Consider the standard form equation 2x-Ry=30. What value of R causes the graph to have a y-intercept of 5?

DochEvi [55]

Answer:

R = 6

Step-by-step explanation:

Given the equation of the line is 2x - Ry = 30

We know that the equation of a line with a as x-intercept and b as y-intercept is $\frac{x}{a} +\frac{y}{b} =1$

Now convert the above given line to the standard form

Divide the line by 30 we get

$\frac{2x}{30}-\frac{Ry}{30} =\frac{30}{30}$

$\frac{x}{15} -\frac{y}{\frac{30}{R} } =1$

Here the y-intercept is 30/R

Given y-intercept = 5

$\frac{30}{R} =5$

R = 6

Don’t understand this @ all

Pair (3,11) should be removed because the domain x should never be repeated in a function.
Plz mark me as brainliest? Hope it helps.

Find the value of c that makes each trinomial a perfect square. Then write the trinomial as a perfect square.

musickatia [10]

Answer:

d. c = 100; (x – 10)²

Step-by-step explanation:

Note that (x+a)²=x²+2ax+a².

In our case, 2a=-20, so 'a' must be -10.

Since c=a², and a=-10, c=(-10²)=100.

Since a=-10, the perfect square is (x – 10)²

Evaluate 7+5^2*4 Algebra 1

vagabundo [1.1K]

Hi there!

Answer:

=107

*The answer must have a positive sign.*

Step-by-step explanation:

<h2>Lesson: Order of operations</h2>

Parenthesis

Exponents

Multiply

Divide

Add

Subtract

It can also go left to right.

First, you do exponents.

$5^2=5*5=25$

$7+25*4$

Then, you multiply from left to right.

$25*4=100$

Finally, you add from left to right.

$100+7=107$

I hope this helps you!

Have a nice day! :)
