Think about the system associated with the equation –x2 + x + 6 = 2x + 8. Which graph represents the system?

Answers

Answer 1

Answer:

Step-by-step explanation:

Set each equation equal to y, then graph each equation.

y = -x² + x + 6 (parabola)

y = 2x + 8 (line)

Notice that the system has NO SOLUTION because the parabola and the line never intersect.

Solve for x by answering the number below/

Answers

X = 5.

2(5)+8=4(5)-2
18=18

Answer:

The value of x is 5.

Step-by-step explanation:

In a square, all sides are equal so you can compare the expressions to solve x :

[tex]4x - 2 = 2x + 8[/tex]

[tex]4x - 2x = 8 + 2[/tex]

[tex]2x = 10[/tex]

A barrel contained 70 gallons of water. Water leaked out of the barrel at a rate of 5 gallons every 3 days.

At this rate, how many days did it take for all 70 gallons of water to leak out of the barrel?

Answers

Answer:

42 days

Step-by-step explanation:

Given

[tex]Gallons = 70[/tex]

Leakage = 5 gallons in 3 days

Required

Determine the number of days it finish leaking out

The scenario can be represented as:

5 gallons = 3 days

and

70 gallons = x

Where x represents the number of days to leak out 70 gallons

Cross Multiply:

[tex]5 * x = 3 * 70[/tex]

[tex]5 x = 210[/tex]

Divide both sides by 5

[tex]x = \frac{210}{5}[/tex]

[tex]x = 42[/tex]

Hence, it'll take 42 days

How does a straight line represents the proportionality ratio?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written to express proportional relationship as -

y = kx {k is constant}

We have Jean is [x] years old and Jonathan is [y] years old

Assume that Jonathon is [m] years older than Jean. Then we can write -

y = mx

m = y/x

Therefore, Jonathon is [y/x] years older than Jean.

Answers

Complete question is;

A family of 6 is visiting a mall. The mall has 10 exit doors. Assume random selection. Find the probability that

a. No family member chooses the same exit door.

b. Every family member chooses the same exit door.

Answer:

A) 0.6

B) 0.1

Step-by-step explanation:

A) We are told there are 10 exit doors and the family consists of 6 people.

This implies that for them not to choose the same exit door there will be 6 different doors they will pass.

Thus;

Probability that the no family member chooses the same exit door = 6/10 = 0.6

B) If they all choose the same exit door, it means only 1 out of the 10 exit doors will be used by them.

Thus;

Probability that every family member chooses the same exit door = 1/10 = 0.1
