Answer:

The answers are

→ <u><em>a. 15</em></u>

→ <u><em>b. 27</em></u>

→ <u><em>c. 4</em></u>

→ <u><em>d. 72</em></u>

→ <u><em>e. 2</em></u>

→ <u><em>f. 9</em></u>

→ <u><em>g. 1</em></u>

Step-by-step explanation:

Given expressions:

a. 7 + 2³

b. 9 • 3¹

c. 20 - 2⁴

d. 2 • 6²

e. 8 • (1/2)²

f. 1/3 • 3³

g. (1/5 • 5)⁵

<h2>Solve:</h2>

a. 7 + 2³

7+2^3

2^3 = 8

8 + 7 = 15

Hence, <u><em>15</em></u> is your answer.

b. 9 • 3¹

9*3^1

⇒ 9*(3)

⇒ 27

Hence, <u><em>27</em></u> is your answer.

c. 20 - 2⁴

20 - 2^4

2^4 = 16

20-16 = 4

Hence, <u><em>4</em></u> is your answer.

d. 2 • 6²

2 * 6^2

⇒ 2*6^2

⇒ 2*(6*6)

⇒ 72

Hence, <u><em>72</em></u> is your answer.

e. 8 • (1/2)²

8 * (\frac{1}{2})^2

⇒ 8*((\frac{1}{2})*(\frac{1}{2}))

⇒ 2

Hence, <u><em>2</em></u> is your answer.

f. 1/3 • 3³

\frac{1}{3} * 3^3

⇒ 9

Hence, <u><em>9</em></u> is your answer.

g. (1/5 • 5)⁵

(\frac{1}{5} * 5)^5

⇒ 1*1*1*1*1

⇒ 1

Hence, <u><em>1</em></u> is your answer.

Please help me with this please and thank you
Alina [70]

Step-by-step explanation:

y = ax^n + bx^(n-1) ... + z

(0, 1) tells us that the constant term z = 1.

because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.

for the other pairs I strongly suspect

(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3

(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9

so, the fitting equation is

y = 2x² + 1

How do I write the sum of 6x and 2x is at least 39 ?
tatiyna
<h2>Put x = \dfrac{39}{8} I write the sum of 6x and 2x is at least 39 .</h2>

Step-by-step explanation:

We have,,

6x and 2x

To find, the value of x = ?

According to question,

The sum of 6x and 2x is at least 39

∴ 6x + 2x = 39

⇒ 8x = 39

⇒  x = \dfrac{39}{8}

∴ The value of x = \dfrac{39}{8}

Thus, put x = \dfrac{39}{8} I write the sum of 6x and 2x is at least 39 .

Solve for w. 5w + 9z = 2z + 3w w = w equals negative StartFraction 7 Over 2 EndFraction z.Z w = w equals negative StartFraction
TEA [102]

Answer:

w = -7z/2

Step-by-step explanation:

We need to solve for w in terms of z.

The equation given is:

5w + 9z = 2z + 3w

Collect like terms:

5w - 3w = 2z - 9z

2w = -7z

w = -7z/2
