Solve this following system by graphing
X-y=4
X+y=2
Answer:
The answer is x = 3 and y = -1
Step-by-step explanation:
If you were to graph the two lines, their equations would be y = x - 4 and y = -x + 2. The two lines intersect at the point (3, -1), so the solution to the system is x = 3 and y = -1.

madison paid $53.58 in sales tax on her books. the sales tax was 8.6% of the cost of the books. how much did madison's books cost before tax?
Answer:
$48.98
Step-by-step explanation:
first move the decimal of your percent 2 places
8.6% = .086
then multiply by 53.58
.086 × 53 58= 4.60
subtract 4.60 from 53.58
53.58 - 4.60= 48.98

Answer:
See Explanation
Step-by-step explanation:
To do this, we will make use of the following rules:
Direct Variation: [tex]a\ \alpha\ b[/tex] => [tex]a = kb[/tex]
Inverse Variation: [tex]a\ \alpha\ \frac{1}{b}[/tex] ==> [tex]a = k/b[/tex]
Joint Variation: [tex]a\ \alpha\ bc[/tex] ==> [tex]a= kbc[/tex]
Direct, then inverse variation: [tex]a\ \alpha\ b\ \alpha\ \frac{1}{c}[/tex] ==> [tex]a= kb/c[/tex]
Having highlighted the rules, the solution is as follows:
1. m varies directly to a
[tex]m\ \alpha\ a[/tex]
[tex]m =ka[/tex]
2. p varies inversely as q.
[tex]p\ \alpha\ \frac{1}{q}[/tex]
[tex]p\ = k\frac{1}{q}[/tex]
3. [tex]r\ varies[/tex] directly as s and inversely as t.
[tex]r\ \alpha\ s\ \alpha\ \frac{1}{t}[/tex]
[tex]r = k\frac{s}{t}[/tex]
4. z varies jointly as [tex]e\ and\ f.[/tex]
[tex]z\ \alpha \ ef[/tex]
[tex]z = kef[/tex]
5. F varies directly as the [tex]square\ of\ t.[/tex]
[tex]F\ \alpha\ t^2[/tex]
[tex]F = kt^2[/tex]
6. d varies jointly r and t
[tex]d\ \alpha\ rt[/tex]
[tex]d = krt[/tex]
7. P is inversely proportional to h.
[tex]P\ \alpha\ \frac{1}{h}[/tex]
[tex]P= \frac{k}{h}[/tex]
8. P varies directly as V
[tex]P\ \alpha\ V[/tex]
[tex]P=kV[/tex]
9. d varies directly as the square of t
[tex]d\ \alpha\ t^2[/tex]
[tex]d = kt^2[/tex]
10. s varies jointly as b and d and inversely as the square L
[tex]s\ \alpha\ bd\ \alpha\ \frac{1}{L^2}[/tex]
[tex]s = k\frac{bd}{L^2}[/tex]
The translation of each statement to an equation using k as the constant of variation is
1. m varies directly to a.
m = k × a
m = ka
2. p varies inversely as q
p = k / q
3. r varies directly as s and inversely as t
r = (k × s) / t
r = ks / t
4. z varies jointly as e and f.
z = k × e × f
z = kef
5. F varies directly as the square of t.
F = k × t²
F = kt²
6. The distance (d) traveled by a car varies jointly as the rate (r) and the time (t) of travel.
d = k × r × t
d = krt
7. The air pressure (P) in inversely proportional to the altitude (h).
P = k / h
8. The amount of water pressure (P) in a closed container varies directly as the volume (V) of the
water.
P = k × V
P = kV
9. The distance (d) of a falling body varies directly as the square of the time (t) traveled.
d = k × t²
d = kt²
10. The stiffness (s) of a beam varies jointly as its breadth (b) and depth (d) and inversely as the
square of its length (L).
s = (k × b × d) / L²
s = kbd / L²

The half-life of helium-5 is 7.6 × 10-22 seconds, and the half-life of helium-9 is 7 × 10-21 seconds. Approximately how many times greater is the half-life of helium-9 than that of helium-5?
Answer:
Step-by-step explanation:
If 10-22 means 10⁻²², you need to use a ^ to indicate the exponent: 10^(-22)
(7×10⁻²¹)/(7.6×10⁻²²) = (7×10⁻²¹)/(0.76×10⁻²¹) = 7/0.76 ≅ 9.2

