - log(c⁴)   ....(5)

Now, using (3), expanding all the terms, we get:

log(a²) = 2log(a)log(b³) = 3log(b)log(c⁴) = 4log(c)

Putting of these in equation 5, we get:

2log(a) + 3log(b) - 4log(c)

Therefore,  log(a²b³/c⁴) = 2log(a) +3log(b) - 4log(c)

Given that;

Christopher bought stock in a company two years ago that was worth xx dollars.

In the first year that he owned the stock, then it decreased by 11%.

In the second year the value of the stock decreased by 27%.

Now,

The multiplier of value for the first year was (1 - 11%) = 0.89

The multiplier of value for the second year was (1 - 27%) = 0.73

Then the multiplier of value for the two years was = 0.89 * 0.73

Here, we have,

To represent the addition expression (-3) + (-1) on a number line,

we would start at -3 and move to the left by 1 unit.

Here's how we can explain it step by step:

Start at -3 on the number line.

Since we have a negative sign in front of both numbers, we will move to the left (in the negative direction) on the number line.

The first number, -3, indicates that we will start at -3 on the number line.

The second number, -1, indicates that we will move to the left by 1 unit from -3.

When we move to the left from -3 by 1 unit, we will reach -4 on the number line.

So, (-3) + (-1) represented on the number line means starting at -3 and moving to the left by 1 unit, resulting in -4.
