How do you find the equation of a graph
You find the equation of a graph by finding an equation with a
graph.
An electrician charges 50 to come to your house He also chrges 25 for each our he spends at your house The alectrician chrges you a total of 125 How many hours did he spend at your house
150=25x+50, solving 150-50=25x 100=25x 100/25=x x=4 hours
Jack cut a piece of wood that was 8 feet long into two pieces one piece is three times as long as the other how long in the shorter piece of wood
Let x be the length measure of the shortest piece of wood, and
3x the length measure of the other piece of wood. So we have:
x + 3x = 8
4x = 8 divide by 4 to both sides;
x = 2
The length measure of the shortest piece of wood is 2.
Three times a number decreased by fourteen is four
Rewrite the formula to solve for c
Mimi had 174 to buy tickets to a concert The adult tickets cost 10.50 and the student tickets cost 7.50 She bought 4 more student tickets than adult tickets How many student tickets did she buy
What formula expresses newton's second law of motion
The formula of Newton's second law is F=ma, for force( F) equals
the mass (m) times the acceleration (a).
What is the length of the rectangle if the area is 132 square feet and the width is 11 feet
A ship is traveling at an average velocity of 28 miles per hour How far will the ship travel in two days
Darren can get to work in 30 minutes The speed limit is 35 mph but there are three stop lights With the traffic and lights he can average 30 mph How far is he from work
(30 mph) x (1/2 h) = 15 miles
What is the width of the rectangle if the area is 132 square feet and the length is 12 feet
A conveyor belt carries filled bottles of milk to be packed The bottles are placed five feet apart on the belt If the belt is moving at a rate of two feet per second how many bottles will be packed
A plane flew nonstop from Dallas to Las Vegas The distance was 1350 miles and the plane averaged 300 miles per hour How long was the plane in the air
7x-4x plus 2x plus 5 equals 2x plus 14
7x-4x+2x+5=2x+14
5x+5=2x+14
3x=9
x=3
What is the range of 0 0 0 1 1 1 2 2 2 2 2 2
Thirty-two decreased by twice a number is less than eighteen
88 plus x equals 3 times x plus 22 solve for variable
88+x=3x+22
88=2x+22
66=2x
x=33
Find the slope of the line that passes through the points 0 0 and 2 4
3a plus 5 equals 5a plus 3
If 3a+5=5a+3, then:
3a+5 - 3a = 5a+3 - 3a
5=2a+3
5 - 3=2a+3 - 3
2=2a
a=1
What are coordinates used on
Does the graph of this line y-3x-5 have a negative slope or a positive slop
How long will it a train to travel 200 miles at the rate of 80 miles at the rate 80 miles per hour
two and a half hours, 200/80 = 2.5
Ordered pairs would be found in quadrant III of the coordinate plane
How do you get the answer 7 using only numbers -4-3-2-1
[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7
[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7
[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7
[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7
Does y12x 1 have a negative or positive slope
If you mean: y = 12x+1 then it has a positive slope of 12 and a
y intercept of 1
What is this equation in standard form. y -4x - 1
If you mean: y = -4x-1 then it is 4x+y+1 = 0 in standard
form
When the absolute value of the slope gets smaller the graph of a line gets what
When the slope of a line reaches zero it then will be parallel
to the x or y axes depending if its a positive or a negative
slope.
