Y = 3x - 14. use expression y = mx+b where m is slope (use formula for finding slope between any two coordinates) and b is the y intercept, which u can find by using y = mx+b as well and plugging in values

Breann solved the system of equations below. What mistake did she make in her work?

mihalych1998 [28]

If 2x+y=5, then y=5-2x, so she substituted correctly.
x+4x=5x, so she combined like terms correctly.
She didn't subtract 10 from both sides, she added 10 to both sides.

Check the solution:
$2x+y=5 \hbox{ and } x-2y=10 \\
2 \times 4-3=5 \hbox{ and } 4-2 \times (-3)=10 \\
8-3=5 \hbox{ and } 4+6=10 \\
5=5 \hbox{ and } 10=10 \\
\checkmark$

The answer is: She made no mistake.

daniiel is currently 26 years older than his son. in 6 years he will be three times older than his son. how old are both of them

Molodets [167]

Answer:

Daniiel is 33 years old.

The son is 7 years old.

Step-by-step explanation:

x+26=3x

The x represents the son.

To solve for x:

-26=x-3x

-26=-2x

x=13

Since the father will be 3 times his son's age in six years we subtract 6.

x=7

This means the son is 7 years old as of right now. To find the father's age you do 7+26=33
