____________
A) (-6,7,14)
B) (2,-3,5)
C) infinite solutions
D) no solutions

Answers

Answer:

D- No solution

Step-by-step explanation:

Isolate x for x+2y−z=3: x=3−2y+z

then Simplify

then Isolate y for −5y+4z+6=6: y= 4z 5 −5y+4z+6=6 Subtract 6 from both sides −5y+4z+6−6=6−6 Simplify −5y+4z=0 Subtract 4z from both sides −5y+4z−4z=0−4z Simplify −5y=−4z Divide both sides by −5 −5y −5 = −4z −5 Simplify y= 4z 5

Find the lateral area of the cylinder.

Answers

Answer:

[tex]A=440\ m^2[/tex]

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 10 m

Hight, h = 14 m

Radius, r = d/2 = 5 m

We need to find the lateral area of the cylinder. The formula for the lateral area of the cylinder is given by :

[tex]A=2\pi rh\\\\A=2\times \dfrac{22}{7} \times 5\times 14\\A=440\ m^2[/tex]

So, the lateral surface area of the cylinder is equal to [tex]440\ m^2[/tex].

What number should be added to both sides of the equation to complete the square?
x2 - 6x = 5

Answers

Answer:

Ans: 9

pls mark as brainliest!!

Step-by-step explanation:

Completing the square is done as follows:

1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.  

x^2 – 6x = 5

2. Make sure that the coefficient of the x^2 term is 1.

x^2 – 6x = 5

3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.

x^2 – 6x + 9 = 5 + 9

(x-3)^2 = 14

Therefore, 9 should be added to both sides to complete the square.

What is the simplified value of the expression below?

Answers

Answer:

I dont know the experssion but I will give you steps to figure it out!

Step-by-step explanation:

Before you evaluate an algebraic expression, you need to simplify it. This will make all your calculations much easier. Here are the basic steps to follow to simplify an algebraic expression:

remove parentheses by multiplying factors

use exponent rules to remove parentheses in terms with exponents

combine like terms by adding coefficients

combine the constants

When simplifying an expression, the first thing to look for is whether you can clear any parentheses. Often, you can use the distributive property to clear parentheses, by multiplying the factors times the terms inside the parentheses. In this expression, we can use the distributive property to get rid of the first two sets of parentheses.

Now we can get rid of the parentheses in the term with the exponents by using the exponent rules we learned earlier. When a term with an exponent is raised to a power, we multiply the exponents For example, (x2)2 becomes x4.

The next step in simplifying is to look for like terms and combine them. The terms 5x and 15x are like terms, because they have the same variable raised to the same power

Finally, we look for any constants that we can combine.

Now our expression is simplified. Just one more thing -- usually we write an algebraic expression in a certain order. We start with the terms that have the largest exponents and work our way down to the constants. Using the commutative property of addition, we can rearrange the terms and put this expression in correct order, like this.

Drag and drop number tiles into the boxes to show the median, first quartile (Q1) and third quartile (Q3)
of the data on the dot plot.

Answers

Answer:

Median = 5

Q1 = 2

Q3 = 10

Step-by-step explanation:

✔️On the dot plot, each dot represents a data point.

The median is the middle data point which is the 6th data point on the dot plot.

This:

Median = 5 (6th data point)

✔️Q1 is the middle value of the lower set of data points before the median = the 3rd data point

The 3rd data point is 2

Therefore,

Q1 = 2

✔️Q3 is the middle value of the upper set of data points after the median = the 9th data point.

The 9th data point = 10

Therefore,

Q3 = 10
