Solve the following system of equations by the substitution method.

Mathematics
1 answer:
Dahasolnce [82]3 years ago
6 0

Answer:

Step-by-step explanation:

5x=y+6   --------- equ 1

2x-3y=4  -------- equ 2

5x - 6 = y

y = 5x - 6

substitute in equ 2

2x-3(5x - 6) =4

2x - 3*5x + 3*6 = 4

2x - 15x + 18 = 4

- 13x = 4 - 18

-13x = -14

x = -14/-13

x = 14/13

substitute  in equ 1

5*14/13 = y+6  

70/13 - 6 = y

y =  ( 70 - 78)/13

y = -8/13

Write an inequality that represents the graph
Scilla [17]

Answer:

y > 2x+1

Step-by-step explanation:

Find an equation of the line: slope = 2, y-intercept = 1, y = 2x + 1

Find a point in the shaded area of the graph to substitute into the equation: ex. (0, 2), substituted in, it becomes 2 = 1

Change the sign so 2 = 1 becomes true; 2 > 1

Implement that sign into the original equation, and because it is a dotted line, not a solid one, the sign will not include "or equal to"

y > 2x + 1

Which is the best estimate for the product of 1/3 * 11 and 3/4
FromTheMoon [43]
Tis very straightforwards, we simply multiply the numerators and denominators,

\bf \cfrac{1}{3}\cdot 11\cdot \cfrac{3}{4}\implies \cfrac{1}{3}\cdot \cfrac{11}{1}\cdot \cfrac{3}{4}\implies \cfrac{1\cdot 11\cdot \underline{3}}{\underline{3}\cdot 1\cdot 4}\implies \cfrac{1\cdot 11\cdot 1}{1\cdot 1\cdot 4}\implies \cfrac{11}{4}\implies 2\frac{3}{4}
