How can knowing the slope and y-intercept help you graph an equation?
Answer:
To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line.There are two important things that can help you graph an equation, slope and y-intercept.SlopeWe're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes." On the coordinate plane, the steepness, or slant, of a line is called the slope. Slope is the ratio of the change in the y-value over the change in the x-value. Carpenters and builders call this ratio the "rise over the run." Using any two points on a line, you can calculate its slope using this formula.help!!!!!!!!!!!!! Please

Find x
This is a kite from geometry
Answer:
x=6
Step-by-step explanation:
Solve for x.
5x-15 = 2x+3
(Move the 2x to the other side of the equation.)
3x-15= 3
(Move the 15 to the right side of the equation.)
3x=18
(Divide both sides by 3 to isolate the variable.)
x=6

Write an equation in the form y=Mx+b to model the given representation
Answer:
y= 20x +30
Step-by-step explanation:
y - intercept of the graph is 30
Slope of the graph is [tex]\frac{20}{1}[/tex]
Answer:
y = 20x + 30
Step-by-step explanation:
y=mx+b
b value = y-intercept, so you find where the line crosses the y-axis.
Find point at (0,30); b = 30
m value = rise/run (rise over run) (y/x)
find the next point that the graph intersects at and count add to it to find 30.
the closest point is at (-1,10)
go back to rise/run
30-10 = 20
0-(-1) = 1
20/1 =20 is your m value
plug m value and b value into equation to form your line.
y=20x+30

A line segment has endpoints at (1, 3) and (3,1). If the line segment is translated 2 units up and 2 units to the right, what are the new coordinates of the second point? a.(1, 3) b. (5, 3) c. (3, 3) d.(5, 1 )
Answer:
B: (5,3)
Step-by-step explanation:
The second point is (3,1)
2 units up is +2
2 units right is also + 2
So the new coordinates will be;
(3 + 2, 1 + 2) •= (5,3)

3/8x−1/3x+6=x find x
Step-by-step explanation:
3/8x-1/3x+6=x
(3(3x)-1(8x))/24=x-6
(9x-8x)=24(x-6)
x=24x-24×6
x=24x-144
144=24x-x
23x=144
x=144/23
During a catered lunch, an average of 4 cups of tea are poured per minute. The lunch will last 2 hours. How many gallons of tea should the cateree bring if there are 16 cups in one gallon?
Answer:
30 gallons (that’s a lot of tea!)
Step-by-step explanation:
Hi there!
we know that there are 60 minutes in an hour, 120 in 2 hours.
If 4 cups are poured every minute, we multiply 4 by the number of minutes in 2 hours, 120.
now we have 480 cups. However, they asked for gallons. They already give how many cups are in a gallon, 16, so all we have to do is divide 480 by 16 to find the amount of gallons needed.
480/16 = 30 gallons!
I hope this helped!
Answer:
30 gallon
Step-by-step explanation:
first you count up how many minutes is in 1 hour mutilply it by 2 if 4 cups were poured every minute and there's 16 cups per gallon you take 120 being 2 hours in minutes take 120 multiply it by 4 bc that's how man cups are poured per minute and that 480 cups 480 cups divided my 16 which is how many cups is in a gallon and you get 30

log3(3^4)=x
Step-by-step explanation:
log3(3^4) = x.
=> 3^x = 3^4
=> x = 4.
what is the value of?
Answer:
70 degrees
Step-by-step explanation:
Since the angles of a triangle have to add up to 180 degrees, you know that the third angle of the triangle on the left would be 180 - 60 - 65 = 55 degrees. Then, since the angles on a straight line have to add up to 180 degrees you could find one of the two missing angles of the second triangle by doing
180 - 55 - 50 = 75.
Then, you have 2 out of the 3 angles of the triangle on the right and you can find the third, the ?, by doing 180 - 75 - 35 = 70 degrees
Andre's school orders some new supplies for the chemistry lab. The online store shows a pack of 10 test tubes costs $4 less than a set of nested beakers. In order to fully equip the lab, the school orders 12 sets of beakers and 8 packs of test tubes.
1. Since t is in terms of b from the first equation, this expression can be substituted into the second equation where t appears. Write and equation that shows this substitution.
2.solve the equation for b
3.How much did the school pay for a set of beakers? For a pack of text tubes?

What is the Y-INTERCEPT of the line y = 3x - 5
Answer:
(0,-5)
Step-by-step explanation:
In y = mx+b, b is the y-value of the y-intercept.
Here, b = -5.
Note: the y-intercept is a POINT, not a value.
Step-by-step explanation:
Hey there!
Given equation is; y= 3x-5.
Comparing the equation with y= mx+b, where "b" is y-intercept. we get;
y-intercept= -5
Therefore, y-intercept of the equation is"-5".
Hope it helps...
