Answer:
y =-5x-17
Step-by-step explanation:
Slode-intercept is
y = mx + c
The first step is to find the slope, that is the m
To do that, use this formula
Y2 - y1
------------
X2- x1
And u will get - 5
Now since u got m, u also actually have y and x, those are the coordinates they gave u. U can choose either one,(-3, - 2) or (-4, 3), cuz they would give u the same answrs
So let's say I chose (-4, 3)
So x = - 4, y = 3
y=mx +c
3= - 5(-4) +c
C = - 17
Therefore your end product will be
y = - 5x - 17
Answer:
f. sqrt 7 meters
Step-by-step explanation:
we use Pythagoras' theorem here,
let the unknown side be x,
therefore,
=> 3² + x² = 4²
=> x² = 16 - 9
=> x = √7 m
3/2x - 4 = 16
Add 4 to both sides.
3/2x = 20
Multiply by 2/3.
x = 13 1/3
Answer:
Solution:
Given, cost price = $784.50
Profit = 6.5% of cost price
= 6.5/100 × $784.50
= $50.9925 [since, profit% is always on C.P.]
And selling price = cost price + profit
= $784.50 + $50.9925
= $835.4925
Hence, selling price = $835.4925
