Answer: D

Step-by-step explanation:

this is in y=Mx+ b form. M stands for the slope and b stands for the y intercept, or where the line intersects with the y-axis.

Going left to right, the line slopes downwards, therefore it is a negative Slope. This narrows down your answer to either a or d. the slope is -1 because you can only ever write x by itself if it means 1x. In this case it is negative so it would look like this: -x

for the y-intercept, simply look at where the line passes through the y-axis. In this case, it is positive 2.

your finished equation would be: y=-x+2

i hope this is helpful

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(

salantis [7]

Answer:

There are no simple factors to this expression. You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:

$y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}$

Solve for X <br><br> Please and thanks

Tpy6a [65]

<u>Given</u>:

The measure of ∠ABD is (4x + 15)°

The measure of ∠DBC is (13x + 7)°

We need to determine the value of x.

<u>Value of x:</u>

Since, we know the property that every angle in a rectangle is 90°

Hence, the value of x can be determined by adding the two angles and equating to 90°

Thus, we have;

$\angle ABD+\angle DBC=90^{\circ}$

Substituting the values, we have;

$4x+15+13x+7=90$

$17x+22=90$

$17x=68$

$x=4$

Thus, the value of x is 4.

Suppose you buy a CD for $300 that earns 3% APR and is compounded quarterly. The CD matures in 5 years. Assume that if funds are

klio [65]

Value of the CD after 3 months is given by 300(1 + 0.03 / 4) = 300(1 + 0.0075) = 300 x 1.0075 = $302.25.
Therefore, interest for 3 months = $302.25 - $300 = $2.25
