The sum of two numbers is 5. The difference of two numbers is -1. Find the numbers
Drupady [299]

Answer:

The numbers are 2 and 3.

Step-by-step explanation:

The smaller number would have been 1 less than the bigger number so that if for example the smaller number is 1 and the bigger number is 2, their difference would have been 1-2 = -1

5 is an odd number so if it were to be divided into two integers, one would be more than the other, namely 2 and 3.

If you double-check their difference:

2-3 = -1

Thus, the two numbers are 2 and 3.

Investments Suppose that you have $4000 to invest and you invest x dollars at 10% and the remainder at 896, write expressions in
Darina [25.2K]

Answer:

Step-by-step explanation:

you have $4000 to invest and you invest x dollars at 10% and the remainder at 8℅.

a) an expression in x that represent the amount invested at 8% is

4000 - x

b) The The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

P = $x

R = 10%

Assuming the investment is for 1 year, then interest,

I = (x × 10 × 1)/100

I = $0.1x

c) P = 4000 - x

R = 8℅

I = [(4000 - x) × 8 × 1)]/100

I = (32000 - 8x)/100

I = 320 - 0.08x

d) the total interest earned is

I = 0.1x + 320 - 0.08x

I = 0.02x + 320

Can someone help me on this question please
IgorLugansk [536]

Answer:

y = -2x + 5 [ 1st option ]

Step-by-step explanation:

Consider any two points , say

  • (1,3)
  • (2,1)

Firstly let's find the slope of the line as ,

=> m = y₁ - y₂ / x₁ - x₂

=> m = 3-1 / 1-2

=> m = 2/-1

=> m = -2

Third point is, (3 , -1) . Using slope point form .

=> y - y₁ = m ( x - x₁ )

=> y - (-1) = -2( x - 3)

=> y + 1 = -2x +6

=> y +2x +1-6=0

=> y +2x -5 = 0

=> y = -2x + 5

On looking at options first one is correct

<h3><u>Hence</u><u> the</u><u> </u><u>equation</u><u> of</u><u> line</u><u> </u><u>is </u><u>y </u><u>=</u><u> </u><u>-2x </u><u>+</u><u> </u><u>5</u><u>.</u></h3>
