Answer:
Step-by-step explanation:
Lupita brought seven pounds of pretzels at a local wholesaler for 16.80. This means that the rate at which she bought one pound of pretzel at the local wholesaler would be
16.80 / 7 = $2.4 per pounds of pretzels
Her friend, Charles about 5 pounds of pretzels at the supermarket 12.75. This means that the rate at which Charles bought one pound of pretzel at the supermarket would be
12.75 / 5 = $2.55 per pounds of pretzels
Charles's reasoning is wrong because the rate at which he bought one pound of pretzel is higher than that of Lupita's
Answer:
Here,
slope (m)=-2
y- intercept (c)=-7
Now,
The equation of the line;
or,y=mx+c
or,y= -2x-7
or,2x+y+7=0 is the required equation....
The angles of a triangle will always add up to be 180 degrees total.
x + 82 + x + 82 + 40 = 180
2x + 164 + 40 = 180
2x + 204 = 180
Subtract 204 from both sides.
Think of it as “180 + (-204)”
2x = -24
Divide each side by 2.
x = -12
Answer: x = -12
Slope= y^2-y^1
————
x^2-x^1
slope= 12-0
——-
6+2
slope= 12
—-
8
slope= 3/2
perpendicular slope is the opposite reciprocal
perpendicular slope= -2/3
I would think miles per hour would be the best units to use because that is what the speedometer of a car is read in. Hope this helped! comment back with any questions you still have!
