8+- 6 - 5 = 8x + 1 - 3x
= -3 + 2 = 5x +1
= -3 -1 = 4x +1 -1
= -3 + x - x = 5x - +1
= -3 = 4x + 1
1 = 4
= -4 = 42

Oc. Multiply the second fraction by = 2
Multiply the first fraction by
OD.
Answers
Answer:
Option C
Step-by-step explanation:
Difference of the two expressions has been written as,
[tex]\frac{3x}{x^2-7x+10}-\frac{2x}{3(x-5)}[/tex]
To rewrite this expression as one expression,
First he factored the the denominators,
[tex]\frac{3x}{(x-2)(x-5)}-\frac{2x}{3(x-5)}[/tex]
Then Juan will make the denominators of both the terms equal,
For which he will multiply the second expression by [tex]\frac{x-2}{x-2}[/tex].
[tex]\frac{3x}{(x-2)(x-5)}-\frac{2x(x-2)}{3(x-5)(x-2)}[/tex]
Option C will be the correct option.

In the slope-intercept form, which variable
represents the slope/measure of change?
Answers
Step-by-step explanation:
Hey there!
We know that the slope intercept is; y = mx+b.
Where "m" represents the slope. And "b" represents the y-intercept.
Example:
If the question is as; y = 3x +8
Then your slope of the slope intercept form is "3" where as "8" is y-intercept.
So, the variable"m" represents the slope.
Hope it helps...

A consumer magazine wants to compare the lifetimes of ballpoint pens of three different types. The magazine takes a random sample of pens of each type and conduct an ANOVA test. After the calculation, the F statistic is 1.62 and the p-value is 0.26. What is a correct decision at significance level of 0.1?
Answers
Answer: Fail to reject H0
Step-by-step explanation:
Given that:
P value = 0.26
α = 0.1
The values of both p and α can be compared in other to make a decision on whether to reject or fail to reject the Null hypothesis
Decisions :
If the p value > α (fail to reject null)
If p value < α ( Reject null)
In the scenario above :
0.26 > 0.1 ; p value > α
Since the p value is greater than alpha ; we fail to reject the Null

Answer:x=20 y=70
Step-by-step explanation:
Answer:
x=20, y=70
Step-by-step explanation:
∠40°+∠adjacent to it =180°
∠adjacent= 180-40=140°
we see that 2 of the sides of one of the small triangles are congruent so that triangle is isoscel so the base angles are congruent as well
because sum of angles in a triangle has to be 180,
140 +x+x=180 so x=20°
from the right triange we see thhat y +90+20 =180 because sum of angle in a triangle has to be 180 so y=70
