Answer: D)

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

1750 − 250x = 1000.

So, in this expression $1750 is the amount of money that the Russell family started with, and 250 is the cost of each day on vacation.

Since the cost of each day is multiplied by a variable, the variable "x" is the number of days that the Russell’s have been on vacation.

1000 is the money left to spend.

Option d)

Question 24 Multiple Choice Worth 1 points)
hammer [34]

Given:

The system of equations is:

Line A: y=x-4

Line B: y=3x+4

To find:

The solution of given system of equations.

Solution:

We have,

y=x-4              ...(i)

y=3x+4           ...(ii)

Equating (i) and (ii), we get

x-4=3x+4

-4-4=3x-x

-8=2x

Divide both sides by 2.

-4=x

Substituting x=-4 in (i), we get

y=-4-4

y=-8

The solution of system of equations is (-4,-8).

Now verify the solution by substituting x=-4, y=-8 in the given equations.

-8=-4-4

-8=-8

This statement is true.

Similarly,

-8=3(-4)+4

-8=-12+4

-8=-8

This statement is also true.

Therefore, (-4,-8) is a solution of the given system of equations, because the point satisfies both equations. Hence, the correct option is C.

Solve the system and enter the smallest x-coordinate first
ankoles [38]
Answer:
(2,-3)(6,5)
Step-by-step explanation:
We can use substitution to get the equation: x^2-6x+5 = 2x-7
Solve:
x^2-6x+5 = 2x-7
x^2 = 8x-12
x^2-8x+12 = 0 (we now have a polynomial)
(x-6)(x-2) = 0 (set each equation to equal 0 and solve)
x-6 = 0 --> x=6
x-2 = 0 --> x=2
To get the Y coordinates:
y=2(2)-7 --> y = -3
y = 2(6)-7 --> y = 5

Check work:
5 = 6^2-6(6)+5 --> 5 = 36-36 +5 --> 5=5
-3 = 2^2-6(2)+5 --> -3 = 4-12+5 --> -3=-3

Samuel has an auto insurance policy that covers theft up to $15,000, with a $250 deductible. His car is worth $8,000. What will
Yanka [14]

Answer:A

Step-by-step explanation:

If the auto insurance covers theft up to $15,000 and his car value is less than it ($8,000), he is going to pay only $250 deductible. It means that it covers values until $15,000.
