Answer:
[tex]\huge\boxed{\sf y = 3}[/tex]
Step-by-step explanation:
Given that:
[tex]\displaystyle y \propto \frac{1}{x}[/tex]
Converting proportionality into equality
[tex]\displaystyle y = \frac{k }{x}[/tex] ------------------------- (1)
We know that:
y = 18 when x = 4
Put in Eq. (1)
[tex]\displaystyle 18 = \frac{k}{4} \\\\Multiply \ 4 \ to \ both \ sides\\\\18 \times 4 = k\\\\72 = k\\\\ \boxed{k = 72}[/tex]
Now,
y = ? when x = 24
Put in Eq. (1)
[tex]\displaystyle y = \frac{72}{24} \\\\\boxed{y = 3}[/tex]

Jan rewrote the expression ½y • 5 as 5 •½y Which property of operations did Jan use?
Answer:
Commutative property of multiplication
Step-by-step explanation:
Answer:
Jan is using commutative property.
Step-by-step explanation:
Commutative property is when you switch values and they don't make a change in the outcome.
Just remember, this only applies to addition and multiplication but does not apply to division or subtraction!!!
Examples:
2+4=6
4+2=6
9x3=27
3x9=27

Write the formula for the parabola that has x- intercepts (1.3.0) and (-1.3.0). and y - intercept (0.169)
From x- intercepts it was possible to find the formula of the parabola: x²-1.69=0.
Quadratic functionThe quadratic function can be represented by a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.
From the sum and product of the roots in a quadratic function it is possible to write your respective equation. Since:
S= sum of the roots (x1+x2) = [tex]-\frac{b}{a}[/tex]P= product of the roots (x1*x2)= [tex]\frac{c}{a}[/tex]This question gives the root since it informs the x- intercepts (1.3,0) and (-1.3,0). Then, the roots are: x1=1.3 and x2= -1.3.
Hence, you should write the equation in factors from the known roots. See: (x-1.3) * (x+1.3)=0. Multiplying the factor, you will have:
x²+1.3x-1.3x-1.69=0
x²-1.69=0
You can check the previous result from :
the sum of the roots (S) will be 1.3-1.3=0.
the product of the roots (P) will be 1.3*(-1.3)=-1.69.
So, the formula of the parabola is x²-1.69=0. The attached figure shows the x-intercepts and y-intercept informed.

Hunter thought he had 400 baseball cards, but he actually had 620. Calculate Hunter’s percent error.
With the actual ball the hunter had as 620 balls and the ball the hunter thought he had as 400 balls, The Hunter’s percentage error is mathematically given as
e=35.483%
What is Hunter’s percentage error?Question Parameters:
Hunter thought he had 400 baseball cards, but he actually had 620.
Generally, the equation for the error is mathematically given as
[tex]e=(\frac{false cards}{original card}*100)[/tex]
Therefore, if
False cards=620-200

Need help I’m suck on this problem
this is a sketch of the curve with equation y=f(X). The curve has a minimum point at M(-1,-3).
The minimum point of the function y=f(x)+3 is at (-1 , 0 ) .
The biggest and lowest value of a function, either inside a specific range (the local or relative extrema) or on the entire domain, are generally referred to as extrema (plural of extremum) in mathematical analysis (the global or absolute extrema). One of the first mathematicians to suggest the general method of adequacy for determining the maxima and minima of functions was Pierre de Fermat.
The maximum and minimum of a set are the greatest and least items in the set, as described by set theory. There are no minimum or maximum values in unbounded infinite sets, such as the set of real numbers.
Say that (x,y) = where y = f(x) minimum occurs at (-1,-3). As a result, for all other x inside its domain of definition, y= f(x) >=-3
y = f(x) + 3 simply elevates the graph of y by 3 and increases the value of y for any x. Its minimum x-value remains at -1, and its value for y is f(3) + 3 = -3 + 3 = 0. as a result, new minimum =(-1 , 0 ) .

What other information do you need in order to prove the triangles congruent using the SAS Congruence Postulate?
Answer:
Step-by-step explanation:
AC is perpendicular to BD.
Further explanation
We observe that both the ABC triangle and the ADC triangle have the same AC side length. Therefore we know that is reflexive.
The length of the base of the triangle is the same, i.e., .
In order to prove the triangles congruent using the SAS congruence postulate, we need the other information, namely . Thus we get ∠ACB = ∠ACD = 90°.
Conclusions for the SAS Congruent Postulate from this problem:
∠ACB = ∠ACD
- - - - - - - - - -
The following is not other or additional information along with the reasons.
∠CBA = ∠CDA no, because that is AAS with ∠ACB = ∠ACD and
∠BAC = ∠DAC no, because that is ASA with and ∠ACB = ∠ACD.

Notes
The SAS (Side-Angle-Side) postulate for the congruent triangles: two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle; the included angle properly represents the angle formed by two sides.
The ASA (Angle-Side-Angle) postulate for the congruent triangles: two angles and the included side of one triangle are congruent to two angles and the included side of another triangle; the included side properly represents the side between the vertices of the two angles.
The SSS (Side-Side-Side) postulate for the congruent triangles: all three sides in one triangle are congruent to the corresponding sides within the other.
The AAS (Angle-Angle-Side) postulate for the congruent triangles: two pairs of corresponding angles and a pair of opposite sides are equal in both triangles.
