7x+8y=18 Find the equation of the line which passes through the point (1,−13) and is parallel to the given line. Express your answer in slope-intercept form. Simplify your answer.
Answer:
y = -7/8x - 97/8
or 8y + 7x = -97
Step-by-step explanation:
7x + 8y = 18
=> 8y = -7x + 18
y = -7/8 + 18/8
If two lines are parallel, their slopes are equal. So slope is -7/8
given m = -7/8, y = -13, x = 1
y = mx + b
-13 = -7/8(1) + b
-13 = -7/8 + b
b = -13 + 7/8 = -104/8 + 7/8 = -97/8
so y = -7/8x - 97/8
=> 8y = -7x - 97
8y + 7x = -97

linda started to run on a treadmill after setting its timer for 83 minutes the display says she has finished 74 percent of her run how many minutes have gone by
Step-by-step explanation:
100% = 83 minutes
1% = 100%/100 = 83/100 = 0.83 minutes
74% = 1%×74 = 0.83 × 74 = 61.42 minutes
Lol can someone help me understand this i’m mad confused and I’m tryna get my grade up
Answer:
y-(-8)=4(x-2)
Step-by-step explanation:
This is point-slope form. Point-slope form is y-y₁=m(x-x₁), this is y minus the change in y equals slope (slope is m) times x minus the change in x. An ordered pair is (x, y). You just plug in the missing values. This will get you y-(-8)=4(x-2). I hope this helps! Also, make sure not to put the parenthesis around -8 in the actual box! They are just there to make for less confusion.
The model y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold. Using the linear regression model, approximate the number of ice cream cones sold when it is 85°F. Round your answer to the nearest whole number.
When it is 85°F, they will sell approximately _ ice cream cones.
Graph of linear equation will be always straight line.
Number of ice cream cones sold be 76.
The relationship between the temperature (°F) and the number of ice cream cones sold is given by model,
[tex]y=1.8x-76.9[/tex]
Where x represent temperature and y represent number of ice cream cone sold.
When temperature is 85°F , it means that , x = 85°F
So, [tex]y=1.8*85-76.9\\\\y= 76.1[/tex]
Thus, number of ice cream cone sold is to be 76.

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set Up Equation
69° + 62° + (x + 54)° = 180°
Step 2: Solve for x
Combine like terms: x + 185 = 180Subtract 185 on both sides: x = -5Answer:
Step-by-step explanation:
x + 54 + 69 + 62 = 180 Every triangle has 180 degrees
x + 185 = 180 Subtract 185 from both sides
x = - 5

Which statement about triangles is true?
A. A triangle can have 2 acute angles.
B. A right triangle can have 2 right angles.
C. An obtuse triangle can have 2 obtuse angles.
D. A triangle can have 1 right angle and 1 obtuse angle.
Answer:
[tex] \fbox{A triangle can have 2 acute angles.}[/tex]
Step-by-step explanation:
Acute angle : The angle whose measure is less than 90° is called actute angle.
Obtuse angle : The angle whose measure is more than 90° is called obtuse angle.
Right angle : The angle whose measure is exact 90° is called right angle.
Property of triangle: The measure of all three angles of a triangle is 180°.
let's solve the actual question now,
Option A - let a triangle have two acute angle x and y respectively and z third angle of the respective triangle,
x + y + z = 180°
(<90°) + (<90°) + z = 180°
z = 180 - (<180)
z <180
the measure of 3rd angle z will be less than 180,
hence a triangle can have 2 acute angles.
Option B - let a right angle triangle have two right angles x and y respectively and z third angle of the respective triangle,
x+y+z = 180
90+90+z = 180
z = 180-180 = 0°
which means the third angle z does not exist and it is not a triangle. Hence a right angle triangle can only have one right angle.
Option C - let a triangle have two obtuse angle x and y respectively and z third angle of the respective triangle,
x + y + z = 180°
(>90°) + (>90°) + z = 180°
z = 180 - (>180)
when one number is subtracted from another number which is greater than that then the result obtain is negative. So the value of third angle z will be negative which is a flaw. Hence third option is also incorrect.
Option D - let a triangle have one right angle and one obtuse angle x and y respectively and z third angle of the respective triangle,
x + y + z = 180°
(90°) + (>90°) + z = 180°
z = 180 - (>180)
Same as option C, the third angle is negative which is a flaw and this option is incorrect too.
Conclusion- A triangle can have 2 acute angles and one right angle. So option A is the correct match.

Supriya invested $14,320 in a highly rated ETF. At the end of four years, she had $18,434. What was her annual effective yield on this investment? Enter your answer as a percent rounded to four decimal places.
Answer:
6.517%
Step-by-step explanation:
This is a multi-year investment and we are not working with a $1 initial investment. There is no mention of compounding so we will use formula A=P0⋅(1+r)N with A=$18,434 and P0=$14,320. We do not know the value of r. However, N=4 years. Substituting the values we have $18,434=$14,320⋅(1+r)4. Divide both sides of the equation by $14,320. Next, take the fourth root of both sides of the equation and subtract 1 to find the decimal form of r.
$18,4341.287291.065170.06517=$14,320⋅(1+r)4=(1+r)4=1+r=r
Finally, convert r to a percent.
r=0.06517×100%=6.517%

The real numbers x and y satisfy the equations:
xy - x = 180 and y + xy = 208.
Let the two solutions be (x1, y1 and (x2, y2).
What is the value of x1 + 10y1 + x2 + 10y2
Answer:
The value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is 317.
Step-by-step explanation:
Let the system of nonlinear equations be:
[tex]x\cdot (y-1) = 180[/tex] (1)
[tex]y\cdot (1+x) = 208[/tex] (2)
From (1), we clear [tex]x[/tex]:
[tex]x = \frac{180}{y-1}[/tex]
Let apply this resulting expression in (2):
[tex]y\cdot \left(1+\frac{180}{y-1} \right)= 208[/tex]
[tex]y\cdot \left(\frac{y-1+180}{y-1} \right) = 208[/tex]
[tex]y\cdot \left(\frac{y+179}{y-1} \right)=208[/tex]
[tex]y\cdot (y+179) = 208\cdot (y-1)[/tex]
[tex]y^{2}+179\cdot y = 208\cdot y-208[/tex]
[tex]y^{2}-29\cdot y+208 = 0[/tex]
By the Quadratic Formula we obtain the solution of the second order polynomial:
[tex]y_{1} = 16[/tex] and [tex]y_{2} = 13[/tex]
And the respective values of [tex]x[/tex] are, respectively:
[tex]y_{1} = 16[/tex]
[tex]x_{1} = \frac{180}{y_{1}-1}[/tex]
[tex]x_{1} = \frac{180}{15}[/tex]
[tex]x_{1} = 12[/tex]
[tex]y_{2} = 13[/tex]
[tex]x_{2} = \frac{180}{y_{2}-1}[/tex]
[tex]x_{2} = \frac{180}{12}[/tex]
[tex]x_{2} = 15[/tex]
If we know that [tex]x_{1} = 12[/tex], [tex]y_{1} = 16[/tex], [tex]x_{2} = 15[/tex] and [tex]y_{2} = 13[/tex], then the value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is:
[tex]f = 12+10\cdot (16)+15+10\cdot (13)[/tex]
[tex]f = 317[/tex]
The value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is 317.
