List all integers between −100 and 100 that are congruent to −1 modulo 25.

777dan777 [17]

"-1 modulo 25" is "1 less than a precise multiple of 25".
So what are the exact or precise multiples of 25 in the appropriate interval?
It is -75, -50, -25, 0, 25, 50, 75, and 100.
Now just subtract 1 from each of them.

So the answers are -76, -51, -26, -1, 24, 49, 74, and 99.

Solve the following equation: |-3x+3|-9=12

photoshop1234 [79]

Answer:

$\large\boxed{\left \{ {{x\: = \: 8} \atop {x\: =\: -6}} \right. }\\$

Step-by-step explanation:

$\left| -3x+3 \right| -9=12$

At first, let's add - 9 to both the sides. So,

$\left| -3x+3 \right| -9=12\\|-3x+3|=21$

Now, using the definition of absolute value, we can change the equation to..

$-3x+3=21 \\-3x+3=-21$

By, subtracting 3 from both the sides,

$-3x=18 \\-3x=-24$

Now, divide both the sides by 6,

$x=-6 \\x=8$

We now have 2 values of x. They are...

$\large\boxed{\left \{ {{x\: = \: 8} \atop {x\: =\: -6}} \right. }\\$
