Answer:
<7=120
<8=60
Step-by-step explanation:
<2 and <7 are alternate exterior angles. <7 and <8 are complementary sor just do 180-120 and you will get 60
In a quadratic equation with the general formula of:
ax^2 + bx + c = 0
The discriminant is equal to b^2 - 4(a)(c). If the answer is a perfect square, then there are two real numbers. If not, then there are no real number root.
The discriminant for this equation is
(-6)^2 - 4(3)(1) = 24
Since 24 is not a perfect square, there are no real number roots.
Answer:
a = 2
Step-by-step explanation:
Multiply equation by 2a to get rid of denominators.
10 + a = 12
a = 2
From the text of the task we can write the equation:
Answer:
<u>The best prediction will be B) 35 </u>
Step-by-step explanation:
By looking at the scatterplot ,
<em>we can see that it the City MPG vs Highway MPG approximately falls on a straight line.</em>
we can either find the slope of it ( which might be a little out of syllabus ) or <em>we can extend the line connecting the maximum number of points.</em>
When we do so, We get a line as attached in the diagram.
And we extend it.
<em><u>From the graph attached we find that the value of City MPG falls somewhere in between the lines of 30 and 35</u></em><u> (</u><em><u> </u></em><u>though this is just and approximation).</u>
thus the more appropriate answer would be : 35
