Answer:
Step-by-step explanation:
(-5 + 2)/(2 - 0)= -3/2
y + 2 = -3/2(x - 0)
y + 2 = -3/2x + 0
y = -3/2x - 2
Answer:
$90
Step-by-step explanation:
Let B represent bracelets and N represent necklaces
4B + 6N = $66
6B + 3N = $45 mutyply second equation by -2
-2 × (6B + 3N) = $45 ➡ -12B - 6N = -$90 now add this to the first equation
4B + 6N -12B - 6N = $66 - $90 add the like terms (-6N will eliminate 6N)
-8B = -$24 ➡8B = $24 ➡ B = $3
one bracelet costs $3 ww can find the price of necklace by using this information
6B + 3N = $45 write $3 instead of B
6× $3 + 3N = $45
$24 + 3N = $45
3N = $45
N = $15 this is the price for a necklace
For five bracelets and five necklaces the cost would be 5 × $15 + 5 × $3 = $90
Answer:A=8x^2 + 20x - 100
Step-by-step explanation:
The area of rectangle is:
A= length × width
A= (2x+10)(4x-10)
So now expand the bracket8
A=8x^2 - 20x + 40x - 100
A=8x^2 + 20x - 100
