Write a quadratic equation could some please help asap
Answer:
f(x) = x^2 + 3x + 2.
Step-by-step explanation:
The zeroes of the quadratic function are -1 and -2 so we can write it as:
f(x) = a(x + 1)(x + 2) where a is some constant.
Now, when x = 1, f(x) = 6 so
6 = a(1+1)(1+2)
6 = a*2*3 = 6a
a = 1.
So the function is f(x) = (x + 1)(x + 2) = x^2 + 3x + 2.

Convert the decimal to a fraction in simplest form:
0.333
O 533/1000
1
O 333 —
10
1
O 3 —
333
O 333/1000
Answer:
Decimal 0.333 to a fraction in simplest form is: [tex]\frac{333}{1000}[/tex]
Step-by-step explanation:
Given the decimal
[tex]0.333[/tex]
Multiply and divide by 10 for every number after the decimal point.
There are three digits to the right of the decimal point, therefore multiply and divide by 1000.
Thus,
[tex]0.333=\frac{0.333\cdot \:\:1000}{1000}[/tex]
[tex]=\frac{333}{1000}[/tex] ∵ 0.333×1000 = 333
Let us check if we can reduce the fraction [tex]\frac{333}{1000}[/tex]
For this, we need to find a common factor of 333 and 1000 in order to cancel it out.
But, first, we need to find the Greatest Common Divisor (GCD) of 333, 1000
Greatest Common Divisor (GCD) :
The GCD of a, b is the largest positive number that divides both a and b without a remainder.
Prime Factorization of 333: 3 · 3 · 37
Prime Factorization of 1000: 2 · 2 · 2 · 5 · 5 · 5
As there is no common factor for 333 and 1000, therefore, the GCD is 1.
Important Tip:
As GCD is 1, therefore the fraction can not be simplified.Therefore, decimal 0.333 to a fraction in simplest form is: [tex]\frac{333}{1000}[/tex]
The variables a and b vary directly, and b=8 when a=2.
What is the direct variation equation that relates a and b?
A.
b=2a.
B.
b-4a
C
b=8a
D
b=16a
Answer: b= 4a
( This is the correct answer, which is supposed to be option b, but a negative sign was put instead of an equal sign, so you can change appropriately)
Step-by-step explanation:
Given that a and b vary directly, can be expressed as
a ∝ b
Introducing the constant of proportionality, k, we have that
a = kb
so when a= 2, b= 8 and the constant becomes
2 = k8
k = 2/8=1/ 4
a= 1/4b
Such that
b=4a
find find the slope and Y intercept of Y= 10x - 1/3
Answer:
slope: 10
y-intercept: -1/3
Step-by-step explanation:
slope-intercept form is y = mx + b where m = slope and b = y-intercept.
the equation you're given is y = 10x - 1/3, which just happens to be in slope-intercept form already and doesn't require you to solve for any unknown variables. all you have to do is identify the m (slope) value and the b (y-intercept) value! :)
let's begin by finding your equation's slope, which is represented by the variable m in slope-intercept form! keep in mind that slope-intercept form is y = mx + b.
y = 10x - 1/3
now we need to find your equation's y-intercept, which is represented by the variable b in slope-intercept form! again, keep in mind that slope-intercept form is y = mx + b.
y = 10x - 1/3
therefore, the slope is 10 and the y-intercept is -1/3. i hope this helps! have an amazing day <3

let f(x)=2x+3 and g(x)=x×x-1
find a. f(g(x)) b.g(f(x))
Answer:
See explanations below
Step-by-step explanation:
Given the functions f(x)=2x+3 and g(x)=x^2-1
a. Find f(g(x))
f(g(x)) = f(x^2-1)
f(g(x)) = 2(x^2-1)+3
f(g(x))= 2x^2-2+3
f(g(x)) = 2x^2+1
Hence the composite function f(g(x)) is 2x^2+1
b) g(f(x)) = g(2x+3)
g(f(x) = (2x+3)^2-1
g(f(x)) = 4x^2+12x+9-1
g(f(x)) = 4x^2+12x+8

