2x + y = -4
y = -2x - 4
differentiate:
y' = -2
m=-2 perpendicular = -1/m = -1/-2 = 0.5, x=2 y=-8
y=mx+c
-8=0.5(2) + c
-8 = 1 + c
-9 = c
y = .5x - 9
OR you can use y-y_1 = m(x - x_1), where x_1 = 2, y_1 = -8, m = 0.5
y - -8 = 0.5(x - 2)
y + 8 = 0.5x - 1
y = 0.5x - 9
same answer either way
Answer:
log(x²-1)-(log5+logx)
Step-by-step explanation:
For this problem we need to make use of two existing logarithmic properties. These are:
- logM/N is equal to logM - logN
- logMN is equal to logM+logN
Following the first property, we can simplify the expression to:
log(x²-1)-log5x
Then, we will use the second property to the term 5x. The final form of the expression would then be:
log(x²-1)-(log5+logx)
Thus the answer is log(x²-1)-(log5+logx)....
Let's solve step by step
Step 1: First you need to know that quotient is the answer to a division problem.
Now that we know that we can just divide 26,234 by 42.
Step 1: Divide
You can Divide 26,234 by 42 using a calculator
once you typed in 26,234/42 than should equal <span>624.619047619
Step 3: Round (this step is optional)
To make the answer more clear we can round 624.619047619 to the hundreds place.
</span>
624.619047619 is rounded to <span>624.62
</span><span>
Therefore your answer is </span>624.619047619 or rounded to 624.62. (either answer will be correct)

A(b+c)=ab+ac
we have
9(72)=9*?+9*2
c=2
sub, but it must be equal to minus 2 from 72
7(70+2)=9*70+9*2
the question mark is 70
and the restult of the equation is 648
?=70
Answer:
$55.
Step-by-step explanation:
We have been given that a website-hosting service charges businesses a onetime setup fee of $350 plus d dollars for each month. A business owner paid $1,010 for the first 12 months, including the setup fee.
We can use our given information to form an equation as: 
Now let us solve for d.
Therefore, the value of d is $55.
