are these lines perpendicular, parallel, or neither?
5x+3y=3 and 3x+5y=-25
Answer:
they are neither. if they were parallel they would be the same. if they were perpendicular they would be opposite reciprocal. So it is neither

Expand the brackets and simplify (2p + 3) (3p - 2)
Answer:
6p^2 + 5p - 6
Explanation
6p^2 - 4p + 9p - 6
6p^2 + (-4p + 9p) - 6
And then you would simplify your answer to that which would get you
6p^2 + 5p - 6

find the slope of the line PLEASE
Given the graph, we can determine the slope, and use slope formula* to prove it.
Points: (-4, 1) and (-2, -1)
From the graph, the slope of the line is -1, mean the line goes down 1 unit and left 1 unit.
To prove this you can use slope formula*:
[tex]m = \frac{-1 - 1}{-2 + 4} = \frac{-2}{2} = -1[/tex]
*Slope formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

A classroom has a length of 30 ft. and a width of 20 ft. The flooring is to be replaced by tiles. Each tile has a length of 36 in. and a width of 24 in. How much money will it cost to replace the tiles if each tile is $2.34? Please help!!
Answer:
You will encounter these area word problems often in math. ... If each tile has a length of 24 inches and a width of 36 inches, how many tiles are needed to fill the classroom? ... Area of classroom = length × width = 20 × 30 = 600 ft2 ... Learn about investing money, budgeting your money, paying taxes, mortgage loans
Step-by-step explanation:
Answer:
$234.00
Step-by-step explanation:
1. Find the area of the length of the classroom (L x W), to get 600ft.
2. Convert the area of 1 tile into feet. (Inches divided by 12)=3 Length & 2 Width, and get the area for 1 tile (L x W)=6
3.Divide size of classroom(Area), by the size of 1 tile (Area)=100, to get how many tiles they need to do the whole classroom.
4. We know that the cost for 1 tile $2.34, so do 2.34 times the amount of tiles they need (100), to get $234.00.

Answer:
[tex]-\frac{1}{6}[/tex]
Step-by-step explanation:
In order to find the answer to this question you must use order of operations and add after finding the common denominator.
[tex]-\frac{1}{2} +(\frac{3}{4} \times\frac{4}{9} )[/tex]
P goes first
[tex]\frac{3}{4} \times\frac{4}{9}[/tex]
Solve:
[tex]3\times4=12[/tex]
[tex]4\times9=36[/tex]
[tex]=\frac{12}{36}[/tex]
Reduce:
[tex]12\div6=2[/tex]
[tex]36\div6=6[/tex]
[tex]2\div2=1[/tex]
[tex]6\div2=3[/tex]
[tex]=\frac{1}{3}[/tex]
[tex]-\frac{1}{2} +\frac{1}{3}=\frac{-1\times3}{2\times3} +\frac{1\times2}{3\times2} =-\frac{1}{6}[/tex]
[tex]=-\frac{1}{6}[/tex]

numbered. The numbers of the first 5 students chosen are listed below.
21, 26, 31, 36, 41
What will be the number of the 111th student chosen?
Answer:
571
Step-by-step explanation:
The record low temperature recorded in Oklahoma was -31°F. The record low temperature in South Dakota is 27°F lower than -31°F. What is the record low in South Dakota?
I think its -58 ? Because its lower, so you'd subtract. -31 - 27 = -58
Sophie practices the piano 105 minutes in 1 week. If t represents the total time she practices for any number of days, d, write a proportional equation for t in terms of d that matches the context.
Answer:
t = 15dStep-by-step explanation:
You must first know that 1 week = 7days
If Sophie practices the piano 105 minutes in 1 week, this can be expressed as;
105 minutes = 7days
to calculate the total time t that she practices for any number of days, d, we will say;
t minutes = d days.
Solving both expression;
105 minutes = 7days
t minutes = d days.
Cross multiply;
7 * t = 105 * d
7t = 105d
Divide both sides by 7;
7t/7 = 105d/7
t = 15d
Hence a proportional equation for t in terms of d that matches the context is expressed as t = 15d
2.7x -9 = x +7.5 need the answer can't find solution.
Answer:
x = 9.7
Step-by-step explanation:
2.7x -9 = x +7.5
2.7x - x = 7.5 + 9
1.7x = 16.5
x = 16.5/1.7
x = 9.7
Answer:
x = 9.70588
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
2.7x - 9 = x + 7.5
Step 2: Solve for x
Subtract x on both sides: 1.7x - 9 = 7.5Add 9 on both sides: 1.7x = 16.5Divide 1.7 on both sides: x = 9.70588Step 3: Check
Substitute in x into the original equation to verify it's a solution.
Substitute in x: 2.7(9.70588) - 9 = 9.70588 + 7.5Multiply: 26.2059 - 9 = 9.70588 + 7.5Subtract/Add: 17.2059 = 17.2059Here we see that 17.2059 does indeed equal 17.2059.
∴ x = 9.70588 is a solution of the equation.

Iced out my wrist, It turned to water like its Fiji. I just traveled out of states, maybe to Tahiti. I'm in Dubai with the gang, getting with the bae, she please me. I slap 5 on top of my tints so you can't see me. I roll up my wrist OK, don't know if ima make it. But ima ball like I'm playing 2k. I know I'm on top, my mama taught me to never be less than great. I hang with animals like gorillas, no snakes, maybe some apes. I know I'm the hero of my hood, might as well hand me a cape.
You think a snake and a dog is the same thing. This a rollie up on my wrist, a bust down no plain jane. I only got three friends so you can't tell me you gang gang. I was all in the deep end so you can't tell me that you my main thing, like no. I had my hands against the wall, I told all my dogs I got they back, just gimme a call. I stand on 10 toes, I can't stand on one, I start to fall. Your love keep loving me, can't end up on my own. But you knew that It ain't no 20's in my stack because that's green, I got the blue pack. My life is hard work, I gotta make it, I can't cool back. My life is a movie, got a groupie and she so bad.

Answer:
36, 8.5
Step-by-step explanation:
an exponent of two means that you are multiply a number by itself
so in this case you would multiply 6 by itself: 6 x 6
this gets you 36
and 8.5 doesn't change so its just 8.5

The slope of a line passing through points (1, 2) and (1, 3) is equal to:
HELPPP
Answer:
Undefined.
Step-by-step explanation:
m = y2-y1 / x2-x1
m = 3 - 2 / 1 - 1
m = 1/0, which is undefined.
You can also tell because (1,2) and (1,3) is a vertical line, which means the slope is undefined.
the difference between 13 fours and 6 fours
Answer:
The lesson activity requires students to use up to four fours and any operation to make the numbers from 0 to 100. For example, 4 + 4 + 4 + 4 = 16.
Initially, students will use the more familiar operations, +, −, ×, ÷, along with brackets to create their equations. For example, (4 × 4 + 4) ÷ 4 = 5. Gradually, finding solutions for the remaining numbers in the list becomes more challenging. Here, it is a good opportunity to introduce some other operations to the students, including √4 = 2 and 4! = 24. In my experience, at least one student in the class will be familiar with the square root operation √n, which will make it easier to introduce. The other operation n!, known as factorial, will be less familiar to students.
n! is the product of all positive integers less than or equal to n; for example, 4! = 4 × 3 × 2 × 1 = 24, or 3! = 3 × 2 × 1 = 6
With the introduction of these two less familiar operations, the number of solutions that students can find to the initial problem increases.
