Step-by-step explanation:

products of

$2 \frac{2}{3} \times 3\frac{3}{4} \\ = \frac{2 \times 3 + 2}{3} \times \frac{3 \times 4 + 3}{4} \\ = \frac{8}{3} \times \frac{15}{4} \\ = 10$

Hope it will help :)

-7(a - 3) = 11 - 7a<br> what’s the answer

natali 33 [55]

Answer:

the statement is false there is no solution

Step-by-step explanation:

step 1 -7(a-3)=11-7a

step 2 -7a+21=11-7a

step 3 cancel out the -7a's

step 4 you are left with 21=11 which does not work so it is false

For 50 Points!!!!!!!!!

dolphi86 [110]

Hello!

First you have to find what the temperature was at the 3 stages

It started at 87

Then went down 10

87 - 10 = 77

Then up 17

77 + 17 = 94

Then you take the difference from the current temperature from the lowest temperature

94 - 77 = 17

The answer is D

Hope this helps!

Can someone help idk if this is right

navik [9.2K]

Answer:

$a_n=-3 \cdot a_{n-1}$

$a_1=2$

You gave the explicit form.

Step-by-step explanation:

You gave the explicit form.

The recursive form is giving you a term in terms of previous terms of the sequence.

So the recursive form of a geometric sequence is $a_n=r \cdot a_{n-1}$ and they also give a term of the sequence; like first term is such and such number. All this says is to get a term in the sequence you just multiply previous term by the common ratio.

r is the common ratio and can found by choosing a term and dividing by the term that is right before it.

So here r=-3 since all of these say that it does:

-54/18

18/-6

-6/2

If these quotients didn't match, then it wouldn't be geometric.

Anyways the recursive form for this geometric sequence is

$a_n=-3 \cdot a_{n-1}$

$a_1=2$

Complete the square to solve 4x2 + 24x = 4.

igomit [66]

Answer:

x = - 3 ± $\sqrt{10}$

Step-by-step explanation:

Given

4x² + 24x = 4 ( divide through by 4 )

x² + 6x = 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 1 + 9

(x + 3)² = 10 ( take the square root of both sides )

x + 3 = ± $\sqrt{10}$ ( subtract 3 from both sides )

x = - 3 ± $\sqrt{10}$
