Solve the system by graphing.
y= 2x-1
y= x^2-9
Answers
Answer:
Step-by-step explanation:
Answer:
The said explanation is the answer.
Step-by-step explanation:
1) Graphing the first function (y = 2x-1). When the exponents of the variables are all 1, that is there are no square, cubes, etc. the equation is a line. Then it is enough to find two points to draw it. We can calculate two points assigning a number to x and calculating the corresponding number for y. For example, when x= 0 y= 2 times 0 -1 = -1. Then the line will pass from the point (0,-1). We need a second point, we can take x=1, then y = 2 times 1 -1 = 1. The line will pass from (1,1). We can mark the two points on the plane and draw the line from these two points.
2) Graphing the second function (y = x^2-9). A quadratic equation is of the form: ax^2+bx+c= 0. We have: y= f(x) -9. Set y=0. We have the quadratic equation: x^2-9=0. Using the algebraic identity: a^2-b^2=(a+b)(a-b). We can rewrite x^2-9=0 as x^2-3^2=0: [(x+3)(x-3)=0] - [(x+3)=0,(x-3)=0] - [x= -3, x= 3]. Hence, there are two solutions for x. So we have two x-intercepts: (-3,0) and (3,0). To find the y-intercept, set x=0: [(y = (0)^2-9=0)] - [(y=-9)]. Hence the y-intercept: (0,-9)
In conclusion, this system of equations at most has two real solutions, since two points of both functions intersect each other.
Here's the graph:

Find the value of d so the line that passes through (a,b) and (c,d) has a slope of 12.
Answers
Answer:
d = 12c-12a+b
Step-by-step explanation:
The formula for calculating the slope of a line passing through two points (x1, y1) and (x2, y2)is expressed as:
m = y2-y1/x2-x1
Given the coordinates (a,b) and (c,d) and slope m = 12
Substitute into the formula as shown:
m = d-b/c-a
12 = d-b/c-a
Make d the subject of the formula:
12 = d-b/c-a
cross multiply
12(c-a) = d-b
12c-12a = d-b
add b to both sides
12c-12a + b = d-b+b
12c-12a + b = d
Hence d = 12c-12a+b

Deepak is measuring sides and angles of triangle FGH to determine whether it is congruent to triangle MNP shown below. Triangle M N P. Side P N is 26.7 centimeters, side M N is 18.3 centimeters, and side P M is 14.2 centimeters. Angle P is 40 degrees, angle N is 30 degrees, and angle M is 110 degrees. Deepak found that Angle G has a measure of 50° and Segment F H is 18.3 centimeters long. Does he need to continue measuring sides and angles of triangle FGH and why? No, he knows that the triangles are congruent because there are corresponding sides and angles that are congruent. No, he knows that the triangles are not congruent because those measurements are not equal to the corresponding parts of triangle MNP. Yes, he must verify that the other two side lengths and the other two angle measures are the same as those found in triangle MNP. Yes, he must only verify that the other two angle measures are the same as those found in triangle MNP.

B. No, he knows that the triangles are not congruent because those measurements are not equal to the corresponding parts of triangle MNP.
Step-by-step explanation:
I took the test.
The correct option is B. No, he knows that the triangles are not congruent because those measurements are not equal to the corresponding parts of triangle MNP.
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
We are given that Deepak is measuring sides and angles of triangle FGH to determine whether it is congruent to triangle MNP,
In Triangle M N P.
Side P N = 26.7 centimeters,
M N is 18.3 centimeters,
P M is 14.2 centimeters.
Angle P is 40 degrees, angle N is 30 degrees, and angle M is 110 degrees.
He found that Angle G has a measure of 50° and Segment F H is 18.3 centimeters long.
Based on the definition, two triangles are congruent if the three sides are equal and the three angles are equal.
Hence, he need to know the other lengths of the sides of the triangle and the others angles to know if they are congruent or not.
