8 0

Answer:

80,000 people.

Step-by-step explanation:

Let's use a ratio:

voters : people overall

4 : 10

80 : 200

80,000: 200,000

80,000 out of 200,000 people voted.

Misty correctly determined the equation of the linear function represented by the table of values below to be y = negative 2 x +

olasank [31]

Answer:

Step-by-step explanation:

y = mx + c

m = (y2 - y1 )/ (x2 - x1)

using (1 , 7) & (2,5)

y2 = 5 y1 = 7 so y2 -y1 = -2

x2 = 2 x1 = 1 so x2 - x1 = 1

m - -2/1 = -2

y = -2x + c

when x =1 y = 7

so 7 = -2 + c

=> c =9

y = -2x + 9

if ordered pairs (2, 5) and (4, 1) used

m = (1-5)/(4-2)

=> m = -4/2

=> m = -2

y = -2x + c

for x =2 y =5

5 = -2*2 + c

=> c = 9

y = -2x + 9

she would have got same equation

-5n+8= -7 in two-step equations-integers

Paha777 [63]

Answer:

n=3

Step-by-step explanation:

So the question we are to solve is to be solved by collecting like terms and by division

So let's solve the question

-5n+8=-7

So let's solve

-5n+8=-7

Substrate 8 from both sides

-5n=-15

So let's make n the subject of formula by dividing both sides by -5

n=3

Therefore the final answer for the given question is 3

What is the equation of the quadratic graph with a focus of (3, 1) and a directrix of y = 5?

telo118 [61]

Answer:

$f(x)=-\frac{1}{8}(x-3)^2+3$

Step-by-step explanation:

We want to find the equation of the parabola with a focus of $(3,1)$ and directrix $y=5$ .

Considering the directrix, the quadratic graph must open downwards.

The equation of this parabola is given by the formula,

$(x-h)^2=4p(y-k)$ , where $(h,k)$ is the vertex of the parabola.

The axis of this parabola meets the directrix at $(3,5)$ .

Since the vertex is the midpoint of the focus and the point of intersection of the axis of the parabola and the directrix,

$h=\frac{3+3}{2}=3$ and $k=\frac{5+1}{2}=3$ .

The equation of the parabola now becomes,

$(x-3)^2=4p(y-3)$ .

Also $|p|$ is the distance between the vertex and the directrix.

$|p|=2$

This implies that $p=-2\:or\:2$ .

Since the parabola turns downwards,

$p=-2$ .

Our equation now becomes,

$(x-3)^2=4(-2)(y-3)$ .

$(x-3)^2=-8(y-3)$ .

We make y the subject to get,

$y=-\frac{1}{8}(x-3)^2+3)$ .

This is the same as

$f(x)=-\frac{1}{8}(x-3)^2+3)$ .

A school is arranging a field trip to the zoo. The school spends 635.85 dollars on passes for 43 students and 2 teachers. The sc

aalyn [17]

Answer:

$22.67

Step-by-step explanation:

The school spends 635.85 dollars on passes for 43 students and 2 teachers, then the school spends

$\$635.85 :(43+2)=\$14.13$ per person.

The school also spends 367.22 dollars on lunch for just the students, so the school spends

$\$367.22 :43=\$8.54$ per person.

In total, a pass and lunch for each student was spent

$\$14.13+\$8.54=\$22.67$
