Solve the following system of equations graphically on the set of axes below
Answers
The solution is the point where the two lines intersect i.e. (-1,-7). The graph for the given system of equations is attached below wherein the blue line represents y=2x-5 and the green line represents y=-x-8.
What is system of equation?
A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and visual solutions are possible for these equations. The intersection of two lines represents the system of equations' solution.
For solving the equations graphically, we need to find points for plotting
So, for y = 2x-5,
The y-intercept is -5, so we need to place a point on the graph at (0,-5). For the another point, put x=1, we get y= -3. So we need to place another point at (1,-3).
Similarly for y = -x-8,
The y-intercept is -8, so we need to place a point on the graph at (0,-8). For the another point, put x=1, we get y= -9. So we need to place another point at (1,-9).
The solution is the point where the two lines intersect.
When the two lines intersect,
2x-5=-x-8
3x=-3
x=-1
So, y=-7
Hence, the two lines intersect at (-1,-7).

You (or your parents) are debating about whether to buy a new car for $19,072.00 or a used car for $15,635.00. Sales tax is 4.5%. You (or your parents) plan to make a down payment of $1,200.00 and your credit rating is fair. Use the table below to determine the difference in interest accrued by the end of the first month.
Secured Unsecured
Credit APR (%) APR (%)
Excellent 5.4 5.65
Good 5.95 6.35
Average 6.30 6.90
Fair 7.55 7.60
Poor 9.80 10.0
Answers
Answer: $20.95
Due to credit rating being fair:
Secured APR = 7.00%
Loan amount = sale price + tax - down payment
New car = [tex]19027 + (19072 x 0.045) - 1200 = 18730.24[/tex]
Used car = [tex]15635 + (15635 x 0.045) - 1200 = 15138.575[/tex]
---------------------------------------------------------------------------
Monthly interest = loan amount [tex]x 0.07 x 1/12[/tex]
New car = [tex]18730.24 x 0.07 x 1/12 = 109.26[/tex]
Used car = [tex]15138.575 x 0.07 x 1/12 = 88.31[/tex]
Thus, the difference is [tex]109.26 - 88.31 = $20.95[/tex]
An art museum installed a large triangular sculpture. One of the sculpture’s exterior angles creates a 158 angle with the ground.
If the sculpture’s opposite interior angle is 32 less than the interior non-adjacent angle, what is the measure of the interior non-adjacent angle?
Answers
The measure of the interior non-adjacent angle as required in the task content is; 95°.
What is the measure of the interior non-adjacent angle?Recall; It follows from the triangle exterior angle theorem that the measure of exterior angle of a triangle is equal to the sum of the two opposite interiors angles.
On this note, if the sculpture’s opposite interior angle is 32 less than the interior non-adjacent angle, the sum of the two angle measures is therefore;
x + x - 32.
where, x is the measure of the interior non-adjacent angle.
Hence, x + x - 32 = 158
2x = 158 + 32
2x = 190
x = 95°.
Ultimately, the measure of the interior non-adjacent angle is; 95°.

Joyce has $13 in savings and saves an additional $6 each week. At the same time, Enrique has $80 in savings and spends $5 each week to go swimming at the community pool. Is there a week when Joyce and Enrique will have the same amount of money? Explain why or why not.
Answers
Answer: Yes, after 7 weeks, they will have the same amount of money
Step-by-step explanation: So let’s say Joyce will be equation 1, so it would be - T = 13 + 6x, where T represents the total money, and x represents the number of weeks. And let’s say Enrique will be equation 2, which will be - T = 80 - 5x, where once again, T represents the total money, and x represents the number of weeks.
So, let’s start going off numbers, we will start at 5 weeks, when we put that in, Joyce will have $43 and Enrique will have $65, so we know it will be more than 5 weeks, so let’s try 8 weeks, Joyce will have $61 and Enrique will have $40, so it’s below 8, so how about we try 7, at 7 weeks, Joyce will have $55, and Enrique will have $55 too. So this means, after 7 weeks, Joyce and Enrique will have the same amount of money
If a "2" is rolled on a fair 6-
sided die, what event is most

A. a roll lower than 2
B. a roll higher than 2
C. another 2
D. all of these events are equally

Answers
The event with the largest probability is rolling a number higher than 2, so the correct option is B.
Which event is most likely to occur next?First, the fact that a 2 was rolled before does not affect the next rolls of the dice, so that information is extra.
Now we just need to see which option has the largest probability.
A) There are only one number lower than 2, then the probability of this event is p = 1/6
B) There are 3 numbers higher than 2, then the probability is p = 3/6 = 1/2
C) The probability of get another 2 is 1/6
We can see that the event with the largest probability is B, so that one is the most likely to occur.

Can be seen in the image below.
Which graph correctly represents the inequality?We want to see which graph represents the inequality:
3x + y > 7
We can rewrite the inequality in slope-intercept form as:
y > -3x + 7
So we just need to graph the line:
y = -3x + 7
With a dashed line, and then shade all the region above the line.
To graph the line, you need to find two points that lie on the line.
if we evaluate the line in x = 0 we wll get:
y = -3*0 + 7
y = 7
if x = 1
y = -3*1 + 7
y = -4
Then we have the points (0, -7) and (1, -4), now we can graph these two points and connect them with a dashed line, then shade the region above.

As per the following diagram, the angle measures of triangle EFC is 118°
The term angle in math is known as a figure which is formed by two rays or lines that shares a common endpoint.

Thus implies that the angles,
=> ∠DFB = ∠FEB = 31°
Then the value of the angle is calculated as,
=> ∠EDB =∠EFB = 90° - 31°
=> ∠EDB = ∠EFB = 59°
Then the value of the angle ABC is calculated by sum the values of the angles, then we get,

Answers
Acute angles are the angles that measure less than 90 degrees. Right angles measure 90 degrees and Obtuse angles measure more than 90 degrees.
How to explain the angles!By adding the squares of the triangle's two smaller sides and comparing the result to the square of the largest side, you can determine whether the triangle is acute, right, or obtuse. The triangle is acute because this sum is higher.
A triangle is said to be acute if the squares of its two shorter sides added together exceed those of its longest side. A triangle is considered obtuse if the sum of the squares of its two shorter sides is less than the square of its longest side.

Ian wants to ride his bicycle 36.5 miles this week he has already written 8 miles if he rides for five more days which equation could be used to determine M the average number of miles he would have to ride to meet his goal?
Answers
Answer:
M = (36.5-8)/5
[M = 5.7 miles/day]
Step-by-step explanation:
The goal is 36.5 miles. The remaining miles needed to achieve this goal is reduced by the miles already ridden, 8 miles.
(36.5 - 8) = 28.5 miles remaining.
We are asked to find a value for M, which is the average number of miles Ian would have to ride to reach his goal. By average, we can assume it is the average miles/days remaining. The days remaining are 5, so we have:
(28.5 miles remaining)/5 days = 5.7 miles/day
An equation for M using these steps would be:
M = (36.5-8)/5

Answers
The replacement or substitution approach has the advantage of providing the precise values for the variables (x and y), which correspond to the site of intersection.
The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the second equation in this procedure, as the name implies.
This makes it easier to solve by combining two linear equations into one equation with a single variable. Learn about the graphical approach and the algebraic method before beginning to solve the linear equations using the substitution method.
By changing the value of another variable in an equation, the variable can be eliminated. Thus, the elimination by substitution method is the name given to this technique.
