Answer:
The graph of the system of equations solves the equation [tex]-\frac{1}{4}[/tex] x + 2 = 2x - 7 ⇒ C
Step-by-step explanation:
Let us revise some important notes about the slope and y-intercept of a line
The form of the linear equation is y = m x + b, where m is the slope and b is the y-intercept
If the line has a positive slope then its direction will be to the rightIf the line has a negative slope then its direction will be to the leftThe y-intercept (0, b) is the the point of intersection between the line and the y-axis
If the line cuts the y-axis at a point above the x-axis, then b is positiveIf the line cuts the y-axis at a point down the x-axis, then b is negativeTo solve our question without any calculation, let us find the direction of the slopes and their y-intercepts
∵ The direction of the blue line is to the left
→ That means m in the equation is negative
∴ Its slope is negative
∵ The line intersects the y-axis at point (0, 2)
→ That means b in the equation = 2
∴ The number in the equation is 2
→ Look at the answer we have two answers have negative slope and
y-intercept 2 in the left hand side ⇒ C and D
∴ The equation of the blue line is represented by the left side [tex]-\frac{1}{4}[/tex] x + 2
→ that means the equation of the red line is represented by the right side
∵ The direction of the red line is to the right
→ That means m in the equation is positive
∴ Its slope is positive
→ Only C has a positive slope in the right side
∴ The equation of the red line is represented by 2x - 7
The graph of the system of equations solves the equation [tex]-\frac{1}{4}[/tex] x + 2 = 2x - 7
Another way:
You can solve each equation to find the value of x, then substitute it in one side of the equation to find y , the values of x and y must be (4, 1) as the point of intersection of the two lines in the graph

A school has 625 students and 25 teachers. Which of these statements is true based on this information? A) The school has a ratio of 5 students to 1 teacher. B) The school has a ratio of 5 teachers to 1 student. C) The school has a ratio of 25 students to 1 teacher. D) The school has a ratio of 25 teachers to 1 student.
The statement that is true based on the information that a school has 625 students and 25 teachers is that the school has a ratio of 25 students to 1 teacher.
According to the question,
We have the following information:
A school has 625 students and 25 teachers.
Now, we have to find the ratio using the given information.
Ratio of students to the teachers can be better understood in simple terms as the number of the students divided by the number of the teachers.
Ratio of students to the teachers = Number of students : number of teachers
Ratio of students to the teachers = 625:25
Dividing both the numbers by 25,
Ratio of students to the teachers = 25:1
So, the school has a ratio of 25 students to 1 teacher.
Hence, the correct option is C.

Solve by completing the square:
x^2 + 2x - 3 =0
a. - 3 or 1
b. X-3 or -1
C. - 3 or -1
d. 2-3 or 1
Please select the best answer from the choices provided
Answer:
a
Step-by-step explanation:
Given
x² + 2x - 3 = 0 ( add 3 to both sides )
x² + 2x = 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 3 + 1
(x + 1)² = 4 ( take the square root of both sides )
x + 1 = ± [tex]\sqrt{4}[/tex] = ± 2 ( subtract 1 from both sides )
x = - 1 ± 2
Thus
x = - 1 - 2 = - 3
x = - 1 + 2 = 1
Y = -3x-2 Slope intercept form
Answer:The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

3.d) A pattern has 4 blue triangles to every 12 yellow triangles. What is the ratio of blue triangles to all triangles? * O 4:12 O 12:4 O 4:1 O 1:4
Explanation:
For every 4 blue, we have 12 yellow. This means 4+12 = 16 total.
The ratio of blue to total is 4:16 which reduces to 1:4 when we divide both parts by 4. The order of the values matters since 1:4 is different from 4:1.
Kira started a game at 4:37 PM and finished it at 5:16 PM.
How long did it take her? Give your answer in minutes.
Answer:
39
Step-by-step explanation:
4:37 till 5:00 is 23 minutes.
+ 16 minutes
= 23 + 16
Answer:
39 minutes
Step-by-step explanation:
First, find how much time passed between 4:37 PM and 5 PM.
Since there are 60 minutes in an hour, subtract 37 from 60:
60 - 37
= 23
There are 16 minutes in between 5 PM and 5:16 PM.
So, add the 23 minutes to 16:
23 + 16
= 39
So, it took her 39 minutes

The angle between 0 and 2π in radians that is coterminal with the angel 19π/4 in radians is what?
Answer:
29/24π
Step-by-step explanation:
To get coterminal angles, you simply have to add or subtract 2π
In this problem, we are looking for a coterminal angle that is between
0 and 2π, so we will add 2π to −19/24π.
−19/24π+2π
=
−19/24π+48/24π
=
29/24π
29/24π
is the answer to the question.
[tex]\frac{11\pi }{4}[/tex] is the coterminal between of [tex]\frac{19\pi }{4}[/tex] between (0, 2[tex]\pi[/tex]).
What is coterminal angle?
Coterminal angles are the angles that have the same initial side and share the terminal sides.
How to find the coterminal angles?To find the coterminal angle of an angle, we just add or subtract multiples of 360 degrees from the given angles.
According to the given question.
We have
Angle = [tex]\frac{19\pi }{4}[/tex]
Since, the coterminal angle is to be between 0 and 2π.
Therefore, we subtract 2π from [tex]\frac{19\pi }{4}[/tex]to get coterminal angle.
⇒ [tex]\frac{19\pi }{4} -2\pi[/tex] [tex]= \frac{19\pi -8\pi }{4} =\frac{11\pi }{4}[/tex]
Hence, [tex]\frac{11\pi }{4}[/tex] is the coterminal between of [tex]\frac{19\pi }{4}[/tex] between (0, 2[tex]\pi[/tex]).
