Write an equation of the line passing through the point(2,10)
that is perpendicular to the line 2x+y=17
Answers
slope of that equation is -2 and perpendicular slope is 1/2
use point slope form and put the point(2,10) and slope in there to get y-10= 1/2(x-2)
rearrange to get y=1/5x+9.6

Answer:
Step-by-step explanation:
[tex]Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-6-9}{2-4}=\dfrac{-15}{-2}=\dfrac{15}{2}\\\\[/tex]
Equation:
[tex]y -y_{1}=m(x -x{1})\\\\y - 9 = \dfrac{15}{2}(x-4)\\Multiply \ the \ entire \ equation \ by 2\\\\2*(y -9)=2*\dfrac{15}{2}(x-4)[/tex]
2y - 2*9 = 15(x - 4)
2y - 18 = 15x - 60
2y - 18 + 60 = 15x
2y + 42 = 15x
15x - 2y = 42

the book fair had a sale where 6 books were 20.46 If you wanted to buy 7 books how much money would need
Answers
Answer:
20.46 divided by 6 = 3.41
3.41 times 7 = 23.87
Step-by-step explanation:
Answer:
$23.87
Step-by-step explanation:
We can start by figuring out how much one book costs. To do this we divide 20.46 by 6.
20.46/6=3.41
Each book costs 3.41
Since we bought 7 books we multiply 3.41 by 7
3.41*7=$23.87

Answers
Answer:
1/6
Step-by-step explanation:
Given the function
f(x)=x^3+x^2+x
Get the inverse. Let y = f(x)
y = x^3+x^2+x
Replace y with x
x = y³+y²+y
Differentiate with respect to x
1 =3y²dy/dx + 2ydy/dx + dy/dx
1 = (3y²+2y+1)dy/dx
dy/dx = 1/3y²+2y+1
g'(x) = 1/3(g(x))²+2g(x)+1
If x = 3
g'(3) = 1/3(g(3))²+2g(3)+1
g'(3) =1/3(1)²+2(1)+1
g'(3) = 1/3+2+1
g'(3) = 1/6
Hence g'(3) = 1/6

since we know on straight line 180° is formedthen➡90° +(x+x+x)= 180°
➡90° + 3x = 180°
➡3x= 180°-90°
➡3x= 90°
➡x = 90°/3= 30°
➡x= 30°then in triangle sum of all angles = 180°➡90°+x+y = 180°
➡90°+ 30° +y = 180°
➡120+y = 180°
➡y= 180°-120°
y = 60now to find y-x = 60°-30°=30➡30 is correct answer

A student estimated a mass of 250grams, according to the scale the mass is actually 240grams. What is the percent error? (round to tenths place
Answers
Answer:
4.2%
Step-by-step explanation:
percent error = (estimated value - actual value)/(actual value) × 100%
Here, the estimated value is 250 g, and the actual value is 250 g.
percent error = (estimated value - actual value)/(actual value) × 100%
percent error = (250 g - 240 g)/(240 g) × 100%
percent error = 10/240 × 100%
percent error = 0.041666... × 100%
percent error = 4.2%
Step-by-step explanation:
the real thing is 240 grams.
the estimation of 250 grams was 10 grams off.
how many % is that ?
for that we need to divide these 10 by 1%.
and 1% is 240/100 = 2.4 grams.
10 / 2.4 = 4.166666666... ≈ 4.2%
the percent error is 4.2%
