\text{Hey there!}

\text{If k = 5 the replace the 'k' value with 5}

\text{4(5)}^2+3

\text{(5)}^2=5\times5=25

\text{4 (25)+ 3 = ?}

\text{4 (25) = 25 + 25 + 25 + 25 = 100}

\text{100 + 3 = 103}

\boxed{\boxed{\bf{Your\ answer: 103}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}

Answer:

103

Step-by-step explanation:

Evaluate 4k2 + 3

To evaluate 4k² + 3, when k = 5, which means when you sees k, put 5 in replacement

4k² + 3 = 4(5)² + 3

4(5×5) + 3

4(25) + 3

open the bracket

4 × 25 = 100

∴ 100 + 3 = 103

I’m not sure how to solve “system of equations”
natka813 [3]

Hey there! :)

Answer:

(2, -2)

Step-by-step explanation:

-2x + y = -6

4x + 3y = 2

We can begin by setting the first equation equal to y:

-2x + y = -6

Add 2x to both sides:

y = 2x - 6

Plug this equation for y into the second equation:

4x + 3(2x - 6) = 2

Distribute:

4x + 6x - 18 = 2

Combine like terms:

10x = 20

x = 2

Plug the value of 'x' into an equation to solve for 'y':

-2(2) + y = -6

-4 + y = -6

y = -2

Therefore, the solution is (2, -2)

Answer:

figure skates will be $1 cheaper.

Explanation:

<u>given equation</u>:

  • to rent figure skates : f(x) = 1.50x + 2
  • to rent hockey skates : h(x) = 2x +1.5

<u>solve for rent of figure skates</u>:

f(x) = 1.50x + 2.00

f(3) = 1.50(3) + 2.00

f(3) = 6.5

<u>solve for rent of hockey skates</u>:

h(x) = 2x + 1.5

h(3) = 2(3) +1.5

h(3) = 7.5

<u>cheaper - figure skates than hockey skates</u>:

$7.5 - $6.5

$1

Find the prime factorization of 120.
artcher [175]

Answer:

(7/8 - 4/5)^2 = 9/

1600

= 0.005625

Step-by-step explanation:

Subtract: 7/

8

- 4/

5

= 7 · 5/

8 · 5

- 4 · 8/

5 · 8

= 35/

40

- 32/

40

= 35 - 32/

40

= 3/

40

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - seven eighths minus four-fifths = three fortieths.

Exponentiation: the result of step No. 1 ^ 2 = 3/

40

^ 2 = 32/

402

= 9/

1600

In words - three-fortieths squared = nine one-thousand six-hundredths.
