Answer:
y = -2/3(x) - 8
Step-by-step explanation:
y = mx + b
y = -2/3(x) + b
given: (-3, -6) x=-3 y=-6
-6 = -2/3(-3) + b
-6 = 2 + b
b= -8
so..
y = -2/3(x) - 8

If the ratio of A to B is 3 : 4, and the ratio of B to C is 2 : 3, what is the value of A when C is 5?
If the ratio of A to B is [tex]3 : 4[/tex], and the ratio of B to C is [tex]2 : 3[/tex], then the value of A when C is [tex]5[/tex] is [tex]2.5[/tex].
In the given question,
The ratio of A to B is [tex]3 : 4[/tex].
The ratio of B to C is [tex]2:3[/tex].
We have to find the value of A.
It is given that the value of C is [tex]5[/tex].
The given ratios are,
A : B [tex]=3 : 4[/tex]
B : C [tex]=2:3[/tex]
As we can see that the ratio of B is not same in both ratio so we first equal the ratio of B.
We can equal the ratio of B by multiplying [tex]2[/tex] on both side in the ratio of
B : C.
B : C [tex]=2\times2:3\times2[/tex]
After multiplying we get
B : C [tex]=4:6[/tex]
As given in the question that C [tex]=5[/tex].
They given in the ratio which means there have any number in the multiple of ratio. That which we can get real value from the ratio.
So we used [tex]x[/tex] as a multiple of ratio.
And the ratio of C is [tex]6x[/tex].
So we get that
[tex]6x=5[/tex]
Hence the value of [tex]x=\frac{5}{6}[/tex].
Now finding the value of A.
The ratio of A is [tex]3x[/tex].
And the value of [tex]x=\frac{5}{6}[/tex].
Now putting the value
A [tex]=3\times\frac{5}{6}[/tex]
A [tex]=\frac{5}{2}[/tex]
A =[tex]2.5[/tex].
The value of A is [tex]2.5[/tex].
Hence, if the ratio of A to B is [tex]3 : 4[/tex], and the ratio of B to C is [tex]2 : 3[/tex], then the value of A when C is [tex]5[/tex] is [tex]2.5[/tex].

It is given that ∠1 ≅ ∠3 and ∠1 = ∠4 and ∠3 = ∠6 as of vertically opposite angles, therefore ∠6 ≅ ∠4 too.
What is vertically opposite angles?Vertical angles, also known as vertically opposite angles, are formed when two lines cross each other at an angle that is opposite to it. Angles that are vertically opposite to one another are always equal to one another.
A vertical angle and the angle to which it is adjacent are also supplementary angles; that is, they add up to 180 degrees. As an illustration, if two lines intersect to form an angle, say X=45°, then the opposite angle is also 45°. And angle X's neighbor will have a measure of 180 minus 45, or 135 degrees.
Two lines are said to intersect when they come together at a single point in a plane. They are referred to as parallel lines when they do not intersect anywhere in a plane.
We have given that ∠1 ≅ ∠3
We can see that ∠1 = ∠4 as they are vertically opposite angles.
Also ∠3 = ∠6 as they are vertically opposite angles.
Thus, It is given that ∠1 ≅ ∠3 and ∠1 = ∠4 and ∠3 = ∠6 as of vertically opposite angles, therefore ∠6 ≅ ∠4 too.

If the speed limit is 80kilometers per hour and Elena’s mom was driving 75 miles per hour was she speeding by how m,uch
Elena's mom was speeding up by 25.29 miles/h.
What is unit conversion?
Conversion of units is the conversion between different units of measurement for the same quantity.
Given is the speed limit of 80 kilometers per hour.
To convert from kilometers per hour to miles per hour, divide the measurement in km/h by 1.609344.
Therefore, in miles per hour we can write -
80 Km/h = (80/1.609344) = 49.71 miles
75 - 49.71 = 25.29 miles/h
Therefore, Elena's mom was speeding up by 25.29 miles/h.

