Answer:

The equal sign is generally placed at the separation between the left hand side and the right hand side

Step-by-step explanation:

Basically a typical equation has two parts, and one part is seen to be equal to the other part, and they are:

<h3>1. The left hand side</h3><h3>2. The right hand side</h3>

Generally equations are expressed algebraically,that is using letters/ alphabets and symbols to express mathematical relations

The left hand side mostly is the solution of the equation, while the right hand side contains symbols, alphabets used to find solution to the equation.

Make graph of y=4x-7

maksim [4K]

Answer:

<h2>Explanation:</h2><h2>You know that when x = 0, y = -7 (because y = 4(0)-7 = -7, or you just know the fact that the constant number shows the y-value of the y-intercept). Therefore, you can plot that point on the graph:</h2>

Suppose that you want to mix two coffees in order to obtain 100 pounds of a blend. If x represents the number of pounds of coffe

Fantom [35]

Answer:

The required expression that represents the number of pound of coffees B is $100-x$

Step-by-step explanation:

Consider the provided information.

You want to mix two coffees in order to obtain 100 pounds of a blend.

Let x represents the number of pounds of coffee A and y represents the number of pounds of coffee B.

The obtained weight is 100 pounds.

$x+y=100$

$y=100-x$

Hence, the required expression that represents the number of pound of coffees B is $100-x$

A bank features a savings account that has an annual percentage rate of r=5.2% with interest compounded quarterly. Marcus deposi

Alexxx [7]

Answer:

(A) P = 8,500 , r = 0.052 , n = 4

(B) $12203.47

Step-by-step explanation:

* Lets explain how to solve the problem

- The annual percentage rate is R = 5.2%

- The interest is compounded quarterly

- Marcus deposits $8,500

- The account balance can be modeled by the exponential formula

S(t) = P(1 + r/n)^nt, where

# S is the future value

# P is the present value

# r is the annual percentage rate written as a decimal

# n is the number of times each year that the interest is compounded

# t is the time in years

* Lets solve the problem

∵ P is the present value

∵ Marcus deposits $8,500

∴ The present value is 8,500

∵ r is the annual percentage rate written as a decimal

∵ The annual percentage rate is 5.2%

∴ r = 5.2/100 = 0.052

∵ n is the number of times each year that the interest is compounded

∵ The interest is compounded quarterly

∴ n = 4

# (A)

* P = 8,500 , r = 0.052 , n = 4

# (B)

∵ S(t) = P(1 + r/n)^nt

∵ t is the time in years

∵ Marcus invests the money for 7 years

∴ t = 7

∴ S = 8500(1 + 0.052/4)^(4 × 7)

∴ S = 8500(1.013)^28 = 12203.47

* Marcus will have $12203.47 in 7 years
