True or false please help thank you

Leni [432]

Answer:

True.

See below for explanation.

Step-by-step explanation:

Reason 1

When we solve the equation by combining both equations in one, the variable will become 0.

Proof

$\begin{cases} y = 4x - 3 \\ y = 4x - 5 \end{cases} \\ 4x - 3 = 4x - 5$

Combine like terms.

$4x - 4x = - 5 + 3 \\ 0 = - 2$

See that the equation is false no matter which numbers you substitute in x-term.

Reason 2

Both graphs are parallel and don't have any intercepts to each others.

See the attachment below for graphs.

Since both graphs do not really have intercepts, that means they do not provide any solutions. Hence, no solutions.

Amy invest $3,000 in a savings account that pays 2.35% simple annual interest .She makes no other deposits or withdrawals for 3.

Reil [10]

A. The statement Amy's account will earn $246.75 in interest is True

B. The statement Amy's account will be worth $2,753.25 after 3.5 years

is False

C. Amy's account would earn $15.75 more in interest if the annual

interest rate were raised to 2.5% is True

Step-by-step explanation:

Simple interest rule is I = Prt , where I is the interest, p is the money

invested, r is the annual rate in decimal and t is the time

The given is:

1. The money invested is $3,000

2. The simple annual interest is 2.35%

3. The time is 3.5 years

∵ P = 3000

∵ r = 2.35 ÷ 100 = 0.0235

∵ t = 3.5

- Substitute these values in the rule above to find the interest

∴ I = 3000(0.0235)(3.5)

∴ I = 246.75

A. Amy's account will earn $246.75 in interest ⇒ True

To find the total money that Amy has after 3.5 years add the money

invested to the interest

∵ Total money = P + I

∵ P = 3000 and I = 246.75

∴ Total money = 3000 + 246.75

∴ Total money = 3246.75 dollars

B. Amy's account will be worth $2,753.25 after 3.5 years ⇒ False

∵ P = 3000

∵ r = 2.5 ÷ 100 = 0.025

∵ t = 3.5

- Substitute these values in the rule above to find the interest

∴ I = 3000(0.025)(3.5)

∴ I = 262.5

∵ I of 2.35% = 246.75

∴ The difference = 262.5 - 246.75 = 15.75

C. Amy's account would earn $15.75 more in interest if the annual

interest rate were raised to 2.5% ⇒ True
