If Jen babysits for 3 hours, she earns $12; and for 5 hours she earns $20.
Graph this linear relationship with x =#hours, and y = dollars earned.
How much does she earn per hour?
Answer:
To graph this linear relationship, we can plot two points on a coordinate plane: (3,12) and (5,20). These points represent the number of hours Jen babysits (x-coordinate) and the amount of money she earns (y-coordinate).
We can connect these two points with a line to form a linear equation that represents the relationship between the number of hours babysat and the money earned.
The slope of this line can be found using the formula: (change in y) / (change in x) = (20-12) / (5-3) = 8/2 = 4
Therefore, Jen earns $4 per hour by babysitting.
It is important to note that this is a linear relationship, and the earnings are proportional to the number of hours babysat. This means that for any number of hours babysat, the earnings can be found by multiplying that number by $4.
Step-by-step explanation:
Answer: For every hour she babysits, she earns $4. ✅
Step-by-step explanation:
To graph the linear relationship, we can start by plotting two points: (3,12) and (5,20).
This represents that for 3 hours of babysitting, Jen earns $12, and for 5 hours of babysitting, she earns $20.
We can then use these points to find the slope of the line, which is the rate at which her earnings change as the number of hours increases.
The slope can be found by using the formula: (change in y) / (change in x) = (20 - 12) / (5 - 3) = 8/2 = 4
This means that for every hour she babysits, she earns $4.
So, the equation of the line is : y = 4x + b
Where b is the y-intercept, which can be found by substituting one of the points into the equation.
For example, by substituting (3,12) in the equation:
12 = 4(3) + b
b = 0
So, she earns per hour $4. ✅
Write a ratio to represent the scale used in the drawing.
The ratio of these two figures would be for every 1cm in image A, in image B there are 2cm. So the ratio would be 1:2
What is ratio?The ratio is a mathematical term that refers to the quantified relationship between two magnitudes that reflects a proportion, that is, the ratio is the way of representing the proportion between two magnitudes. In this case, the ratio refers to the length of each side of these triangles and their relationship to each other.
According to the above, the ratio could be 1:2 because the larger triangle has lengths that are twice the lengths of the sides of the smaller triangle. For example, the left side of the small triangle is 6 cm, while the left side of the large triangle is 12 cm.

if s1 and s2 are subspaces of rn of the same dimension, then s1 = s2.
This statement is false. Two subspaces of R^n can have the same dimension but still be different.
Here are a few bullet points that elaborate on this:
A subspace is a subset of a vector space that is closed under addition and scalar multiplication.The dimension of a subspace is the number of vectors in a basis for the subspace.Two subspaces of R^n can have the same dimension if they have the same number of vectors in a basis, but the vectors themselves could be different.For example, the subspace of all multiples of the vector (1,0) and the subspace of all multiples of the vector (0,1) both have dimension 1, but they are different subspaces because they contain different sets of vectors.The subspace of all multiples of the vector (1,0) is the set of all vectors of the form (x,0) and the subspace of all multiples of the vector (0,1) is the set of all vectors of the form (0,y) and these two sets are different.Therefore, the statement "If s1 and s2 are subspaces of R^n of the same dimension, then s1 = s2" is not true in general.

What is compound inequality?An inequality that combines two other inequalities by using either "and" or "or" is referred to as a compound inequality. In certain cases, "and" won't be stated explicitly, but it is still understood. For instance, 1 x 3 simply means "x > 1 and x 3". However, a compound inequality using "or" is always explained in detail using "or." Compound inequalities may be divided into two categories: conjunction and disjunction.
The given compound inequality is:
1 ≤ | x + 3 | ≤ 4
As the equation contains a mod sign, we can write the inequality as follows:
1 ≤ x + 3 ≤ 4, and
1 ≤ - x - 3 ≤ 4
Simplify the first equation:
1 ≤ x + 3 ≤ 4
Subtract 3 from both the sides of the equation:
1 - 3 ≤ x + 3 - 3 ≤ 4 -3
-2 ≤ x ≤ 1
Simplify the second equation:

Add 3 on both sides of the equation:

What does a math ratio mean?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.

To find out the number of calories in 1/2 cup, we can set up a proportion using the information we have:
(1/2 cup) / x = (3/4 cup) / 60
we can cross-multiply to get:
x = (1/2 cup) * (60 / (3/4 cup))
