this is system of equations

2x + 5y = -1 times this one by 5 to make the y's opposite

-10x -25y = 5

10x - 25y = -5 (this is it times by 5, now add them)

__________

0 + 0 = 0

now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.

Answer: x < -44

Step-by-step explanation:

alright my fellow dude gamer, i want you to know that "a number" is basically just x

so lets do this

$\frac{1}{4}x + 13 < 2$

ok now we are going to solve for x, no?

$\frac{1}{4}x < -11$

i just subtracted 13 from both sides

now we divide -11 by 1/4

$x < -44$

MAGIC! ABSOLUTELY FANTASTIC! OH MY GOODNESS AHHHHHHH

(18) POINTS pLEASE HELP

JulijaS [17]

Answer:

(x-4)(x-3)

Step-by-step explanation:

$x^{2} -7x+12\\$

multiply 1 and 12= 12

find two numbers that multiply to get twelve AND add together to get -7(the middle number)

the two numbers are -3 and -4 (they add up to get -7 AND multiply together to get 12)

plug in these numbers for -7x

$x^{2} -3x-4x+12$

x(x-3)-4(x-3)

the bolded is the first binomial and the second binomial is in the parenthesis.

(x-4)(x-3)

I hope this helps!

Y=1020-85x because since it's a decrease it would be goung do, hence the subtraction