I have 24$ to buy bagels. How does the number of bagels I can buy depend on the price of the bagels? Write a formula for the function. If the number of Bagels is N, and the price of the bagel is P, find out what N =.
Note: N is a natural number.
Answer:
N=24/P
The number of bagels(N) would be equal to 24$ divided by the price of the bagels. If there is a remainder, round down because you cannot buy pieces of bagels.
Step-by-step explanation:
If you have 24$ to buy bagels, the amount of bagels depends on the price amount. The price of the bagels could also be called the independent variable, while the amount of bagels you end up getting would be the dependent variable.
In the image you have a double line that shows that buying 2 bags of rice costs $ 3. How many bags can you buy with $ 12? and If I have $ 24, how many bags can I buy?
Answer:
Step-by-step explanation:
8 bags buy with $12
16 bags buy with $24
The coordinates of quadrilateral JKLM are: J: (1,-2) K: (13,4) L: (6,8) and M: (-2,4). Prove that JKLM is a trapezoid, but not an isosceles trapezoid
Answer:
of quadrilateral JKLM are: J: (1,-2) K: (13,4) L: (6,8) and M: (-2,4). Prove that JKLM is a trapezoid, but not an isosceles trapezoid
The required JKLM is a trapezoid, but as the two sides are equal so JKLM is an isosceles trapezoid.
What is a quadrilateral?A quadrilateral is a four-sided shape as given in the picture in question.
A quadrilateral is a trapezoid if exactly one pair of its opposite sides are parallel. To prove that JKLM is a trapezoid, we can find the slopes of its sides and check if exactly one pair of opposite sides have the same slope. The slope of a line passing through points (x₁, y₁) and (x₂, y₂) is given by (y₂ - y₁) / (x₂ - x₁).
The slope of JK is (4 - (-2)) / (13 - 1) = 6 / 12 = 1/2
The slope of KL is (8 - 4) / (6 - 13) = 4 / (-7) = -4/7
The slope of LM is (4 - (-2)) / (-2 - 6) = 6 / -8 = -3/4
The slope of MJ is (-2 - 4) / (1 - 13) = -6 / -12 = 1/2
Since JK and LM have different slopes, we can conclude that exactly one pair of opposite sides are parallel; thus, JKLM is a trapezoid.
To prove that JKLM is not an isosceles trapezoid, we need to show that none of its sides have equal length. The distance between two points (x₁, y₁) and (x₂, y₂) can be calculated using,
The distance formula = √((x₂ - x₁)² + (y₂ - y₁)²)
We can calculate the lengths of all four sides of JKLM and see if any of them are equal.
JK = √((13 - 1)² + (4 - (-2))²) = √(144 + 36) = √(180) = 6√(5)
KL = √((6 - 13)² + (8 - 4)²) = √(49 + 16) = √(65) = √65
LM = √((-2 - 6)² + (4 - (-2))²) = √(64 + 36) = √(100) = 10
MJ = √((1 - 13)² + (-2 - 4)²) = √(144 + 36) = √(180) = 6√(5)
Since two of the four sides are equal in length, JKLM is an isosceles trapezoid.

Sandra bought 4 pounds of sweet potatoes for $6.28. What is the cost per pound of the sweet potatoes?
Answer:
Cost of 1 sweet potato is $6.28 divided by 4 which will give $1.75
Answer:
$1.57
Step-by-step explanation:
What we know:
- There are 4 pounds of sweet potatoes
- 4 pounds of sweet potatoes cost $6.28
To find the cost per pound of sweet potatoes, divide $6.28 by 4.
6.28 ÷ 4
= $1.57
Therefore, the cost per pound of sweet potatoes is $1.57.

Answer:
Okay to start with we know this side isn't congruent to our side with 55 degrees looking at this side we can see that x is not 95 degrees because it is an acute angle so A is crossed out. Next this side isn't congruent like I said so B is crossed out. C is possible but the angle wouldn't be as wide as it is if we had 59 degrees so C is incorrect. Leaving us with D 70 degrees hope this helps and sorry if I got it wrong!

using gcf
Answer: the gcf is 5
Step-by-step explanation:
The Greatest Common Factor for the equation 90y + 65z is 5.
What is Greatest Common Factor?The largest number among all the common factors of the given numbers is known as the GCF (Greatest Common Factor) of two or more numbers. The greatest integer that may be used to divide two natural numbers x and y without producing any remainder is called their GCF.
Given the equation 90y + 65z
where y and z are variables,
to find the GCF of the equation,
factors of 90 are 2 x 3 x 3 x 5
factors of 65 are 5 x 13
substitute the value of 90 and 65
equation is 2 x 3 x 3 x 5y + 5 x 13z
5(18y + 13z)
Hence GCF of the equation is 5.
