Answer:x= -4 and -6
Step-by-step explanation:
To solve the equation x²+10x+24=0, we need to factorize. Factorizing this using the general formula,
x = -b+/-√b²-4ac/2a
Generally, quadratic equation are of the form ax²+bx+c=0
Comparing the coefficients;
a= 1, b=10 and c=24
Substituting this into the general formula,
x = -10+/-√10²-4(1)(24)/2(1)
x = -10 +/-√100-96/2
x = -10 +/-√4/2
x = -10 +/- 2/2
x = -10 + 2/2 and -10-2/2
x = -8/2 and -12/2
x = -4 and -6

Time to complete the distance ( walk time ) ≈ 10 minutes
Hi your question is incomplete but I will provide the general principles on how to resolve this kind of problems
The variables to be considered are :
To determine how long a five minute drive would take a walk to complete
first step : determine the distance
speed = distance / time
assume distance = x
speed = x/5
second step : assume speed of car
lets assume the speed of the car = 20 m/minutes
20 = x / 5
therefore x ( distance ) = 20 * 5 = 100 meters
assume walking speed = 10 m/minutes
y ( time to complete distance ) = distance / speed = 100 / 10 = 10 minutes
Hence based on my assumptions walk time = 10 minutes

Step-by-step explanation:
Bret paid $12 as sales tax.
A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In a fraction say (x/y), [y] is called denominator.
We have Bret buys a dining table that costs $150 before tax. The sales tax is 8%.
Assume that he paid $[x] as sales tax. Then, we can write -
[x] = 8% of 150
[x] = (8/100) x 150
[x] = 12
Therefore, Bret paid $12 as sales tax.

Answer:
$12
Step-by-step explanation:
to find sales tax you multiply the cost by the percentage
you do 150 * 8%
thats also 150 * 0.08
150 * 0.08 is 12
so you pay $12 in tax
Answer:
Column A: Domain: B: -6, -3, -2, 0, 2, 3, 5, 8
Column A: Range: A: -2, -1, 9, 2, 3
Step-by-step explanation:
We can derive these answers by looking at the x and y values of each dot. The Domain is represented by the x values, and the Range is represented by the y values.
The answers chosen contain the x and y values that the graph represents.
