Answer:

Step-by-step explanation:

Proof:

If:

x intercept is at a number nonzero "a"

so the point where it intersects the x-axis is at (a,0)

y-intercept is at the same nonzeronumber "a"

so the point where it intersects the y-axis is at (0,a)

Then:

slope between point (a,0) and (0,a) is m= (y2-y1)/(x2-x1) = 0-a/a-0=-a/a= -1

x intercept is 2 (for example)

so the point where it intersects the x-axis is at (2,0)

y-intercept is 2

so the point where it intersects the y-axis is at (0,2)

slope between point (2,0) and (0,2) is m= (y2-y1)/(x2-x1) = 0-2/2-0=-2/2=-1

Answer:

Raphael sells paintings for $200 each at a market, but has to pay $100 to reserve a table. :)

Step-by-step explanation:

The scenario that describes a proportional relationship is D; Raphael sells paintings for $200 each at a market but has to pay $100 to reserve a table.

Let there are two variables p and q

Then, p and q are said to be directly proportional to each other if

p = kq

where k is some constant number called constant of proportionality.

This directly proportional relationship between p and q is written as

[tex]p \propto q[/tex]where that middle sign is the sign of proportionality.

This inversely proportional relationship is denoted by;

[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]

Thus, the scenario that describes a proportional relationship is D; Raphael sells paintings for $200 each at a market but has to pay $100 to reserve a table.

Answer:

(5,-1)

Step-by-step explanation:

TAKE ONE SIDE

(X-5)2=0

2X-10= 0

2X=10

X=10/2

X=5

THEN TAKE OTHE SIDE

-2(y+1) =0

-2y-2=0

-2y=2

y=2/-2

y=-1

So the answer is (5,-1)

And it should be in right down

(-5,1) , the graph opens down

'An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.'

.Given equation: 2(x-5) = -2(y+1)

Evaluating left-hand side,

⇒ (x-5)2 = 0

⇒2x-10 = 0

⇒2x = 10

⇒x =10/2

⇒x = 5

Evaluating RHS,

⇒-2(y+1) = 0

⇒-2y-2 = 0

⇒-2y = 2

⇒y = 2/-2

⇒y = -1

Hence, we can conclude the vertex is at (-5,1) and the graph opens down.

Answer:

(4, 1)

Step-by-step explanation:

since y=1/2x-1 in the first equation, you can substitute it into the second one:

1/2x - 1 = -x + 5

then add x to both sides:

3/2x - 1 = 5

then add 1 to both sides:

3/2x = 6

then divide both sides by the fraction to get:

x=4

then you substitute 4 into y=1/2x - 1

y = 1/2(4)-1

y = 1

so your answer is x=4 and y=1

Answer:

C. Y=4/25x

Step-by-step explanation:

If y varies directly as x, tis is expressed as;

y ∝ x

y = kx

k is the constant of proportionality

Goven

y = 16/5 and x = 20

16/5 = 20k

16 = 100k

k = 16/100

k = 4/25

Substitute k = 4/25 into the original equation

y = kx

y = 4/25 x

Hence the required expression is y = 4/25 x

Answer:

This function doesn't make sense, unless you make it f(t)=225(1.23)^x. I will assume that you forgot to add the x squared. The rate of decay is 23%. Since the base is between 1 and 0, it is an exponential decay and you'll need to subtract the r-value with 1. (If it were an exponential growth, you would have to add 1.) The initial value or the a-value is 225.

Answer:

t = ln1.5/0.25

t = 1.622

Step-by-step explanation:

Gives the equation, 6*e^{0.25t}=9

We are to find t

6*e^{0.25t}=9

e^{0.25t}=9/6

e^{0.25t}= 1.5

Apply ln to both Sides

ln( e^{0.25t) = ln1.5

0.25t = ln1.5

t = ln1.5/0.25

t = 1.622

Step-by-step explanation:

Answer:

3 ft = 91.44 cm

Step-by-step explanation:

We want to convert 3 ft to cm.

So we need a conversion factor.
