Answer: x=-7/9, y=4/3. (-7/9, 4/3).

Step-by-step explanation: 6x+2y=-2

3x-2y=-5

-----------------

9x=-7

x=-7/9

6(-7/9)+2y=-2

-42/9+2y=-2

2y=-2-(-42/9)

2y=-2+42/9

2y=-18/9+42/9

2y=24/9

y=(24/9)/2

y=(24/9)(1/2)

y=24/18

y=4/3

Which value satisfies the inequality 3x+10-2x<-4x+45
anygoal [31]

First to answer

Answer:

x<7

Step By Step Answering:

Step 1: Simplify both sides of the inequality.

x+10<−4x+45

Step 2: Add 4x to both sides.

x+10+4x<−4x+45+4x

5x+10<45

Step 3: Subtract 10 from both sides.

5x+10−10<45−10

5x<35

Step 4: Divide both sides by 5.

5x/5<35/5

x<7

Mai's younger brother tells her that 10/7 is equal to square root of 2. Mai knows this can't be right,
Kryger [21]

Answer:

10/7 is a simple fraction, and √2 cannot be written as a simple fraction. So, they are not the same.

Step-by-step explanation:

10/7 is a number that has a numerator and a denominator.

Suppose √2 = 10/7, then √2 can also be written as a number that has a numerator and a denominator.

Since this is not the case, 10/7 cannot be the same as √2.

Elza [17]

A function assigns the values. The value a is 11.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The given logarithmic function can be solved as shown below.

(\log(a-1))^2 =\log10\\\\(\log(a-1))^2 =1\\\\(\log(a-1)) =\sqrt1\\\\\log(a-1) = 1\\\\10^1 = a-1\\\\a = 11

Hence, the value a is 11.
