Answer:

B=11

Step-by-step explanation:

b=10 a=8

b=? a=9

Either you can cross multiple 10x9=90/8 (11.25, round down to 11), or you can look that 9 is 8+1, so of we do the same process to b then we would find our awnser. 10+1=11.

When a is 9 then, the value of b will be;

⇒ b = 45/4

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

'b' is directly proportional to a.

And, b is 10 when a is 8.

Now,

Since, 'b' is directly proportional to a.

Hence, We get;

⇒ b = ka

Where, k is constant of proportionality.

Here, b is 10 when a is 8.

So, Put b = 10 and a = 8;

⇒ b = ak

⇒ 10 = k × 8

⇒ k = 10 / 8

⇒ k = 5/4

So, When a is 9 and k is 5/4, then;

⇒ b = ak

⇒ b = 9 × 5/4

⇒ b = 45/4

Thus, The value of b = 45/4

Answer:

y = 20 + 35x or y = 35x + 20

Step-by-step explanation:

Looking at the problem, a cell phone company charges $20 for a new account, and $35/month for phone service. With that information we can quickly form this equation:

y = 20 + 35x

The y is the total cost, 20 is the initial charge, and 35x is the per-month charge.

What is below is the graph for this equation.

Answer:

x=10.247

y=52.02

z=37.98

Step-by-step explanation:

For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.

For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle

For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle

Answer:

All is in the picture

Answer:

I believe you can just distribute (multiply) the coefficient (the number/value that is outside of the parentheses) by the rest of the values.

Step-by-step explanation:

So c. would be (20y * 1/5) (-4x * 1/5) (-13 * 1/5) then you just solve.

Answer:

A) 70

Answer:

x=8 y=1

Step-by-step explanation:

you have first and second equation, YOU MUST FIND THE THIRD EQUATION

SOLUTION

FIND equation 3 from 2

x+2y=10

x=10-2y...........3

Substitute equation 3 from first (not from the equation where you got equation 3)

2 (10-2y)-7y=9

20-4y-7y=9

-11y=9-20

-11y= -11

-11y/-11= -11/-11

y=1

Find the value of x from the third equation

x=10-2 (1)

x=8

Answer:

x=-4/3, y=3/-5

Step-by-step explanation:

X+2X=-4

Then, adding up we get: 3x=-4

Then, x=-4/3

Substituting those we get: 3*(-4/3)-5y=-1

-4-5y=-1

-5y=-1+4=3

y=3/-5

Thus, x=-4/3, y=3/-5
