-6x + 3 = 5
How do I solve this??????????????

Answers

Answer:

Step-by-step explanation:

you subtarct the 3 on both sides so it would be -6x=2

then you divide on both sides by -6 so it would look like x=-1/3

Answer:

x= -0.33 or -1/3

Step-by-step explanation:

What you have to do is isolate the x variable, you do the opposite to the other side of the equation to isolate the x.

Step 1- Subtract 3 to both sides of the equation.

-6x+3= 5

     -3  -3

-6x= 2

Step 2- Divide both sides of the equation by -6.

-6x= 2

 -6  -6

x= -0.3333...

So, x equals -0.333 or -1/3.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

6x - 3y = 24

x-intercept means y = 0.

So,

6x - 3 x 0 = 24

6x - 0 = 24

6x = 24

x = 4

Now,

The x-intercept means at 4 minutes the distance from home is o.

Consider the equation 1.2x + 4.8y = 18



If we graph the equation, what is the slope of the graph?

Answers

Answer:

-1/4

Step-by-step explanation:

For this equation, first divide both sides by 1.2, to get x+4y=15. Then, subtract x from both sides. Now, with 4y=-x+15, divide by 4. You should get y=-1/4x+15/4 (15/4=3 3/4 or 3.75). The formula y=kx=b, where k is slope, means the slope is -1/4.

Given :

The ratio of adult cats to kittens at a pet care center on Monday was 5:4 .

There were 36 kittens there that day Sunday 46 adult cats were at the Pet Care Center.

To Find :

The difference between the number of adult cats at the Pet Care Center on Sunday and Monday.

[tex]\dfrac{\text{Number of Adult cats }}{\text{Number of kitten}}=\dfrac{5}{4}\\\\\dfrac{n}{36}=\dfrac{5}{4}\\\\n=45[/tex]

So, number of adult cats on Monday are 45.

It is given that, number of adult on Sunday are 46.

Therefore, the difference is 46-45 = 1.

Hence, this is the required solution.

Eva, Josh, and David gather and shell pecans for their mother. Eva gathers 2 1/2 pounds of pecans, Josh collects 3.25 pounds, and David harvests 4 3/8 pounds. If they place all the pecans in one basket and each shells the same amount of pecans, how many pounds would each person shell? Group of answer choices

Answers

Answer:

3.375 pounds.

Step-by-step explanation:

Total number of pounds of pecans =

2 1/2 pounds of pecans + 4 3/8 pounds + 3.25 pounds

= (6.875 + 3.25) pounds

= 10.125 pounds.

The total number of person = 3 person.

Therefore, the number of pounds each person would shell =

10.125 pounds/3

= 3.375 pounds

Can someone pls explain the law of indices​

Answers

Answer:

Indices are used to show numbers that have been multiplied by themselves. They can also be used to represent roots, such as the square root, and some fractions. The laws of indices enable expressions involving powers to be manipulated more efficiently than writing them out in full.

Using indices

An index, or power, is the small floating number that appears after a number or letter. The plural of index is indices. Indices show how many times a number or letter has been multiplied by itself.

Given the quadratic function f(x) = (x + 6)(x – 3):
The x-intercepts are
The y-intercept is

Answers

Answer:

Step-by-step explanation:

Given quadratic function is,

f(x) = (x + 6)(x - 3)

For x-intercept,

Substitute the value f(x) = 0.

(x + 6)(x - 3 = 0

x = 3, -6

So the x-intercepts will be,

(-6, 0) and (3, 0)

For y-intercept,

Substitute the value for x = 0,

f(0) = (0 + 6)(0 - 3)

     = -18

Therefore, y-intercept of the given quadratic function will be (0, -18).

Minimum salary is 250$. Rate of commission is 5.65% . Weekly sales are 1,515. Whats the gross pay

Answers

Minimum salary: $250
Sales: 1515
Commission: 5.65% x 1515 = $85.5975

Gross Salary: 250 + 85.5975 = $335.5975

The gross pay would be $335.5975.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have been given that the minimum salary is $250

Here Weekly sales = 1515

Total commission = 5.65% × 1515

Total commission = 5.65/100 × 1515

Total commission = $85.5975

To determine the gross pay

We have to add the minimum salary and total commission,

Gross Salary = 250 + 85.5975

Gross Salary = $335.5975

Therefore, the gross pay would be $335.5975.
