Answer: the domain is all real numbers. The Range is all real numbers greater than zero.
Step-by-step explanation:
this si the same as the graph y=5^-x. Which decreases from left to right and approaches but never touches the x-axis.
Solve for 1 variable
solve for x in second
add 2y to both sides
x=2y-5
sub 2y-5 for x in first equation
2(2y-5)-5y=-14
4y-10-5y=-14
-10-y=-14
add 10 to both sides
-y=-4
times -1
y=4
sub
x=2y-5
x=2(4)-5
x=8-5
x=3
x=3
y=4
(3,4)
Answer:
there is two terms. 3x^4 and 2y)^7

(2x+3y)⁴
1) let 2x = a and 3y = b
(a+b)⁴ = a⁴ + a³b + a²b² + ab³ + b⁴
Now let's find the coefficient of each factor using Pascal Triangle
0 | 1
1 | 1 1
2 | 1 2 1
3 | 1 3 3 1
4 | 1 4 6 4 1
0,1,2,3,4,.. represent the exponents of binomials
Since our binomial has a 4th exponents, the coefficients are respectively:
(1)a⁴ + (4)a³b + (6)a²b² + (4)ab³ + (1)b⁴
Now replace a and b by their real values in (1):
2⁴x⁴ +(4)8x³(3y) + (6)(2²x²)(3²y²) + (4)(2x)(3³y³) + (1)(3⁴)(y⁴)
16x⁴ + 96x³y + 216x²y² + 216xy³ + 81y⁴
10/3 is correct . 4(2x-3)-5x+2
