The equation of a line is y = 2/3x + 5. What is an equation of the line that is perpendicular to the given line and that passes through the point (4, 2)?
Step-by-step explanation:
line that is perpendicular to the given line :
y = 2/3x + 5
m1 × m2 = -1
m1 = the coefficient of x
m1 = 2/3
remember : m1 × m2 = -1
2/3 x m2 = -1
2m2 ÷ 3 = -1
(let m2 = x)
2x ÷ 3 = -1
(cross multiply)
2x = 3 × -1
2x = -3
(divide both sides by the coefficient of x)
x = -3/2
Remember : m2 =x
m2 = -3/2
The line that passes through the point (4,2) ;
( note : x¹ = 4 , y¹ = 2)
m = (y - y1) ÷ (x - x1 )
-3/2 = (y - 2) ÷ (x - 4)
(cross multiply)
-3(x - 4) = 2 (y - 2)
-3x +12 = 2y - 4
(make y the subject of formula )
-3x + 12+ 4 = 2y
-3x + 16 = 2y
(
(divide through by the coefficient of y)
-3x/ 2 + 16/2 = y
-3/2x + 8 = y

Find the small positive integer solution that solves the equation. if there is no solution, type NONE.
(8x)(mod 13)≡4
x=?
9514 1404 393
Answer:
x = 7
Step-by-step explanation:
The equation can be rewritten to ...
8x = 13n +4 . . . . for some integers x and n
x = (13n +4)/8
For x to be an integer, 13n must be an odd multiple of 4. Since 13 is an odd number, n=4 will do.
x = (13·4 +4)/8 = 56/8
x = 7
__
The graph shows a "trial and error" method of solution. Only values of x less than 13 need to be examined.

The exchange rate for 1 dollar is 1.3021 euros
Answer:
889.021796 (or simplifyed, 889.02)
Step-by-step explanation:
1 USD = 1.3021 EU
so what we do here is multiply 1.3021 and 682.76
1.3021 x 682.76 = 889.021796

What is the equation of a hyperbola with a = 5 and c = 15? Assume that the transverse axis is horizontal.
Answer:
[tex]\frac{x^2}{25} -\frac{y^2}{200} =1[/tex]
Step-by-step explanation:
Recall that the equation of hyperbola centered at the origin with transverse horizontal axis has the general form:
[tex]\frac{x^2}{a^2} -\frac{y^2}{b^2} =1\\and\,\,\,\, with\\c=\sqrt{a^2+b^2}[/tex]
since we know that a = 5 ,and c = 15,we can solve for b:
[tex]15=\sqrt{5^2+b^2} \\15^2=25+b^2\\b^2=200\\[/tex]
then the equation of the hyperbola becomes:
[tex]\frac{x^2}{5^2} -\frac{y^2}{200} =1\\\frac{x^2}{25} -\frac{y^2}{200} =1[/tex]

What is the solution for 2X- 5=7
Answer:x = 6
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
Add 5 to both sides of the equation:
2x -5 = 7
2x -5 +5 =7 +5
Simplify:
2x=12
Divide both sides of the equation by the same term:
2x = 12
2x/2 = 12/2
Simplify again:
x=6
Answer:
x = 6

f(x)=−10x2−x and g(x)=−2x2−x, find (f−g)(x) and (f−g)(−2)
Answer:
(f - g)(x) = -8x²
(f - g)(2) = -32
General Formulas and Concepts:
Algebra I
Combining like termsStep-by-step explanation:
Step 1: Define
f(x) = -10x² - x
g(x0 = -2x² - x
(f - g)(x) is f(x) - g(x)
(f - g)(2) is f(2) - g(2)
Step 2: Find (f - g)(x)
Substitute: (f - g)(x) = -10x² - x - (-2x² - x)Distribute -1: (f - g)(x) = -10x² - x + 2x² + xCombine like terms: (f - g)(x) = -8x²Step 3: Evaluate
Substitute: (f - g)(2) = -8(-2)²Evaluate: (f - g)(2) = -8(4)Multiply: (f - g)(2) = -32And we have our answers!

Find the coordinates of point P that lies along the directed line segment AB in a 2:3 ratio given A (-2, 1), B (3, 4).
Answer:
[tex]P(x,y) = (0,\frac{11}{5})[/tex]
Step-by-step explanation:
Given
[tex]A = (-2,1)[/tex]
[tex]B = (3,4)[/tex]
[tex]m:n = 2:3[/tex]
Required
Determine the coordinates of P
The coordinate of a point when divided into ratio is:
[tex]P(x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]
Where
[tex](x_1,y_1) = (-2,1)[/tex]
[tex](x_2,y_2) = (3,4)[/tex]
[tex]m:n = 2:3[/tex]
This gives:
[tex]P(x,y) = (\frac{2 * 3 + 3 * -2}{2 + 3},\frac{2 * 4 + 3 * 1}{2 + 3})[/tex]
[tex]P(x,y) = (\frac{6 - 6}{5},\frac{8 + 3}{5})[/tex]
[tex]P(x,y) = (\frac{0}{5},\frac{11}{5})[/tex]
[tex]P(x,y) = (0,\frac{11}{5})[/tex]

Given △XPS≅△DNF, find the values of x and y.
Answer:
x = 3
y = 15
Step-by-step explanation:
If △XPS ≅△DNF, their corresponding sides would be congruent. This implies that:
XP ≅ DN
PS ≅ NF
XS ≅ DF
Given that:
XP = 4y - 3
DN = 57
NF = 51
XS = 17x + 3
DF = 54
Therefore:
XP = DN
4y - 3 = 57 (Substitution)
Add 3 to both sides
4y = 57 + 3
4y = 60
Divide both sides by 4
y = 60/4
y = 15
Also,
XS = DF
17x + 3 = 54 (substitution)
Subtract 3 from each side
17x = 54 - 3
17x = 51
Divide both sides by 17
x = 51/17
x = 3
