Answer:
The parallel equation is y=[tex]\frac{5}{2}[/tex]x-5.
The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.
Step-by-step explanation:
First solve for y.
-5x+2y=8
2y=5x+8
y=[tex]\frac{5}{2}[/tex]x+4
A line is parallel if it has the same slope, but different y-intercepts.
The y-intercept of the given point is -5, so the new slope will be y=[tex]\frac{5}{2}[/tex]x-5
To find a perpendicular line, you find the negative reciprocal of the given slope.
So you find [tex]\frac{-1}{\frac{5}{2} }[/tex], which is equal to [tex]\frac{-2}{5}[/tex].
The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.
Answer:
Step-by-step explanation:
A straight line will be parallel to another straight line only if their slopes are equal .A straight line will be perpendicular to another straight line only when the product of their slopes is -1 Part ALet 's bring the function -5x+2y=8 to the standard form 2y=8+5x y=2,5x+4 A parallel line passes through a point (-5; -3); and this meansy=2,5x+b 2,5*(-5)+b=-3 b=9,5 y=2,5x+9,5 -straight parelenai straight y=2.5x+4 Part B Let 's bring the function -5x+2y=8 to the standard form y=2,5x+4 y=kx+b And we know k*2,5=-1=> k=-0,4 y=-0,4x+b -0,4*(-5)+b=-3b=-1y=-0,4x-1 - Straight perpendicular to the straight line y=2.5x+4I’ve spent too long on this.

Answer:
14 10 cent coins
Step-by-step explanation:
Assumption method:
Assume all are 10 cent
10x48=$4.80
8.20-4.80=3.40
10x47=$4.70
1x20=$0.20
$4.70+$0.20=$4.90
Gap= $3.40
Difference=$4.90-$4.80=$0.10
Gap÷Difference= $3.40÷0.10=34 20 cent coins
48-34=14 10 cent coins

Step-by-step explanation:
If f(x) is an exponential function where f(-2) = 1 and f(7) = 63, then find the
value of f(1), to the nearest hundredth.
An exponential function is represented as: [tex]\mathbf{f(x) = ab^x}[/tex]
The value of f(1) is 3.95
f(-2) = 1 means that:
[tex]\mathbf{ab^{-2} = 1}[/tex]
f(7) = 63 means that:
[tex]\mathbf{ab^{7} = 63}[/tex]
Divide both equations
[tex]\mathbf{\frac{ab^7}{ab^{-2}} = \frac{63}{1}}[/tex]
Apply law of indices
[tex]\mathbf{b^9 = 63}[/tex]
Take 9th root of both sides
[tex]\mathbf{b =1.58}[/tex]
Make a, the subject in [tex]\mathbf{ab^{-2} = 1}[/tex]
[tex]\mathbf{a = \frac{1}{b^{-2}}}[/tex]
[tex]\mathbf{a = b^2}[/tex]
Substitute [tex]\mathbf{b =1.58}[/tex]
[tex]\mathbf{a = 1.58^2}[/tex]
[tex]\mathbf{a = 2.50}[/tex]
So, we have:
[tex]\mathbf{f(x) = ab^x}[/tex]
[tex]\mathbf{f(x) = 2.50 \times 1.58^x}[/tex]
Substitute 1 for x
[tex]\mathbf{f(1) = 2.50 \times 1.58^1}[/tex]
[tex]\mathbf{f(1) = 3.95}[/tex]
Hence, the value of f(1) is 3.95

Determine whether the pair of lines is parallel, perpendicular, or neither.
x−2y=−1
y=5x−3
Answer:
neither
Step-by-step explanation:
put the first equation in slope intercept form
x-2y=-1
-2y= -x -1
y = 1/2x +1/2
the slope is not the same, and it is not the opposite, so it is neither

Find the measure of each marked angle.
Answer:
X= 15, m∠78°
Step-by-step explanation:
Since the angles are vertically opposite
Therefore their measurements are equal
Therefore (2x + 48 ) = (5x + 3 )
So,
[tex](2x + 48) = (5x + 3)\\(2x-5x)= (3-48)\\-3x = -45\\x = -45/-3\\x = 15[/tex]
[tex](2x + 48)\\=( 2* 15 + 48)\\= 30 + 48\\=78\\\\(5x + 3)\\=(5*15 + 3)\\=75+3\\=78[/tex]
They both equal 78°

Hey there!
5x - 50 + 2x + 80 - x = 180
COMBINE the LIKE TERMS
= 6x + 30 = 180
SUBTRACT 30 to BOTH SIDES
6x + 30 - 30 = 180 - 30
CANCEL out: -30 - 30 because that gives you 0
KEEP: 180 - 30 because it helps solve for the x-value
6x = 180 - 30
180 - 30 = 150
NEW EQUATION: 6x = 150
DIVIDE 6 to BOTH SIDES
6x/6 P 150/6
CANCEL out: 150/6 because that gives you the result of the x-value
x = 150/6
SIMPLIFY IT!
x = 25
Therefore, your answer is: x = 25
