Solve for the value of y.​

Answers

Answer:

y=6

Step-by-step explanation:

add both expressions together. 14y+6. Then set this equal to 90, because this is a 90 degree angle. Solve for y. 84=14y. y=6

Step-by-step explanation:

90= 6y+5+8y+1

14y=84

y=6

the equation of the line that has a slope of

-23 that passes through the point (5, 1). Which form did you choose to write the equation in and why?

Answers

Y = -23x + b
1 = -23(5) + b
1 = -115 + b, b = 116
Y = -23x + 116
I choose the slope intercept form since it was easy to calculate. The slope was given, you just need to plot in the points to find the y- intercept.

Answer:

I used the y=Mx+b equation because it has a good job showing each of the elements in the equation.

Step-by-step explanation:

The slope is -2/3 so if you add it to (5,1) it would be (3,4) as you just add three and subtract to to the point. I’m going to use for this equation as it is more simple and it gives a good job showing what each element is in the equation. M is the slope, so now we have y= -2/3x +b. To find b, substitute x and y for a point on this line which I will use the point (3,4) for. Now, multiply -2/3 by 3 and you will get -2 after. Now you have 4=-2+b which the answer would be 6.

This is just an example of finding the equation, which form I used, and why.

Answers

Answer:y  = − 1 5 x + 4

Step-by-step explanation:

Do elimination
x + 5y = 20
x + 3y = 14
Subtract both equations
2y = 6
y = 3
Plug in 3 for y and solve for x
x + 5(3) = 20
x + 15 = 20
x = 5
In conclusion, x = 5, y = 3

Answers

Answer:

60°

Step-by-step explanation:

Because of the rule that all triangle's angles must measure to 180°.

So I did...

60+60=120

180-120= 60

Answer

60 degrees

Step-by-step explanation:

A triangle is 180 degrees. So if you add both 60 degrees it would equal 120, substracted by 180 and you'll get 180. Or if you want to go the faster way, remember that a triangle will equal 180.

Zayd can row 3/8 of a mile in 1/4 of an hour. What is the unit rate the describes the miles per hour?

Answers

Answer:

1.5mph

Step-by-step explanation:

Given parameters:

Distance sailed  = [tex]\frac{3}{8}[/tex]miles

Time taken  = [tex]\frac{1}{4}[/tex]hr

Unknown:

 Unit rate of sail in miles hour = ?

Solution:

This is also the speed of the sail. It is the distance divided by time taken.

 Speed  = [tex]\frac{distance}{time}[/tex]  

 Speed  = [tex]\frac{\frac{3}{8} }{\frac{1}{4} }[/tex]  

 Speed  = [tex]\frac{3}{8}[/tex]  x 4 = 1.5mph

because -5 + 3 = -2 and -5 X 3 = -15.

-5 is bigger in -5 + 3 so your answer would be negative.

and for the multiplication on use the sleeping dog - - + you have a negative and a positive so the answer would be negative.

For |x| < 1, we have

[tex]1+x+x^2+\cdots=\displaystyle\sum_{n\ge0}x^n=\frac1{1-x}[/tex]

We have |sin(x)| ≤ 1, with equality when x = ± π/2. For either of these, the right side of the equation does not converge, since it's either an infinite sum of 1s or an infinite alternating sum of 1 and -1.

So for |sin(x)| < 1, we have

[tex]\sin(x)+\sin^2(x)+\sin^3(x)+\cdots=\dfrac1{1-\sin(x)}-1=\dfrac{\sin(x)}{1-\sin(x)}[/tex]

so the equation is equivalent to

[tex]\dfrac{\sin(x^2-1)}{1-\sin(x^2-1)}=\dfrac{\sin(x)}{1-\sin(x)}[/tex]

One obvious set of solutions occurs when x = x² - 1 :

x² - x - 1 = 0   →   x = (1 ± √(5))/2

i.e. the golden ratio φ ≈ 1.618 and 1 - φ ≈ 0.618.
