Answer:
y - 10 = -1/2(x + 4)
General Formulas and Concepts:
<u>Algebra I</u>
Coordinates (x, y)
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>m</em> = -1/2
Point (-4, 10) → x₁ = -4, y₁ = 10
<em />
<u>Step 2: Find</u>
- Substitute in variables [Point-Slope Form]: y - 10 = -1/2(x - -4)
- Simplify: y - 10 = -1/2(x + 4)
I think you cross multiply to get 8x=5y
Answer: 7:35 a. M
Step-by-step explanation:
Given that:
Snooze on alarm = 5 minutes
Snooze on cellphone = 7 minutes
If both activates at 7:00 a. M
Time at which both will activate again ;
Obtain the Lowest Common Multiple of 5 and 7
_5 __|5 ___|7
_7__ |1 ___|7
____ |1 ___| 1
Lowest common multiple = (5 * 7) = 35
Hence, both alarms will sound together again after 35 minutes = 7:00a.m + 35 minutes = 7:35 A. M
Answer:
y = 36.
Step-by-step explanation:
If you think about it, the three angles in the triangle add up to be 180. The missing angle just so happens to be part of a supplementary angle, that adds to be 180. If the unlabeled angle were denoted as x, we could have...
(y + 5) + y + x = 180
y + 41 + x = 180
(y + 5) + y + x = y + 41 + x
(y + 5) + y = y + 41
2y + 5 = y + 41
y = 36
Hope this helps!
Step-by-step explanation:
2x = x1.2^n
2 = 1.2^n
log1.2(2) = n
log10(2)/log10(1.2) = n = 3.801784017...
so, rounded to the next whole year it takes 4 years.
