Answer:

Line graph and Bar graph

Step-by-step explanation:

Since Line Graph is used to visualize the data that change over time, So Line Graph can use for representation.

Also, since it is a categorical data, so Bar graph is also the best representation for showing how the population of a country changes each month.

Thus, Option A and D is correct.

Further, Line Graph is used to visualize the data that is change over time. Here each information is connected with others.

Scatter Plot is used to visualize the two-dimension graph that uses the point to show the values obtained by both the variables.

Circle graph also known as pie chart used to visualize the data proportionally. Here the arc of the circle is used to represent only the proportion of all the data.

Bar graphs are made up of columns with different labels of categorical data of different heights shows the size of the group of different labels.

Please help. 50 points + brainliest

Korvikt [17]

Answer:

1. (a-c) $\sqrt{x}$ + b $\sqrt{y}$

2. 9m + 2 $\sqrt{n}$

3. 6a

4. (5a - 3b) $\sqrt{5y}$

Step-by-step explanation:

1. since a and c share the same squareroot x, you can combine these together.

2. First add like terms together. 4m - m + 6m = 9m. Then 5 $\sqrt{n}$ and -3 $\sqrt{n}$ combined equals 2 $\sqrt{n}$

3. First simplify the square roots. squareroot of 16 is 4. square root of 49 is 7. square root of 81 is 9. They are all multiplied by a in the expression. Thus 4a - 7a + 9a = 6a

4. First simplify the radicals, they are not perfect. square root of 125 is equivalent to sqrt(25 * 5), which sqrt of 25 is 5, but we keep the sqrt of 5. For sqrt of 45, it is the same as sqrt9 * sqrt5. sqrt of 9 is the same as 3 and we keep sqrt 5. Thus we get the below:

5a $\sqrt{5y}$ - 3b $\sqrt{5y}$

We can combine the two like terms and get the final answer above.

Which shows one way to determine the factors of x3 + 5x2 – 6x – 30 by grouping?

frutty [35]

Answer:

Step-by-step explanation:

group them first :

( x3+5x2) and ( -6x-30)

then simply by gcf ( greatest common factor) :

x2(x+5) and -6(x+5)

and just add them together:

x2(x+5)-6(x+5)

bonus :

it can be written as (x2-6)(x+5)

Determain the equation, in slope intercept form, of the line of the line that has a slope of -6 and passes through the point P(-

Vinil7 [7]

Answer:

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

m = -6

(-3, 2) ⇒ x₀ = -3, y₀ = 2

The point-slope form of the equation:

y - 2 = -6(x + 3)

So:

y - 2 = -6x - 18 {add 2 to both sides}

y = -6x - 16 ← the slope-intercept form of the equation
