The solutions from least to greatest are lesser x = -2 and greater x = 2/3 for the equation (2x +4)(3x -2)=0
An equation is collection of two or more expressions with an Equal sign
The given equation is (2x +4)(3x -2)=0
To find the solutions, we set each factor equal to zero and solve for x
2x + 4 = 0
Subtract 4 from both sides
2x = -4
Divide both sides by 2
x = -2
Now 3x - 2 = 0
Add 2 on both sides
3x = 2
Divide both sides by 3
x = 2/3
Therefore, the solutions from least to greatest are lesser x = -2 and greater x = 2/3

Identify the slope of the line given in the graph:
Which linear function has a negative slope?
Which linear function has the steeper slope?
Using linear function concepts, it is found that:
The slope of the line given in the table is of -1.5.The slope of the line given in the graph is of 0.67.The linear function in the table has a negative slope.Due to the higher absolute value of the slope, the function in the table has a steeper slope.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points, the slope is given by change in y divided by change in x, hence:
For the table, the slope is of m = (5.5 - 8.5)/(-1 - (-3)) = -1.5, which is a negative value.For the graph, the slope is of m = (2 - 0)/(0 - (-3)) = 0.67.Due to the higher absolute value of the slope, the function in the table has a steeper slope.

Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week. Elena starts with $10 in her savings account and adds $20 each week. After four weeks, who has more money in their savings account? Explain how you know.
Show your work.
Answer:
andre has more money
Step-by-step explanation:
Answer:
You need to write an equation for each.
For Andre, he has 100 dollars, and every week gets 5 dollars more. You add the 5 dollars, and Since you don't know how many weeks it has been, use a variable.
100 + 5w
For Elena, she has 10 dollars, and gets 20 each week.
10 + 20w
Now that you know that it has been 4 weeks, you can plug in 4 for the variable for weeks.
Andrew:
100 + 5(4) =120
Elena
10 + 20(4) ==90
Andrew has more money in this time.
To find when they have the same amount, equal their expressions to each other. This means that they will have the same amount (because they are equalled) and you can solve to find the variable, which means the weeks that they are equal at.
Bring the like terms to each side by canceling them out. Since you have positive 10, then subtract 10 to each side. You have 5w, so subtract 5w to each side.
90+5w=20w
90=15w
90÷15=6
6=w
The answer will simplify down to 6 weeks.
what is 5(n- 1/10) = 1/2
Answer:
1/5
Step-by-step explanation:
In order to find the answer, we need to isolate the "n."
Get 5 to the other side by dividing both sides by 5
(n-1/10)= 1/2 ÷(5)
Multiply the 2 and the 5 of the equation.
(n-1/10)= 1/10
Next, move the fraction on the left side, to the right.
n= 2/10
Reduce.

Given -2x+5y=15, determine the equation of the line of a dilation centered at the origin with a scale factor of
k=3
**MUST SHOW WORK FOR FULL CREDIT**
Answer:
Angle: A figure formed by two rays or line ... Time Period 3: Geometric Relationships & Properties, 15 blocks ... dilation of the polygon with that point as the center. Identify the scale factor that you used. G-SRT 2. Given two figures, use the ... the circle centered at the origin and ... Write an equation for a circle with a radius of 2.
Step-by-step explanation:
The equation of the line of dilation centered at the origin with a scale factor of k=3 is,
⇒ y' = (6/5)x + 3.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Now, To find the equation of the line of dilation centered at the origin with a scale factor of k=3,
we need to apply the dilation transformation to the given equation.
First, we need to rewrite the equation in slope-intercept form:
-2x + 5y = 15
5y = 2x +15
y = (2/5)x + 3
Now, we can apply the dilation transformation by multiplying the slope by the scale factor k = 3;
y' = k y
y' = 3 (2/5)x + 3
y' = (6/5)x + 3
Therefore, the equation of the line of dilation centered at the origin with a scale factor of k=3 is,
y' = (6/5)x + 3.

A bike shop sells rolling strollers for runners with babies, with a total of 28 in the store. Some of the strollers have 3 wheels and some have 4. If there are 100 wheels, how many 3-wheel strollers are there?
Answer:
12
Step-by-step explanation:
let x = number of 3 wheel stollers
let y = number of 4 wheel strollers
x + y = 28
y = 28 - x
3x + 4y = 100
3x + 4(28 - x) = 100
3x + 112 - 4x = 100

Solve the system of equations - 2x - y = 6 and — 7x - y = -4 by combining the equations.
Answer:
(2,-10)
x=2
y= -10
Step-by-step explanation:
To solve by combining the equations we first need to get everything in linear form.
For both equations we can simply just add y to both sides and then subtract the other number on the right side. Doing this gets us
-2x-6=y
-7x+4=y
We then set the two equations equal to each other and solve for y
-2x-6= -7x+4
add 7x and 6 to both sides and get
5x=10
x=2
Use this x value and plug it into any equation
let's do it on the first
-2(2)-y=6
Solve for y and get
-y=10
which means that
y= -10
