Answer:

Jill paid $225 and cindy paid $75.

Step-by-step explanation:

From the information given, you can say that the price of Jill's jacket plus the price of Cindy's jacket is equal to 300:

x+y=300 (1), where:

x is the price of Jill's jacket

y is the price of Cindy's jacket

Also, you know that Jill bought a jacket that cost 3 times as much as cindy, which would be:

x=3y (2)

Now you can replace (2) in (1) and solve for y:

3y+y=300

4y=300

y=300/4

y=75

Finally, you can replace the value of y in (2) to find x:

x=3y

x=3*75

x=225

According to this, the answer is that Jill paid $225 and cindy paid $75.

Answer:

See below.

Step-by-step explanation:

There are 12 months in 1 year.

Since her balance changes -$2,931 is 1 year, it changes 1/12 of that amount in 1 month.

1/12 * -$2,931 = -$2,931/12 = -$244.25

The change each month is -$244.25

The change in 1 month is found by dividing the change in 1 year by 12 since there are 12 months in 1 year.

In 6 months, the change is 6 times the change in 1 month.

6 * -$244.25 = -$1,465.50

The change in 6 months is -$1,465.50

The lines intersect at ( 7, 14). Days are along the x axis, so they have the same amount on day 7.  

Answer:

Step-by-step explanation:

[tex]y=-2sin (\frac{2\pi (t+1)} {7})+5\\Height ~is~maximum~\\if sin (\frac{2\pi (t+1)}{7} )=-1\\or~ \frac{2\pi (t+1)}{7} =\frac{3 \pi }{2} \\t+1=\frac{3\pi }{2} \times \frac{7}{2\pi } =\frac{21}{4} \\t=\frac{21}{4} -1=\frac{17}{4} =4.25 ~seconds.[/tex]

The weight reaches its maximum height at 4.25 seconds.

'The maximum height of the object is the highest vertical position along its trajectory.'

According to the given problem,

y = -2sin ([tex]\frac{2\pi ( t + 1 )}{7}[/tex]) + 5

For maximum height,

  sin ([tex]\frac{2\pi ( t + 1 )}{7}[/tex]) = -1

⇒ [tex]\frac{2\pi ( t + 1 )}{7}[/tex] = [tex]sin^{-1} (-1)[/tex]

⇒  [tex]\frac{2\pi ( t + 1 )}{7}[/tex] = [tex]\frac{3\pi }{2}[/tex]

⇒ [tex]t +1=\frac{7 * 3\pi }{2 *2\pi }[/tex]

⇒ [tex]t +1[/tex] = [tex]\frac{21}{4}[/tex]

⇒ [tex]t = \frac{21}{4} -1[/tex]

⇒ t = [tex]\frac{17}{4}[/tex]

⇒ t = [tex]4.25[/tex] seconds.

Hence, we can conclude that at t = 4.25 seconds, the weight reaches its maximum height.

Answer:

Answer:

2y = 3x-1

Step-by-step explanation:

We start by calculating the slope of AB

m = (y2-y1)/(x2-x1) = (2-5)/(4-6) = 3/2

Since the two lines are parallel, then their slopes are equal

We use the point-slope form to get the equation

That will be;

y-y1 = m(x-x1)

y-10 = 3/2(x-7)

y = 3x/2-21/2+ 10

Multiply through by 2

2y= 3x -21 + 20

2y = 3x-1

Answer:

x = 108

Step-by-step explanation:

The angles all add up to 180 degrees, so if you subtract 25 and 47 from 180, you get x.

we know that the triangle is always going to be 180 degrees so add up 25 + 47 = 72

Now 180 - 72 = 108

108 is the answer :)

Answer:

The slope is -0.23. This means that the power decreases by 23% per hour.

