<h3>Given:-</h3>

⟹-5u-1=4

⟹-5u=4+1

⟹-5u=5

⟹u=\frac{5}{-5}

<h3>⟹u=-1</h3>

<h3>Substitute The Value</h3>

⟹7u+1

⟹7×(-1) +1

10) Solve using any method<br> 10x+2y=42<br> 5x+y=20
KIM [24]

Answer:

no solutions

Step-by-step explanation:

10x+2y=42

5x+y=20

Multiply the second equation by -2 to use elimination

-2(5x+y)=20*-2

-10x -2y = -40

Add this to the first equation

10x+2y=42

-10x -2y = -40

--------------------------

0 = 2

This is never true.  This means there are no solutions

The box plots show attendance at a school dance competition and school badminton games.
Helen [10]

Answer:

The IQR is a better measure of spread for dance competitions than for badminton games.

Step-by-step explanation:

I understand from "Dance Competition box plot has interquartile ranges approximately between 60 and 130" that quartile 1 is at 60 and quartile 3 is at 130, then, the interquartile range (IQR) is 130 - 60 = 70.

Similarly, from Badminton box plot, quartile 1 is at 90 and quartile 3 is at 150, then, the interquartile range is 150 - 90 = 60.

IQR is a measure of statistical dispersion, that is, as IQR increase, spread increase.

Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of si
Alex777 [14]

Answer:

\frac{15}{8}

Step-by-step explanation:

By applying Pythagoras theorem in the triangle given in the picture,

(Hypotenuse)² = (leg 1)² + (leg 2)²

PO² = (15)² + 8²

PO² = 225 + 64

PO = √289

PO = 17

By applying sine rule in the given triangle,

sin(x°) = \frac{Opposite Side}{Hypotenuse}

=\frac{15}{17}

cos(y°) = \frac{Adjacent Side}{Hypotenuse}

Relation between the ratio of sin(x) and cos(x) will be,

\frac{sin(x)}{cos(x)}= \frac{15/17}{18/17}

= \frac{15}{8}
