An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $4150 and her st
zzz [600]

Answer: The required percentage would be 5.4%.

Step-by-step explanation:

Since we have given that

Worth of Company A = $4150

Worth of Company B = $6820

So, increase in Company A = 6%

increase in Company B = 5%

According to question, it becomes,

0.06\times 4150+0.05\times 6820\\\\=249+341\\\\=590

So, the total percentage increase in the investor's stock account would be

\dfrac{590}{4150+6820}\times 100\\\\=\dfrac{590}{10970}\times 100\\\\=5.378\%

Hence, the required percentage would be 5.4%.

If p(x) = x²+x+6 and q (x)=3x-1 find q ( 1/4)
erma4kov [3.2K]
<h3>Answer is    -1/4</h3>

Work Shown:

q(x) = 3x - 1

q(1/4) = 3(1/4) - 1 ... replace x with 1/4

q(1/4) = 3/4 - 1

q(1/4) = 3/4 - 4/4 ... rewrite 1 as 4/4

q(1/4) = (3-4)/4

q(1/4) = -1/4

The p(x) function is never used.

S is the midpoint of RT. <br> If RS = 4x - 3 and RT = 6x - 4,<br> what’s the value of ST?
Georgia [21]

Answer:

R__S__T

RT = RS + ST

6x – 4 = ( 4x – 3) + ST

(6x – 4 ) – ( 4x – 3 ) = ST

(6x – 4 ) +( – 4x + 3 ) = ST

2x – 1 = ST

ST = 2x – 1

RS=ST

4x – 3 = 2x – 1

4x – 2x = – 1 +3

2x = 2

x= 2/2

x =1

ST = 2x – 1 = 2(1) – 1 =2 ‐ 1 = 1

ST = 1

I hope I helped you^_^

I need ur smart brain power!!!!!
Andrej [43]

Answer:

y = -2x -3

Step-by-step explanation:

I love slope-intercept form! lol

y =mx +b

so we have 2 points given: (-1,5) and (4,-5)

to find the SLOPE of the slope-intercept form, we need to subtract and divide

(-5-5)/(4+1)

-10/5= -2 which is our slope

now! lets translate this info into point slope form. y - y1 = m (x - x1)

(-1,5) and we kno the slope is -2.

y - 5 = -2 (x - (-1))

y-5 = -2(x + 1)

y-5 = -2x -2

add five

y = -2x -3    we are back to slope intercept form! YAY!
