Following the recommended steps for solving equations, what should be your first step in solving the given
equation?
2x-3-4x-2x = -6
A. add 3 to both sides
B. subtract 4x from 2x
C. add 6 to both sides
D. add 4x to 2x
Answer:
The first step in solving the equation should be to add 3 to both sides.
Step-by-step explanation:
Adding 3 to both sides will cancel out the -3 on the left hand side of the equation, leaving only the 2x term. On the right hand side, adding 3 will cancel out the -6, leaving only 0. This will give you the equation 2x = 0, which is much easier to solve.

choose the equation below that represents the line passing through the point (-2,-3) with a slope of -6
The equation of the line is: y + 3 = -6(x + 2) [point-slope form] or y = -6x - 15 [slope-intercept form].
How to Write the Equation of a Line?Given a point (-2, -3) and a slope (m) of -6, you can write the equation of the line in point-slope form by substituting (a, b) = (-2, -3) and m = -6 into y - b = m(x - a):
y - (-3) = -6(x - (-2))
y + 3 = -6(x + 2) [point-slope form]
Rewrite in slope-intercept form as:

Answer:
Hello! The answer to your question is [tex]\sqrt{29}[/tex], or approximately 5.39.
Step-by-step explanation:
(Two methods)
Method 1:
To solve this problem, we will use the Pythagorean theorem. To create the triangle, you can connect all the points with lines. This will leave you with the base of the triangle as 2 and the leg as 5. We do not know the hypotenuse. Now, we can use the Pythagorean theorem formula:
[tex]a^2 + b^2 = c^2[/tex]
[tex]\sqrt{2^2 + 5^2 } \\= \sqrt{4 + 25} \\= \sqrt{29}\\or 5.39[/tex]
Now, we can substitute our values:
Method 2:
To solve this problem, we will use the distance formula:
[tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
Our points are:
A(-3, 1) and B(-1, -4)
Now, we substitute our values into the distance formula provided:
[tex]\sqrt{(-1 - (-3))^2 + (-4 - 1)^2} \\= \sqrt{(-1 + 3))^2 + (-5)^2} \\= \sqrt{(2)^2 + (-5)^2} \\= \sqrt{4 + 25} \\= \sqrt{29} \\or 5.39[/tex]

A pair of dice are tossed twice.Find the probability that both rolls give at most a sum of 8.
the probability that in bot rolls we have a sum of, at most, 8, is:
P = 47/ 1,296 = 0.036
How to find the probability?The pair is tossed twice. A pair of dice has 36 possible outcomes, so if we toss twice the pair, the total number of outcomes is:
36*36 = 1,296
Now if we define the outcomes as:
{dice 1 (roll1), dice2(roll1), dice 1 (roll2), dice2(roll2) }
The outcomes that give at most a sum of 8 are:
{1, 1, 1, 1}
{2, 1, 1, 1} ( 3 permutations)
{2, 2, 1, 1} ( 6 permutations).
{2, 2, 2, 1} ( 3 permutations)

The function g(x)=8(4x) is reflected across the x-axis to create f(x) What is the equation of f(x)?
Answer:
g(x)=-32x
Step-by-step explanation:
When something is reflected over the x-axis. The x doesn't change, it's the y that changes. So let's just generally say you have the point (x, y). Reflecting this over the x-axis means the y is changing, so it becomes (x, -y). And since the g(x) represents the y, you multiply the entire thing by -1. So the new equation becomes: g(x) = -(8(4x)) = -8(4x) = -32x. So the equation is g(x) = -32x or -8(4x) if you want to leave it like how it was before.
Erica earned a total of $15,450 last year from her two jobs. the amount she earned from her job at the store was $1250 more than four times the amount you earn from her job at the college how much. how much does he earn from her job at the college
If Erica earned a total of $15450 last year from both the jobs then he earns $2840 from college if she earned 1250 more than four times the amount from college from store.
Given Total amount earned=$15450,Amount earned from store is 1250 more than 4 times earned from college.
Amount from store forms an equation.
let the amount earned from college is x.
According to question:
Amount earned from store=4x+1250
Amount earned from college=x
Total amount earned=4x+1250+x
5x+1250=15450
5x=15450-1250
5x=14200
x=14200/5
x=2840
Put the value of x in 4x+1250 to get amount earned from store=4(2840)+1250=$12610.

. Describe the transformation of the function, y = x + 4, from y = x.
There are two interpretations we could go for:
Adding 4 to the end means we add 4 to each y coordinate (since y = x). This shifts the entire line 4 units upReplacing x with x+4 means the xy axis is shifted 4 units to the right. If the line y = x is held completely still while the axis moves, then it gives the illusion the line is moving 4 units to the leftCheck out the diagram below.
Point A on the red line y = x has two locations it could end up. If we follow method 1, then point A shifts upward to point B. Do this to every point on the red line and the entire red line shifts up 4 units.
Or if you decide to shift 4 units to the left (method 2), then point A moves to point C's location. Doing this to every point on the red line shifts the entire line 4 units to the left.

Y=2+4x
What does the y- intercept of this function represent?
the original height of the plant was 2mm. The correct option is the second one.
What does the y-intercept of the function represent?
We know that the function:
y = 2 + 4x
Represents the height of a plant in mm, as a function of x, the hours kepts in sunlight.
The y-intercept is the value that y takes when we evaluate in x = 0.
So, the y-intercept is the height of the plant when it is exposed to zero hours of light.
In this case:
y = 2 + 4*x
Evaluating in x = 0
y = 2 + 4*0 = 2
This means that the original height of the plant was 2mm. The correct option is the second one.

Step-by-step explanation:
since this is creating a right triangle you can use the Pythagorean theorem which is a^2 + b^2 = c^2, and by plugging in the one leg length and the hypotenuse length you get 14.8324 which rounds up to 14.8
The distance between the ground and the top of the ladder is 14.8 feet.
What is Pythagoras theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
Hypotenuse= 16 foot,
