Answer: A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.
Step-by-step explanation:
A system of linear inequalities can be written as:
y < a*x + b
y < c*x + d
or
y ≤ a*x + b
y ≤ c*x + d
In the first case, the borders are not included in the solutions, and in the second case, the borders are included.
Where the solutions will be points like (x, y), where these points must be solutions for both inequalities.
Then the only option that is correct for a general system of inequalities is:
A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.
Answer:
A solution of a system of linear inequalities is an ordered pair that satisfies at least one of the inequalities in the system.A solution of a system of linear inequalities is an ordered pair that satisfies the intersection of the border of each inequality.A solution of a system of linear inequalities is an ordered pair that satisfies neither inequality in the system.A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.

What is the image point of (-5,3) after a translation left 3 units and down 1 unit?
Answer:
(- 8, 2 )
Step-by-step explanation:
A shift of 3 left means subtract 3 from the x- coordinate
A shift of 1 down means subtract 1 from the y- coordinate
Translation rule is
(x, y ) → (x - 3, y - 1 ), thus
(- 5, 3 ) → (- 5 - 3, 3 - 1 ) → (- 8, 2 )

Answer:
decimal form: 7.46410161 or the exact form: x = 4 + 2 √ 3
Step-by-step explanation:
Answer:
4 + 2√3
Step-by-step explanation:
x - 2 = √4x
Domain: √4x ≥ 0 ⇒ x - 2 ≥ 0 ⇒ x ≥ 2
(x - 2)² = (√4x)²
x² - 4x + 4 = 4x
x² - 8x + 4 = 0
D = (- 8)² - 4(1)(4) = 48 = (4√3)²
[tex]x_{1}[/tex] = [tex]\frac{8+4\sqrt{3} }{2}[/tex] = 4 + 2√3 ≈ 7.4641
[tex]x_{2}[/tex] = [tex]\frac{8-4\sqrt{3} }{2}[/tex] = 4 - 2√3 ≈ 0.5359 < 2 ⇒ [tex]x_{2}[/tex] is extraneous root

Answer:
(1,1) and (7,5) => Slope: 2/3
(1,1) and (5,7) => Slope: 3/2
(2,5) and (-1,2) => Slope:1
(2,5) and (-7,-4) => Slope:1
Step-by-step explanation:
The slope of a line is denoted by m and is given as:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Calculating the slope one by one for each pair.
(1,1) and (7,5):
Let m1 be the slope of this line
Here
(x1,y1) = (1,1)
(x2,y2) = (7,5)
Putting values in formula
[tex]m_1 = \frac{5-1}{7-1}\\= \frac{4}{6}\\=\frac{2}{3}[/tex]
(1,1) and (5,7):
Let m2 be the slope of this line
Here
(x1,y1) = (1,1)
(x2,y2) = (5,7)
Putting values in formula
[tex]m_2 = \frac{7-1}{5-1}\\m_2=\frac{6}{4} = \frac{3}{2}[/tex]
(2,5) and (-1,2):
Let m3 be the slope of this line
Here
(x1,y1) = (2,5)
(x2,y2) = (-1,2)
Putting values in formula
[tex]m_3 = \frac{2-5}{-1-2}\\m_3 = \frac{-3}{-3} = 1[/tex]
(2,5) and (-7,-4):
Let m4 be the slope of this line
Here
(x1,y1) = (2,5)
(x2,y2) = (-7,-4)
Putting values in formula
[tex]m_4 = \frac{-4-5}{-7-2}\\m_4 = \frac{-9}{-9} = 1[/tex]
Hence,
The points and their respective slopes are as follows:
(1,1) and (7,5) => Slope: 2/3
(1,1) and (5,7) => Slope: 3/2
(2,5) and (-1,2) => Slope:1
(2,5) and (-7,-4) => Slope:1

givin the standard form for a trinomial ax^2+bx+c, and factored form (px+r)(qx+s) match the following:
a=
b=
c=
to
(p*s)+(q*r)
r*s
p*q
Answer:
[tex]a = p*q\\b = (p*s)+(q*r)\\c = r*s[/tex]
Step-by-step explanation:
We are given the standard form of trinomial
[tex]ax^2+bx+c[/tex]
After factorization, the form is:
[tex](px+r)(qx+s)[/tex]
We have to compare the factored form and the standard form to find the values of a,b and c in terms of p,q,r and s. For this purpose, the factored form will be converted into standard form.
Multiplying the both factors
[tex](px+r)(qx+s)\\=px(qx+s)+r(qx+s)\\= pqx^2+psx+qrx+rs\\= pqx^2+(ps+qr)x+rs[/tex]
Comparing both forms with each other
After comparing
[tex]a = pq = p*q\\b = ps+qr = (p*s)+(q*r)\\c = rs = r*s[/tex]
Hence,
[tex]a = p*q\\b = (p*s)+(q*r)\\c = r*s[/tex]
Classify each function as linear or nonlinear.
Step-by-step explanation:
Linear:
4x - y = 3
-6x = 3y - 17
x = y/5
non linear:
(x/2)^2 + 1 = y
y/x^2 = 4
2x^2 = 12 - 8y

The triangle ΔABC is similar to the triangle ΔADE. Then the value of the variable 'x' will be 4 units.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
The triangle ΔABC is similar to the triangle ΔADE. Then the ratio of the corresponding sides will be constant. Then the equation is given as,
2 / (2 + x) = 1 / 3
Simplify the equation, then we have
2 / (x + 2) = 1 / 3
6 = (x + 2)
x = 6 - 2
x = 4
The value of the variable 'x' will be 4 units.

The value of sin35∘ is equivalent to which value?
A. cos65∘
B. cos55∘
C. cos90∘
D. cos45∘
Answer:
B
Step-by-step explanation:
We can use the following co-function identity:
[tex]\sin(x)=\cos(90-x)[/tex]
Substuting 35 for x yields:
[tex]\sin(35)=\cos(90-35)[/tex]
Subtract:
[tex]\sin(35)=\cos(55)[/tex]

Answer:
(a) after 5 minutes: tower 1 -- 1550 gallons; tower 2 -- 670 gallons
(b) 1650-20m = 570+20m; m = 27 . . . minutes
Step-by-step explanation:
(a) At the rate of 20 gallons per minute, in 5 minutes the amount of water transferred will be ...
(20 gal/min)(5 min) = 100 gal
That is, Tower 1 will have 100 gallons less: 1650 -100 = 1550 gallons
and Tower 2 will have 100 gallons more: 570 +100 = 670 gallons.
__
(b) The quantity in tower 1 is ...
t1 = 1650 -20m
and the quantity in tower 2 is ...
t2 = 570 +20m
These will be equal when ...
t1 = t2
1650 -20m = 570 +20m . . . . . equation for finding m
1080 = 40m . . . . . . . add 20m-570
27 = m . . . . . . . divide by 40
