The circle on is a not function because the line will touch but ends

Answer:

it si this

Step-by-step explanation:

Simplifying

4y + -10 = 5 + -1y

Reorder the terms:

-10 + 4y = 5 + -1y

Solving

-10 + 4y = 5 + -1y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add 'y' to each side of the equation.

-10 + 4y + y = 5 + -1y + y

Combine like terms: 4y + y = 5y

-10 + 5y = 5 + -1y + y

Combine like terms: -1y + y = 0

-10 + 5y = 5 + 0

-10 + 5y = 5

Add '10' to each side of the equation.

-10 + 10 + 5y = 5 + 10

Combine like terms: -10 + 10 = 0

0 + 5y = 5 + 10

5y = 5 + 10

Combine like terms: 5 + 10 = 15

5y = 15

Divide each side by '5'.

y = 3

Simplifying

y = 3

Two mechanics Worked on a car The first mechanic charge $55 per hour The second mechanic charge $80 per hour the mechanics work

Tems11 [23]

a = hours worked by the first mechanic

b = hours worked by the second mechanic.

since the first mechanic charges $55 per hour, then for "a" hours that'd be a total of 55*a or 55a, likewise, for the second mechanic that'd be a total charge of 80*b or 80b.

we know all hours combined are 15, so then a + b = 15.

we also know that all charges combined are $950, so 55a + 80b = 950.

$\bf \begin{cases} a+b=15\\ \boxed{b}=15-a\\ \cline{1-1} 55a+80b=950 \end{cases}\qquad \qquad \stackrel{\textit{substituting on the 2nd equation}}{55a+80\left( \boxed{15-a} \right)=950} \\\\\\ 55a+1200-80a=950\implies -25a+1200=950\implies -25a=-250 \\\\\\ a=\cfrac{-250}{-25}\implies \blacktriangleright a = 10\blacktriangleleft \\\\\\ \stackrel{\textit{since we know that}}{b=15-a\implies }b=15-10\implies \blacktriangleright b=5 \blacktriangleleft$

Four of the angles of a pentagon measure 85, 110, 135, and 95. Find the measure of the missing angle.

_______________

Sum of the angles of a n-sided polygon:

$\mathsf{S_n=180^\circ\cdot (n-2)}$

In this question, we have a pentagon, so

$\mathsf{n=5,}$

then

$\mathsf{S_5=180^\circ\cdot (5-2)}\\\\ \mathsf{S_5=180^\circ\cdot 3}\\\\ \begin{array}{lcl}
\!\!\!\mathsf{S_5=540^\circ}&\longleftarrow&\textsf{sum of the measures of the internal}\\
&&\textsf{angles of a pentagon.}
\end{array}$

Let $\mathsf{x}$ be the measure of the missing angle. So,

$\mathsf{85^\circ+110^\circ+135^\circ+95^\circ+x=S_5}\\\\
\mathsf{425^\circ+x=540^\circ}\\\\
\mathsf{x=540^\circ-425^\circ}\\\\
\mathsf{x=115^\circ}\quad\longleftarrow\quad\textsf{measure of the missing angle.}$

I hope this helps. =)

You are a space alien. You visit planet Earth and abduct 97 chickens, 47 cows, and 77 humans. Then, you randomly select one Eart

Arte-miy333 [17]

Chicken probability is 97/(97+47+77)=97/221=43.89%
Cow probability is 47/221=21.27%
Human probability is 77/221=34.84%
