Answer: <em>1</em>
Step-by-step explanation:
<em>The slope of a line perpendicular to x+y=5 is 1</em>
b= 8
Step-by-step explanation:
If we rewrite the 2nd equation, it becomes
15y = -6x - 11 ---> y = (-2/5)x - (11/15)
In order for this system of equations to have no solution, they must have the same slope, i.e., they're parallel to each other. So rewriting the 1st equation,
20y = -bx + 11
---> -b/20 = -0.4 or b = 8
Answer:
A rate is a comparison, or ratio, of two quantities with different units. For example, a store sells
3 T-shirts for $15. The comparison $15 to 3 T-shirts is a rate. This rate can also be written as $15 _______
3 T-shirts.
When a rate compares a quantity to one unit of another quantity, the rate is a unit rate.
The rate $15 _______
3 T-shirts is not a unit rate because the rate compares the cost to more than one T-shirt. In a unit
rate, the second quantity (or denominator) should be 1 unit.
A speed limit is a unit rate. For example, the speed limit of 55 miles per hour compares the distance to
1 hour. A speed of 55 miles per hour is equivalent to traveling 55 miles in each 1-hour time span. This rate can also be written as 55 miles/1 hour
