Answer:

Step-by-step explanation:

The two dots on the bottom of this figure define the base of a triangle. If we now use a compass to draw the blue arcs on either side, as shown, the arcs will intersect at two points. A straight line drawn through these two points will be perpendicular to the base. The triangle will be isosceles and could be (but doesn't have to be) equilateral.

Find a quadratic model for the set of values: (-2, -20), (0, -4), (4, -20). Show your work.

Ivahew [28]

Ok... so this question can be solved by using simultaneous equations.

Use the general from of a parabola

$y = ax^2 + bx + c$

you know the value of c, the y-intercept... y = -4

which means the equation is

$y = ax^2 + bx - 4$

now use the other 2 points to get 2 equations in 2 unknowns

(-2, -20) just substitute

$-20 = (-2)^2a + (-2)b - 4 ~~~or~~~ -20 = 4a - 2b - 4$

this becomes

$4a - 2b = -16$

now the other equation using (4, -20)

The simplified form is

VikaD [51]

Answer:

500

Step-by-step explanation:

The problem statement tells you ...

300 = 0.60×voters

Dividing by the coefficient of the variable gives ...

300/0.60 = voters = 500

500 students voted in the election.

Answer:

$PO=86.2\\ OM=23.8\\$

Step-by-step explanation:

To preface, your figure is going to be a line segment, with $O$ as your midpoint, in between points $P$ & $M.$

With that being said:

$PO+OM=PM$

Identify your values:

$PO=7y+12\\OM=3y-8\\PM=110$

Substitute the values into the first equation:

$7y+12+3y-8=110$

Combine like terms:

$10y+4=110$

Subtract $4$ from both sides of the equation:

$10y=106$

Divide by the coefficient of $y$ , which is $10$ :

$y=10.6$

Substitute $10.6$ for $y$ in segments $PO$ & $OM$ :

$PO=7(10.6)+12$

$OM=3(10.6)-8$

$PO=74.2+12$

$OM=31.8-8$

Solve:

$PO=86.2$

$OM=23.8$

Check your answers by substituting:

$PO+OM=PM$

$86.2+23.8=110$
