{\qquad\qquad\huge\underline{{\sf Answer}}}

The two lines shown in the figure intersects each other ~

Therefore,

  • 3x - 10 = 2x + 30

[ by vertical opposite angle property ]

Now let's solve for x :

\qquad \sf  \dashrightarrow \:3x - 10 = 2x + 30

\qquad \sf  \dashrightarrow \: 3x - 2x = 30 + 10

\qquad \sf  \dashrightarrow \:x = 40

Sara has $150 in her savings account. The amount in her account increases by %6 every year. If she does not put more money into
strojnjashka [21]

Answer:

$159

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

y=a(1+r)^x

where

y is the balance in the saving account

x is the number of years

a is the initial amount

r is the percent rate of change

we have

a=\$150\\r=6\%=6/100=0.06

substitute

y=150(1+0.06)^x

y=150(1.06)^x

For x= 1 year

substitute

y=150(1.06)^1=\$159

Combining the like-terms, the result of the addition of polynomials f(x) and g(x) is given by:

f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}

<h3>How do we add polynomials?</h3>

We add polynomials combining the like-terms, that is, adding terms with the same exponent.

In this problem, the polynomials are:

  • f(x) = 3x^{\frac{1}{2}} + 7x^{-\frac{1}{4}} + 8x^{-4}
  • g(x) = -\frac{7}{4}x^{\frac{1}{2}} + 12x^{-\frac{1}{4}} - 21x^3

Combining the like terms, the addition is given by:

f(x) + g(x) = \left(3 - \frac{7}{4}\right)x^{\frac{1}{2}} + (7 + 12)x^{-\frac{1}{4}} + 8x^{-4} + 21x^3

f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}

.Solve the system of equations. Use elimination
Elina [12.6K]

Answer:

a) (-9,3)

Step-by-step explanation:

   x + 2y = -3

- (x -    y = -12)

<u />

x + 2y = -3

<u>- x + y =  12</u>

       3y =  9

          y = 3

x - y = -12

x- 3 = -12

x= - 9

(-9, 3)
