Mathematics

suter [353]3 years ago

Answer:

-81 - y

Step-by-step explanation:

To simplify the expression -3[2-(y-5)]-4[3(y+1)-(6-y)(-2)] use order of operations or PEMDAS.

-3[2-(y-5)]-4[3(y+1)-(6-y)(-2)]

-3[2-y+5]-4[3y + 3+12 -2y]

-3[7-y] -12y-12-48+8y

-3[7-y] - 4y - 60

-21 + 3y - 4y - 60

-81 - y

If P(x) = x ^ 2 + x + 3 and Q(x) = 4x ^ 2 - 3 find P(8) .
lara [203]

Answer:

75

Step-by-step explanation:

Giving Q was not necessary because you aren't doing P(Q) or anything like that....

Anyways,

p(x) = x^2 + x +3\\

Since you're doing p(8), you would replace the x's with 8s.

(8)^2 + (8)  + 3 = 64 + 8 + 3 =75

So your final answer would be 75.

PLEASE HELP!!
artcher [175]

To solve for f, you need to isolate/get the variable by itself in the equation:

4(0.5f - 0.25) = 6 + f       Distribute 4 into (0.5f - 0.25)

(4)0.5f + (4)(-0.25) = 6 + f

2f - 1 = 6 + f        Subtract f on both sides to get "f" on one side of the equation

2f - f - 1 = 6 + f - f

f - 1 = 6       Add 1 on both sides to get "f" by itself

f - 1 + 1 = 6 + 1

f = 7

PROOF

4(0.5f - 0.25) = 6 + f      Substitute/plug in 7 into "f" since f = 7

4(0.5(7) - 0.25) = 6 + 7

4(3.5 - 0.25) = 13

4(3.25) = 13

13 = 13

Solve. -7x=x^2+12 help
Nat2105 [25]

Hey There!

The answer to your problem is x=-3 or x=-4 both answers are correct!

<u>Step 1: Subtract x²+12 from both sides.</u>

−7x−(x²+12)=x²+12−(x²+12)

−x²−7x−12=0

<u>Step 2: Factor left side of equation.</u>

(-x-3)(x+4)=0

<u>Step 3: Set factors equal to 0.</u>

-x-3=0 or x+4=0

<u>Get your answer:</u>

x=-3 or x=-4

Hey there!

In an isosceles triangle the 2 base angles are congruent, therefore angle B would measure 50 degrees just like the measure of angle A.

Thanks for using Brainly!

A random number generator is used to select a number from 1 to 100 what is the probability of selecting number 151
topjm [15]
0.

It is impossible for 151 to be selected, as it is outside the range of numbers (1 to 100) that can be selected. Therefore the probability is 0.
