What type of number is - v 81?

Answer:

-55.32

Step-by-step explanation:

I hope this helps!

Answer:

Well the number would have to be a negative number, because, no positive number can cause a smaller number adding a positive number will always cause a larger number.

So the answer is: $55.32+(-$55.32)

Adding the -55.32 causes it to even out meaning that u basically just added the debt of 55.32. This debt is causing an decrease in the amount of money she has. So really you are subtracting money

Answer:

y-4 = 4/9(x-10)

Step-by-step explanation:

Given the equation of the line g to be y = -9/4 x - 1.

To find the equation of a line h perpendicular to this line, the following steps must be taken;

First find the slope of the known line g

The standard equation of a line is y = mx+c where

m is the slope

c is the intercept

Comparing this equation with the given equation y = -9/4 x -1, it can be seen that the slope of the line g is -9/4

Next is to find the slope of the line h

Since the line g is perpendicular to h, then the product of their slope will be -1 i.e mh*mg = -1

mh = -1.mg

mh = -1/(-9/4)

mh = -1*-4/9

mh = 4/9

Hence the slope of the line h is 4/9

Find the intercept of line h

To get this, you will substitute the slope m and the point into the equation y = mx+c

m = 4/9

(x,y) = (10,4)

4 = 4/9(10) + c

4 = 40/9 + c

c = 4-40/9

c = (36-40)/9

c = -4/9

Hence the intercept of the line h is -4/9

Finally, find the equation of the line h in slope-intercept form

The slope-intercept form of a line is expressed as y = mx+c

y-y0 = m(x-x0)

Given

m = -4/9

x0 = 10

y0 = 4

Substitute:

y-4 = 4/9(x-10)

Hence the equation in slope-intercept form is y-4 = 4/9(x-10)

Given :

Price of cereal without off, C = $2.88 .

Percentage off, P = 20% .

To Find :

Price after applying 20% off.

Solution :

Final price = Initial price - 20 % of initial price

[tex]F = 2.88 - 2.88\times \dfrac{20}{100}\\\\F=2.88-0.576\\\\F=\$ 2.304[/tex]

Therefore, final price after sale is $2.304 .

Hence, this is the required solution.

Answer:

These types of angles are supplementary.

b. x + 75 +x +125 = 180

=> 2x = 180–200

=> 2x = –20

=> x = –20/2

=> x = –10

Bonus question:-

angle 1 = 48°

angle 2 = 180° –78°

= 102°

value of f :-

f + 48 + 102 = 180

=> f + 150 = 180

=> f = 180–150

=> f = 30°

Answer: 0.963

Step-by-step explanation:

The function used to determine the total amount a member pays for an item with regular price of x dollars is T (x) = 0.963x.

A discount is a reduction made from a regular or list price.

This is subtracted from the regular price of an item.

Now it is given that,

The function used to determine the price of an item after the 10% member discount,

f(x) = 0.9x,

where x is the regular price of the item.

The function used to determine the total amount customers Pay for a purchase after sales tax is applied.

g(x) = 1.07x

Now, total amount to be paid by customer for an item with regular price of x dollars

T(x) = regular price* discount * sales tax

⇒T(x) = x*0.9* 1.07

⇒T(x) = 0.963x

Hence, The function used to determine the total amount a member pays for an item with regular price of x dollars is T (x) = 0.963x.

The answer (y intercept) occurs when x = 0

The answer is -2

-5y = 10

y = 10/-5

y = - 2

Answer:

(0, -2)

Step-by-step explanation:

to find the y-intercept u need to put it into the slope intercept form.

first you move the X to the other side of the equation and get -5y = -2x + 10

then u divide -5 on each side and get y = 2/5 x -2

in y=mx+b and,b is the y intercept

so the y intercept is -2

Answer: B

Step-by-step explanation:

The simplified equation that is equivalent to the given equation is 16x - 5 = -47. The correct answer is option B.

The equation is given as follows:

15x - 5 + x = -47

A solution to an equation, as we know, is a variable value that, when substituted into the equation, provides a true claim.

To simplify the equation 15x - 5 + x = -47, we can combine the like terms on the left side of the equation.

Combining the terms with 'x', we have:

15x + x - 5 = -47

16x - 5 = -47

Therefore, the simplified equation that is equivalent to the given equation is 16x - 5 = -47.

Answer:

Your taking a close guess to what the answer or what something could be. This is why estimating is useful.

Step-by-step explanation:

Note: It the given equation the coefficient of [tex]x^2[/tex] must be -16 instead of 16.

Given:

Consider the height  of the water balloon over  time can be modeled by the  function

[tex]y=-16x^2+160x+50[/tex]

To find:

The maximum height of the water balloon  after it was thrown.

Solution:

We have,

[tex]y=-16x^2+160x+50[/tex]

Here, leading coefficient is negative. So, it is a downward parabola and vertex of a downward parabola, is the point of maxima.

If a parabola is [tex]f(x)=ax^2+bx+c[/tex], then

[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]

Here, [tex]a=-16,b=160,c=50[/tex]. So,

[tex]-\dfrac{b}{2a}=-\dfrac{160}{2(-16)}[/tex]

[tex]-\dfrac{b}{2a}=-\dfrac{160}{-32}[/tex]

[tex]-\dfrac{b}{2a}=5[/tex]

Now, put x=5 in the given equation.

[tex]y=-16(5)^2+160(5)+50[/tex]

[tex]y=-16(25)+800+50[/tex]

[tex]y=-400+850[/tex]

[tex]y=450[/tex]

The vertex of the given parabolic equation is (5,450).

Therefore, the maximum height of the balloon is 450 units after 5 units of time.
