Put a dot on the 4 on the y line. then from that point go down 3 and to the right 4.
Solve each system by substitution. Check your solution. Writing How do you know that substitution gives the answer to a system of equations? ... You Would solve the second equationfor y and then substitute back into the first equation.
Look, Dav...
This is a simple ex of Pyth. Theorem
26^2=24^2 + (DB)^2
then: DB = 10
3.4 = -13.6 - 3.4c + 1.7c
3.4 = -13.6 - 1.7c
1.7c = -13.6 - 3.4
1.7c = 17
c = 10
from the equation<span> x^2 - 6x + 7 = 0 </span>, b is equal to -6. The form should become y = (x-(b/2)^2) + c. (<span>b/2)^2 is equal to 9. Hence,
</span>
0 = (x - 3)^2 -9 + 7
<span>0 = (x - 3)^2 -2
</span>2 = <span>(x - 3)^2
x should be equal to -1.5858 and -4.4142</span>
