Answer:
D
You use algebra and solve it for y.
Step-by-step explanation:
4x-3y=18
3y=4x+18
y=4/3x +6
Answer: (2,7) (-2,-9) (3,11) (-3,-13)
Step-by-step explanation:
(2)(2)+(2)(2)-1 = 7
(2) (-2)+(2)(-2)-1 = -9
(3)(2)+(2)(3)-1 = 11
(-3)(2)+(2)(-3)-1 = -13
Answer:
The interest is $1080 and the amount is $4080.
Step-by-step explanation:
Find an interest by using the formula I=P*i*t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this examplee P = $3000, i = 6% and t = 6 years, so
I=P*i*t
I=3000*0.06*6
I=1080
The interest is 1080, therefore the total amount is 4080.
Hope this helps!
Answer:
1 hot dog costs $3.50
Step-by-step explanation:
Represent Hot dog with x and Hamburger with y
Gregory's purchase:
--- (1)
Hart's purchase:
---- (2)
Required
Find x
To do this, we'll make use of the elimination method of solving simultaneous equation.
Start by multiplying (1) by 2
2 * ()
This gives:
---- (3)
Subtract (2) from (3)
- ()
-------------------------
Solve for x
Hence:
1 hot dog costs $3.50
Answer:
Solution
A +B+C=180(Sum of angles of triangle )
A+90+52=180
A=180-(90+52)
A=38
Now,
Taking A as perpendicular
AC = Hypotenuse
BC=Perpendicular
BA= Base
