Answer:

The solution to the system of equations is:

[tex]x = -9[/tex],   [tex]y=-3.4[/tex]

Step-by-step explanation:

Given the system of equations

-2.1x + 4y = 5.3

2.1x - 5.5y = -0.2

Solving the system of equations using the linear combination method

[tex]\begin{bmatrix}-2.1x+4y=5.3\\ 2.1x-5.5y=-0.2\end{bmatrix}[/tex]

adding the equations

[tex]2.1x-5.5y=-0.2[/tex]

[tex]+[/tex]

[tex]\underline{-2.1x+4y=5.3}[/tex]

[tex]-1.5y=5.1[/tex]

solving -1.5y = 5.1 for y

[tex]-1.5y=5.1[/tex]

Divide both sides by -1.5

[tex]\frac{-1.5y}{-1.5}=\frac{5.1}{-1.5}[/tex]

[tex]y=-3.4[/tex]

substitute y = -3.4 in 2.1x - 5.5y = -0.2

2.1x - 5.5y = -0.2

2.1x - 5.5(-3.4) = -0.2

2.1x + 18.7 = -0.2

2.1x = -0.2-18.7

2.1x = -18.9

Divide both sides by 2.1

[tex]\:\frac{2.1x}{2.1x}\:\:=\:\:\frac{-18.9}{2.1}[/tex]

[tex]x = -9[/tex]

Therefore, the solution to the system of equations is:

[tex]x = -9[/tex],   [tex]y=-3.4[/tex]

Answer:

The nth term of the geometric sequence 7, 14, 28, ... is:

[tex]a_n=7\cdot \:2^{n-1}[/tex]

Step-by-step explanation:

Given the geometric sequence

7, 14, 28, ...

We know that a geometric sequence has a constant ratio 'r' and is defined by

[tex]a_n=a_1\cdot r^{n-1}[/tex]

where a₁ is the first term and r is the common ratio

Computing the ratios of all the adjacent terms

[tex]\frac{14}{7}=2,\:\quad \frac{28}{14}=2[/tex]

The ratio of all the adjacent terms is the same and equal to

[tex]r=2[/tex]

now substituting r = 2 and a₁ = 7 in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=7\cdot \:2^{n-1}[/tex]

Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:

[tex]a_n=7\cdot \:2^{n-1}[/tex]

Yes

Answer

C is WRONG

Step-by-step explanation:

The correct answer is A

The fog(1) is -41.

Let ƒ(x) = 5x2 – x + 1 and g(x) = –3x.

Evaluate the composition (ƒ ∘ g)(1).

= f(g(x) where x = 1

= f(-3x)

= -5(-3x)² - (-3x)+ 1

=-5(9x²)+3x+1

fog(x) = -45x²+3x+1

fog(1) = -45+3+1

= -41

Hence, The fog(1) is -41.

Answer:

35% of 60 = 21

the answer is 21

this is how you set it up

x/60=35/100

you first multiply 35 and 60 and your answer should be 2100 then you divide 2100 by 100 and that equals 21

Answer:

We can write 7 + 2 + 1 in two different ways.

a)

b)

Step-by-step explanation:

The commutative property of addition states that we can add the numbers in any order and get the same answer.

For example, if we add 'a' and 'b' together, the commutative property of addition states that we would get the same answer whether we add a + b or b+a.

In other words,

a + b = b + 1

In our case, we are given

7 + 2 + 1

According to the commutative property of addition, we can add the number in any order and get the same answer.

Therefore, we can write 7 + 2 + 1 in two different ways.

a)

b)

Verification:

Thus, the answer will remain the same in any order.

i.e.

7 + 2 + 1 = 7 + 1 + 2 = 1 + 7 + 2

Answer:

x = 2, y= -1 Or (2, -1)

Step-by-step explanation:

Let’s solve the system using substitution. First we can set the equations equal to each other:

x-3= -2x +3

Now solve for x

3x-3= 3

3x = 6

x=2

Now that we have x, we can plug it back into one of the original equations to get y

y= x-3

y= 2-3

y = -1

Finally, the solution to the system of equations is (2, -1).

Answer:

(2,-1)

Step-by-step explanation:

1.) y = x - 3

    y = -2x + 3

2.) Multiply top equation by 2

    2y = 2x - 6

    y = -2x + 3

3.) Add equations

    3y = -3

4.) Divide 3 from each side

     y = -1

5.) Substitute -1 for y in second equation

    -1 = -2x + 3

6.) Solve

     -4 = -2x

     x = 2

Therefore, (2, -1)

Answer:

1539

Step-by-step explanation:

We solve the above question using the Exponential decay formula

= A(t) = Ao(1 - r) ^t

Ao = Initial Amount invested = 7600

r = Decay rate = 55% = 0.54

t = time in weeks = 2

Hence:

A(t) = 7600(1 - 0.55)²

A(t) = 7600 × (0.45)²

A(t) = 1539

Therefore, the value of the quantity after 2 weeks is 1539

Answer: C

Step-by-step explanation:

Another point on the line y = 9/5(x) + 2  is (0, 2).

The correct option is B.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given:

The slope of the line is 9/5 and passes through the point (-10, -16).

So, the equation of the line is,

y + 16 = 9/5(x + 10)

y + 16 = 9x/5 + 18

y = 9/5(x) + 2

From the given choices,

Substituting x = 0,

we get,

y = 2

another point on the line is (0, 2).

Therefore, another point on the line is (0, 2).

Answer: the one on the top right

Step-by-step explanation:

Answer:

2 1/4 hours

Step-by-step explanation:

Okay, so- The first thing I did was see how much they got done per hour. Like this:

Sally  ⇒

3 hours = 1 room

1 hour = 1/3 of the room

Steve ⇒

9 hours = 1 room

1 hour = 1/9 of the room

Sally + Steve ⇒  

1 hour = 1/3 + 1/9 = 3/9 + 1/9 = 4/9

So, they get 4/9 of a room done in 1 hour.

Number of hours needed ⇒

1 ÷ 4/9 = 2 1/4  

Answer: They need 2 1/4 hours to paint the room.

0,6

Step-by-step explanation:

Answer:

Substitute 0 for the x-value in the equation and solve for y. The result is y = 6, so the y-intercept is at (0, 6). Next, substitute 0 for the y-value in the equation and solve for x. The result is x = 16, so the x-intercept is at (16, 0).

Answer: 7.58 years

Step-by-step explanation:

When it comes to finding out how long it will take for an investment to double, one can use the Rule of 72.

The Rule of 72 estimates the amount of time it will take to double an investment when you divide 72 by the interest rate:

= 72 / r

= 72 / 9.5

= 7.58 years
