yarga [219]3 years ago
7 0

Answer:

<em>x = 12 </em>

Step-by-step explanation:

(x + 42)° + 3x° = 90°

x + 3x + 42 = 90

4x = 90 - 42

4x = 48

<em>x = 12</em>

Find a point-slope form for the line with slope 1/5<br> and passing through the point (-7,-4).
Basile [38]

Answer:

y + 4 = ⅕(x + 7)  

Step-by-step explanation:

The "point-slope" form of the equation of a straight line is:

y − y₁ = m(x − x₁)

where m is the slope and (x₁, y₁) is a point on the line.

If m = ⅕ and (x₁, y₁) = (-7,  - 4), the point-slope equation is

y + 4 = ⅕(x + 7)

The Figure below shows the graph of your line and a point at (-7, -4).

Round 538.060 to the nearest whole number
sasho [114]

Answer:

538

Step-by-step explanation:

if you round the hundreth place up, the tenth place would be 1. However, rounding that would give you 0 as it's less than 5. Therefore, all decimal places would become 0, and that only leaves 538.
