What is the solution to the system of equations?

Mathematics
1 answer:
Minchanka [31]3 years ago
4 0

Answer:

  (1, –5)

Step-by-step explanation:

It is relatively easy to try the offered solutions to see what works.

<u>(1, -5)</u>

  3(1) +10(-5) = -47 . . . true

  5(1) -7(-5) = 40 . . . true

(1, -5) is the solution

_____

As a check, you can try some of the other choices:

<u>(1, 5)</u>

  3(1) +10(5) ≠ -47

<u>(-1, -5)</u>

  3(-1) +10(-5) ≠ -47

<u>(-1, 5)</u>

  3(-1) +10(5) ≠ -47

None of the other choices works in the first equation, so they're not the solution.

F(x)=-12x - 2x + 60x² +14x-60
Leona [35]

Answer:

x=±1. are the factors of the quadratic equation.

Step-by-step explanation:

Given quadratic expression, f(x)=-12x - 2x + 60x² +14x-60

Rearranging and adding the terms in the expression and equating to zero.

f(x)= 60x² -60=0

60(x² - 1) =0

The zero product property states that if the product of a⋅b=0 then either a or b equal zero or both of them must be equal to zero. This basic property helps us solve the quadratic equations like (x+2)(x-5)=0 where x =-2,5.

from the zero product property we can infer that 60≠0⇒x² - 1=0

⇒(x+1)×(x-1) = 0

⇒x=±1.

Therefore, x=±1. are the factors of the quadratic equation.

A baker uses a coffee mug with a diameter of 8cm to cut out circular cookies from a big sheet of cookie dough. What is the area
kodGreya [7K]
Diameter = 8 cm

radius = diameter/2 = 4 cm

A = pi * r^2

A = pi * (4 cm)^2

A = 16pi cm^2
