Y= 2x-1
Explanation: First, you find slope. If the first point it x-axis point is 0 and the second x-axis point is 1 then you already know the answer is over 1, so you have to figure out how many up you are going on the y-axis from -1 to 1. Which is 2, so your slope is 2/1 or just 2. Next, you find your y-intercept, which is where the line crosses the y-axis, and the easy way to find this is finding what y is equal to when x is equal to 0, in the problem you are told (0, -1) as a point, so they gave you your y-intercept right there, which is -1. Finally you right the equation in slip intercept form (y= mx+b) which is y= 2x-1
(7x^2-3x)+4x^2
7x^2+4x^2-3x
11x^2-3x
Answer: 11x^2-3x.
You just combine like terms.
Since two sides are congruent, the opposite angles are congruent.
Angles A and B have the same measure.
m<A = m<B = 34
m<A + m<B m<C = 180
34 + 34 + m<C = 180
68 + m<C = 180
m<C = 112
m<C = 4y = 112
4y = 112
y = 28
Answer:
D. The three points could be the vertices of a triangle.
Step-by-step explanation:
- collinear points : points are said to be collinear if they lie on the same line.
- so, any three given points need not be collinear because, they can even be the vertices of a triangle.
- this is explained in the option D so, it is correct.
- option A is wrong because, those three points can be collinear also i.e if we put three points on a line, then they will be collinear.
- option B is wrong because, it is saying that they do not have to be collinear. but the fact is, they can be collinear.
- option C is wrong because, four points also need not be collinear. they can be vertices of a square!
