86,000cm
To convert cm to metres you will need to divide it by 100.
So, 86,000/ 100 which is equal to 860m
Then, to convert it to km, you need to divide your answer by 1000
So, 860m / 1000 is equal to 0.86km
Thus the answer is 0.86km

Hope this helped

4 1/3 ÷ 2 3/5
first we need to make them improper fractions.
4 1/3 would be 13/3
2 3/5 would be 13/5
13/3 ÷ 13/5
13/3*5/13
13*5=45
3*13=39
45/39
1 6/39 = 1 2/13

Describe the transformation that takes f(x)=x+1 to g(x) = -x+4. Will Mark Brainliest.

lions [1.4K]

Answer:

Reflection across y axis

Translate up by 3 units

Step-by-step explanation:

Given

$f(x) = x + 1$

$g(x) = -x + 4$

Required

Describe the transformation from f(x) to g(x)

First, take a reflection of f(x) across the y axis.

So f(x) becomes f(-x)

$f(x) = x + 1$ when reflected

$f(-x) = -x +1$

Next, translate f(-x) up by 3 units to give g(x)

$g(x) = f(-x) + k$

Where

$k = 3$

$f(-x) = -x +1$

$g(x) = -x + 1 + 3$

$g(x) = -x + 4$

Hence, the transformation from f(x) to g(x) includes:

Reflection across y axis

A map in Connecticut is drawn to a scale where 2 inches on the map represents 35 miles. If Greenwich and stonington are 105 mile

eduard

Answer: 6 inches

Step-by-step explanation:

From the question, we are informed that a map in Connecticut is drawn to a scale where 2 inches on the map represents 35 miles.

If Greenwich and stonington are 105 miles from each other, to calculate their distance on the map will be:

Since 2 inches represent 35 miles, then: 1 inch = 35miles/2 = 17.5 inches.

Since 1 inch = 17.5 inches;

105 inches will then be: 105inches/17.5 inches = 6 inches

Therefore, 6 inches represent 105 miles.

What is 3y-12=4x+8 in Point-Slope form and graphed but the line needs to pass through (-2,4)

rodikova [14]

Answer:

The equation of the line in point slope form is equal to

$(y-4)=\frac{4}{3}(x+2)$

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a line in point-slope form is equal to

$y-y1=m(x-x1)$

we have

$3y-12=4x+8$

Convert to point slope form

Factor 3 left side and factor 4 right side

$3(y-4)=4(x+2)$

Divide by 3 both sides

$(y-4)=\frac{4}{3}(x+2)$

In this equation

the point is (-2,4)

the slope is $m=\frac{4}{3}$

using a graphing tool

The graph in the attached figure
