Answer:
{4, 13}
Step-by-step explanation:
Represent the integers by I and J. Then I + J = -17 and I*J = 52.
Let's solve this system using substitution. Solve the first equation for I as follows:
I + J = -17 becomes I = -J - 17
Substitute -J -17 for I in the second equation:
(-J - 17)*J = 52
Performing the indicated multiplication, we get:
-J^2 - 17J - 52 = 0
Let's solve this using the quadratic formula. The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is
(-17)^2 - 4(-1)(-52), or 289 - 208, or 81. This result is positive, so we know that the quadratic equation has two real, unequal roots. They are:
17 ± √81 17 ± 9
J = --------------- = ---------------
2(-1) -2
Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and
J = (17 - 9)/2 = 8/2, or J = 4

Solve the system y = -x + 7 and y = -0.5(x - 3)^2 + 8
Step-by-step explanation:
-x+7=-0.5(x-3)^2+8
-x+7=-0.5x^10 -4.5^10
am I getting ...!?
Answer:
(-1,6) and (-7,0)
Step-by-step explanation:
-x+7=-0.5(x-3)^2+8
times both sides by -2
2x-14=(x-3)^2-16
expand
2x-14=x^2-6x+9-16
add 14-2x to both sides
0=x^2-8x+7
factor
0=(x-7)(x-1)
set to zero
0=x-7
7=x
0=x-1
1=x
so find y
y=-x+7
y=-1+7
y=6
or
y=-7+7
y=0

Can somebody please help me out with this. We have to do it point slope form.
[tex]y - y_{1} = m( x - x_{1})[/tex]
Explanation:
The formula y - y1 = m(x - x1) is usually described as the 'point-slope form' for the equation of a line. It is useful because if you know one point on a certain line and the slope of that certain line, then you can define the line with this type of formula and, thus, find all the other points on that certain line.
