Her savings is the 25% amount... well, if we take 65 to be the 100%, how much is 25% of that?

\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
65&100\\
x&25
\end{array}\implies \cfrac{65}{x}=\cfrac{100}{25}

solve for "x", that's her savings

the cost of the jeans is 65 - x

What is the equation in slope intercept form of the line that passes through the points (-6,5) and (2,1) enter any fractions lik
Korvikt [17]

The equation of the line in slope-intercept form is given by

y=mx+b

step 1

Find out the slope m

we have the points (-6,5) and (2,1)

m=\frac{1-5}{2+6}=-\frac{4}{8}=-\frac{1}{2}

step 2

Find out the equation of the line

we have

m=-1/2

point (2,1)

substitute and solve for b

\begin{gathered} 1=-\frac{1}{2}(2)+b \\  \\ 1=-1+b \\ b=2 \end{gathered}

therefore

The equation of the line is

y=-\frac{1}{2}x+2

Problem N 2

Write the equation of the line in the point-slope form that passes through the point (-2,3) and has a slope of 1/2

The equation of the line in point-slope form is given by

y-y_1=m(x-x_1)

we have

m=1/2

point (-2,3)

substitute

\begin{gathered} y-3=\frac{1}{2}(x-(-2)) \\  \\ therefore \\ The\text{ answer is} \\ y-3=\frac{1}{2}(x+2) \end{gathered}

In Exercise,find the balance in the account after 10 years.
Vesnalui [34]

Answer: $ 3462.03

Step-by-step explanation:

The exponential equation for growth (compounded continuously) is given by :-

A=Pe^{rt}

, where P= Present value

r= growth rate  ( in decimal)

t= time

As per given , we have

P=$1900,  r = 6% =0.06  and t= 10

Substitute all the values in the above equation , we get

A=1900e^{0.06(10)}

A=1900e^{0.6}

A=1900(1.8221188)=3462.02572\approx3462.03  [To the nearest cent]

Hence, the balance in the account after 10 years = $ 3462.03

Find m&lt;1 <br> Please please
enyata [817]

Answer:

it should equal 68 degrees.

Step-by-step explanation:

if you are looking for the value of m<1, you would first need to find the value of the missing angle on the left triangle. the angles in triangles are equal to 180 degrees, so the equation would be 180 = 50 + 80 + x, and x = 50.

Then move to the middle triangle. The angle you solved for has an angle "connected" to it, its vertical pair, which also equals 50. Then you solve for the last angle, the angle on the right. 180 = 50 + 62 + x, and x = 68.

m<1 is equal to its vertical angle, which is the angle you just solved for. its value should be 68 degrees.

if that wasn't what you were looking for, sorry. hope this helped :)
