Answer:
x = -7/5 y = -6/5
Step-by-step explanation:
System:
y = -2x-4
AND
y= 3x+3
therefore -2x-4 = 3x+3
-2x-3x = 3 + 4
-5x = 7
x = -7/5
y = 3(-7/5) + 3 = -21/5 + 3 = -6/5
Given the function f(x)=x^2+5x+5 , to get the zeros we solve using quadratic formula;
x=[-b(+or-) sqrt(b^2-4ac)]/(2a)
from our function;
a=1,b=5, c=5
thus,
x=[-5(+or-)sqrt(5^2-4*1*5)]/(2*1)
x=[-5(+or-)sqrt(25-20)]/2
x=[-5+/-sqrt(5)/2
The answer is option C
Answer:
Step-by-step explanation:
A parallelogram is a 4-sided polygon whose opposite sides are equal. By definition, opposite angles are also equal. A square, rectangle, or rhombus are considered as a parallelogram. Among the choices, the correct answer is D. "Opposite angles are congruent"
You would round the hundreds.
but it depends what numbers there are of population like if you get into thousands round by thousand hundreds equals round by hundreds.
Answer:
y = 27
Step-by-step explanation:
line segment BA and CD are congruent, turn them into an equation
3y - 59 = y - 5
subtract 1y from both sides, you get 2y - 59 = -5
then, add 59 to both sides and the equation is now 2y = 54
divide each side by 2 and you get the value of y (y = 27)
