Which set of ordered pairs represents a function?

Zigmanuir [339]

A function will not have any repeating x values....all the x values must be different....now it can have repeating y values, just not the x ones.

so ur function is { (3,-1),(7,1),(-6,-1),(9,1),(2,-1)}.....because all the x values are different

Aidan has $7565 in his checking account. He invests it in an account that earns 3.5% interest compounded continuously. What is t

Fudgin [204]

Total amount = Pe^(rt)
where
P=principal
e=2.7182818284...
r=0.035
t=3 (years)

Total amount
= 7565(e^(0.035*3)
=$ 8402.53

Solve: (-5/6) × (9/20) + (-5/6) × 7/25 = ?

jonny [76]

$\bf \underline{★ How \:to\: do -} \\$

Here, we are given with four fractions to multiply two of them and to add two of them. If we add them directly by taking the LCM and adding them is not a similar way. We can clearly observe that in those four fractions, we have two fractions as common i.e, we have two fractions as same. If we have two fractions or numbers as same, we can solve the sum by an other concept called as distributive property. In this property, we multiply the common fraction with the sum of other two fractions. This concept can also be done with fractions as well as integers. So, let's solve!!

$\:$

$\bf \underline{➤ Solution-} \\$

${\tt \leadsto \dfrac{(-5)}{6} \times \dfrac{9}{20} + \dfrac{(-5)}{6} + \dfrac{7}{25}}$

Group the non-common fractions in bracket.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{9}{20} + \dfrac{7}{25} \bigg)}$

First we should solve the numbers in bracket.

LCM of 20 and 25 is 100.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{9 \times 5}{20 \times 5} + \dfrac{7 \times 4}{25 \times 4} \bigg)}$

Multiply the numerators and denominators in the bracket.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{45}{100} + \dfrac{28}{100} \bigg)}$

Now, write both numerators in bracket with a common denominator.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{45 + 28}{100} \bigg)}$

Now, add the numerators in bracket.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{73}{100} \bigg)}$

Write the numerator and denominator in lowest form by cancellation method.

${\tt \leadsto \dfrac{\cancel{(-5)} \times 73}{6 \times \cancel{100}} = \dfrac{(-1) \times 73}{6 \times 20}}$

Now, multiply the numerators and denominators.

${\tt \leadsto \dfrac{(-73)}{120}}$

$\:$

${\red{\underline{\boxed{\bf So, \: the \: answer \: obtained \: is \: \: \dfrac{(-73)}{120}}}}}$

What is .40 = .25 X

leva [86]

Answer:

x=1.6

Step-by-step explanation:

.40=.25x

you move .25 to the other side which would look like this .40/.25=x and then you solve for x, which you would get 1.6.

I need help with this math problem please

goblinko [34]

<em>Answer,</em>

<em><u>4a^3 − 10a + 6/3a^2</u></em>

<em>Explanation,</em>

<em><u>Just Simplify</u></em>

<em>= 16a^4 − 40a^2 + 24a/12a^3</em>

<em>= 16a^3 − 40a + 24/12a^2</em>

<em>= </em><em>4a^3 − 10a + 6/3a^2</em>

<u><em>Hope This Helps :-)</em></u>