Step-by-step explanation:

Given the function y=-0.23x+1 that represents the percent y (in decimal form) of battery power remaining x hours after you turn on a laptop computer, we are to identify and interpret the slope

The standard form of equation of a line is expressed as y = mx+c

m is the slope

c is the intercept

On comparison, you will see that;

-0.23x= mx

-0.23 = m

rearrange

m = -0.23

Hence the slope is -0.23

Since the slope is negative, it shows that the power decreases by 23% per hour (0.23 = 23%)

The proofing that ABCD is a parallelogram can be done through the parallelogram side theorem.

It should be noted that parallelogram side theorem simply means that the opposite sides of a parallelogram are equal and also parallel to each other.

Here, BCA and DAC are alternate interior angles. Also, AC denotes the reflexive property. Therefore, BC is the same as DA ast they're equal.

Additive Inverse = 1/2

Multiplicative Inverse = -2

========================================

Explanation:

The additive inverse of x is -x. The two add to 0.

So the additive inverse of -1/2 is 1/2 because -1/2+1/2 = 0.

--------------

The multiplicative inverse of x is 1/x

More thoroughly, the multiplicative inverse of a/b is b/a.

We apply the reciprocal operation here.

That means the multiplicative inverse of -1/2 is -2/1 which simplifies to -2.

We can see that (-1/2)*(-2) = 1

Any nonzero value multiplied with its multiplicative inverse will always result in 1.

Answer:

1. Additive Inverse = [tex]\frac{1}{2}[/tex]

2. Multiplicative Inverse = -2

Step-by-step explanation:

An "additive inverse" refers to the number that is being added to another number in order to arrive at a sum of zero (0).

The additive inverse of -[tex]\frac{1}{2}[/tex] is [tex]\frac{1}{2}[/tex] because when you add both numbers, the sum is 0.

A "multiplicative inverse" refers to the number that is being multiplied to another number in order to arrive at a product of 1.

The multiplicative inverse of -[tex]\frac{1}{2}[/tex] is -2 because when you multiply both, the product is 1.

Answer:

The option 'b' is true.

Step-by-step explanation:

Given the expression

[tex]f\left(x\right)=\frac{2}{x+7}[/tex]

A function g is the inverse of the function f if for y=f(x), x=g(y)

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

Replace x with y

[tex]\:x=\frac{2}{y+7}[/tex]

solve for y

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

Thus,

[tex]f^{-} (x)=\frac{-7x+2}{x}[/tex]

Therefore, option b is true.

x² + y² - 6x + 4y + 12 = 0

Answer:

Please check the explanation below.

Step-by-step explanation:

Some of the properties are defined as:

a(b+c) = ab+ac

For example,

suppose a=1, b=2, c=3

1(2+3) = 1(2) + 1(3)

5 = 2+3 = 5

if (a=b), then a-c = b-c

For example,

suppose a=1, b=1, c=3

if a = b ⇒ 1 = 1

then a-c = b-c ⇒ 1-3 = 1 - 3  ⇒ -2 = -2

if (a=b), then a+c = b+c

For example,

suppose a=1, b=1, c=3

if a = b ⇒ 1 = 1

then a+c = b+c ⇒ 1+3 = 1+3  ⇒ 4 = 4

if (a=b), then a×c = b×c

For example,

suppose a=1, b=1, c=3

if a = b ⇒ 1 = 1

then a×c = b×c ⇒ 1×3 = 1 × 3  ⇒ 3 = 3

if (a=b), then a÷c = b÷c

For example,

suppose a=1, b=1, c=3

if a = b ⇒ 1 = 1

then a÷c = b÷c ⇒ 1÷3 = 1 ÷ 3  ⇒ 1/3 = 1/3

Let's solve the given equation using the above properties.

5(x+10) = 20        Given

5x+50 = 20          1) Distriburive property ∵ a(b+c) = ab+ac

5x = -30               2) Subtraction property of Equality ∵ if (a=b), then a-c = b-c

x = -6                    3) Division property of Equality  ∵ if (a=b), then a÷c = b÷c
