Answer:
5y + 2y - 4x + 4x = -7 +14
7y = 7
y = 1
2(1) + 4x = 14
4x = 12
x = 3
Step-by-step explanation:
Using the process of elimination
Add both equations. The 4x will be eliminated since one is positive and one is negative. The equation is left with only the y variable and the constant.
When y is found, input it into the second equation to find x.
<span>I = PRT
</span><span>P = 1000
R = 2.5% -- change to a decimal = .025
T = 3
</span>
<span>
now we sub
I = PRT
I = (1000)(.025)(3)
I = 75
</span><span> so at the end of 3 years, there will be : 1000 + 75 = $ 1075 in the account
</span>
Hope this helps!!

Answer:
≈13degrees
Step-by-step explanation:
It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,
Using the formula, 
where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get
⇒
Therefore, 
⇒
⇒
Thus, the latitude of B is=12.53 degrees≈13degrees

Answer:
y = 2x - 3
Step-by-step explanation:
Slope intercept equation of a line:
y = mx + b
(0, -3) is the y-intercept, so b = -3
We have
y = mx - 3
Now we use the two points to find the slope.
slope = m = (-3 - 5)/(0 - 4) = -8/(-4) = 2
y = 2x - 3
