Answer:
YES
Step-by-step explanation:
The equation,
, would be an identity if the equation remains true regardless of the value of x we choose to plug in into the equation.
Let's find out if we would always get a true statement using different value of x.
✍️Substituting x = 1 into the equation:



(TRUE)
✍️Substituting x = 2 into the equation:



(TRUE)
✍️Substituting x = 3 into the equation:



(TRUE)
Therefore, we can conclude that the equation,
, is an identity.
Answer:
that is the equation of the line, its slope is 1 and the y-intercept is 1 y = x + 1
Step-by-step explanation:
we can calculate the slope of this line passing through (4,5) and (8,9) like this:
m = (y2 - y1)/(x2 - x1)
m = (9 - 5)/(8 - 4)
m = 4/4
m = 1
so the slope is 1, and now we can use the equation of one point and the slope to write the line's equation:
y - y1 = m(x - x1)
y - 5 = 1*(x - 4)
y - 5 = x - 4
y = x + 1
that is the equation of the line, its slope is 1 and the y-intercept is 1
Answer:
Mean: 49
Mode: none, since all the numbers only appear once
Median: 48
Range: 69
Step-by-step explanation:
53+64+19+25+88+48+46 = 343
343/7= 49 (mean)
19, 25, 26, 48, 53, 64, 88 (middle number is 48, so the median is 48)
Range= largest number-smallest number
88-19= 69 (range)
Answer:
409 is what I got.
Step-by-step explanation:
361 cm, as the square's area
and 48 as the area for the triangle.
Are you sure those are the answer choices because I'm getting 409.
