Answer:
No.
Step-by-step explanation:
If they do intersect, the measurement of the angles they form is a half the difference of the intercepted arcs; both of the intercepted arcs would measure 180 degrees.
Answer:
No
Step-by-step explanation:
When you distribute the -2 you get 6x -2x+2. When you simplify it you get 4x+2 which is different than 4x-2.
Answer:
<h2>14mph</h2>
Step-by-step explanation:
Given the gas mileage for a certain vehicle modeled by the equation m=−0.05x²+3.5x−49 where x is the speed of the vehicle in mph. In order to determine the speed(s) at which the car gets 9 mpg, we will substitute the value of m = 9 into the modeled equation and calculate x as shown;
m = −0.05x²+3.5x−49
when m= 9
9 = −0.05x²+3.5x−49
−0.05x²+3.5x−49 = 9
0.05x²-3.5x+49 = -9
Multiplying through by 100
5x²+350x−4900 = 900
Dividing through by 5;
x²+70x−980 = 180
x²+70x−980 - 180 = 0
x²+70x−1160 = 0
Using the general formula to get x;
a = 1, b = 70, c = -1160
x = -70±√70²-4(1)(-1160)/2
x = -70±√4900+4640)/2
x = -70±(√4900+4640)/2
x = -70±√9540/2
x = -70±97.7/2
x = -70+97.7/2
x = 27.7/2
x = 13.85mph
x ≈ 14 mph
Hence, the speed(s) at which the car gets 9 mpg to the nearest mph is 14mph
Answer: x = 11
Explanation: if u want more math questions just ask me ok
Given:
Budget for tiles = 1,200
number of white tiles = 38
unit cost of white tiles = 12
budget for brown tiles = x
cost of white tiles = 38 x 12 = 456
The inequality would be:
Cost of brown tiles + cost of white tiles <u><</u> budget
x + 456 <u><</u> 1,200
solving the inequality:
x + 456 <u><</u> 1,200
<u> - 456 -456</u>
x <u><</u> 744
Mr. Jacobs can spend up to 744 for the brown tiles.
