Answer:
y - 4 = 5(x - 7) or y = 5x - 31
Step-by-step explanation:
Slope-intercept form: <em>y = mx + b</em> (m = slope, b = y-intercept)
Point-slope form: <em>y - y₁ = m(x - x₁)</em> ((x₁, y₁) = known point, m = slope)
1. Slope: perpendicular to -1/5 --> 5 (negative reciprocal)
2. Insert knowns into equation: y - 4 = 5(x - 7)
3. Turn into point-slope form (assuming that is what we are looking for):
Multiply: <em>y - 4 = 5x - 35</em>
Subtract: y = 5x - 31

Answer:
$95
Step-by-step explanation:
I you need to see how much you would save after 7 weeks, and you save $10 a week, that would be 7*$10 and if you start with $25 you add it.
$25 + 7*($10) =
$25 + $70 = $95
After 7 weeks you would have saved $95.
If you need to know your savings each week, start with $25, and add $10 to it each week.
$25
Week 1 - $25 + 10 = $35
Week 2 - $35 + 10 = $45
Week 3 - $45 + 10 = $55
Week 4 - $55 + 10 = $65
Week 5 - $65 + 10 = $75
Week 6 - $75 + 10 = $85
Week 7 - $85 + 10 = $95
Answer:
−27a^(15)
Step-by-step explanation:
Answer:
since you are trying to get the scaled copy smaller you need to instead of multiply by 7 multiply by 1/7
