Which equation best represents the graph?
Answer:
The third one
Step-by-step explanation:
The graphs in the reversed shape of a cup are the graphs of quadratic equations whose coefficient of
x^2 is negative.
So, the answer must be either the first or the third.
It can be seen that when x= -4, y becomes 5.
Substituting the value of x, the third equation gives the value 5.
So, the answer is the third one.

The square of a number x is 16 more than six times the number
Form an equation in x and solve it.
Answer:
x= 8
Step-by-step explanation:
x^2 = 6x+16
TAKE RHS OVER TO LHS TO EQUATE IT TO 0
x^2 - 6x - 16 = 0
FACTORISE
(x-8)(x+2) =0
Therefore
x-8= 0 or x+2= 0
x= 8 or x= - 2
Sub and see which works
8^2 = 6(8) + 16
64= 64
-2^2 = 6(-2) + 16
-4= 4
So the answer must be
x= 8

A car and a truck left Washington, DC traveling in opposite directions. The car
traveled 19 miles
per hour faster than the truck, and at the end of 8 hours they were
1048 miles apart. What was the average speed of each vehicle?
Answer:
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Step-by-step explanation:
Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.
car = ( x + 19 ) mph
truck = ( x ) mph
Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:
(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )
Substitute,
( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048
Simplify,
8x + 152 + 8x = 1048
16x + 152 = 1048
-152 -152
16x = 896
/16 /16
x = 56
Add (19) to find the speed of the car:
truck speed + 19
= 56 + 19
= 75
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Answer:
The truck traveled at 81
mph. The car traveled at 100
mph.
Step-by-step explanation:
Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26 By what percentage has Rebecca's car insurance been reduced?
Answer:
Step-by-step explanation:
Rebecca's car insurance been reduced by 18%
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26.
Percentage decrease = (Final value - initial value) / initial value × 100
Final value = £1675.26
Initial value = £2043
Percentage decrease = (2043 - 1675.26) / 2043 × 100
= 367.74 / 2043 × 100
= 0.18 × 100
= 18 %
Hence, Rebecca's car insurance been reduced by 18%
