Choose the correct item from each drop-down menu to factor the trinomial 3x2 + 13x – 10 by grouping.
The factors of the given trinomial are (3x-2)(x+5).
What is trinomial?Trinomial is a polynomial having 3 terms. At least one variable and one operation (addition, subtraction, multiplication, division) must be present in an algebraic expression.
Given is a trinomial 3x²+13x-10, we need to factorize it,
So,
= 3x²+13x-10
To factorize a trinomial, we do find the product of the product of a and c (ax²+bx-c) and find its two factors so that we can add or subtract so that we can find the middle term (b) of the trinomial,
Here,
a = 3, c = 10
a × c = 30
Now,
15 and 2 are the factors of the 30, also 15 - 12 = 13 which is the middle term of the trinomial,
Therefore,
3x²+13x-10 = 3x²+15x-2x-10
= 3x(x+5)-2(x+5)
= (3x-2)(x+5)
Hence, the factors of the given trinomial are (3x-2)(x+5).

If a value in the _______ occurs more than once, then the relation is NOT a function.
Fill in the blank
The definition of a function is " a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output." (Mathinsight)
Therefore is a number (x values) appears more than once in the domain then this would not be a function since it doesn't fit the definition of a function.

The graph of a function is shown on the grid.
Which ordered pair best represents the location of the y-intercept?
Answer:
y-intercept = (0, -2)
Step-by-step explanation:
The y-intercept is the y-coordinate of the point (0, b) where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. Looking at your graph, it shows that the line crosses at point (0, -2).
Therefore, the correct answer is (0, -2).

y=41
x+y= 55
Step-by-step explanation:
Since a and b are parallel you know that 123° and 3y are the same degree, so 123 divided by 3 because its 3×y= 41 so y=41
the line123° and 4x+1 are on has to equal 180 because its a straight line, 180-123= 57. 57- 1 because its not with the x= 56. 56÷4 because its 4×x/its with the x= 14. Hope thsi helps :)

Hannah drove her car 318.4km in 4h
a) Calculate her average speed=
b) At this speed, how far can she expect to travel in 5.5 h? =
Answer:
a) 79.6
b) 437.8
Step-by-step explanation:
First, you have to do 318.4/4 to find the rate she goes in the duration of an hour. The rate is 79.6, which means she travels at a rate of 79.6 kilometers per hour.
Then, you have to find the distance she takes to travel in 5.5 hours, so you have to do 5.5*79.6 which is 437.8.
So, Hannah travels 437.8 kilometers in 5.5 hours.

Answer: 2. Linear pair postulate
4. 60 + mACB=180
5. mACB=120
6. definition of obtuse angle
The value of straight angle ∠BCD = 180° thus the angle ∠ACB = 180°- 60° = 120° therefore, the given triangle ABC is the obtuse triangle.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
As per the given triangle ABC with extended line CD.
Since CD is colinear with BC, therefore, BCD will be a single straight-line segment.
The ∠BCD is straight angle so it will be 180°.
∠BCD = ∠ACB + ∠ACD
∠ACB + 60 = 180
∠ACB = 180 - 60 = 120°.
An obtuse triangle is a triangle whose one or more interior angle is greater than 90°.
Since∠ACB > 90° therefore triangle ABC is an obtuse angle.
Hence "The value of straight angle ∠BCD = 180° thus the angle ∠ACB = 180°- 60° = 120° therefore, the given triangle ABC is the obtuse triangle".

Two sides of a triangle have lengths 6 and 16. Which inequalities represent the possible
lengths for the third side, x?
Answer:
22 > x > 10
Step-by-step explanation:
By the triangle inequality, the length of the 3rd side must be less than the sum of the two other sides and greater than the positive difference of the other two sides. Thus, 6 + 16 > x > 16 - 6
22 > x > 10
