Answer:

Table N 1

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In this problem the table N 1 represent a proportional relationship

Find the value of k

R/S=k

For R=5, S=1

substitute

tex]k=5/1=5[/tex]

For R=10, S=2

substitute

k=10/2=5

For R=15, S=3

substitute

k=15/3=5

For R=20, S=4

substitute

k=20/4=5

For R=25, S=5

substitute

k=25/5=5

the equation of the proportional relationship is equal to

R=5S

Use Inverse operations to solve the expression. Enter your answer in simplest form. y 1 =8 16​
vredina [299]
So we are trying to get the “y” alone, so to undo the division by -8, we will multiply both sides by -8, then simplify.

(-8) y/(-8) = (-8) 1/16

y = -8/16

and simplified:

y = -1/2

Find the value of x.
Ainat [17]

Answer:

\textsf{x=22.5}

Step-by-step explanation:

\textsf{According to intersecting tangent - secant theorem,}

\textsf{x=1/2[(4x+5)-50]}

\textsf{2(x)=4x+5-50}

\textsf{2x=4x-45}

\textsf{2x-4x=-45}

\textsf{-2x=-45}

\textsf{x= -45/-2}

\textsf{x=22.5}

Find the slope of every line that is parallel to the graph of the equation x+7y=6
raketka [301]
x+7y=6

7y=-x+6

(7y)/7=(-x+6)/7

y=(-1/7)x+6/7


Since, y=mx+b and m is the slope

m=-1/7

Solve by substitution <br> X^2= 2y + 10<br> 3x-y = 9
Viefleur [7K]

Answer:

x=-4\\ x=-2\\ y=-21\\ y=-15

Step-by-step explanation:

x^{2} =2y+10

y=-9+3x

x^{2} =2(-9+3x)+10

x^{2} =-18+6x+10

x^{2} =6x-8

x^{2} -6x+8

x=-4, -2

y=-9+3(-4)

y=-9-12

y=-21

y=-9+3(-2)

y=-9-6

y=-15
