Solve using substitution.
y = 9
5x – 3y = -12

Answers

Answer 1

Answer:

5x-3(9)=-12

5x-27=-12

+27. +27

5x = 15

÷5. ÷5

x= 3

Answer 2

Answer:

Let's solve for x.

y=95x−3y

Step 1: Flip the equation.

95x−3y=y

Step 2: Add 3y to both sides.

95x−3y+3y=y+3y

95x=4y

Step 3: Divide both sides by 95.

95x

95

=

Answers

Answer:

[tex]g(2w)=6w+8[/tex]

Step-by-step explanation:

We know that [tex]g(z)=3z+8[/tex]

And we want to find [tex]g(2w)[/tex]

So, we will simply substitute 2w for z. This yields:

[tex]g(2w)=3(2w)+8[/tex]

Isaac conducted a scientific experiment. For a certain time, the temperature of a compound rose 3 3/4 degrees every 3/4 of an hour. What was the rate, in degrees per hour, that the temperature of the compound rose?

Answers

Answer: it should be 5

Step-by-step explanation: if 3 3/4 divided into three parts its 1 1/4. If we add 3 3/4 and 1 1/4, then we have 5

The rate of rise in temperature in degrees per hour will be equal to per hour.

What is an arithmetic operation?

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.

Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given information in the question,

The temperature rise of the compound to 3 3/4° every 3/4 of an hour.

1 hour = 60 minutes then,

3/4 of an hour = 3/4 × 60 = 45 minutes.

(15/4)° rise in 45 minutes or,

3.75° rise in 45 minutes.

Let the rise in temperature in 1 hour will be then,

x = (3.75 × 60)/45

x = 5° per hour.

Using reflection concepts, it is found that the correct option is:

a reflection of the point across the y-axis
