2 : x
17 : 102
Cross multiply.
17x = 204
Solve for x; how many batches for 102 people.
17x=204
X = 12
She needs to make 12 batches
Answer:
31
Step-by-step explanation:
-4+16+19=31
The answer is <span>1) ± √x+81
</span>
Step 1: Substitute y for f(x). <span>
Step 2: </span>Since every (x, y) has its partner (y, x)y switch x and y.
Step 3: <span>Solve for y.
Step 1.
The function is: f(x) = x</span>² - 81
Substitute y for f(x): y = x² - 81
Step 2.
Switch x and y: x = y² - 81
Step 3.
Solve for y (which is now f⁻¹(x)): f⁻¹(x) = y
x = y² - 81
y² = x + 81
y = +-√(x+81)
Therefore, the choice 1) is correct.
Answer:
$552.90
Step-by-step explanation:
There are 52 weeks in a year
28,751/52= 552.9038462
since this is money you just round
We know that if two lines are Parallel then both the lines have same Slope.
Given : Equation of 1st Parallel line is -x + 3y = 6
this can be written as :
3y = x + 6
y = x/3 + 2
Comparing with standard form : y = mx + c
we can notice that slope = 1/3
We know that the form of line passing through point (x₀ , y₀) and having slope m is :
y - y₀ = m(x - x₀)
Here the 2nd Parallel line passes through the point (3 , 5)
x₀ = 3 and y₀ = 5 and we found m = 1/3
⇒ y - 5 = 1/3(x - 3)
⇒ 3y - 15 = x - 3
⇒ -x + 3y = 12
