I need help plss!! Thankyou in advance!!

The sum of Bill's age and
Nancy's age is 45. In three years, bill will be three times as old as Nancy
was four years ago. Create a system of linear equations to represent the relationship between
Bill's age and Nancy's age. Solve the system graphically to determine how old Bill and Nancy are
today?

Answer:

correct value of x = 5

Step-by-step explanation:

[tex] \frac{ {( - 2)}^{4x + 2} }{ {( - 2)}^{2x} } = {( - 2)}^{12} \\ = \frac{ {( - 2)}^{4 \times 5 + 2} }{ { ( - 2)}^{2 \times 5 } } \\ = \frac{ {( - 2)}^{22} }{ { ( - 2)}^{10} } \\ = \frac{4194304}{1024} \\ = 4096 = 4096(i.e \: {( - 12)}^{12} = 4096) \\ [/tex]

Given:

Principal = $50

Rate of simple interest = 6%

Time = 3 years

To find:

The amount after 3 years.

Solution:

Formula for simple interest:

[tex]I=\dfrac{P\times r\times t}{100}[/tex]

Where, P is principal, r is the rate of interest in percentage and t is the number of years.

Putting [tex]P=50,\ r=6,\ t=3[/tex] in the above formula, we get

[tex]I=\dfrac{50\times 6\times 3}{100}[/tex]

[tex]I=\dfrac{900}{100}[/tex]

[tex]I=9[/tex]

Formula for amount is:

[tex]A=P+I[/tex]

Where, P is principal and I is the simple interest.

Putting [tex]P=50,\ I=9[/tex], we get

[tex]A=50+9[/tex]

[tex]A=59[/tex]

Therefore, the correct option is B.

Answer:

$1,952

Step-by-step explanation:

1.25 * 156,215/100

=1,952

When we have negative exponents, we can move the term with the exponent to the bottom of the fraction. This is also known as multiplying by the reciprocal (and changing the negative exponent to be positive!).

The reciprocal of z^-3 would be 1 / z^3.

Hope this helps!! :)

Answer:

y = x - 4

Step-by-step explanation:

Given:

Passes through (6, 2)

m = 1

Slope-intercept:

y - y1 = m(x - x1)

y - 2 = 1(x - 6)

y - 2 = x - 6

y = x - 4

Answer:

portion = 85.50

Step-by-step explanation:

[tex]Rate = (\frac{Portion}{Base})*100%[/tex]

Rate = 19%, Base = 450

[tex]19 = \frac{portion}{450} \times 100\\\\19 \times 450 = portion \times 100\\\\\frac{8550}{100} = portion \\\\portion = 85.50[/tex]

Answer:

16 ft.

Step-by-step explanation:

Distance Formula:

A = (2,2)

B = (12,14)

So, sqrt(12^2 + 10^2) = 16 ft.

This is the same for B to C.

So, 16 ft.

Answer:

20

Step-by-step explanation:

20 - 9 = 11

I hope this helps

Answer:

20

Step-by-step explanation:

Call the number you're trying to find  n.

"What" becomes  n.

n - 9 = 11

To "undo" the subtraction and reveal the value of  n ,  ADD 9 to both sides of the equation.  (Addition is the inverse operation of subtraction.)

n = 11 + 9 = 20

Answer:

-13x+5

Step-by-step explanation:

Distributive Property

-4 (2.5x) + (-4)(-1.25) - 3x

Multiply 2.5 by -4

- 10x - 4 * 1.25 - 3x

Multiply -4 by 1.25

- 10x + 5 -3x

Subtract 3x from -10x

-13x + 5

The length of the hypotenuse in a right triangle is 12 inches.

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Given that, the lengths of the legs of a right triangle are 8 inches and 9 inches.

Let the length of the hypotenuse be x.

Here, x²=8²+9²

x²=64+81

x²=145

x=√145

x=12.04

x≈12 inches

Therefore, the length of the hypotenuse is 12 inches.

Answer:

X + 9 = 21

Isolate the variable, meaning getting rid of the constants

-9         -9

X = 12

Answer:

12

Step-by-step explanation:

To get the answer 12 you must:

Subtract 21 - 9

That would get you your answer.

Answer:

Step-by-step explanation:

take angle A as reference angle

using cos rule

cos A=adjacent/hypotenuse

cos A=12/13

cos A=0.92

A=cos 23

A=23 degree

for ratio,

cos A=12/13

Cos( A ) = AC / AB [ Ratio ]

Cos( A ) = 12 / 13 [ Ratio ]

Cos( A ) = 0. 92307 [ Exact value ]

Answer:

y = -4

Step-by-step explanation:

When y is directly proportional to x,

= y ∝ x

= y = kx

Finding k

the value of y = -2 when x = 4

-2 = k4

k = -2/4

k = -1/2

. What is the value of y when x = 8

Finding y

y = kx

y = -1/2 × 8

y = -4
