Step-by-step explanation:
2x-3y= -14
5x+9y= -2
multiply the first one by 5 and the second one by -2 to get equal and opposite value of x.
➡️when you multiply,it will be
10x-15y= -70
-10x-18y= 4
cancel out each x value,then you get
-15y-18y= -70+4
-33y= -66, divide each side by -33 to get the value of y
⚪️y= 2
➡️substitute the value of y in the equation of (2x-3y= -14) to find the value of x
2x-3(2)= -14
2x-6= -14
2x= -14+6
2x= -8 divide both side by 2
⚪️x= -4
so the answer is (-4,2)
16 + 18 + 10 = 44
44 = x + 28
16 = x
x = 16
5 because if you divide the 24 ounces in 5 cups you get 4.8 but you round it up to get 5
Answer:
B. 110.5 square units
Step-by-step explanation:
The area of a rhombus is half the product of the diagonals.
A = (MK * JL)/2 = 13 * 17/2 = 221/2 = 110.5
Answer:
Step-by-step explanation:
You need to give us the choices. However, I will try and give you the answer.
The highest common factor is 8
8(x^2 - 3) This is the answer I think the question expects.
8(x - √3 )(x + √3) this is also possible
