Answer:

The value of a is 4 ⇒ D

Step-by-step explanation:

In the system of equations

∵ y = ax ⇒ (1)

∵ ax + y = 16 ⇒ (2)

∵ The solution of the system is (2, 8)

∴ x = 2 and y = 8

→ To find the value of a substitute x by 2 and y by 8 in equation (1) or (2)

∵ y = ax

∵ y = 8 and x = 2

∴ 8 = a(2)

∴ 8 = 2a

→ Divide both sides by 2

∵ [tex]\frac{8}{2}[/tex] = [tex]\frac{2a}{2}[/tex]

∴ 4 = a

∴ The value of a is 4

Answer:

6^(7/3)

Step-by-step explanation:

Given 6^2 * cubed_root(6).

The cube root is also equal to 6^1/3

[Multiply the terms, add the powers]

6^2 * 6^(1/3) = 6^(2 + 1/3) = 6^(7/3)

Answer:

(-1,-2, -3, -4)

Step-by-step explanation:

-15 < 3n <6

-15 < 3 (-1,-2, -3, -4) <6

3 • -1 = -3

3 • -2 = -6

3 • -3= - 9

3 • -4 = -12

so all these answer still make -15 the lowest value and 6 the highest value.

Answer:

Answer:

the graph of w passe through point (8,-6)

Step-by-step explanation:

When you draw a line through points (-5, 7) and (3, -1) points (8,-6) also meets the line segment at the very bottom.

Answer:

The graph of w passes through (8,-6)  (FIRST ANSWER)

Step-by-step explanation:

The equation of the graph is -1x+2, therefore no other answer works

The slope is -1, not 2

The Y-intercept is (0,2), NOT the X-intercept

The zero is 2, not -1

Therefore, the only correct answer is The graph of w passes through (8,-6)

it got the smallest mass among all options.

Answer:

2,322,775

Step-by-step explanation:

[tex] a_1=4\\\\

a_i=a_{i-1}+11\\\\

\implies a_2=a_{2-1}+11\\a_2= a_1+11 \\a_2= 4+11 \\a_2= 15\\\\

d = a_2-a_1 \\d= 15-4 \\d= 11\\\\

S_{650}=?\\\\

\implies n = 650\\\\[/tex]

By the formula of sum of an Arithmetic Sequence

[tex] S_n= \frac{n}{2} [2a_1+(n-1)d]\\\\

S_{650}= \frac{650}{2} [2\times 4+(650-1)\times 11]\\\\

S_{650}= 325 [8+649\times 11]\\\\

S_{650}= 325 [8+7,139]\\\\

S_{650}= 325\times 7,147\\\\

Answer:

l = 29.4 yards

w = 66.8 yards

General Formulas and Concepts:

Step-by-step explanation:

Step 1: Define

P = 163 yards

w = 2l + 8

l = l

Step 2: Set up equation

P = 2w + 2l

163 = 2(2l + 8) + l

Step 3: Solve for l

Step 4: Find w

Answer:

8708 feet

Step-by-step explanation:

The Mariana Trench in the Pacific Ocean is about 36,201 feet deep. The Puerto Rico Trench in the Atlantic Ocean is about 27,493 feet deep.

We need to find how many feet deeper is the Mariana Trench than the Puerto Rico Trench.

As Mariana Trench and Puerto Rico Trench is deep.

h = -27,493-(-36,201)

h = 8708 feet

So, Mariana Trench is 8708 feet deeper than Puerto Rico Trench
