Answer:

This is a question about accepted idiomatic usage and level of formality rather than a question of grammar. These forms are not technically “grammatically incorrect,” but neither are accepted idiomatic usage. If you want to be fluent in your usage, and you are willing to come off as formal and a bit peremptory and demanding, you would say, “I would appreciate it if you …” But unless you want to convey impatient formality, you would probably want to say instead, “I would be grateful if you …”

You would probably never in any circumstance say "I will appreciate if you.." or "I would appreciate if you.."

Step-by-step explanation:

And you would also probably never even say "I will appreciate it if you.." This is just not the way English speakers speak. One reason you wouldn’t say “I will appreciate it” (besides the fact that it would sound impatient) is that you need to use the subjunctive “would” when you are using “if,” instead of the predictive “will.” You are only predicting that if a hypothetical event occurs, appreciation will occur. For instance: You impatiently say, “I would appreciate it if you would pay your rent.” You are predicting (or sarcastically claiming to predict) that if the rent is paid, you will be appreciative.

Help assap with this question?!?!?
Irina18 [472]
Slope-intercept form is y=mx+b
m is slope and b is y-intercept.
So, if you have -5x-3y=3
Make it into y=something
So, -3y=3+5x
y= -3/3 + 5/-3 x
y= -1 - 5/3 x
Same as the first one in your pic.

Find the value of L in the equation. <br> s=(n÷2)(a+L)
Anon25 [30]

Answer:

2s/n-a=L

Step-by-step explanation:

So first we divide (n÷2) so it will be s/(n÷2) =a+L. Next we subtract L and get s/(n÷2)-a. That's not it yet, since 2 is being divided in the denominator, we have to reciprocal it meaning multiply, it to the top value. So it would 2s/n-a=L. But you can just leave it like that if you desire and your teacher doesn't mind.

If the distance from A (5,6) to B (1, b) is twice the distance from B to
Nimfa-mama [501]

Answer:

The possible values of b are -2.944 and -9.055, respectively.

Step-by-step explanation:

From statement we know that AB = 2\cdot BC. By Analytical Geometry, we use the equation of a line segment, which is an application of the Pythagorean Theorem:

AB = 2\cdot BC

\sqrt{(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2}} = 2\cdot \sqrt{(x_{C}-x_{B})^{2}+(y_{C}-y_{B})^{2}} (1)

Where:

x_{A}, x_{B}, x_{C} - x-Coordinates of points A, B and C.

y_{A}, y_{B}, y_{C} - y-Coordinates of points A, B and C.

(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2} = 4\cdot (x_{C}-x_{B})^{2}+4\cdot (y_{C}-y_{B})^{2}

Then, we expand and simplify the expression above:

x_{B}^{2}-2\cdot x_{A}\cdot x_{B} +x_{A}^{2} +y_{B}^{2}-2\cdot y_{A}\cdot y_{B} + y_{A}^{2} = 4\cdot (x_{C}^{2}-2\cdot x_{C}\cdot x_{B}+x_{B}^{2})+4\cdot (y_{C}^{2}-2\cdot y_{C}\cdot y_{B}+y_{B}^{2})

x_{B}^{2}-2\cdot x_{A}\cdot x_{B} + x_{A}^{2} +y_{B}^{2}-2\cdot y_{A}\cdot y_{B} + y_{A}^{2} = 4\cdot x_{A}^{2}-8\cdot x_{C}\cdot x_{B}+4\cdot x_{B}^{2}+4\cdot y_{C}^{2}-8\cdot y_{C}\cdot y_{B}+4\cdot y_{B}^{2}

If we know that x_{A} = 5, y_{A} = 6, x_{B} = 1, y_{B} = b, x_{C} = 1 and y_{C} = -3, then we have the following expression:

1 -10 +25 +b^{2} -12\cdot b+36  = 100 -8 +4 +36+24\cdot b +4\cdot b^{2}

b^{2}-12\cdot b +52 = 4\cdot b^{2}+24\cdot b +132

3\cdot b^{2}+36\cdot b +80 = 0

This is a second order polynomial, which means the existence of two possible real solutions. By Quadratic Formula, we have the following y-coordinates for point B:

b_{1} \approx -2.944, b_{2} \approx -9.055

In consequence, the possible values of b are -2.944 and -9.055, respectively.
