Solve the following simultaneous linear equations.
2x + y = 5
4x – 3y = -10​

Answers

Answer:

(1/2,4)

Step-by-step explanation:

First, determine y in first equation: 2x+y=5 or  y=5-2x

replace value of y determined in first equation (5-2x) into 2nd equation    

4x-3(5-2x)=-10

4x-15+6x=10

10x=5

x=1/2

put value of x into either equation to solve for y so

2(1/2)+y=5

1+y=5

y=4

answer: x=1/2, y=4

check answer by substituting x and y into either equation:

4x-3y=-10

4(1/2)-3(4)=-10

2-12=-10

-10=-10

or

2x+y=5

2(1/2)+4=5

1+4=5

5=5

What is the area of triangle ABC?

Select the correct choice.

A: 6sqrt3
B: 18sqrt3
C: 36sqrt3
D: 72sqrt3

Answers

Answer:

C

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

The triangle is equilateral , since 3 angles = 60°

Then base AB = 12

Find height CD using the sine ratio in the right triangle ( there are 2 )

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{CD}{BC}[/tex] = [tex]\frac{CD}{12}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ← exact value of sin60° ( cross- multiply )

2CD = 12[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

CD = 6[tex]\sqrt{3}[/tex]

Then

A = [tex]\frac{1}{2}[/tex] × 12 × 6[tex]\sqrt{3}[/tex] = 6 × 6[tex]\sqrt{3}[/tex] = 36[tex]\sqrt{3}[/tex] units² → C

Amy buys 23 envelopes for 16p each and pays with a £5 note. How much change does she get? Give your answer in pounds

Answers

Answer: £1.32

Step-by-step explanation:

Amy buys 23 envelopes and each of them cost 16p.

1p makes a pound so 16 pence is £0.16.

23 envelopes would cost:

= 0.16 * 23

= £3.68

Her change in Pounds would be:

= 5 - 3.68

Answers

Answer:

Future amount = 100(1.9)^5 ;

2476

Step-by-step explanation:

P(t) = P0 * (1 + r)^t

P(t) = 100 * (1 + 90/100)^t#

P(t) = 100 * (1 + 0.9)^t

Therefore, the number of bacteria in 5 years :

P(5) = 100 * (1 + 0.9)^5

P(5) = 100 * (1.9)^5

P(5) = 100 * 24.76099

P(5) = 2476.099

P(5) = 2476 bacteria

Answers

Step-by-step explanation:

b) average velocity : ∆x/∆t = 100/9.8 ≈ 10.204 m/s

c) ∆x = v.∆t = 10.204 × 3 = 30.612 m

Nancy’s gross annual income is $46,905. She is paid monthly and has 9% deducted from her paychecks for her 403(b). Her employer matches her deduction, up to 3%.


How much is deposited into her retirement plan each payday?


Answers:

$234.52


$351.79


$469.05


$703.58

_______________

Thank you in advance!

Answers

Answer:

The amount deposited into her retirement plan each payday is;

$469.05

Step-by-step explanation:

From the details given on Nancy's income, we have;

Nancy's gross annual income = $46,905

The percentage deducted from her monthly paycheck for her 403(b) = 9%

The percentage her employer matches her deductions up to = 3%

Therefore, we have;

Her monthly pay = (Her gross annual income)÷12

∴ Her monthly pay = $46,905÷12 = $3,908.75

The amount deducted from her paycheck, A = 9% of $3,908.75

∴ A = 9/100 × $3,908.75 = $351.7875

The amount her employer matches her deductions up to, B = 3% of $3,908.75

∴ B = 3/100 × $3,908.75 = $117.2625

Therefore;

The amount deposited into her retirement plan each payday, D = A + B

∴ D = $351.7875 + $117.2625 = $469.05

The amount deposited into her retirement plan each payday, D = $469.05.

One of the roots of this equation is twice that of the other. Let the roots are [tex]\alpha \ and\ \beta[/tex], [tex]\alpha =2\beta[/tex]

Sum of roots, [tex]\alpha +\beta =\dfrac{-b}{a}[/tex]
