Graph the equation. There are multiple ways to do this.

You can create a table of values, use the quadratic formula, convert from standard to vertex form.

If you're trying to factor, you'll eventually notice this thing cannot be factored (no roots!). If you use the quadratic formula, you will get an imaginary answer (no roots!)

If you go in the route of picking points and coming up with a table of values you'll get a graph like this (see attachment) Notice there are no roots! because the graph never ever hits the x-axis

Devin is buying 2 concert tickets. The concert tickets have a regular price of $40 each. Devin has a coupon that gives a 5% disc

Svetach [21]

Given :

Devin is buying 2 concert tickets. The concert tickets have a regular price of $40 each.

Devin has a coupon that gives a 5% discount off of the regular price of the tickets. He will then pay a 10% purchasing fee on the discounted price of the tickets.

To Find :

Devin's total cost of the two tickets after the discount and the fee.

Solution :

Discount on price, D = 40×0.05 = $2 .

Price of product after discount, P = $( 40 - 2 ) = $38 .

Now, total price after adding purchasing fee is :

T = P + (P×0.10)

T = 38 + (38×0.10)

T = 38 + 3.8

T = $41.8

Therefore, Devin's total cost of the two tickets after the discount and the fee is $41.8 .

Hence, this is the required solution.

MrRa [10]

Answer:

Step-by-step explanation:

To find 25 percent, we must first divide by four.

515 divided by 4 is 128.75

Now we mark off 128.75 USD

Basically, subtract 515 by 128.75

We're left with 386.25

Answer:

Step-by-step explanation:

the Pythagorean theorem is

c is the hypotenuse which is the side opposite of the right angle

plug the numbers into the Pythagorean theorem

$x^2+(\sqrt{26})^2=13^2$

when squaring a square root, just take the number in the radical and get rid of the radical

$x^2+26=169$

subtract 26 from both sides

$x^2=$ $143$

find the square root of 143

143 is prime so it can just be written as

$x=\sqrt{143}$
