A. Multiply both sides by 2
B. Subtract 28 from both sides
C. Divide both sides by 2
D. add 28 to both sides

Answer:

n<2

Step-by-step explanation:

6.2n<2n+8.4

Move variable to the left hand side and change its sign

6.2n - 2n < 8.4

Combine like terms

4.2n < 8.4

divide both side by 4.2

n < 2

Answer:

FV= $1,545

Step-by-step explanation:

Giving the following information:

Elena deposits $1,500 in a savings account that earns 3.0% simple interest per year.

To calculate the nominal value of the account after one year, we need to use the following formula:

FV= (P*r*t) + P

FV= future value

P= principal

r= interest rate

t= 1

FV= (1,500*0.03*1) + 1,500

FV= $1,545

Answer:

2x^2-6x-4

Step-by-step explanation:

(7x2 + 4x - 9)

-(5x2 + 10x - 5)

=

7x^2-5x^2=2x^2

4x-10x=-6x

-9-(-5)=-4

thus, your answer is 2x^2-6x-4

The equation of function notation for the relation will be,

⇒ y = x - 3

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Table is shown in figure.

Two points on the table are (3, 0) and (4, 1).

Now,

Since, The equation of function passes through the points,

(3, 0) and (4, 1).

So, We need to find the slope of the function.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 0) / (4 - 3)

m = 1

Thus, The equation of function with slope 1 is,

⇒ y - 0 = 1 (x - 3)

⇒ y = x - 3

⇒ y = x - 3

Thus, The equation of function notation for the relation will be,

⇒ y = x - 3

Answer:

x = 8

Step-by-step explanation:

If equiangular, than all angles are equal

Thus, we have that;

7x + 4 = 12x-36

12x-7x = 36 + 4

5x = 40

x = 40/5

x= 8

Answer:

14.83 meters

Step-by-step explanation:

Given that :

Angle of elevation (α) = 56°

Distance between observer and foot of tree = 10 meter.

Height of tree =?

Using trigonometry :

The height (h) of the tree can be obtained using :

Tan α = opposite / Adjacent

Tan(56°) = h / 10

1.4825609 = h / 10

Multiply both sides by 10

1.4825609 * 10 = h

14.8256 = h

Hence, the height of the tree is 14.83 m(2 decimal places).

Answer:

21

Step-by-step explanation:

subtract 9 on both sides to make your x axis by itself

y=mx+b

since -3y and -63 will cancel out each other and make a positive when you divide

-3y /63

y=21

also your when the x is alone it is always 1

Answer:

need what done?

Step-by-step explanation:

The cross-sectional area of the shaft is 314 mm²

The outside diameter (d₂) = 6 cm = 60 mm

The inside diameter (d₁) = 4 cm = 40 mm

The cross sectional area of the shaft (A) is given by:

A = π(d₂ - d₁)²/4

Substituting values:

A = π(60 - 40)²/4

Simplifying the equation:

A = 314 mm²

The cross-sectional area of the shaft is 314 mm²
