whats the equation of the line in fully simplified slope-intercept form?pls help me
Answer:
y=-x+2
Step-by-step explanation:
the slope is change in y over change in x and as y goes down one x goes over one
the y intercept is at (0,2)

Step-by-step explanation:
For reference the quadratic equations looks like this
(-b±[tex]\sqrt{b^2-(4*a*c)}\\[/tex])/2a
Amy's mistake (and solution)
We can see that when amy mulitplied c she wrote 20 instead of -20 (in step 1). She can fix this by writing (4*1*-20) instead
Richard's mistake (and solution)
When richard messed up on step 5 when he wrote (6-2i)/2. You only would write the i if the negative was in the radical (but in this case it's outside). You would fix this by just getting rid of the i entirely (and keeping the 2)
I'm not really too sure how you would do three but I'll give it a shot anyways
our equation will look like this: x²+2x
which means our quadratic equation would look like this
[tex]\frac{-2+/-\sqrt{2^2-4*1*0}}{2}\\=\\\\\frac{-2+/-(2)}{2}\\\\\\= -1+/-(1)\\\\-1+1=0\\-1-1=-2[/tex]
When I write +/- I mean plus or minus giving us -2 and 0 as our solutions
which expression is equivalent to 4(6 -2x)
( A. 24 - 8x)
( B. 24 - 6x)
( C. 10 - 8x)
( D. 10 - 6x)
The expression equivalent to 4(6 -2x) is A. 24 - 8x.
What is an expression?An expression is a sentence in two or more than two variables separated by addition or subtraction or both. There are many types of mathematical expressions they are algebraic expressions, trigonometric expressions, logarithmic expressions, and many more.There are also three basic math properties they are commutative law which states a + b = b + a, associative law which states (a+b) + c = a + (b+c) and distribute law which states a(b+c) = ab + ac.
We know distributive property states that a(b+c) = b + bc.
∴ The expression 4(6 -2x) is equivalent to,
= 24 - 8x.

Victoria and Javier are collecting aluminum for a community service project. Victoria previously collected 56 pounds and is collecting at a rate of 8 pounds per hour this weekend. Javier collected 16 pounds earlier and Is now collecting at a rate of 12 pounds per hour. How many hours must pass (x) before the two students have collected the same amount of aluminum (y)?
Answer:
10 hoursStep-by-step explanation:
Victoria collects:
8x + 56Javier collects:
12x + 16They get same amount:
8x + 56 = 12x + 1612x - 8x = 56 - 164x = 40x = 10if f(x)= -5 -7x, find f(-2)
Answer:
Given f(-2)
= -5 -7(-2)
= -5+14
= 9
Thus f(-2) of f(x)= 5-7x is 9

I need to find the measure of angle A
Answer:
∠ A = 30°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
90 + x + 67 + x + 37 = 180, that is
2x + 194 = 180 ( subtract 194 from both sides )
2x = - 14 ( divide both sides by 2 )
x = - 7
Then
∠ A = x + 37 = - 7 + 37 = 30°
