The score of Jane is 27 and the score of Claire is 18.
A linear equation is an equation where highest degree of variables is 1.
Let the score of Jane's mark is x
Given, that score Jane is 9 more than the score of Claire.
So, the score of Claire= x-9
Given, the score of Jane is 60% of the sum of their scores.
the sum of their scores is = x+x-9= 2x-9
from the above it is clear that
the linear equation will be
x=60%(2x-9)
⇒x=0.6(2x-9)
⇒x= 1.2x -5.4
⇒1.2x-x= 5.4
⇒0.2x= 5.4
⇒x= 5.4/0.2
⇒x= 27
So the score of Jane is 27.
As score Jane is 9 more than the score of Claire.
the score of Claire is = x-9= 27-9=18
Therefore the score of Jane is 27 and the score of Claire is 18.

what is the slope of the line that passes through the points (-9,0) and (-17 , 0 )
Answer:
[tex]\mathrm{Slope=== > 0}[/tex]
Step-by-step explanation:
Hi student, let me help you out!
.............................................................................................................
First, let's recall the slope formula: [tex]\boxed{\mathrm{\cfrac{y2-y1}{x2-x1}}}}[/tex], where y2 and y1 are y-coordinates; x2 and x1 are x-coordinates.
Plugin the values: [tex]\mathrm{\cfrac{0-0}{-17-(-9)}}[/tex].
Upon simplifying, we obtain [tex]\mathrm{\cfrac{0}{-17+9}}[/tex].
Upon simplifying this further, we obtain [tex]\mathrm{\cfrac{0}{-9}}[/tex].
0 divided by anything results in 0.
✨ ∴, the slope of this particular line is 0, and this line looks something like this: [tex]\rule{200}{1}[/tex].
See, it's a horizontal line, with a rise of 0, meaning that it goes up 0 units.

Susan makes purple paint by mixing red and blue paint in the ratio 2:3
She has 12ml of red and 15ml of blue
What is the maximum amount of purple she can make?
A ratio shows us the number of times a number contains another number. The maximum amount of purple that Susan can make is 25 ml.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Susan makes purple paint by mixing red and blue paint in a ratio of 2:3. Now, if Susan wants to use the complete red paint then,
Purple paint she can make = 2/3 × 6/6 = 12 ml of red paint / 18 ml of blue paint
If Susan wants to use the complete blue paint then,
Purple paint she can make = 2/3 × 5/5 = 10 ml of red paint / 15 ml of blue paint
As per the first condition 18ml of blue paint is needed which is not possible, therefore, the second case is possible.
Thus, Susan needs to mix 10 ml of red paint and 15 ml of blue paint. Therefore, the amount of paint that Susan will make is,
Total Paint = 10ml + 15ml = 25ml
Hence, the maximum amount of purple that Susan can make is 25 ml.

Can you translate that into slope intercept form
Answer:
y = (5/3)x + 4
Step-by-step explanation:
The general equation for slope-intercept form is:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept. Since you have been given both of these values, you can plug them into the formula to find your answer.
slope (m) = 5/3
y-intercept (b) = 4
y = mx + b
y = (5/3)x + 4

What is the missing reason in the proof? (Reason 9)
Answer:
transitive property
Step-by-step explanation:
Generally proofs flow naturally from one step to the next. Consequently, each step usually follows from the previous step, and the Reason given justifies why that change is valid.
From statement 8, note that [tex]90^{o}=m\angle{ABD}[/tex]
For statement 9, the proof asserts that [tex]m\angle{ABC}=m\angle{ABD}[/tex]
What changed between line 8 and 9? The left side of the equation lost it's 90 degrees, and it became the measure of angle ABC.
So, what justifies changing the 90degrees into a measure of an angle (specifically, the measure of angle ABC)?
Recall from statement 3, that [tex]m\angle{ABC}=90^{o}[/tex].
The "substitution property" would be a valid reason for step 9, (but of the given options, that isn't one, so we must look for another valid reason).
Recall that the transitive property states:
[tex]\text{If }a=b\text{ and }b=c, \text{then }a=c[/tex]
There are three parts,
1. the first part needs a=b
2. the second part needs b=c
3. the third part produces a=c
Notice that in the second part, b=c, and then for the third part, on the left side, the "b" disappears, and the "a" sort of appears out of nowhere.
Statement 8 is like the second part, and statement 9 is like the third part.
Replacing "a" with [tex]m\angle{ABC}[/tex], replacing "b" with [tex]90^{o}[/tex], and replacing "c" with [tex]m\angle{ABD}[/tex], we can update the transitive property and see how it applies to our situation:
Original transitive property: [tex]\text{If }a=b\text{ and }b=c, \text{then }a=c[/tex]
Updated transitive property: [tex]\text{If }m\angle{ABC}=90^{o}\text{ and }90^{o}=m\angle{ABD}, \text{then }m\angle{ABC}=m\angle{ABD}[/tex]
In order to use the transitive property, we need the first part and the second part to be true, and then it will be a valid reason for the last part to be true. The first part was already proven back in statement 3, the second part was just proven in statement 8, so the conclusion (the third part) is valid and can be statement 9, because of the transitive property.

A:

The statements that would complete the proof where ∠2 ≅ ∠7 by the transitive property are:

What is the Transitive Property?The transitive property states that if x = y, and y = z, then x = z.
From the image given below, we have:
∠2 ≅ ∠3 because they are vertical angles which must be congruent.
∠3 ≅ ∠7 because corresponding angles are congruent.

Using it's concept, it is found that there is a 0.1541 = 15.41% probability that the first three balls are drawn out of the box alternated in colour.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Considering the situation described, the ways that alternate colored balls can be taken with the probabilities given as follows:
R(5/8) - W(3/9) - R(5/11).W(3/8) - R(5/10) - W(5/11).Hence the probability that the first three balls are drawn out of the box alternated in colour is given by:

The question is saying, how many three digit numbers can be made from the digits 3, 4, 6, and 7 but there can't be two of the same digit in them. For example 346 fits the requirements, but 776 doesn't, because it has two 7s.
Okay, on to the problem:
We can do one digit at a time.
First digit:
There are 4 digits that we can choose from. (3, 4, 6, and 7)
Second digit:
No matter which digit we chose for the first digit, there is only going to be 3 of them left, because we already chose one, and you can't repeat that same digit. So there are 3 options.
Third digit:
Using the same logic, there are only 2 options left.
We have 4 choices for the first digit, 3 choices for the second, and 2 for the third.
Hence, this is 4 * 3 * 2 = 24 three-digit numbers that can be made.

In MODE, (second line), fix the number of decimal places to be 2. Then the slope and the y-intercept values of the LinReg line will round to the nearest hundredth. Find the LinReg line of best fit for the National Health Expenditures data. Then predict national health expenditures for 2010. (Hint: You may have to expand the calculator window to include the year 2010 on your screen.)

What is the equation of a line passing through two points?Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by
[tex]\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)[/tex]
In MODE, (second line), fix the number of decimal places to be 2.
Then the slope and the y-intercept values of the Lin Reg line will round to the nearest hundredth.
(x₁, y₁) → (1997, 1093)
(x₂, y₂) → (2002, 1553)
Then we have
y – 1093 = [(1553 – 1093) / (2002 – 1997)] (x – 1997)
y – 1093 = [460 / 5] (x – 1997)
y – 1093 = 92 (x – 1997)
y = 92x – 182631
If x = 2010, then the value of y will be
y = 92 × 2010 – 182631
y = 184920 – 192631
y = 2289
