Answer:x=30

Step-by-step explanation:

So first you have to find x so add all your sides together:

Equation: 45+2x+0.5x+x=150

Combine like terms: 45+3.5x=150

Subtract 45 from -45 -45

both sides: 3.5x=105

Then divide by 3.5: x=30

Now that you have your x substitute it in:

2(30)=60

0.5(30)=15

and the last one is x=30

And there you have all your sides! If you wanna check it just add up all the sides and it should equal 150.

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.

Step-by-step explanation:

Analyze the function’s graph to determine which statement is true.

Over the interval [–2.5, 0.5], the local maximum is 2.
As the x-values go to positive infinity, the function’s values go to negative infinity.
The function is decreasing over the interval (–1, 0.75).
The function is negative for the interval [–2, 0].

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 what is the difference between the number of adult cats at the Pet Care Center on Sunday and Monday

Answers

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.

Solution :

[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.

ck−kq+pq=dp

Step 3:

Add -ck to both sides.

−kq+pq=−ck+dp

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.

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.

O A y intercept: 2 slope: m = 4
В
intercept: -20; slopem
OC intercept: 5; slope: m = 4
D
intercept: 5: slope: m

Answers

Answer:

Slope is 1/4 (0.25) while y-intercept is 5

Step-by-step explanation:

Here, we are interested in getting the y intercept and slope of the line joining the given points.

We can get the slope by using any two points

Let’s say (4,6) and (12,8)

Mathematically; slope

= (y2-y1)/(x2-x1) = (8-6)/(12-4) = 2/8 = 1/4 = 0.25

To get the y-intercept, we proceed

kindly recall that the equation of a straight line is;

y = mx + c

where m is the slope and c is the y-intercept

Let’s take any of the points (28,12)

Thus:

12 = 0.25(28) + c

12 = 7 + c

c = 12-7

c = 5

Divide. Then, check with multiplication.
