2.26-30 3x+y=6
(0,_)
(_,0)
(3,_)
(6,_)
(5,_)
Answer:
Step-by-step explanation:
In ordered pairs (a,b) a is the x value and b is a y value.
if we have 3x+y=6
if x=0, y=6 --> (0,6)
if y=0, x=2 -->(2,0)
if x=3, y=-3--> (3, -3)
if x=6, y= -12 --->(6, -12)
if x=6, y= -9 ---> (5, -9)
PLEASE HELP ME ILL MARK BRAINLIEST !!!!! spam reported
Answer:
a) -4
b) +343
Step-by-step explanation:
a) 10 shares - loss $40
1 share --- ?
? = 40 / 10 = 4 decrease
b) each week 7 members increase for 49 weeks
so total increase = 7 * 49 = 343
9514 1404 393
Answer:
(a) -4 dollars
(b) +343 members
Step-by-step explanation:
(a) The change in the value of each share is the total amount of change divided by the number of shares:
change per share = (total change)/(number of shares)
change per share = (-40 dollars)/(10 shares) = -4 dollars/share
The change in value for each share was -4 dollars.
__
(b) As with most rate problems, the quantity is the product of rate and time.
growth = (7 members/week) × (49 weeks) = 7×49 members
growth = 343 members
The change in the club's size was +343 members.

Write a quadratic equation with 3/2 and 1/4 as its roots. Write the equation in the form ax2+bx+c=0, where a, b, and c are integers. PLEASE HELP AND SHOW ALL YOUR WORK ILL MARK BRAINLIEST
Answer:
8x^2 -14x +3 = 0
Step-by-step explanation:
The sum of the roots is (3/2) +(1/4) = (6/4 +1/4) = 7/4.
The product of the roots is (3/2)(1/4) = 3/8.
The quadratic can be written as ...
x^2 -(sum of roots)x +(product of roots) = 0
x^2 -7/4x +3/8 = 0
Multiplying by 8 makes all of the coefficients be integers:
8x^2 -14x +3 = 0

The length of a rectangular garden is 7 feet longer than its width. The garden's perimeter is 190 feet. Find the width of the garden.
Answer:
The width of the garden is 44 feet.
Step-by-step explanation:
A rectangular shape has 4 sides, so the perimeter would be x + x + y + y. We know that the total is 190 feet, and the length is 7 feet longer than the width.
Let x be the width of the rectangle.
Let y be the length of the rectangle; (y = x + 7)
Equation: 190 = x + x + y + y
190 = x + x + (x + 7) + (x + 7)
Combine like terms: 190 = 4x + 14
Find x: 190 - 14 = 4x, 176 = 4x, x = 44.
44 feet is the width of the garden.
Check: 44 + 44 + (44 + 7) + (44 + 7) = 190

What are the odds against choosing a green or red marble from a bag that contains two blue marbles, one green marble, seven white marbles, and four red marbles?
5:14
5:9
9:14
9:5
Answer:
Option #1 (5:14)
Step-by-step explanation:
The reason I chose option relies fully on these steps:
To find the ratio that represents the situation, you have to find the denominator of the fraction that the ratio itself represents:
5 : 14
9 : 5
To find this element you count the total number of objects that are in the problem:
2 + 1 + 7 + 4 = 14 total marbles to choose from - our denominator.
But what about the other number? That's our numerator, and we can find that by counting how many of the select possibilities - only counting the red and green marbles that may be chosen:
1 + 4 = 5
Therefore our denominator and numerator come together to form 5/14, which is equivalent to 5 : 14!
I hope this helped a bunch! Tell me if you need any further assistance...

What is the slope of this line?
Enter your answer as a whole number or a fraction in simplest form in the box.
9514 1404 393
Answer:
1/4
Step-by-step explanation:
The slope can be found using the slope formula with the two left-most marked points:
m = (y2 -y1)/(x2 -x1)
m = (6 -5)/(0 -(-4)) = 1/4
The slope of the line is 1/4.

Answer:
y = 2.5x
Step-by-step explanation:
Note where all the points are.
When x = 0, y = 0
When x = 2, y = 5
When x = 8, y = 20
You simply need to find how much "y" is for each "x". Divide y with x:
5/2 = 2.5
Check. Plug in the x, and obtain the y:
y = 2.5x
y = 2.5(4) = 10 (True).
y = 2.5(8) = 20 (True).

At which angle will the hexagon rotate so that it maps onto itself ?
Answer:
There are 6 angles between neighbour vertices, they all are equal (because a hexagon is regular) and their sum is 360°. Thus each angle has a measure of 360°/6=60°. Each subsequent rotation by 60° also maps a hexagon onto itself.

Step-by-step explanation:
Sally needs to have some drywall and insulation work done in her house. She has received a quote from a professional drywall contractor to complete her repairs for $1,200. Her neighbor Steve says he can complete the same job for $800. Sally could use a credit card to pay the contractor, but Steve can only accept cash. Sally’s credit card has a 14% APR for credit purchases and a 32% interest rate for cash advances. Expecting to pay $50 of the principle plus appropriate interest each month, Sally estimates that it would take her 24 months to pay off the contractor balance and 16 months to pay off the cash advance balance.
In the end, would it be cheaper for Sally to hire the contractor or her neighbor to complete the repairs
Answer:
gawain sa pagkatuto bilang 2 balikan ang awiting bayan ko sa pahina 15 hanapin ang mga simbolong pangmusika sa awiting guhit ang mga nakita mong simbolong pangmusika sa iyong kwaderno
Answer:
For $1,200 at 14% for 24 months, Sally would be have to pay $57.62 per month, or $1,382.88 after 24 months. Neighbor Steve: For $800 at 32% for 16 months, Sally would have to pay $62.08 per month or $993.28 after 16 months. Even with the (much) higher interest rate, Sally would pay $389.60 less if she went with Neighbor Steve. Even better is that the monthly payments would be about the same for the given timelines. Sally would still want to weight the benefits of contracted work vs. non-contracted work.

-2x + 2 < -8
Answer:
Step-by-step explanation:
x<-3
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality: 2*x-2-(-8)<0
1) Pull out like factors : 2x + 6 = 2 • (x + 3)
2) Divide both sides by 2
3) subtract 3 from both sides x<-3
