Answer:
x=−3y−15
Step-by-step explanation:
Let's solve for x.
x+3y=−15
Step 1: Add -3y to both sides.
x+3y+−3y=−15+−3y
x=−3y−15
Answer:
x=−3y−15
Step-by-step explanation:
last week there were
62 + 60 + 2 = 124 customers.
that means that the fraction of the customers, who paid by credit card, was
2/124 = 1/62
in situations like that, when we use history data and try to predict future behavior, we use that past experience and extrapolate to a predicted result.
we simply say that we expect the same fraction, 1/62, if customers to use credit cards.
for the absolute number of predicted credit card customers we multiply the predicted number of customers by the expected fraction
1000 × 1/62 = 500/31 = 16.12903226... ≈ 16
so, he expects 16 credit card customers.
Answer:
Step-by-step explanation:
We have been given the equation:
And
Second equation can be rewritten as:
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
Now substitute in equation (1) we get:
Answer:
Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. There is no finite way to express them. ( examples: √2, π, e)

⇒ First, factor the numerator by grouping:
⇒ Now, factor the denominator by grouping:
⇒ We must determine which values of <em>e</em> and <em>f</em> are unacceptable, meaning, will make this expression undefined. These will be the values of <em>e</em> and <em>f</em> that make the denominator equal to 0.
- ⇒ To find these values, let's set each term in the denominator equal to 0, and solve for <em>e</em> and <em>f</em>.
- ⇒ ⇒
- ⇒
- ⇒ The restrictions for <em>e</em> and <em>f</em> include and .
⇒ Reduce values in the numerator and denominator:
