Answer:

the vertices of point R could be (-2,5) or (-2,9)

each point is 7 units away from Q since there are 7 units between P and Q

What would you get for 12y=2 1/4 the answer

myrzilka [38]

$y=\frac{3}{16}$

Solution:

Given expression:

$12y=2\frac{1}{4}$

To solve this and find the value of y.

Let us first convert the mixed fraction into improper fraction.

$$2\frac{1}{4} =\frac{(2\times4)+1}{4}$

$$ =\frac{8+1}{4}$

$$2\frac{1}{4} =\frac{9}{4}$

Now, substitute this in the given expression.

$12y=\frac{9}{4}$

Divide by 12 on both sides of the expression.

$\frac{12}{12}y=\frac{9}{4\times 12}$

$y=\frac{9}{48}$

To reduce this expression, divide by 3 on both numerator and denominator.

$y=\frac{9\div 3}{48\div 3}$

$y=\frac{3}{16}$

Hence the answer is $y=\frac{3}{16}$ .

What is the equation of the line that passes through the point (8,-3) and has an undefined slope?

BARSIC [14]

Answer:

x = 8

Step-by-step explanation:

A line with "undefined" slope is a vertical line, whose equation is of the form ...

x = constant

In order for the line to go through a point with an x-coordinate of 8, the constant must be 8.

x = 8 . . . . . a vertical line through (8, -3)

Which algebraic expression represents the phrase below? five times the sum of a number and eleven, divided by three times the su

anyanavicka [17]

<u>The overall </u><u>algebraic expression</u><u> will be: </u> $\frac{5(x+11)}{3(x+8)}$ <u />

Definition of algebraic expression -

An expression obtained by a finite number of the fundamental operations of algebra upon symbols representing numbers.

Five times the sum of a number and eleven, divided by three times the sum of the number and eight.

Let the number be x.

Five times the sum of a number and eleven means 5 multiplied to the sum of x and 11. In expression this will be written as:

5(x + 11)

Three times the sum of the number and eight means 3 multiplied to the sum of x and 8. In expression this will be written as:

3(x + 8)

So, the overall <u>algebraic</u> expression will be: $\frac{5(x+11)}{3(x+8)}$

y = 25x + 263 this equation represents how much money she will have, including her saving.

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

We have,

The saved amount of $263 by Jenna,

and also she earns $25 per day

if x represents the number of days she works,

and let's take y as the total amount she will have.

Then the equation becomes:
y = 25x + 263

Hence, y = 25x + 263 this equation represents how much money she will have, including her saving.
