Answer:
B and D
Step-by-step explanation:
The quadratic formula is
. Here a=20, b=-26, and c=8.
Substitute and you'll have:
This means the solutions are 26 - 6/ 40 and 26 + 6/ 40.
It simplifies to 1/2 and 4/5.
Answer:

Step-by-step explanation:
the general equation of a circle is

with (h,k) being the centre of the circle and r the radius
ANSWER
C. The left end goes up; the right end goes down.
EXPLANATION
The given function is

We analyze the end behavior of this function using the leading term.
The leading term of this function is:

Since the degree(5) is odd and the leading coefficient (-2) is negative, the graph rises on the left and falls on the right.
In other words, the left end of the graph goes up and the right end goes down.
The correct option is C.
If we expand bx to jx and kx we have:
5y^2-2y-7
5y^2-7y+5y-7 then factor...
y(5y-7)+1(5y-7)
(y+1)(5y-7)
So the other factor is:
(y+1)
First, we must express the ratio of rent to Joel's total earning. 375 out of 1500 in its simplest form is 1/4. To express a value in percentage, we must multiply it to 100. Thus, for this case, we have
1/4 x 100 = 25%
That means, out of a total of 100%, Joel spends 25%<span>of his income on rent.</span>
