Answer:
x = 5
, y = 3
Step-by-step explanation:
Solve the following system:
{3 x + 4 y = 27 | (equation 1)
5 x - 3 y = 16 | (equation 2)
Swap equation 1 with equation 2:
{5 x - 3 y = 16 | (equation 1)
3 x + 4 y = 27 | (equation 2)
Subtract 3/5 × (equation 1) from equation 2:
{5 x - 3 y = 16 | (equation 1)
0 x+(29 y)/5 = 87/5 | (equation 2)
Multiply equation 2 by 5/29:
{5 x - 3 y = 16 | (equation 1)
0 x+y = 3 | (equation 2)
Add 3 × (equation 2) to equation 1:
{5 x+0 y = 25 | (equation 1)
0 x+y = 3 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 5 | (equation 1)
0 x+y = 3 | (equation 2)
Collect results:
Answer: {x = 5
, y = 3
Answer:
A, B, and E.
Step-by-step explanation:
A. 5^x * 5^x
= 5^x+x
=5^(2)(x)
=25^x
B. 5^2x
=5^(2)(x)
=25^x
C. 5*5^2x
=5^1+2x
D. 5*5^x
=5^1+x
E. (5*5)^x
=5^x*5^x
=5^(2)(x)
=25^x
F. 5^2*5^x
=5^2+x
Answer:
The answer to your question is 2 or (2, 0)
Step-by-step explanation:
Data
slope = m = 4
y-intercept = -8
Process
1.- Write the equation of the line in the slope y-intercept
y = mx + b
In this equation:
m = slope
b = y-intercept
-Substitution
y = 4x - 8
2.- To find the x-intercept, consider that y = 0 and solve for x.
0 = 4x - 8
4x = 8
x = 8/4
x = 2 or (2, 0)
Answer:
( a ) Trinomial, the degree of the polynomial = 3
( b ) Polynomial, the degree of the polynomial = 4
( c ) Binomial, the degree of the polynomial = 2
( d ) Monomial, the degree of the polynomial = 1
