Consider the equation 4x + 1 = 2x + 5

Mathematics

Darya [45]3 years ago

(a) Without solving the equation we can't determine whether its true or false.

(b) If x = 3

4x + 1 = 2x + 5

4(3) + 1 = 2(3) + 5

12 + 1 = 15 + 5

13 = 20

No, if x = 3, the equation will not be true.

(c) 4x + 1 = 2x + 5

4x - 2x = 5 - 1

2x = 4

x = 4/2

x = 2

This shows that x = 2 makes the equation true.

Answer: C) $1951.53

<u>Step-by-step explanation:</u>

A=P(1+r)^{t}

  • A is amount accrued (final balance)
  • P is the Principal (original amount deposited)
  • r is the rate (in decimal form)
  • t is the number of years

A=1500(1+0.068)⁴

  = 1500(1.068)⁴

  = 1951.53

Can someone help me?
Papessa [141]

Answer:

2x - 2y = 24 \\ 2(x - y) = 24 \\ x = 12 + y......eq(1) \\ 4x + 7y =  - 40......eq(2) \\ substituting \: the \: value \: of \: x \: in \: eq(2) \\ 4(12 + y) + 7y =  - 40 \\ 48 + 4y + 7y =  - 40 \\ 11y =  - 40 - 48 \\ y =  \frac{ - 88}{11}  \\ y =  - 8 \\ putting \: the \: value \: of \: y \: im \: eq(1) \\ x = 12 - 8 \\  = 4

Step-by-step explanation:

3x-2y=24......eqi

x+2y=48........eqii

now solving eq i&ii

4x=72

x=72/4

x=18

now putting the value of x in eqii

18+2y=48

2y=48-18

y=30/2

y=15
