Steps to solve:

6 * 4 + 2 / 2 - 7

~Multiply

24 + 2 / 2 - 7

~Divide

24 + 1 - 7

~Add

25 - 7

~Subtract

18

In step one, she added instead of multiplied which caused her to get the wrong answer.

Best of Luck!

Hey there! I'm happy to help!

Step 2 is incorrect. She added 4 and 2 first, but you are supposed to multiply and divide first. Then she multiplied 6 and 6, which is 36. Then she divided 36 and 2, which is 18, and then she subtracted 7, giving her 11. Step 2 is what threw the whole thing off.

Here is what Sandy should have done.

STEP 1: 6·4+2÷2-7

STEP 2: 24+1-7

STEP 3: 25-7

STEP 4: 18

I hope that this helps! Have a wonderful day! :D

For the exponential equation <img src="https://tex.z-dn.net/?f=y%20%3D%203.4%280.66%29%5Ex" id="TexFormula1" title="y = 3.4(0.66

Answer:

Option: B is the correct answer.

B) Decay, y- intercept = 3.4, rate is 34%

Step-by-step explanation:

We are given an exponential equation as follows:

$y=3.4(0.66)^x$

We know that any exponential function of the type:

$y=ab^x$

is growth function if: b>1

and is a decay function if 0< b< 1

Hence, here we have: b=0.66<1

Hence, the function is a decay function.

Also, we know that the y-intercept of a function is the point where x=0

Hence, we take x=0

we have: $y=3.4\times (0.66)^0\\\\\\y=3.4$

Hence, the y-intercept is: 3.4

Also, the rate of a function is denoted by 'r'

where b=1-r

⇒ 0.66=1-r

⇒ r=1-0.66

⇒ r=0.34

Hence, the rate is: 34%

option: B is the correct answer.

I need help solving this problem

Answer:

$(x,f(x)) = (-1,8)$ -- Another point

$a = 8$

Step-by-step explanation:

Given

$f(x) = a|x|$

$(x,f(x)) = (1,8)$

Solving (a): Another point

Substitute 1 for x and 8 for f(x) in $f(x) = a|x|$

$8 = a|1|$

Remove absolute bracket

$8 = a*1$

$8 = a$

$a = 8$

Substitute 8 for a in $f(x) = a|x|$

$f(x) = 8|x|$

Let x = -1

$f(x) = 8|-1|$

Remove absolute bracket

$f(x) = 8*1$

$f(x) = 8$

So, another point is:

$(x,f(x)) = (-1,8)$

Solving (b): The value of a

This has been solved in (a) above

$a = 8$
