46 less than -8 times a number is the same as 8 less than -6 times the number

sertanlavr [38]

Answer:

-19

Step-by-step explanation:

First we set the equation up:

-8X - 46 = -6X - 8

Then we simplify:

-2X = 38

Then we get the answer by dividing 38 by -2:

X = -19

Complete the table of values.

ohaa [14]

Step-by-step explanation:

what ? you cannot do even simplest subtractions ?

what is it you don't understand here ?

how such a function works ?

you take every value for x (the input variable or argument), put it in place of the "x" (this is nothing else than a placeholder for the actual values) and then perform the mathematical operations. y is then the result of that.

x = 0

y = 0 - 7 = -7

the ordered pair of (x, y) is (0, -7)

x = 1

y = 1 - 7 = -6

(1, -6)

x = -3

y = -3 - 7 = -10

(-3, -10)

x = -5

y = -5 - 7 = -12

(-5, -12)

Which equation corresponds to the statement, to more than a number equivalent to Y

Mariana [72]

Answer:

English statement 'two more than a number equivalent to Y' can be algebraically represented as:

y = x + 2

Step-by-step explanation:

Two more than a number means we need to add 2 to a number.

Let suppose the number be = x

Two more than the number 'x' = x+2

As it is stated that two more than a number equivalent to Y.

Equivalent means something is equal to the given expression.

Mathematically, the 'equivalent' is represented by the symbol '='.

Thus, the English statement 'two more than a number equivalent to Y' can be algebraically represented as:

y = x + 2

What is the expression for "the difference between 5 times a number and twice that number"?

ycow [4]

Hey there :)

Before translating the sentence into mathematics, let r represent 'a number'

5 times a number = 5r
2 times that number = 2r

The difference between them = 5r - 2r

* Your equation
5r - 2r

* Solving the equation
= 5r - 2r
= 3r

Dylan borrowed $2100 from the bank for 15 months. The bank discounted the loan at 2.6%. How much was the interest? $ State your

melomori [17]

Answer:

actual rate of interest is 2.08 %

Step-by-step explanation:

Given data

borrowed = $2100

time = 15 months

rate = 2.6%

to find out

interest and receive from the bank and actual rate of interest

solution

we know bank discounted the loan at 2.6%

so interest will be 2.6% of $2100

that is = 2.6/100 × 2100

interest = $54.60

so receive from the bank is borrowed money - interest

receive = 2100 - 54.60

receive from the bank is $2045.40

and we can say that interest is directly proportional to time

so interest of 12 months / interest of 15 month = 12 month time/ 15 month time

here interest of 12 months = 12/15 × interest of 15 month

interest of 12 months = 12/15 × 54.60

interest of 12 months is $43.68 (annually)

now we can calculate actual rate of interest

that is = interest / borrowed money × 100

actual rate of interest = 43.68/2100 × 100

actual rate of interest is 2.08 %
