Hope this helps :3

Answer:

i.) 2/3

Step-by-step explanation:

-6x+5=1

move constant to the right and change its sign.

= -6x = 1-5

calculate

= -6x = -4

divide both sides of the equation by -6

= -6x/6 = -4/-6

=2/3.

Step-by-step explanation:

[tex]\frac{1}{2}-3(\frac{1}{2}+1)^{2} = \frac{1}{2}-3(\frac{1}{2}+\frac{1*2}{1*2} )^{2}[/tex]

                     [tex]=\frac{1}{2}-3(\frac{1}{2}+\frac{2}{2} )^{2}\\\\\\=\frac{1}{2}-3(\frac{3}{2})^{2}\\\\\\=\frac{1}{2}-3*\frac{9}{4}\\\\\\=\frac{1*2}{2*2}-\frac{27}{4}\\\\\\=\frac{2}{4}-\frac{27}{4}\\\\\\=\frac{2-27}{4}\\\\=\frac{-25}{4}\\\\\\= -6\frac{1}{4}[/tex]

Answer:

the answer is C.

Step-by-step explanation:

It is C because you are already dividing the numbers so you are going to multiply them and your answer for the division should be the same answer on the multiplication.

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8

Answer:

Kaylynn=$270

Amanda=$250

Step-by-step explanation:

Kaylynn=8.25x32.5=268.125 but since its estimated we round it up to 270.

Amanda=8.75x28.5=249.375 but since its estimated we round up to 250.

1.in triangle ADB and ADC

a. AB=AC                                    a.given

b.BD=CD                                     b. radii of same circle

c. AD=AD                                      c. common side

2. ∵triangle ADB is congurent to 2. by S.S.S axiom

  ADC

Answer:

AD cuts BC at I => I is the midpoint of BC => BI = CI

ΔAIB and ΔAIC have:

AB = AC

BI = CI

m∠ABC = m∠ACB ( because ΔABC is a  isosceles triangle)

=> ΔAIB ≅ ΔAIC (sas)

=> m∠BAD = m∠CAD

ΔADB and ΔADC have:

m∠BAD = m∠CAD

AB = AC

AD is the common edge

=> ΔADB ≅ ΔADC (sas)

Answer:

B ≤ 3.7

Step-by-step explanation:

Total money with Alonso = $21

Cost of Eggs = $2.50

Cost of Avocados in bags of 3 = $5

Let

B = number of bags of avocados that Alonso buys.

The inequality is:

Cost of Eggs + Cost of Avocados in bags of 3 ≤ Total money with Alonso

2.50 + 5B ≤ 21

5B ≤ 21 - 2.50

5B ≤ 18.5

B ≤ 18.5/5

B ≤ 3.7

The number of bags of avocados Alonso bought can be represented by B ≤ 3.7

Answer:

1) The inequality that describes this scenario is 2.50+5B≤21

2) Alonso can afford at most 9 avocados.

Answer: 17 years

Step-by-step explanation:

Exponential equation for compund amount( compunded continuously):

[tex]A=Pe^{rt}[/tex] , where P= Principal value , r= rate of interest , t= time.

Given: A= 2P

r =4%= 0.04

To find : t

Substitute all values in the formula , we get

[tex]2P=Pe^{0.04t}\\\\\Rightarrow\ 2=e^{0.04t}[/tex]

Taking natural log on both sides

[tex]\ln2=\ln e^{0.04t }\\\\\Rightarrow\ 0.693147=0.04t\\\\\Rightarrow\ t=\dfrac{ 0.693147}{0.04}\\\\\Rightarrow\ t=17.3286\approx17[/tex]

hence, it will take 17 years (approx).

Answer:

x^2+y^2-32x+24y+375=0

Step-by-step explanation:

Equation of circle with given centre (h,k) and radius=r is

(x-h)^2+(y-k)^2=r^2

Given centre are=(16, - 12) and radius= 5

So equation of circle=

(x-16)^2+(y- -12)^2=5^2

x^2-32x+256+y^2+24y+144=25

x^2+y^2-32x+24y+375=0

Answer

Answer:

Jane invested $37,000 in Fund B.

Step-by-step explanation:

Let;

IA = Amount invested in Fund A = $6,000

IB = Amount invested in Fund B = ?

PA = Amount of profit from Fund A = IA * 8% = $6,000 * 8% = $480

PB = Amount of profit from Fund B = IB * 2%

Therefore, we have:

Total profit = PA + PB = $1220 ........................ (1)

Substitute the relevant values into equation (1) and solve for IB, we have:

$480 + (IB * 2%) = $1220

IB * 2% = $1220 - $480

IB * 2% = 740

IB = 740 / 2%

IB = $37,000

Therefor, Jane invested $37,000 in Fund B.

Answer:tff

Step-by-step explanation:

The required medicare tax paid this year is given as $1015.

Given that,
Zachary has a taxable income of $70,000. and paid 1.45 medicare tax,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Medicare tax paid = 70000  × 1.45 / 100
medicare tax paid = $1015

Thus, the required medicare tax paid this year is given as $1015.

Answer:

  p(t) = 5×2^t

Step-by-step explanation:

You are given a couple of points, so can find the values of 'a' and 'b' in the function.

  p(0) = 5

  p(0) = a×b^0 = a

  a = 5

__

  p(1) = 10

  p(1) = 5×b^1

  10 = 5b

  2 = b . . . . divide by 5

__

Now you know the function is ...

  p(t) = 5×2^t
