Put the values of d = 7 and f = -3 to the expression 2(10 - d) + f

Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

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

2(10 - 7) + (-3) = 2(3) - 3 = 6 - 3 = 3

What are the x- and y-intercepts of the function graphed below?*
My name is Ann [436]

Answer:

(3,0) and (0,6)

Step-by-step explanation:

(x,y) is the only way to make ordered pair.

The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).

Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.

So the answer is (3,0) and (0,6).

Find the area of a square with side length x when x is equal to the given value. Are the area of a square and the length of its
anyanavicka [17]

Step-by-step explanation:

The formula for calculating the area of a square is expressed as;

A = x² where;

x is the length of one side of the square

Given

x = 10in

A = 10²

A = 10 * 10

A = 100in²

Area of the square with side length 10in is 100in²

From the equation A = x², we can see that as the value of x increases, the value of the area also increases and vice versa. This means that the area of the square is directky proportional to its length. Hence we can say YES, the area of a square and the length of its side directly proportional

How is the process of rewriting literal equations similar to the process of solving equations in one variable?How is it differen
TEA [102]
A literal equation<span> is, simply put, an equation that has a lot of letters or variables.
example :
A = bh 
Lets solve it for b.
A = bh
A/h = bh / h
A/h = b

Now lets say we have equation in one variable like 10 = 5x
we can find x simply by,  x = 10 / 5 = 2

The way of solving it similar. The difference is literal equation have more variables, you solve for certain variable in terms of another variables while in one variable you get the direct number.
