Answer:

See explanation below for all parts

Step-by-step explanation:

Your current slope (m) is -1/2 (the orange colored slope) so the "opposite" slope would be 2/1 or 2(the blue colored slope)

The answer for number 3 is y=2x+b.

For number 4, plug in the point values for x and y and solve for b. The point given is (-4,-5).

-5=2(-4)+b Now simplify

-5=-8+b then add 8 to both sides to isolate b

3=b or b=3

For number 9, you now know that m is 2 and b is 3

y=2x+3

<h3>What are factors? </h3>

The factor of a number is a number that can be used to divide another number number evenly. For example, a factor of 20 is 2.

<h3>How many plants are in each row? </h3>

The number of plant in each row would be a factor of 15 that is between 4 and 8.

Factors of 15 = 1, 3, 5, 15.

Let the experiment be the toss of six coins in a row. Let X be number of of coins that turn up heads. Determine whether the foll

Leni [432]

Answer:

True

Step-by-step explanation:

When a coin is tossed six coins in a row, there are a total of $2^6$ outcomes.

The possible number of times for a heads are {0, 1, 2, 3, 4, 5, 6}.

Let our random variable, Number of coins that turn up heads be X

X={0, 1, 2, 3, 4, 5, 6}.

The event that X<3 and the event that X>3 cannot occur simultaneously in the same outcome.

In an outcome, its either one of the following happens:

Number of heads = Number of Tails =3
Number of heads < Number of Tails
Number of heads > Number of Tails
Number of heads cannot be greater than Number of Heads

Therefore, the events that X<3 and X>3 are independent.

Katherine uses $\frac{7}{10}$ of a gallon of red paint to paint $\frac{3}{5}$ of her wall. How many gallons of red paint will sh

scZoUnD [109]

Answer:

1.167 gallons

Step-by-step explanation:

Given that:

Fraction of red paint used = 7/10 of a gallon

Fraction of wall painted = 3/5

Gallon of paint required to paint the entire wall:

Fraction of entire wall = 1/1

7/10 paint = 3/5 wall

x paint = 1 wall

Cross multiply

(3/5)x = 7/10

Divide both sides by 3/5

3/5x ÷ 3/5 = 7/10 ÷ 3/5

(3/5)x * 5/3 = 7/10 * 5/3

x = 35 / 30

x = 7/6 = 1.167 gallons of red paint

325 Adult tickets were sold

• In Mathematics, algebra is a branch which deals with symbol and the rule for manipulation of those symbols. Algebra is divided into different sub branches such as advanced algebra, abstract algebra , linear algebra, elementary algebra etc.

• The basics of algebra contains numbers, variables, constants, expressions and equations. The basic operations in mathematics are addition, subtraction, multiplication, division.

Let the number of adult tickets be x

Then the number of student tickets will be x-72

Total tickets will be x+x+72

And the total tickets sold are 578

= x + x -72 = 578

2x – 72 = 578

=2x = 578+72

2x = 650

x = 325

Therefore, the total number of adult tickets sold are 325.