Arionna needed to graph triangle PQR reflected across the y-axis. Her work is shown below. Arionna’s Work: Blue right-arrow red. P (3,7) right arrow P prime (3, negative 7). Q (0, 4) right-arrow Q prime (0, 4). R (5, 8) right-arrow R prime (negative 5, 8). Arionna’s Graph On a coordinate plane, a red triangle has points (negative 7, 3), (negative 5, 8), (0, 4). A blue triangle has points (0, 4), (3, 7), (5, 8). Which statements identify her errors? Check all that apply. Arionna did not find the correct point for P’. She should have negated the x-value, not the y-value. Arionna did not find the correct value for Q’. All points in a reflection will move. Arionna did not find the correct value for R’. She should have negated the y-value, not the x-value. Arionna’s red triangle should be reflected below the horizontal axis rather than across the vertical axis. Arionna switched the order of the coordinates of P’ (3, –7) when she graphed them.
Answer:
A and E
Step-by-step explanation:
...
Arionna did not find the correct point for P’. She should have negated the x-value, not the y-value.
What is cartesian plane?A two-dimensional coordinate plane called the cartesian plane is what is created when the x- and y-axes cross. The origin is the place where the x-axis and y-axis meet perpendicularly.
A pair of perpendicular lines connect to create the cartesian plane, a two-dimensional coordinate plane. The term "Y-axis" refers to the vertical line, whereas "X-axis" refers to the horizontal line. The Cartesian coordinate point (x, y) indicates that the point's horizontal and vertical distances from the origin, respectively, are x and y, respectively. If x has a positive sign, the point will be to the right of the origin.
Given, Arionna needed to graph triangle PQR reflected across the y-axis.
Arionna’s Work:
Blue right-arrow red. P (3,7) right arrow P prime (3, negative 7). Q (0, 4) right-arrow Q prime (0, 4). R (5, 8) right-arrow R prime (negative 5, 8).
Reflection across y axis
(x , y) becomes ( - x , y)
P ( 3 , 7) P ' ( 3 , -7) The correct solution should have been ( -3 , 7),
Q ( 0 , 4) Q' ( 0 , 4) This is correct,
R (5 , 8) R' (-5 , 8) This is correct,
Arionna was unable to determine P's proper point. Not the y-value, but the x-value should have been negated instead.
The graph of Arionna
The points of a red triangle on a coordinate plane are (-7, 3), (-5, 8), and (0, 4).
When graphing P"s coordinates (3, -7), Arionna reversed their order.
A blue triangle has points (0, 4), (3, 7), (5, 8).
Hence Arionna Graph is attested in image.

Use complete sentences to describe the relationship between the two sets A and B if ACB.
Answer:
The relationship between the two sets A and B if A ⊆ B is A is subset of B
Step-by-step explanation:
A = {1,2,3,4,5}
B = {1,2,3,4,5,6,7,8}
All Elements of set A {1,2,3,4,5} are present in set B
we relate set A and set B as A ⊆ B,which means set A is subset of set B. Symbol “⊆” is used to denote subset
So set A is subset of set B (A ⊆ B)

A random sample of 362 married couples found that 286 had two or more personality preferences in common. In another random sample of 556 married couples, it was found that only 32 had no preferences in common. Let p1 be the population proportion of all married couples who have two or more personality preferences in common. Let p2 be the population proportion of all married couples who have no personality preferences in common.
A) Find a 95% confidence interval for p1 and p2.
B) Examine the confidence interval in part (a) and explain what it means in the context of this problem. Does the confidence interval contain all positive, a negative or both positive and negative numbers? What does this tell you about the proportion of married couples with three personality preferences in common compared with the proportion of couples with two preferences in common (at the 95% confidence level)?
1) Because the interval contains only positive numbers, we can say that a higher proportion of married couples have three personality preferences in common.
2) Because the interval contains both positive and negative numbers, we can not say that a higher proportion of married couples have three personality preferences in common.
3) We can not make any conclusions using this confidence interval.
4) Because the interval contains only negative numbers, we can say that a higher proportion of married couples have two personality preferences in common.
