Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptGiven equation:
[tex]3x-2y=-12[/tex]
To write the given equation in slope-intercept form, apply arithmetic operations to isolate the variable y.
Add 2y to both sides:
[tex]\implies 3x-2y+2y=-12+2y[/tex]
[tex]\implies 3x=2y-12[/tex]
Add 12 to both sides:
[tex]\implies 3x+12=2y-12+12[/tex]
[tex]\implies 3x+12=2y[/tex]
Switch sides:
[tex]\implies 2y=3x+12[/tex]
Divide both sides by 2:
[tex]\implies \dfrac{2y}{2}=\dfrac{3x+12}{2}[/tex]
[tex]\implies \dfrac{2y}{2}=\dfrac{3x}{2}+\dfrac{12}{2}[/tex]
[tex]\implies y=\dfrac{3}{2}x+6[/tex]
Therefore, the slope-intercept form of the given equation is:
[tex]y=\dfrac{3}{2}x+6[/tex]
where 3/2 is the slope, and 6 is the y-intercept

Jamie has 70 coins. They total $6.30. If they are only dimes and nickels find out how many of each she has.
Answer:
Jamie has 14 nickels and 56 dimes
Step-by-step explanation:
Start by identifying labels for the # of dimes and nickles. Lets use x for nickels and y for dimes.
From here you can make two formulas (x + y = 70) and (5x + 10y = 630) when you put them into a graphing calculator they should intersect at (14,56) which means the x = 14 and y = 56

Graph the line with a slope of 2/5 that goes through (3,1)
Answer:
[tex]y = \dfrac{2x}{5} - \dfrac{1}{5}[/tex]
Step-by-step explanation:
Given:
[tex]\bullet \ \ \text{Slope of line:}\ \dfrac{2}{5} \\\\ \bullet \ \text{Passes through:} \ (3, 1)[/tex]
To determine the equation of the line, we will use point slope form.
Formula of point slope form:
→ y - y₁ = m(x - x₁)Where "x₁" and "y₁" are the coordinates of the point and "m" is the slope.
Substitute the coordinates and the slope:
[tex]:\implies y - 1 = \dfrac{2}{5} (x - 3)[/tex]
Simplify the R.H.S:
[tex]:\implies y - 1 = \dfrac{2x}{5} - \dfrac{6}{5}[/tex]
Add 1 both sides:
[tex]:\implies y - 1 + 1 = \dfrac{2x}{5} - \dfrac{6}{5} + 1[/tex]
Simplify the equation:
[tex]:\implies y = \dfrac{2x}{5} - \dfrac{6}{5} + \dfrac{5}{5}[/tex]
[tex]:\implies \boxed{y = \dfrac{2x}{5} - \dfrac{1}{5}}[/tex]
Graphing the line on a coordinate plane:
In this case, we are already given a point (3, 1). We can simply plot the y-intercept [tex][\bold{\frac{-1}{5} }][/tex] on the coordinate plane. Then, we can draw a straight line through both points. It is suggested that you use a ruler to do so.
Graph attached**
Answer:
See attachment and explanation
Step-by-step explanation:
slope is x/y, which means for each x how many y's it moves by.
so,
2/5 means for every 2 x's it goes up by 5 y's.
so,
you take the point A and go right 2 and go up 5. That's the next point (5,6)
Same with the point other side of A. Go left 2 and go down 5. That's another point (1,-4)
Since, the slope 2/5 is positive, the line will be an increasing line. As shown in the attached image.

What is the translation of plane figures?A plane figure translation is an isometry that translates each position of the figure at a distance and in a direction indicated by the vector.
It is also regarded as a sort of transformation that involves sliding each point in a plane figure at an identical distance in a similar direction.

Stacey wants to buy 20 peaches that each weigh 4 oz. How much will Stacey need to pay for the peaches? HINT: There are 16 ounces in 1 pound.
Answer:
$14.00
Step-by-step explanation:
So, the 20 peaches all weigh 4 oz, and there are 16 oz in 1 pound. 16 oz divided by 4 is also equal to 4 oz, so we need to divide $2.80 by 4, which would be $0.70. That means that a 4 oz peach would be $0.70, so we multiply that by 20, which gives us $14.00, so Stacey will need $14.00 to buy 20 peaches that each weigh 4 oz.

A straw forms a cylinder with a length of 270 millimeters and a diameter of 6 millimeters. What is the volume of the straw in cubic millimeters? Round your answer to the nearest hundredth.
The volume of the cylindrical straw of diameter 6 mm and length of 270 mm is 7630.20 mm³
Volume of a cylinder
volume of a cylinder = πr²h
Therefore,
r = radius of the baseh = height of the cylinderHence,
radius = r = 6 / 2 = 3 mm
volume of the cylinder = 3.14 × 3² × 270
volume of the cylinder = 3.14 × 9 × 270
volume of the cylinder = 7630.2 mm³
Therefore, the volume of the straw is 7630.2 mm³

Betty sits 9 feet from the fulcrum and weighs 100 pounds. How far should Ginger sit if she weighs 125
pounds?
Answer:
7.2 feet
Step-by-step explanation:
Torque is calculated by T=Frsin(theta). Betty's total torque is 9 x 1000 (mg) = 9000. Since ginger weighs 125 pounds, 9000 = (125 x 10) x r. Solve for r and get 7.2 feet.

how many fluid ounces of juice did sofia buy?
Answer:
$0.14 per fl oz /// 256 fl oz of juice.
Step-by-step explanation:
The number of fluid oz per gallon = 128
2 gallons = 256 fl oz

I need help with 5/9 divided by 3/8
Answer:
40/27 or
1 and 13/27
Step-by-step explanation:
Use Keep-Change-Flip to divide fractions.
Problem:
5/9 ÷ 3/8
KEEP the first fraction, the 5/9, just copy it exactly, no changes.
CHANGE the ÷ to ×
5/9 ×
FLIP the second fraction, the 3/8. Flip it over (reciprocal)
5/9 × 8/3
Now do this problem. You can "cancel" (which is really dividing) or multiply straight across (top×top, bottom×bottom)
5/9 × 8/3
= 40/27
This cannot be reduced. It is a perfectly good answer just like this. But since there is a larger number on top, your teacher/class/book/program, might want you to change it to a mixed number.
40/27 = 1 13/27