The number of days Ximena can afford to rent while staying within her budget is 4 days.
Given that, a rental car company charges $46.75 per day to rent a car and $0.13 for every mile driven.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
We know that it costs $0.13 for every mile driven and we plan to drive 100 miles, that means we can set the inequality as:
46.75x + 0.13(100) ≤ 200
46.75x + 13 ≤ 200
Rearranging the inequality so we have the variable alone on one side, we get:
46.75x ≤ 187
Divide both sides by 46.75 to get x alone
x ≤ 4

Expression:
An expression is a mathematical statement that does not contain an equal sign. It cannot be solved for unless the value of the variable is given.
Given,
Here we have the expression [tex]\frac{5^{-10}}{5^{4}5^{0}}[/tex]
Now we need to find the equivalent expression for this one.
In order to find the equivalent expression first we have to simplify the given expression.
For that we have to use the exponent rule,
1) Product of powers rule
When we multiplying two bases of the same value, keep the bases the same and then add the exponents together to get the solution.
2) Quotient of powers rule
When we dividing two bases with same value, keep the base the same, and then subtract the exponent values.
3) Negative exponent rule.
While we have the negative exponent then we have to convert them into fraction.
Based on the rule 1, we have simplify the denominator as,
[tex]\frac{5^{-10}}{5^{4}5^{0}}=\frac{5^{-10}}{5^{4+0}}\\\\= > \frac{5^{-10}}{5^{4}}[/tex]
Now we have to apply the rule (2), then we get,
=> 5⁻¹⁰⁻⁴

y = 2x+1 how do I solve this?
Solving an inequality, it is found that the interval over which the function y = 2x + 1 is positive is given by:
(-1/2, ∞).
When a function is positive and when it is negative?To verify if the function is positive or negative, we have to look at the graph of the function relative to the x-axis, as follows:
A function is positive when it is above the x-axis, that is, if y > 0, as the x-axis represents y = 0.A function is negative when it is below the x-axis, that is, if if y < 0.In the context of this problem, the function is given by:
y = 2x + 1.
We want to find when the function is positive, hence we have to solve this following inequality:
y > 0
2x + 1 > 0
2x > -1
x > -1/2.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
There are two kinds of equations: identities and conditional equations. An identity is true for all values of the variables.
Given equation -

If a student claims that 3.8¯ is an irrational number because it is a non-terminating decimal, then, he/she is incorrect as 3.8¯ can be represented as a fraction which is (35/9).
As per the question statement, a student claims that 3.8¯ is an irrational number because it is a non-terminating decimal.
We are required to determine if the claim is correct or incorrect, and if the claim is correct, then we will have to justify our answer, while if it is incorrect, we will have to determine the fraction that is equal to 3.8¯.
To solve this question, let us first try to convert our concerned decimal 3.8¯ into its equivalent fraction.
Now, 3.8¯ = 3.888...
Let us assume a random variable "x" such that, 3.8¯ = x = 3.888...
Then, 10x = (10 * 3.888...) = 38.888...
Now, [(10x - x) = {(38.888...) - (3.888...)}]
Or, (9x = 35)
Or, x = (35/9)
That is, the non-terminating decimal 3.8¯ can be converted to a fraction which is equal to (35/9).
Hence, the student's claim that that 3.8¯ is an irrational number because it is a non-terminating decimal is incorrect.

74.5645 miles is 120 kilometers per hour.
Both kilometers and miles represent units used to measure distance, and their magnitudes are comparable. The only distinction left is in the length units because both speed units have a time dimension that is measured in hours. A kilometer is a unit first from the metric system, whereas the mile is a part of something like the imperial unit system, which is used in many nations like the United States as well as the United Kingdom.Although it is a more recent measurement, the mile does have a lengthy history, going at least as far back as the Romans.The Roman mile was approximately 5,000 feet long, as well as additional miles with differing lengths in various locales and eras, such as the English, Irish, and Italian miles.Divide the speed of the vehicle by 1.609 to get an approximation.
