Answer:
x = 57
Step-by-step explanation:
Median is the number that is halfway mark. If we are given a data, first we need to arrange them in ascending order and take the middle value. That is called median.
If we have odd number of data, we can easily find the middle value.
For instance, 1, 2, 3, 4, 5 here the number of data = 5 which is odd number.
The middle number is 3.
Therefore, median is 3.
If we have even number of data, we have to take middle two values, add them then divide by 2.
In this case, we are given even number of data
30, 45, x, 100
4 data which is even number of data.
Median is given as 51, we need to find the value of x.
The middle two numbers are 45 and x, we have to add them and divide by 2
Median = [Given: median = 51]
51 =
Multiplying both sides by 2, we get
51*2 = 45 + x
102 = 45 + x
Subtract 45 in both sides, we get
102 - 45 = 45 -45 + x
x = 102 -45
x = 57
The solution is, graph is D ,which graphs represents the solution set for 7(4x – 1 ) + 6x > –279.
An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
First, solve the inequality:
7(4x – 1 ) + 6x > –279
solving we get,
34x>-272
x>-8
Since x is greater than -8, you have the arrow point up the graph towards the positive side starting at -8.
Since it's greater than but not equal to -8, the circle is open.
Thus, The solution is, graph is D.

b) (2x- 5) (3x + 1)
c) (6x-5) (x + 1)
d) 6x + 1) (x - 5)
For the quadratic trinomial the following formula
, where are trinomial roots, holds.
1. For trinomial find the roots:
.
2. The factoring form is
Answer: correct option is B.
Answer:
x=3 and y=2
Step-by-step explanation:
We are given with two equations
Y=4x – 10
y=2
From the two equations we already have value y=2
To find out x, plug in 2 for y in the first equation
y= 4x -10
2 = 4x -10
add 10 on both sides
12= 4x
now divide by 4 on both sides
3= x
the value of x=3
so x=3 and y =2
