true or false? A subtraction expression with a positive integer and a negative can have a difference of zero

Answer:

40J

Step-by-step explanation:

YOU say 1/2 x 5 x4² ( 4 is velocity. 5 is mass )

it becomes 1/2 x5 x16

then it becomes 1/2 x 80

half of 80 is 40

the answer is then 40 JUOLES

Answer:

answer is D Add all the numbers that represent them x and do the same with the others then multiply by 4

Answer:

Basically you just add the like terms together. Like terms are terms that have the same power, like 1, or 2 to the second power. x has a power of zero.

Answer:

0

Step-by-step explanation:

1. The formula to find the slope of a line given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. All we have to do is plug in the values, and then we get our answer.

2. (Solving)

Therefore, the slope is 0.

Step-by-step explanation:

A quotient is a fraction.

A sum is addition.

A variable is an unknown number shown by using a letter.

Therefore, the answers for quotient and variable in this picture should be switched. However, the negative sign has to be included, so the quotient should be a -9/y.

and there is no x-intercept. y= 10

Area of parallelogram :

Height of a parallelogram is 6.4 feet

The question is wrong because as the given angle is 90, the hypotenuse(11cm) should be greater than 16cm

Answer:

cant solve

Step-by-step explanation:

(sorry im not good at english) because there is no right triagle in which the length of the side of the right angle is greater than the length of the hypotenuse.

-2/5 or -0.4

Answer:

Answer is

Step-by-step explanation:

9-3+18

9-21

-12

Answer:

24

Step-by-step explanation:

Follow the order of operations and do the multiplication first

2*9=18

Then go from left to right as it is all addition and subtraction from there

9-3+18

9-3=6

6+18=24

Answer:

116 miles (186 km)

Step-by-step explanation:

a diameter is always twice the radius.

the only pairs in this list, where one number is twice the other, is :

2.5 and 5

7.6 and 15.2

so,

2.5 is the radius of A

5 is the diameter of A

7.6 is the radius of B

15.2 is the diameter of B

15.7 is then the circumference of A (as the smaller of the remaining 2 numbers).

47.7 is the circumference of B.

this is also proven by the formula for the circumference of a circle : c = 2×pi×r

A joint family is a form of family where the grand-parents, father, mother, and children live unitedly under one roof.

Answer:

The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0

has solutions x = 2 and x = 3.

Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.

Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.

A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.

As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

Answer:

280 student tickets

520 adult tickets

Explanation:

I'm guessing this is the question you meant to ask:

Eight hundred tickets were sold for a movie production and the receipts for the performance wear $8600. The tickets for adults and students sold for $12.50 and $7.50, respectively. How many of each ticket were sold?

Answer:

45mph

Step-by-step explanation:

To find the average speed, we must add together all of the different speeds and divide by the quantity of them (assuming all of them are equal in time). In this case we have 2: 50 and 40.

[tex]50+40=90[/tex].

Then we divide by 2, since there were two segments of equal length

[tex]\frac{90}{2} =45[/tex]

45mph

Answer:

-3(9y^2-12y^3+4y^4+x^2 - 4xy+3y^2)

Step-by-step explanation:

Answer:

x = $1.25; y = $6.50

Step-by-step explanation:

Let x be the cost of movies and y be cost of video games.

Month 1 has 2x+3y = 22

So here x = (22-3y)/2 and y = (22-2x)/3

Month 2 has 4x+8y =57

Here x = (57-8y)/4 and y = (57-4x)/8

Now you have two options: Find the y or the x. I will demo the x and you can try the y if you wish.

(22-2x)/3 = (57-4x)/8

176-16x = 171-12x

-4x = -5

x = 1.25

Now with the x found, you plug it into either of the y equations to figure out the other variable.

y = (22-2(1.25))/3

y = 6.5

And to double check:

y = (57-4(1.25))/8

y = 6.5

Answer:

C I'm pretty sure yeah it's c

Answer:

the answer to your question is 5+6+7+8

Answer:

ok

Step-by-step explanation:

The four consecutive numbers are 5, 6, 7, 8

The smallest number is 5.

Thus their sums equal to 26.
