I Nisa buy dollars worth of stock and gained $25 per year Kevin bad for hundred dollars worth of stock in the last $35 per year
alisha [4.7K]

Answer: x= 5 years and y = $225

Step-by-step explanation:

Since we have given that

Amount Nisa gained per year = $25

Amount Kevin lost per year = $35

According to question,

y=100+25x\\\\and\\\\y=400-35x

so, it becomes,

100+25x=400-35x\\\\25x+35x=400-100\\\\60x=300\\\\x=\frac{300}{60}\\\\x=5

so, For x= 5 years,

Their income of Nisa and loss of Kevin will be

y=100+25x\\\\y=100+25\times 5\\\\y=100+125\\\\y=\$225

What is the length of a line segment on the coordinate plane with end point (3,5) and (6,8) to the nearest tenth
yan [13]

Answer:

Step-by-step explanation:

Use the distance formula for coordinate geoemetry and the fact that x1 = 3, y1 = 5, x2 = 6 and y2 = 8 to fill in the formula:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

fills in accordingly:

d=\sqrt{(6-3)^2+(8-5)^2}

which simplifies a bit to

d=\sqrt{(3)^2+(3)^2}

which is

d=\sqrt{18}

The square root of 18 simplifies down to 3\sqrt{2}, which is 4.2426 in decimal form

Which is the additive inverse of the complex number -8+3i?
lawyer [7]
The additive inverse of a complex z is a complex number -z, so that

\mathsf{z+(-z)=-z+z=0+0i=0}


Finding -z:

\mathsf{z=-8+3i}\\\\\\ \mathsf{z+(-z)=0+0i}\\\\\ \mathsf{-8+3i+(-z)=0+0i}\\\\ \mathsf{-z=0+0i+8-3i}\\\\ \mathsf{-z=(0+8)+(0i-3i)}\\\\ \boxed{\begin{array}{c}\mathsf{-z=8-3i} \end{array}}\qquad\checkmark
