Answer:

y = 5.543

Step-by-step explanation:

Your y = 7(1 - 0.021)^11 is evaluated as follows:

y = 7(0.979)^11

y = 7(0.7918

y = 5.543

Find the slope and y-intercepts <br> f(x)= -1/2x - 2
gavmur [86]

Answer:

slope: -1/2

y-intercept: -2

Step-by-step explanation:

f(x) = mx+b

m is slope

b is the y-intercept

so

if f(x) = -1/2x - 2

then

the slope or m is -1/2

and the y-intercept or b is -2

Can someone please help me, it's science and math put together I just don't understand how to do this problem maybe it's the way
sergij07 [2.7K]
What ?  What ? 
Did you write the first two answers in pencil ?
They're correct !  Just do the other two exactly the same way.

-- Do the division problem printed in the "Distance ..." column.

-- Multiply the answer by  0.1 .

-- Write the new answer in the last column.

I already answered this but I just want to make sure if I did it right
galben [10]
\bf \left( \cfrac{2}{3} \right)^3\cdot \left( \cfrac{3}{5} \right)^3\implies \cfrac{2^3}{\underline{3^3}}\cdot \cfrac{\underline{3^3}}{5^3}\implies \cfrac{2^3}{5^3}\implies \cfrac{8}{125}

A table contains the ordered pairs (3, 42.25) and (5, 50.75). If the relationship in the table is linear, explain how to find th
aniked [119]

Answer:

The initial value is 29.5

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept ( also called initial value)

we have the points

(3,42.25) and (5,50.75)

Find the slope m

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{50.75-42.25}{5-3}

m=\frac{8.5}{2}

m=4.25

substitute in the equation

y=4.25x+b

<em>Find the value of b</em>

with the point (3,42.25)  ( or the other given point)

substitute the value of x and the value of y in the equation and solve for b

42.25=4.25(3)+b

42.25=12.75+b

b=42.25-12.75

b=29.5

substitute

The linear equation is

y=4.25x+29.5

The initial value is the y-intercept (value of y when the value of x is equal to zero)

For x=0

y=4.25(0)+29.5

y=29.5

Therefore

The initial value is 29.5
