Use the elimination method to solve the system of equations. 5x + 2y = −45x + 2y = −4 −5x + 3y = 19−5x + 3y = 19 (−2, 3)(−2, 3) There is no solution. There are an infinite number of solutions. (−4, 6)
What is the solution set?
3.3x−11.6>18.1
Enter your answer in the box.
Please answer fast thanks!
The solution set is (9, ∞).
To solve the inequality 3.3x-11.6>18.1, we need to isolate the variable x.
First, we can add 11.6 to both sides of the inequality to get 3.3x>29.7.
Then, we can divide both sides by 3.3 to solve for x: x>9.
We can express the solution set using interval notation as (9, ∞).
Therefore, The solution set is (9, ∞).
The solution set for the inequality 3.3x - 11.6 > 18.1 is x > 9, meaning x is greater than 9.
To solve the inequality 3.3x - 11.6 > 18.1, you can follow these steps:
1. Add 11.6 to both sides to isolate the term with x:
3.3x - 11.6 + 11.6 > 18.1 + 11.6
3.3x > 29.7
2. Now, divide both sides by 3.3. Remember, when you divide by a positive number, the inequality sign remains the same:
[tex]\[ \frac{3.3x}{3.3} > \frac{29.7}{3.3} \][/tex]
[tex]\[ x > \frac{29.7}{3.3} \][/tex]
x > 9
So, the solution set for the inequality 3.3x - 11.6 > 18.1 is x > 9.
Which number is written in scientific notation?
6x10^11
12x10^-8
0.2x10^5
8x7^2
Answer: [tex]6\times10^{11}[/tex]
Step-by-step explanation:
We know that the scientific notation is a technique to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10]and powers of ten.
[tex]6\times10^{11}\\\text{ It is in scientific form}\\\\12\times10^{-8}\\\text{It is not in scientific form, since} 12 >9\\\\0.2\times10^5\\\text{It is not in scientific form, since }0.2<1\\\\8\times7^2\\\text{ It is not in scientific form, since power of 10 is not there}[/tex]
Hence, the number written in scientific notation is [tex]6\times10^{11}[/tex]

The angles ∠2 = 135°, ∠3 = 135°, ∠4 = 45°, ∠5 = 45°, and ∠6 = 135° (all are in degrees)
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
The angle ∠1 = 45° is given. And the diagram is shown.
Types of the angles are as follows;
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.Vertically opposite angle - When two lines intersect, then their opposite angles are equal.Alternate angle - If two lines are parallel then the third line will make z -angle and z-angles are equal angles with the parallel lines.∠1 + ∠2 = 180° (Supplementary angle)
45° + ∠2 = 180°
∠2 = 135°
∠1 = ∠5 = 45° (Corresponding angle)
∠2 = ∠6 = 45° (Corresponding angle)
∠1 = ∠4 = 135° (Alternate angle)
∠2 = ∠3 = 135° (Alternate angle)

Solve the equation
Final answer:
To solve the system of equations, we first expressed x in terms of y from the first equation and substituted it into the second equation. After simplifying, we solved for y and then substituted back into the first equation to find x. The solution is x = 5/3, y = -1.
Explanation:
To solve the system of equations 3x = -5y and 6x - 7y = 17, one can use the method of substitution or elimination. We'll use elimination for this example. First, observe that the first equation can be rewritten to solve for x in terms of y:
3x = -5y
x = -5y/3
Let's substitute this expression for x into the second equation:
6(-5y/3) - 7y = 17
-10y - 7y = 17
-17y = 17
y = -1
Now substitute y back into the first equation to find x:
3x = -5(-1)
3x = 5
x = 5/3
The solution to the system of equations is x = 5/3, y = -1.

The amount of money that Charlie saves each week is directly proportional to the amount he earns. Last week Charlie saved $32 on his earnings of $512. At the same rate, how much will Charlie save this week on his earnings of $448?
Answer:
$28.
Step-by-step explanation:
Let y represent of saved money and x represent amount of earned money.
We have been given that the amount of money that Charlie saves each week is directly proportional to the amount he earns.
We know that two proportional quantities are in form [tex]y=kx[/tex], where, k is constant of proportionality.
Substitute given values and solve for k:
[tex]32=k*512[/tex]
[tex]\frac{32}{512}=\frac{k*512}{512}[/tex]
[tex]\frac{1}{16}=k[/tex]
To find amount of saved money, we will substitute [tex]k=\frac{1}{16}[/tex] and [tex]x=448[/tex] in our equation.
[tex]y=\frac{1}{16}\cdot 448[/tex]
[tex]y=28[/tex]
Therefore, Charlie saved $28 in the given week.

ratios equivalent to 2:6.
The ratios equivalent to 2:6 are: 9:3 and 7:21
The given ratio is [tex]\(2:6\)[/tex]. To find equivalent ratios, you can multiply or divide both parts of the ratio by the same non-zero number. Let's analyze the options:
1. 10:7
To check if this is equivalent to 2:6, divide both parts by 2:
[tex]\[\frac{10}{2} : \frac{7}{2} = 5: \frac{7}{2}\][/tex]
This is not equivalent.
2. 9:3
To check if this is equivalent to 2:6, divide both parts by 3:
[tex]\[\frac{9}{3} : \frac{3}{3} = 3: 1\][/tex]
This is equivalent.
3. 7:21
To check if this is equivalent to 2:6, divide both parts by 7:
[tex]\[\frac{7}{7} : \frac{21}{7} = 1: 3\][/tex]
This is equivalent.
Therefore, the ratios equivalent to 2:6 are:
2:6
9:3
7:21
