The origin is at the point (0,0). Therefore, the y-intercept will be 0. For two points to be perpendicular, the slopes must be opposite reciprocals of each other. .5 can be seen as 1/2, so the reciprocal is 2, and it is positive, making that 2 negative. Your equation would be y = -2x.
Subtract all the operating expenses from the amount he spent total and get what's left over is $491. That's what he spent on gas. Divide the number of miles he drove by the amount he spent on the gas to find out what the average cost of the gas was per mile. 491/7270 = .06753. But that is expressed in dollars and we need it in cents. Multiply that decimal by 100 to get 6.75 cents, choice A from above.
Answer:
2 seed packets.
Step-by-step explanation:
19 plants per seed packet.
19+19=38 + 7=45
The partial products are: 42 x 28 = (40 + 2) x (20 + 8) = 40 x 20 + 40 x 8 + 2 x 20 + 2 x 8
= 800 + 320 + 40 + 16 Hope this helped.
Standard form of a quadratic f(x) = ax^2 + bx + c
In a quadratic function you find the vertex using the formula x = -b/2a; once you find the x value, substitute it into the equation and solve for y.
To know if a parabola opens up or down you look at the coefficient of the x^2 term. If it is positive, the graph opens up; if it is negative, the graph opens down.
