Answer:
1
Step-by-step explanation:
This is a quadratic function which is parabolic in shape. By definition, it has a vertex which serves as the (only) max or min point; 1 turn.
What = 6 x y = 72? 12! X=12 in!!
Volume 72+72= Your answer!! (144) I think! :D
Answer:
y = 28 degrees
Step-by-step explanation:
First thing: find the value of x. Note that the 34 degree angle and the angle x - 5 are equal because this is an isosceles triangle. Thus, 34 = x - 5, and so x = 39.
Second: the three interior angles must add up to 180 degrees.
Thus, 34 + 39 -5 + 4y = 180.
From this we get:
4y = 180 - 34 - 39 + 5, or
4y = 112.
Therefore, y must be 112/4, or 28.
Step-by-step explanation:
first find two numbers u multiply to get 7 and add to get 8: (1×7)=7,(1+7)=8
so in the first bracket u put (x +1) n in the other (x+7)
ans: (x+1)(x+7)
Answer:
To decide whether to add or subtract, determine if the values of the coefficients are the same or opposites:
. If the values are the same, subtract the equations.
• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given


Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:


Rewrite the second equation


The coefficient of y are the same, so we subtract;




<em>See that y has been eliminated</em>
