Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{ - 1 }}}}}

Step-by-step explanation:

Given, f( x ) = 2x - 3

Here, we assume the value of x as 1

Now, <u>Finding </u><u>f</u><u> </u><u>(</u><u> </u><u>1</u><u> </u><u>)</u>

\sf{f(1) = 2 \times 1 - 3}

Multiply the numbers : 2 and 1

⇒\sf{f(1) = 2 - 3}

Subtract the numbers : 3 from 2

⇒\sf{f(1) =  - 1}

Hope I helped!

Best regards!!

Jordan is saving to buy a computer that costs $425. So far she has saved $125, and she adds $20 to her savings each week. How ma
Ber [7]

Answer:

15 more weeks

Step-by-step explanation:

425 - 125 (what shes already saved)

300 divided by 20 (amount shes saving each week)

Result is 15, so 15 more weeks.

Hope this helped :)

If you mean how many weeks total, 125 according to the 20 dollars a week would bring it 22 weeks i think.. since the answer answer is 21.2 weeks exactly when you divide 425 by 20.

Find the x- and y-intercepts for the linear equation –3x + 4y = 24.
Sav [38]

Answer:

x- intercept = - 8, y- intercept = 6

Step-by-step explanation:

To find the x- intercept let y = 0 and solve for x

- 3x + 4(0) = 24

- 3x = 24 ( divide both sides by - 3 )

x = - 8 ← x- intercept

To find the y- intercept let x = 0 and solve for y

- 3(0) + 4y = 24

4y = 24 ( divide both sides by 4 )

y = 6 ← y- intercept

Northern Bank has two types of account. Both accounts pay compound interest. Cash savings account Interest 2.5% per annum Shares
musickatia [10]

Answer: Ben will have the most interest.

Step-by-step explanation:

Ali after 3 years.

To use compound interest, the formula is:

= Investment * ( 1 + rate) ^ no. of periods

= 2,000 * ( 1 + 2.5%)³

= £‭2,153.78

Interest = Amount after 3 years - investment

= 2,153.78 - 2,000

= £153.78

Ben after 3 years.

= 1,600 * (1 + 3.5%)³

= £1,773.95

Interest = 1,773.93 - 1,600

= £173.93
