We are given the following expression:
[tex]9-k\div\frac{3}{4}[/tex]We are also given that k is equal to 2/3. So, we can substitute that into the expression:
[tex]9-\frac{2}{3}\div\frac{3}{4}[/tex]Due to order of operations, we have to do the division first, and then do the subtraction. To do division with fractions, we keep the first fraction the same and take the reciprocal of the second fraction. Then, we can multiply the two fractions. Let's do that:
[tex]9-(\frac{2}{3}\div\frac{3}{4})=9-(\frac{2}{3}*\frac{4}{3})=9-\frac{8}{9}[/tex]Now, we can do the subtraction:
[tex]9-\frac{8}{9}=\frac{81}{9}-\frac{8}{9}=\frac{73}{9}[/tex]Therefore, our answer is 73/9

solve x=y+4, where x=3
if x=3 we get
[tex]3=y+4\rightarrow y=3-4=-1[/tex]A circle has a center at (4, -7) and a radius of 4 units. What is the equation of this circle?
O (4)² + (y + 7)² = 16
O (x + 4)² + (y + 7)² = 4²
O(x-4)² + (y - 7)² = 16
O(x + 4)² + (y - 7)² = 4²
the equation for the circle with radius, r = 4 units and center =(4,-7)
will be (x-4)² + (y+7)² = (4)².
When the center and radius of a circle are known, how do you determine its equation?
Use the formula (x-a) ² + (y-b) ² = r ² to determine a circle's equation when you are aware of its radius and center. Here, stands for the circle's center, and is its radius. This equation is essentially a variant way of writing the general equation for a circle.
In this question,
we are given the center of our circle to be,
(4,-7) ≈ (a,b)
thus we are given,
a = 4
and b = -7
and we are given the radius to be 4units
substituting these values in the above equation,
(x-4)² + (y-(-7))² = (4)²
= (x-4)² + (y+7)² = (4)²
Hence the equation for the circle with radius, r = 4 units and center =(4,-7)
will be (x-4)² + (y+7)² = (4)².

Jena's income is $3800 a month, and she plans to budget 13 of her income for savings and 16 of her income for groceries.
What fraction of her income does she plan to spend each month on these two items together?
The fraction of Jena's income does she plan to spend each month on these two items together is 1/2
The fraction of her income does she plan to spend each month on the two itemsJena's income for the month = $3800Fraction of Jena's income for savings = 1/3Fraction of Jena's income for groceries = 1/6Amount of Jena's income spent on savings = 1/3 × $3800
= 1266.666666666666
Approximately,
= $1,266.67
Amount of Jena's income spent on groceries = 1/6 × $3800
= 633.3333333333333
Approximately,
= $633.33
Amount spent on the two items = $1,266.67 + $633.33
= $1900
Fraction of Jena's income spent on the two items = 1/3 + 1/6
= (2+1) / 6
= 3/6
= 1/2
So therefore, Jena spent 1/2 of her income on savings and groceries.

When the linear correlation coefficient is 1 there is a perfect positive linear relation between the two variables. Scatter diagram would contain points that all lie on a line with a positive slop.
What is coefficient coorelation?A correlation coefficient is a statistical indicator of how well changes in one variable's value predict changes in another. When two variables are positively linked, the value either rises or falls together.
A correlation coefficient is a metric that expresses a correlation, or a statistical link between two variables, in numerical terms. Two columns of a specific data set of observations, sometimes referred to as a sample, or two parts of a multivariate random variable with a known distribution may serve as the variables.
The strength and direction of the linear links between two sets of variables are evaluated using correlation coefficients. Use Pearson's correlation coefficient if both variables are regularly distributed; otherwise, use Spearman's correlation coefficient.

What’s the slope I need help
Answer:
-8/3
Step-by-step explanation:
You want the slope of the line shown in the graph.
Slope from point coordinatesWhether counting grid squares on the graph, or using the slope formula, it is convenient to choose two points on the grid where the line crosses the intersection of grid lines.
It appears, the line passes through grid points (1, 4) and (4, -4). Using the slope formula, we find the slope of the line to be ...
m = (y2 -y1)/(x2 -x1)
m = (-4 -4)/(4 -1) = -8/3
The slope of the line is -8/3.
Counting grid squaresThe slope is the ratio of "rise" to "run" for the line. From the two points we see where the line crosses grid intersections, we have a "rise" of -1 from y=4 to y=-4, and a "run" of 3 from x=1 to x=4.
rise/run = -8/3 = slope of the line

A man realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-tax total. If the after-tax total was $1,253.07, and the tax rate in the area is 7.1%, what was the pre-tax subtotal?
To answer this question, we can proceed as follows:
1. We have that the after-tax total was $1,253.07.
2. We have that the tax rate in the area is 7.1%.
3. Then to find the pre-tax subtotal, we can proceed as follows:
[tex]7.1\%=\frac{7.1}{100}=0.071[/tex]Therefore, we have:
[tex]x+0.071x=1253.07[/tex]4. Finally, we need to add the like terms as follows:
