lisov135 [29]
x \geqslant 10
the way you graph this is by making a number line <-----8------9-----10-----> then putting a closed cirlce on the number 10 in the number line with a line going to the right. it would be greater than or equal to because they pay 10 dollars or more to get free greeting card

What two numbers multiply to -40 and add to 10
andreev551 [17]

Answer:

5 + sqrt(65), 5 - sqrt(65)

Step-by-step explanation:

x + y = 10

x×y = -40

so, two equations with 2 variables. using one equation to express one variable by the second. and then using the second equation to solve and calculate the second variable. and then by knowing the second variable we calculate the first.

=> x = 10 - y

=> (10-y)×y = -40

=> -1×(10-y)×y = 40

=> (y-10)×y = 40

=> y^2 - 10×y - 40 = 0

remember the solution for a quadratic equation

a×x^2 + b×x + c

is

x = (-b ± sqrt(b^2 - 4×a×c)/(2×a)

in our case

a = 1

b = -10

c = -40

and we used "y".

so,

y = (--10 ± sqrt((-10)^2 - 4×1×(-40))/(2×1) =

= (10 ± sqrt(100 + 160))/2 = (10 ± sqrt(260))/2 =

= (10 ± sqrt (4×65))/2 = 10/2 ± 2×sqrt(65)/2 =

= 5 ± sqrt(65)

=>

for y = 5 + sqrt(65), x = 10 - 5 - sqrt(65) = 5 - sqrt(65)

for y = 5 - sqrt(65), x = 10 - 5 + sqrt(65) = 5 + sqrt(65)

Find the distance of GF if G(9,1) and F (0,2)
galina1969 [7]

Answer:

9.06 units

Step-by-step explanation:

The distance formula for points on a graph is basically the Pythagorean Theorem

√(x2 - x1)² + (y2 - y1)²

Plug in the values and you'll get √82, which equals about 9.05539, or 9.06
