Y = -2x - 5

Mathematics
1 answer:
lions [1.4K]3 years ago
6 0

Answer:

A. One line

Step-by-step explanation:

Let rearrange the system of equations into explicit forms:

y = -2\cdot x - 5

6\cdot x + 3\cdot y = -15

3\cdot y = -6\cdot x - 15

y = -2\cdot x - 5

The second equation is identical to the first one, which means that there is just one line.

Find the surface area of the prism.
Maurinko [17]

Answer:

326m²

Step-by-step explanation:

Find the area of each side and find the total sum from each individual area:

2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326

So the surface area of the prism is 326m²

A variety pack of snacks contains 4 pretzel bags, 3 popcorn bags and 3 cheddar cracker bags. What is the probability that someon
Svetlanka [38]

Answer:

2/15

Step-by-step explanation:

Given that :

pretzel = 4

Popcorn = 3

Cheddar cracker = 3

Total = 4 + 3 + 3 = 10

Probability = Required outcome / Total possible outcomes

Selecting with replacement :

First selection :

P(pretzel bag) = 4 / 10

Second selection :

P(pretzel bag) = 3 / 9

P(2 pretzel bags) = 4/10 * 3/9 = 12 / 90 = 2/15

please help me i have a huge science test that i have to study for after this so PLEASE HELP ME GET THE ANSWER
enot [183]
Usually, quadratic equations equal 0, and to find the solution you need to make x equal the value that, when added or subtracted to the rest of its bracket, makes 0. This means that your answer is (x + 5)(x - 2) = 0, because 5 - 5 = 0 and 2 - 2 = 0. I hope this helps! Let me know if you would like me to explain further :)

A fraction is a way to describe a part of a whole. A fraction can be a proper fraction, an improper fraction, or a mixed fraction.

<h3>What is a Fraction?</h3>

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

A fraction consists of two whole numbers, a number that is above the fraction line which is the Dividend, while the number that is below the fraction line is known as the denominator and is the divisor. The result or the answer which we get when we solve the fraction is the factor or can be said, it is the quotient of the operation.

Suppose there is a fraction, a/b which is equal to c, then,

a is the dividend, b is the divisor, and c is the quotient.

49.5 is what percent of 33
Svet_ta [14]



  49.5 over 33 and X over 100 cross multiply so multiply 33 by x you get 33x then multiply 100 by 49.5 you get 4,950 then divide 4,950 by whatever is in front of X so 33 4,950 divided by 33 equals 150%
49.5/33   X/100   49.5x100= 4,950    33* x = 33x  4,950/33=150
