Answer:

12 years old

Step-by-step explanation:

m = Michael

a = Margaret

m = 3a

m+6 = 2(a+6)

m+6 = 2a+12

Two equations, two unknowns, so we can use substitution.

3a+6 = 2a+12

a+6 = 12

a = 6

Plug it back in.

m = 3(6)

m = 18

When Michael was 18, Margaret was 6. So when she was born (basically when she was 0) Michael was 18-6 = 12.

Answer:

6  1 / 24

Step-by-step explanation:

in 1 hour - 5 / 6 tons of dust

Total dust = 7  1 / 4 = 29 / 4

1 ----- 5 / 6

x ----- 29 / 4

x = (29 / 4 ) * (5 / 6)

x = 145 / 24

x = 6  1 / 24

Help! graph Y - 2 = -3/4 (X-6). please use the graph I provided
Fiesta28 [93]

A graph of this equation y - 2 = -3/4(x - 6) is shown in the image attached below.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that is typically used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate.

Next, we would rearrange and simplify the given given equation in slope-intercept form in order to enable us plot it on a graph:

y - 2 = -3/4(x - 6)

Opening the bracket, we have:

y - 2 = -3x/4 + 18/4

y = -3x/4 + 18/4 + 2

y = -3x/4 - 26/4

y = -3x/4 - 13/2

Therefore, the slope is equal to -3/4 and the y-intercept is equal to -13/2.

In conclusion, we can logically deduce that the graph representing the given linear equation does not show a proportional relationship between the value of x and y.

Evaluate the line integral, where C is the given curve. (x + 4y) dx + x2 dy, C C consists of line segments from (0, 0) to (4, 1)
zubka84 [21]

Parameterize the line segments (call them C_1 and C_2, respectively, by

\vec r_1(t)=(1-t)(0,0)+t(4,1)=(4t,t)

\vec r_2(t)=(1-t)(4,1)+t(5,0)=(4+t,1-t)

both with 0\le t\le1. Then

\displaystyle\int_C(x+4y)\,\mathrm dx+x^2\,\mathrm dy

=\displaystyle\int_0^1\bigg((4t+4t)(4)+(4t)^2(1)\bigg)\,\mathrm dt+\int_0^1\bigg((4+t+4(1-t))(1)+(4+t)^2(-1)\bigg)\,\mathrm dt

=\displaystyle\int_0^115t^2+21t-8\,\mathrm dt=\boxed{\frac{15}2}
