Please!! What is the slope of each line? <br><br> Are they the same or different?
Korvikt [17]

Given:

The graph of two lines.

To find:

The slope of each line and check whether they are same or different.

Solution:

If a line passes through two points, then the slope of a line is:

m=\dfrac{y_2-y_1}{x_2-x_1}

From the graph 1, it is clear that the line passes through the points (2,175) and (3,165). So, the slope of first line is:

m_1=\dfrac{175-165}{3-2}

m_1=\dfrac{10}{1}

m_1=10

The slope of first line is 10.

From the graph 2, it is clear that the line passes through the points (1,175) and (2,165). So, the slope of first line is:

m_2=\dfrac{175-165}{2-1}

m_2=\dfrac{10}{1}

m_2=10

The slope of second line is 10.

m_1=m_2

Therefore, the slopes of both lines are same, i.e. 10.

Two students factored 2x^2 + 6x - 20. Leuko said that the factorization was (2x - 4)(x + 5). Ray gave the factorization as (x -
shutvik [7]

Answer:

See explanation

Step-by-step explanation:

If you FOIL both of them, you see that they are both correct, but they both need to factor out a 2 and then they will both have the same thing.

2(x - 2)(x + 5)

Can somone help me with this 1 problem? In the figure shown, △RST is an isosceles triangle with RS≅RT. Which is the measure of ∠
anastassius [24]
In an isosceles triangle, the angles opposite to the two equal sides are also congruent.
Based on your information, T and S are congruent. So we know that the measure of angle T is 3x+7. But we need to solve for x. Let's add all the angle values together and set it to 180 because the angles of a triangle sum to 180.
1) 2(3x+7) + 2x - 2 = 180
2) 6x + 14 + 2x - 2 = 180
3) 8x + 12 = 180
4) 8x = 168
5) x = 21
6) m<T = 3x + 7 = 3(21) + 7 = 63 + 7 = 70
I got C, but it is always helpful to double check work. Hope this helps!
