Answer:

one solution: (-1,1)

Step-by-step explanation:

we have

$y=x+2$ ----> equation A

$6x-4y=-10$ ----> equation B

Solve the system by substitution

Substitute equation A in equation B

$6x-4(x+2)=-10$

solve for x

$6x-4x-8=-10$

$6x-4x=-10+8$

$2x=-2$

$x=-1$

Find the value of y

$y=x+2$ ----> $y=-1+2=1$

The solution is the point (-1,1)

therefore

one solution: (-1,1)

Answer:

Step-by-step explanation:

x_0=0

x_1 = $40

so delta change is $40. Now we can write the equation as

y = 40x, where y is the total saving account amount.

So after the 6th deposit, her total saving is $240.

y = 40(6) => 240

8x - 11 = -2x + 15 -5. What steps would you take to solve this?

MAVERICK [17]

Combine like terms. So that means combine the X's and combine the regular numbers.

- add 2x to 8x
- combine +15 -5
- then add 11 to that
- once you're done, find X by dividing 10x by whatever you have after the = sign

I need help with geometry I know its not the first one

alukav5142 [94]

Answer: ASA, C

Step-by-step explanation:

I think it's ASA cuz since the lines indicate they are parallel, then you can find that the two interior angles are also congruent. Since two angles are the same with the side inbetween being the same, it's probably asa.

Answer:

Step-by-step explanation:

Given,

Cost price of the car when Arjun bought = ₹ 3,50,000

Cost price of that same car after 1 year = ₹ 3,70,000

So,

Amount of money increased on the car's price

= ₹ (3,70,000 - 3,50,000)

= ₹ 20,000

Therefore, 

Percentage of increase on the car's price

$= \frac{20000}{350000} \times 100$

[On Simplification]

$= \frac{2}{35} \times 100$

[On further Simplification]

= 5.7142......

= 5.71 (approx.)

Hence,

Percentage in increase of car's price was 5.71% (Ans)
