A car traveled 140 miles in 2 hours. at this rate, how many miles will the car travel in 5 1/2 hours?
You just multiply
Answer:
<h2>not exist</h2>
Step-by-step explanation:
The coordinates of the intersection of the line are the solution of the system of equations.
The system of equations has no solution. Therefore, the lines are parallel (the intersection does not exist).
Answer:
The Answer is D : In triangle EFG△ , if EH=HF and EI=IG , then HI= 1/2 FG

Step-by-step explanation:
3a²-7a−6
Factor the expression by grouping. First, the expression needs to be rewritten as 3a
2
+pa+qa−6. To find p and q, set up a system to be solved.
p+q=−7
pq=3(−6)=−18
Since pq is negative, p and q have the opposite signs. Since p+q is negative, the negative number has greater absolute value than the positive. List all such integer pairs that give product −18.
1,−18
2,−9
3,−6
Calculate the sum for each pair.
1−18=−17
2−9=−7
3−6=−3
The solution is the pair that gives sum −7.
p=−9
q=2
Rewrite 3a
2−7a−6 as (3a
2−9a)+(2a−6).
(3a 2−9a)+(2a−6)
Factor out 3a in the first and 2 in the second group.
3a(a−3)+2(a−3)
Factor out common term a−3 by using distributive property.
(a−3)(3a+2)
U can use math. way for this
