find the zero for f (x)=80-10x

Answer:

-To find the cost of one gallon of gas in Toronto, you have to multiply the cost of one liter of gasoline for 3.8 as you know that there are 3.8 liters in one gallon:

$0.91*3.8=$3.46

This means that a gallon of gas cost $3.46 in Toronto.

-$3.46-$2.29=$1.17

Considering that one gallon of gasoline cost $2.29 in Buffalo and $3.46 in Toronto, the cost is greater in Buffalo. The cost is greater by $1.17.

Answer: the greatest Common Factor (GCF) is:   2

Step-by-step explanation:

To get the Greatest  Common Factor (GCF) of 2 and 72 we need to factor each value first and then we choose all the copies of factors and multiply them:

Given:

The endpoints of MN are located at M (-4, 4) and N (2,-2).

Point P divides the line segment MN such that MP: PN = 2: 1

To find:

The coordinates of point P.

Solution:

Section formula: If a point divides a line segment in m:n, then coordinates of that point are

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Point P divides the line segment MN in 2:1. So,

[tex]P=\left(\dfrac{2(2)+1(-4)}{2+1},\dfrac{2(-2)+1(4)}{2+1}\right)[/tex]

[tex]P=\left(\dfrac{4-4}{3},\dfrac{-4+4}{3}\right)[/tex]

[tex]P=\left(\dfrac{0}{3},\dfrac{0}{3}\right)[/tex]

[tex]P=(0,0)[/tex]

Therefore, the coordinates of the point P are (0,0).

y = mx + b - slope-intercept form

m- is the slope, the greater the slope the steeper the line, it gets flatter when is getting closer to zero

b- y-intercept, if be is positive it indicates vertical shift up, when negative- vertical shift down

Corresponding Angles

Step-by-step explanation:

Both [tex]\angle 4[/tex] and [tex]\angle 8[/tex] are Corresponding Angles, they are in the same side of the transversal line, and where a line crosses two other lines.

Step-by-step explanation:

<4 and <8 are corresponding angles because they are on the same side of the transversal and are at the same location and they are congruent meaning they are equal

Answer: x=

1/8y+5

Step-by-step explanation: Step 1: Flip the equation.

8x−40=y

Step 2: Add 40 to both sides.

8x−40+40=y+40

8x=y+40

Step 3: Divide both sides by 8.

8x

Answer: r≈6

Step-by-step explanation: Using the formula

C=2πr

Solving forr

r=C

2π=37.7

2·π≈6.00014

Answer:

The radius is 6

Step-by-step explanation:

The circumference of a circle is equal to pi times the diameter. The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius

C=2πr

r=C

2π=37.7

2·π≈6.00014

Answer:

50 yards.

Step-by-step explanation:

Since we know that 5 yards can make 2 costumes, we can divide 5/2 to find 2.5 yards are needed to make one costume. Then you can multiply 2.5*20 to get 50 yards needed for 20 costumes. Hope this helps :)

Answer:

Step-by-step explanation:

To find the time taken for an object to travel given it's velocity and distance covered we use the formula

[tex]time = \frac{distance}{speed} \\ [/tex]

From the question

distance = 480 miles

speed = 40 mi/h

So we have

[tex]time = \frac{480}{40} = \frac{48}{4} \\ [/tex]

We have the final answer as

Answer:

n = 12.5 or 25/2

Step-by-step explanation:

170-4n = 120

1. Subtract 170 from both sides to isolate -4n.

-4n = -50

2. Divide both sides by -4 to isolate the n.

n = 12.5 or 25/2

Hope this helped!

Answer:

12.5

Step-by-step explanation:

170 - 4n = 120

-170          -170

-4n         = -50

4n         =  50

  n         = 12.5

Answer:

Step-by-step explanation:

Given the dimension

Length of the rectangle = 8cm

Width = 5cm

Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m

If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;

5 * 10 = 50m

Hence the width of the new stage will be 50 m

Answer:

50m
