Which graph shows the solution to Sylvie’s system of equations?
A coordinate grid with 2 lines. The first line passes through the points (negative 1.7, 1.57), (0, negative 1), and (2, negative 4). The second line passes through the points (negative 1.7, 1.57), (0, 1), and (3, 0).
A coordinate grid with 2 lines. The first line passes through the points (negative 1.02, 0.63), (0, negative 1), and (2, negative 4). The second line passes through the points (negative 1.02, 0.63), (0, 1), and (3, 2).
A coordinate grid with 2 lines. The first line passes through the points (negative 1.5, 0), (0, negative 1), and (3, negative 3). The second line passes through the points (negative 1.5, 0), (0, 1), and (3, 3).
The graph that shows the solution to the system of equations is attached below.
How to Find the Solution a System of Linear Equations?The solution to a system of linear equations is the point where the two graphs intersect. The coordinates of that point is the solution.
Given the system as:
y = 2/3x + 1
y = -2/3x - 1
Add both together to eliminate x
2y = 0
y = 0
Substitute y = 0 into y = 2/3x + 1 to find x
0 = 2/3x + 1
-1 = 2/3x
-3 = 2x
-3/2 = x
x = -3/2
The solution is: (-3/2, 0) = (-1.5, 0).
Therefore, the graph that shows the solution will intersect at (-1.5, 0), which is shown in the image attached below.

Cαlligrαρɦγ75 out of 300 oranges in a basket are bad. what percent age of the oranges are (a) bad (b)good
Answer:
a) 25% are bad
b) 75% are good
Step-by-step explanation:
We know that there are 300 oranges total and that 75 are bad. That means that the rest are good (implied).
300 - 75 = 225 good oranges.
So to find the percentage we have to take the selected amount divided by the total amount.
Bad Apples: Good Apples:
75 / 300 = 0.25 225/300 = 0.75
However, that's a decimal or a number out of 1, we need a percent or a number out of 100. So we have to multiply both numbers by 100.
Bad Apples = 25%
Good Apples = 75%
Determine two pairs of polar coordinates for (3,-3) when 0
The two pairs of polar coordinates for the given point (3, -3) with 0° ≤ θ < 360° are (3√2, 135°) and (3√2, 315°).
What is a polar coordinate?A polar coordinate is a two-dimensional coordinate system, wherein each point on a plane is typically determined by a distance (r) from the pole (origin) and an angle (θ) from a reference direction (polar axis).
Next, we would determine the distance (r) and angle (θ) as follows:
r = √(3² + (-3)²)
r = √(9 + 9)
r = 3√2.
θ = tan⁻¹(-3/3)
θ = tan⁻¹(-1)
θ = 3π and 7π/4 (second and fourth quadrants).
Converting to degrees, we have:
θ = 135° and 315°.

If the factors of a quadratic function are (x 2) and (x − 9), what are the x-intercepts of the function?
The x-intercepts of the given quadratic function are -2 and 9.
What is a quadratic function?
A quadratic function is a function represented as, f(x) = ax2 + bx + c, with a, b, and c being integers and a not equal to zero. A parabolic curve represents the graph of a quadratic function.
A polynomial's highest degree reveals how many roots the polynomial has. The values for which the polynomial's numerical value is equal to zero are known as a polynomial's roots (also known as zeros of a polynomial). On a graph, the points where the polynomial's graph and the x-axis cross are the roots (x-intercepts).
Roots of the Quadratic Equation
Due to its degree of 2, a quadratic function can only have a maximum of two real roots. In order to find the roots of a quadratic equation, we equate its factors to 0. Thus, in this case, we have,
(x+2)*(x-9)=0
∴ x+2=0
⇒ x=-2
Similarly,
x-9=0
⇒ x=9
Hence, the x- intercepts of the given quadratic function come out to be -2 and 9.

Jill and Jack are exercising at a beach. They both start from the car park at one end of the beach. Jill runs at a constant speed and Jack walks at a constant speed. When Jill turns at the end of the beach to run back, she notices that Jack is then halfway along the beach. How far along the beach will Jack be when JIll next passes him
Jack is at (2/3) of the length of the beach (measuring from the point where they started).
How far along the beach will Jack be when JIll next passes him?Let's think that the whole beach is like a line track of length L.
We know that when Jill completes reaches the end (one complete run) Jack only completed half of it.
So in the time that jill covers the distance L, Jack covers a distance of L/2. So the ratio of their speeds is 2:1 (Jill's speed is double of Jack's speed).
At this point, Jill is on the end of the track and Jack is on the middle, so the distance between them is L/2.
Because of the ratios between the speeds, we know that when they meet again, Jill will have covered 2 thirds of that distance, and jack will cover the other third of that distance.
A third of that distance is:
(L/2)/3 = L/6
So, when they meet, Jack is at L/6 of the middle of the beach, which means that Jack is:
L/2 + L/6 = 3L/6 + L/6 = 4L/6 = 2L/3
Jack is at (2/3) of the length of the beach (measuring from the point where they started).

Marcia made spiral books to sell at her local craft fair. She forgot to count how many she made before the fair. She knows that she spent $176.80 in supplies to make the books. If each book requires two chipboard covers at a cost of $0.74 per cover and one spiral wire at a cost of $0.60, which equation can be used to find the number of books, n, she made?
A. 0.60n + 0.74n = 176.80
B. 0.60n + 1.48n = 176.80
C. 0.60n + 0.74 = 176.80
D. 0.60n + 1.48 = 176.80
Answer:
B) 0.60n+1.48n = 176.80
Step-by-step explanation:
0.60 for every spiral wire per book = 0.60*n
0.74 per chipboard cover, 2 needed for each book = 1.48 per book = 1.48*n
Put it together: 0.60n+1.48n = 176.80

The area of ∆ABC is 100 square centimeters. The area of ∆DEF is square centimeters.
The area of the similar triangle named ∆DEF is; 4 square centimeters.
How to find the area of a similar triangle?
We are given that ∆ABC is similar to ∆DEF.
The perimeter of ∆ABC is five times the perimeter of ∆DEF. Thus;
(Perimeter of ΔABC) = 5(Perimeter of ΔDEF)
Thus;
(Perimeter of ΔABC)/(Perimeter of ΔDEF) = 5
Thus, we can say that;
Scale factor, K = 5.
Since the area of ∆ABC is 100 square centimeters, Then;
(area of ∆ABC)/(area of ∆DEF) = K²
100/(area of ∆DEF) = 5² = 25.
(area of ∆DEF) = 100/25 = 4.
Thus, the area of ∆DEF is 4 square centimeters.
