Answer:

"Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.

Answer:

16.67%

Step-by-step explanation:

If area triples every year :

This means that :

With an initial area of 10;

Area at the end of the year = 3 * 10 = 30

Percentage increase per year :

(30 - 10) / 10 * 100%

(20 / 10) * 100%

2 * 100%

= 200% per year

Therefore, monthly increase %

Yearly % increase ÷ number of months in a year

200% ÷ 12

= 16.666666%

= 16.67%

Answer:

y = 1x + 7

Step-by-step explanation:

The equation formula for this scenario is y = mx + b

m = slope

b = y-intercept

To find the slope, pick two points. I picked (2,9) and (4,11).

Subtract 11 from 9, you'll get 2.

Subtract 4 from 2, you'll get 2.

2/2 equals 1.     The slope (m) = 1

To find the b, y-intercept, plot the points on a graph and see if the linear line across the y-intercept.  For this case, the y-intercept is 7.

The equation is:  y = 1x + 7

Answer:

x=35

Step-by-step explanation:

7x+55≥300

    -55 -55

--------------------

7x≥245

now divide both sides by 7

x=35

Answer:

Step-by-step explanation:

There is 1/2 cake left, or .5, or 50%.

.5 divided by 4 equals .125, or 1/8, of 12.5%

In fraction form, each person will receive 1/8 slice of cake.

Answer:

Step-by-step explanation:

(-3 + 1)/(2 + 2)= -2/4= -1/2 is the slope

Answer = C

because all are not in set pairs only no. C is pair of set

Answer:

For quadratic equations that cannot be solved by factorising, we use a method which can solve ALL quadratic equations called completing the square. We use this later when studying circles in plane analytic geometry.

Completing the square comes from considering the special formulas that we met in Square of a sum and square of a difference earlier:

(x + y)2 = x2 + 2xy + y2 (Square of a sum)

(x − y)2 = x2 − 2xy + y2 (Square of a difference)

To find the roots of a quadratic equation in the form:

\displaystyle{a}{x}^{2}+{b}{x}+{c}={0}ax

2

+bx+c=0,

follow these steps:

(i) If a does not equal \displaystyle{1}1, divide each side by a (so that the coefficient of the x2 is \displaystyle{1}1).

(ii) Rewrite the equation with the constant term on the right side.

(iii) Complete the square by adding the square of one-half of the coefficient of x to both sides.

(iv) Write the left side as a square and simplify the right side.

(v) Equate and solve.

Example 1

Find the roots of x2 + 10x − 4 = 0 using completing the square method.

Answer

Example 2

Solve 4x2 + x = 3 by completing the square.

Step-by-step explanation:

Answer:

To determine the value of X, what you would need to do is to use a trigonometric ratio, that would make use of the value of x and the side length of 12. This can either be, sin 30 or cos 60. Both of them will enable you to solve for x.

The final value for x would be either

X = 12/Sin 30

X = 12/Cos 60

Compute these in your calculator and you will find the final value in these cases.

Answer:

Step-by-step explanation:

remove the parenthesis

5x+10=20

5x+10-10=20-10

5x=10

x=2

This is because the x coordinates of each point are the same (both are 3). These two points form a vertical line, and any vertical line has an undefined slope.

We could use the slope formula to see that...

m = (y2-y1)/(x2-x1)

m = (1-2)/(3-3)

m = -1/0

m = undefined

We cannot divide by zero, so that's why the slope is undefined.

Answer:

-3

Step-by-step explanation:

-9 divided by +3 can be written as -9 divided by 3, because when you have a positive number, you don't have to write a plus sign in front of it. Next, we can just do 9/3 and then add the negative sign to the result to get our answer. 9 divided by 3 is equal to 3, and when you add the negative sign, you get -3.

y = x / -4
