Please help! What’s the error in line 1 ?

Mathematics
1 answer:
sveticcg [70]3 years ago
6 0

Answer:

When you add variables with exponents, you do not add the exponents together.

The error -> y^2+2y^2=3y^4

In this case, they have added the exponent 2+2=4.

However, you do not add it. Instead, the answer should be 3y^2

What Is the slope of the line on the graph?
sashaice [31]

Answer:

1/2

Step-by-step explanation:

To find out this problem, you do rise over run to find the slope. First choose two points that are directly sitting on a line. I used (-2,1) and (0,2). Then count the rise, up 1, then the run, over two and that's how you get your answer. :)

Answer:

the possible line of best fit equation is;

y = 10x + 24

Step-by-step explanation:

Here, we want to get the approximate line of best fit

Mathematically, we have the general line of best fit as

y = mx + b

where m is the slope and b is the y-intercept

By joining the given lines, we can see that the y-intercept values fall a little below 30

This means that the possible y-intercept value is 24

Now, to get the slope value, we select any two points and use the slope equation

We can have (3,50) and (6,80)

Using the slope equation;

m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10

The equation is thus;

y = 10x + 24

The radius of a circle is 28 centimeters. What is the diameter?
MrMuchimi
Radius
is half of the circle
diameter
is the whole thing inside the circle
since it is a radius, and it is a half of the full circle, we need to double out that number, and multiply by 2.
so here, you said it is 28
take 28, and multiply by 2, if you do every thing correctly, you should get:
56
so then answer would be 56 centimeters.
Hope that this helps you!  =)

The solution set, all real numbers greater than or equal to one, proves which of the following inequality statements to be true?
Juliette [100K]

Answer:

-5x ≤ 6x - 11

Step-by-step explanation:

Solving inequalities involves the same steps as equations with the exception that when multiplying or dividing by a negative coefficient of the variable, the inequality sign will flip.  The solution to one of the inequalities given must be x ≥ 1.  Given this answer, you can solve each to find the matching inequality:

-5x ≥ 6x - 11 or -11x ≥ -11 or x ≤ 1 (flip the sign due to negative coefficient)

-5x ≤ 6x - 11 or -11x ≤ -11 or x ≥ 1 (flip the sign)

5x ≤ 6x + 11 or -x ≤ 11 or x ≥ -1

-5x ≤ 6x + 11 or -11x ≤ 11 or x ≥ -1
