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
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.

How many lumps of wax 2½ cm by 2 cm by 1 cm can be cut from a block 25 cm by 20 cm by 15 cm?
Step-by-step explanation:
first the theoretical maximum number :
the big block is 25cm×20cm×15cm.
so, the volume is 25×20×15 = 7500 cm³
we want to cut this note into pieces of 2.5cm×2cm×1cm with a volume of 2.5×2×1 = 5 cm³
so, we can get 7500/5 = 1500 such lumps out of the big block.
now, a quick check, if we can cut full pieces until the last bit, or if the shape of the big block will not allow us to fully cut it into the desired pieces, and we get some remains (too small to be lumps of the desired size and shape).
and we do this by checking, if each dimension of the big block can be divided by the dimensions of the small lumps without remainder (whole number results).
25 / 2.5 = 10, and no remainder here.
=> 10 cuts of 2.5 cm perpendicular to the length.
20 / 2 = 10, and no remainder here.
=> 10 cuts of 2cm perpendicular to the width.
15 / 1 = 15, and no remainder here.
=> 15 cuts of 1 cm perpendicular to the height.
so, yes, we can achieve the theoretical maximum number of 1500 lumps also in reality and cut the big block without remaining material into these small blocks.

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).

Simplify: 7p + 20 – 13q – 4q – 18 + 6p A. 13p + 17q – 2 B. 13p – 17q + 2 C. 3q + 38 D. 3q – 6
Answer:
13p - 17q + 2 (Option B)
Step-by-step explanation:
[tex]7p + 20 - 13q - 4q - 18 + 6p[/tex]
Step 1) Arrange all like terms.
[tex] = > (7p + 6p) + ( - 13q - 4q) + (20 - 18)[/tex]
Step 2) Add/substract all those like terms and you're done.
[tex] = > 13p - 17q + 2[/tex]
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 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.
solve the inequality for x
-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

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)

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!

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 function rule for the given situation. Give both the algebraic rule and the function rule.
Answer:
[tex]y=20x[/tex]
We know that the slope is 20 in this situation, as we can tell that 20 gallons are used every time the dishwasher is ran, therefore, everytime y increases by 1, x will increase by 20. Since the problem starts at the origin (0, 0), there is no y-intercept, so we don't have to worry about that.
