Answer:

x>-2

Step-by-step explanation:

First you have to subtract 2 from both sides, which leaves you with -3x=6, then you have to divide -3 on both sides to get the variable by itself. Which is x<-2, but you have to switch the sign because you multiplied/divided by a negative number, then you get left with x>-2........Hope that helped!!!!!!!!!!:)

The sum of two numbers is 62, and their difference is 8. What are the numbers

Lemur [1.5K]

Sum of two numbers is 62?
Let's call the two numbers $a$ and $b$

let's find two same numbers that would add up to 62: 31.
31 + 31 = 62

since it said the difference is 8, we have to add 4 to one number and subtract 4 from another.
31 - 4 = 27
31 + 4 = 35

Therefore, the two numbers following the given rules are 27 and 35

Any of y'all understand how do do any of this?

Luda [366]

Answer:

10.) 12 + 3i

11.) 3 - i

A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y.

12.) x² - 8x + 17 = 0

Let's solve your equation step-by-step.

x² − 8x + 17 = 0

Step 1: Use quadratic formula with a=1, b=-8, c=17.

x= −b±√b2−4ac / 2a

x= −(−8) ± √(−8)2−4(1)(17) / 2(1)

x= 8 ± √−4 / 2

There are no real solutions.

13.) x²- 8x + 17 = 0

Let's solve your equation step-by-step.

x² − 8x + 17 = 0

Step 1: Use quadratic formula with a=1, b=-8, c=17.

x= −b ± √b2−4ac / 2a

x= −(−8) ± √(−8)2−4(1)(17) / 2(1)

x= 8 ± √−4 / 2

There are no real solutions.

Step-by-step explanation:

To solve a quadratic equation by factoring,

Put all terms on one side of the equal sign, leaving zero on the other side.

Factor.

Set each factor equal to zero.

Solve each of these equations.

Check by inserting your answer in the original equation

Alborosie

Answer:

Step-by-step explanation:

Median is the dot near the middle of each box. Since median of team one is to the left of that of team 2,

Team 1 has a lesser median than Team 2.

InterQuartile Range (IQR) is the length of the box, so

Team 1 has a bigger IQR than Team 2.
