5. Write equations in slope-intercept form for three different lines that intersect at (–2, 3). Show your work.
Answer:
Equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
Step-by-step explanation:
General equation of slope intercept form : [tex]y-y_1=m(x-x_1)[/tex]
We are supposed to find equations in slope-intercept form for three different lines that intersect at (–2, 3).
[tex](x_1,y_1)=(-2,3)[/tex]
Substitute the value in the general equation
y-3=m(x+2)
Now substitute any 3 values of m
At m = -1
[tex]\Rightarrow y-3=-x-2 \\\Rightarrow y=-x+1[/tex]
At m =0
[tex]\Rightarrow y-3=0 \\\Rightarrow y=3[/tex]
At m =1
[tex]\Rightarrow y-3=x+2 \\\Rightarrow y=x+5[/tex]
They all intersect at the given point.
So, equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
Answer:
y-3=-x-2
y=-x+1
y-3=0
y=3
y-3=x+2
y=x+5

Answer:
A. 1/√2
Step-by-step explanation:
I just took the test.
Good luck mate!
The value of Sin 45° is 1/√2
What are trigonometric functions?In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.
Given here Sin 45° and Sin 45 degrees is the value of sine trigonometric function for an angle equal to 45 degrees. The value of sin 45° is 1/√2 or 0.7071 (approx).
Hence, the value of Sin 45° is 1/√2

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is
worth either 5 points or 2 points. Write a system of equations that can be used to find how many problems of each
point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
O x + y = 29, 5x + 2y = 100
x + y = 100, 5x + 2y = 29
5x + y = 29, 2y + x = 100
O 2x + y = 100, 5y + x = 29
Answer:
Step-by-step explanation:
From the conditions given, the total number of the problems should be 29. This means that the sum of x and y should be 29. With this and the point-system, the best system of equation that is useful for this problem is,
x + y = 29
5x + 2y = 100
The answer is the second choice.
Answer:
The correct answer is A
A. x + y = 29, 5x + 2y = 100

Solve for X please help
Answer:
71 degrees
Step-by-step explanation:
Sum of three angles of triangle=180
Let's find the third angle
73+36=109
180-109=71
Vertical angles are congruent so x= angle 3
So x is 71 degrees
Answer:
79 degrees
Step-by-step explanation:
Remember: Triangles always add up to 180 degrees.
x is vertical to the missing angle in the triangle, which means x and the missing angle are equal.
to find the missing angle in the triangle, you add up the other angle measurements and subtract from 180.
36+73=109
180-109=71
The third mising angle is 71 degrees.
this means x is also 71.
Hope this helps!
