2(5x+7) + 2(8x-9)
= 10x + 14 + 16x - 18
= 26x - 4
Point slope form is the line through (a,b) with slope m is
y - b = m(x - a)
y - 8 = 5(x - 9)
y - 8 = 5x - 45
y = 5x - 37
Answer: y = 5x - 37
Answer:
5
Step-by-step explanation:
Answer is: 32 nickels and 23 dimes.
<span>x - number of nickels .
y -number of dimes.
two equations in two unknowns:
1) x + y = 55
2) 0,05x + 0,1y = 3,90.
</span>nickel is a five-cent coin.
dime is a ten-cent coin.<span>
solve equation 1) for x and substitute for x in equation 2)
x = 55 - y
0,05</span>·(55 - y) + 0,1y = 3,90<span>2,75 - 0,05y + 0,1y = 3,90
0,05y = 1,15
y = 23.
x = 55 - 23 = 32.</span>
