(-2,-5)
because
y= y
x^2+10x+ 11 = x^2+x -7
10x-x = -7-11
9x=-18
x=-2

so y = (-2)^2+(-2)-7 = 4-2-7 =-5

Point G is in love segment FH give an FH equals 4XGH equals XNFG Eagles 2X +10 determine the numerical link of FG

victus00 [196]

Answer:

FG= 30

Step-by-step explanation:

Point G is on line Segment FH

Given

FH= 4x

GH= x

FG= 2x+10

If the point G is on the line FH then the total of the two line segement FG and GH must be equal to FH

FH= FG+ GH

Putting the values in the above equation:

4x= 2x+10+x

4x= 3x+10 Solving for x

10= 4x-3x

10= x

FG= 2x +10

FG = 2(10) +10 Putting the value of x

FG= 20+10

FG= 30

Check :

FH= 4x= 4(10)= 40

GH= x= 10

FG = FH- GH= 40-10= 30

You draw one card at random from a standard deck of 52 playing cards. Find the probability that (a) the card is an even-numbered

DerKrebs [107]

Answer:

$P(even )=\frac{20}{52} =\frac{5}{13}$

$P(heart or diamond)=\frac{13}{52} +\frac{13}{52} =\frac{1}{2}$

$P(nine or face card)=\frac{4}{52} +\frac{12}{52} =\frac{4}{13}$

Step-by-step explanation:

You draw one card at random from a standard deck of 52 playing cards

Total cards = 52

5 even numbers in each suit. 4 times 5 = 20 even number cards

$P(even )=\frac{20}{52} =\frac{5}{13}$

(b) the card is a heart or a diamond

there are 13 heart and 13 diamonds

$P(heart or diamond)=\frac{13}{52} +\frac{13}{52} =\frac{1}{2}$

There are 4 nine and 12 face cards

$P(nine or face card)=\frac{4}{52} +\frac{12}{52} =\frac{4}{13}$
