Answer:
for a. you will first solve 5x²-2x+6 with
x=-b ± ✓b²-4ac
----------------
2a
then put the two answers you will get into a bracket then multiply it with 1/2x - 1\4
then write in form of dis :- A ×10^n
Step-by-step explanation:
b. the two products are not the same
Answer:
C
Step-by-step explanation:
Given
+ 
← factor the denominator of first fraction
= 
+
Multiply the numerator/ denominator of second fraction by (x + 2)
= + 
The denominators are now common, so add the numerators leaving the denominator, that is
= 
= 
→ with numerator 4x + 6 → C
4(c-d) is the answer bc the difference of (c-d) is done first, then multiplied by 4
Let's solve your system by substitution.
2x−2y=−4;2x+y=11
Rewrite equations:
2x+y=11;2x−2y=−4
Step: Solve2x+y=11for y:
2x+y=11
2x+y+−2x=11+−2x(Add -2x to both sides)
y=−2x+11
Step: Substitute−2x+11foryin2x−2y=−4:
2x−2y=−4
2x−2(−2x+11)=−4
6x−22=−4(Simplify both sides of the equation)
6x−22+22=−4+22(Add 22 to both sides)
6x=18
6x/6 = 18/6
(Divide both sides by 6)
x=3
Step: Substitute3forxiny=−2x+11:
y=−2x+11
y=(−2)(3)+11
y=5(Simplify both sides of the equation)
Answer:
x=3 and y=5
