Elementary Algebra Skill

The answer is a = $\frac{4}{-3}$

Step-by-step explanation:

1. Convert the mixed fraction to an improper fraction

To find the numerator, multiply the denominator by the whole number and add the numerator to it.

The denominator remains the same.

So, 2 $\frac{2}{3}$ will be $\frac{8}{3}$

2. Now the equation is,

$\frac{3}{2}$ a - $\frac{4}{3}$ a = $\frac{10}{3}$ + $\frac{8}{3}$ a

3. Take LCM on both sides.

For the left side, multiply the first fraction by $\frac{3}{3}$ and multiply the second fraction by $\frac{2}{2}$

$\frac{3*3}{2*3}$ a - $\frac{4*3}{3*3}$ a = $\frac{10+8a}{3}$

4. Solve by making a the subject

$\frac{9a-8a}{6}$ = $\frac{10+8a}{3}$

$\frac{a}{6}$ = $\frac{10+8a}{3}$

$\frac{3a}{6}$ =10+8a

$\frac{a}{2}$ = 10 + 8a

a = 2(10 + 8a)

a = 20 + 16a

a-16a = 20

-15a = 20

a = $\frac{20}{-15}$

a = $\frac{4}{-3}$

Therefore, the answer is a = $\frac{4}{-3}$

Plot point for negative 4 and negativie 1

Allushta [10]

Answer:

Step-by-step explanation:

(-4, -1) is what you asked to be plotted.

The first number is what number you go to on the x axis (horizontal).

The second number is what number you go to on the y axis (vertical).

I've attached a picture to help demonstrate. :)

The way I remember which comes first is to keep it alphabetical. X comes first, so go on the x axis first, then y

We're given

$\displaystyle \int_4^{-10} g(x) \, dx = -3$

which immediately tells us that

$\displaystyle \int_{-10}^4 g(x) \, dx = 3$

In other words, swapping the limits of the integral negates its value.

Also,

$\displaystyle \int_4^6 g(x) \, dx = 5$

The integral we want to compute is

$\displaystyle \int_{-10}^6 g(x) \, dx$

which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is

$\displaystyle \int_{-10}^6 g(x) \, dx = \int_{-10}^4 g(x) \, dx + \int_4^6 g(x) \, dx = 3 + 5 = \boxed{8}$
