Answer:

The pair is not included in the graph of y= 3x+6 ⇒ <u>(3,12) & (6,18)</u>

Step-by-step explanation:

given ⇒ y = 3x + 6

It is a linear equation, can be graphed easily by supposing two point of x and find the corresponding value of y ⇒ see the table.

See the attached figure.

As shown on the figure, the line passes through all the points except

Answer:

(3,12)

Step-by-step explanation:

you would put the 12 as y then 3×3=9+6=15 and 12 doesn't equal 15

Yes

Set the total cost toy, the number of books is x.

So, y= 200+2x

so cost is a dunction of the number of books

Hope this helps you!!!!! :D

The 4th and 8th term of a G.P. are 24 and 8/27 respectively. find the 1st term and common ratio

beks73 [17]

Answer:

see explanation

Step-by-step explanation:

The n th term of a geometric progression is

• $a_{n}$ = a₁ $r^{n-1}$

where a₁ is the first term and r the common ratio

given a₄ = 24, then

a₁ $r^{3}$ = 24 → (1)

Given a₈ = $\frac{8}{27}$ , then

a₁ $r^{7}$ = $\frac{8}{27}$ → (2)

Divide (2) by (1)

$r^{4}$ = $\frac{\frac{8}{27} }{24}$ = $\frac{1}{81}$

Hence r = $\sqrt[4]{\frac{1}{81} }$ = $\frac{1}{3}$

Substitute this value into (1)

a₁ × ( $\frac{1}{3}$ )³ = 24

a₁ × $\frac{1}{27}$ = 24, hence

a₁ = 24 × 27 = 648

What is the value of x in theequation 2.5 (6x - 4) = 10 + 4 (1.5 +0.5 x)?

Zarrin [17]

Answer:

x = 2

Step-by-step explanation:

Let's solve your equation step-by-step.

2.5(6x−4)=10+4(1.5+0.5x)

Step 1: Simplify both sides of the equation.

2.5(6x−4)=10+4(1.5+0.5x)

(2.5)(6x)+(2.5)(−4)=10+(4)(1.5)+(4)(0.5x)(Distribute)

15x+−10=10+6+2x

15x−10=(2x)+(10+6)(Combine Like Terms)

15x−10=2x+16

Step 2: Subtract 2x from both sides.

15x−10−2x=2x+16−2x

13x−10=16

Step 3: Add 10 to both sides.

13x−10+10=16+10

13x=26

Step 4: Divide both sides by 13.

x=2
