Good day !
In this equation , you can solve the two equations directly .
You have been given the value of y In both cases.
So 3x+4=5x+12
=3x-5x=12-4
-2x=8
X=-4




Sorry if it’s incorrect!

Step-by-step explanation:

Easy:)

7)4a^{8}b^{12} \\8)25x^{6}y^{8}\\9)x^{9}y^{9}×xy^{2}

=x^{10}y^{11}

10)a^{3}×a^{8}b^{4}

=a^{11}b^{4}

11)4a^{2}b^{4}×9a^{4}b^{2}

=36a^{6}b^{6}

Have a nice day! :)

Find the complement and supplement of the angle with measure 40 degrees
mrs_skeptik [129]

Answer:

The complement is 50 and the supplement is 140

Step-by-step explanation:

Complementary angles add up to 90. Supplementary angles add up to 180. We simply need to subtract to find the difference to fill the gap.

90-40=50

180-40=140

The complement is 50 and the supplement is 140

what does the adjusted r squared tell us about the relationship between sales, price, and advertising? the model explains about
svp [43]

The modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.

<h3>Define the term adjusted r squared?</h3>

R-squared (R2) would be a statistical measure that quantifies the proportion of the variation explained from an independent variable other variables within a regression model for a dependent variable.

  • R-squared describes how much the variance with one variable describes the variance of the other.
  • So, if a model's R2 is 0.50, the model's inputs can explain roughly half of a observed variation.
  • A score of 70 to 100 shows that a specific portfolio closely reflects the underlying stock index, whereas a score of 0 to 40 indicates a relatively poor correlation the with index.
  • Higher R-squared scores also suggest that beta measurements are more reliable. The volatility of either a security or portfolio is measured by beta.

Thus, the modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.
