Explanation:
____________________
Given:
____________________________
-2(5a − 3b²) − 4b + 3 ;
_________________________________
"Use the distributive property [of multiplication] to expand the expression."
______________________________________________
Note the distributive property of multiplication:
______________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
______________________________________________
So, we have: " -2(5a − 3b²) − 4b + 3 " ;
______________________________________________
Start with: " -2(5a − 3b²) " ;
______________________________________________
-2(5a − 3b²) = (-2*5a) − (-2*3b²) = (-10a) − (-6b²)
= -10a + 6b²
________________________________________________
→ Now, bring down the rest of the problem;
________________________________________________
-10a + 6b² − 4b + 3 ; which is: Answer choice: [B].

Answer: x = -2
<u>Step-by-step explanation:</u>
Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.
x² + 4x + 4 = 0
∧
1 + 4 = 5
2 + 2 = 4 <em>this works!</em> <em>so the factors are: </em>
(x + 2)(x + 2) = 0
x + 2 = 0 and x + 2 = 0
x = -2 and x = -2 --> <em>same answer so only need to list it once</em>
Answer:
B
Step-by-step explanation:
Hey There!
they are asking for the equation in slope intercept form
Slope intercept form is y=mx+b
where m equals slope and b equals y intercept
to find the slope we do change in y over chang in x
as y goes up 2 x goes down 5 so the slope would be -2/5
the y intercept is at (0,4) so the y intercept is 4
now we add everything together and get that the equation in slope intercept form is
y=-2/5x+4
so we can conclude that the answer is B
