The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true. For equations having one unknown, raised to a single power, two fundamental rules of algebra, including the additive property and the multiplicative property, are used to determine its solutions.

Which equation describes a line parallel<br> to y= 4x+ 5 through point (-2, 1)?

Tema [17]

Hi there!

For a line to be PARALLEL, it must contain the same slope.

The given line has a slope of 4, so we can use the point-slope formula to solve:

$\large\boxed{y - y_1 = m(x - x_1)}$

y1 = y-coordinate of given point

x1 = x-coordinate of given point

m = slope

Plug in the values:

$y - 1 = 4(x - (-2))\\\\y - 1 = 4(x + 2)$

Simplify:

$y - 1 = 4x + 8\\\\\boxed{y = 4x + 9}$

Emily practices piano for 2/3 of an hour on Monday and 1/2 hour on Wednesdays. How many hours does Emily spend practicing piano

Sergeu [11.5K]

Answer:

50 minutes

Step-by-step explanation:

Given:

$\bullet \ \ \text{Monday:} \ \dfrac{2}{3} \times \text{Hour}\\\\\bullet \ \text{Wednesday:} \ \dfrac{1}{2} \times \text{Hour}$

Since Emily only practiced on Monday and Wednesday, the sum of time on both days is the time Emily practiced on the piano for a week.

$\implies \text{Monday + Wednesday = Total time practiced on piano for a week}$

<u>Substitute the times in the equation</u>

$\implies (\dfrac{2}{3} \times \text{Hour}) + (\dfrac{1}{2} \times \text{Hour}) = \text{Total time practiced on piano for a week}$

<u>Simplify the equation</u>

$\implies (\dfrac{2}{3} \times 60 \ \text{minutes}) + (\dfrac{1}{2} \times 60 \ \text{minutes}) = \text{Total time practiced on piano for a week}$

$\implies (20 \ \text{minutes}) + (30 \ \text{minutes}) = \text{Total time practiced on piano for a week}$

$\implies \boxed{50 \ \text{minutes} = \text{Total time practiced on piano for a week}}$

Convert the angle to a decimal in degrees <br> 60 degree 19 ‘39”

7nadin3 [17]

bearing in mind that there are 60 minutes in 1 degree, and 60 seconds in 1 minute.

60°19'39"

so 39 seconds is really 39/60 minutes, or 0.65 minutes

so 19'39" is really 19.65'.

since there are 60 minutes in 1 degree, then 19.65' is really 19.65/60 degrees, or 0.3275°.

60°19'39" is then 60.3275°.
