Mrs. K has 23 students in her class. Mr. Curran has 19 in his class.
How many more students does Mrs. K have than Mr. Curran?
Answer:
4 more students
Step-by-step explanation:
To find how many more students Mrs. K has, subtract 19 from 23:
23 - 19
= 4
So, Mrs. K has 4 more students than Mr. Curran

-8°C per minute. How many minutes will it take for the
solution's temperature to change from 0°C to -88°C?
hurry up
Answer:
11 minutes
Step-by-step explanation:
I may be missing something. This is too simple.
88 degree change at 8 degrees per minute = 11 minutes.
. Which inequality is shown in the graph below? O 1 ys-X+ 1 2 ys-x+1 8 O 1 y-X+1 2 yz x+1 4 2 -8-6420 -2 2 4 6 8 1 y> X+1 2 o *****1 -6 -8 O 1 y =X+ 1 2 y
Answer:
the answer is the last one 1 -6 -8 O 1 y =X 1 2 y
Step-by-step explanation:
The feasible region of the result is defined by the system of inequalities.
Correct response:
The system of inequalities shown in the graph is given by the option B.
B. y ≤ x + 1
y ≤ x² - 3·x
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
Methods used to find the system of inequalities

The possible graph obtained from a similar question has a straight line portion and a quadratic portion.
Points on the straight line are; (0, 1), (3, 4), and (5, 6)
Therefore;
Equation of the line is; y - 1 = 1 × x
Therefore;
y = x + 1
The shaded region is below the line which gives;
y ≤ x + 1
Points on the quadratic graph are; (0, 0), (4, 4), and (2, -2).
The general form of a quadratic equation is; y = a·x² + b·x + c
Therefore, we have;
0 = a × 0 + b × 0 + c
Which gives;
c = 0
4 = a × 4² + b × 4 = 16·a + 4·b
-2 = a × 2² + b × 2 = 4·a + 2·b
4 = 16·a + 4·b...(1)
-2 = 4·a + 2·b...(2)
Multiplying equation (2) by 2 and subtracting from equation (1) gives;
2 × -2 = 2 × (4·a + 2·b) = 8·a + 4·b
-4 = 8·a + 4·b
4 - (-4) = 16·a + 4·b - (8·a + 4·b) = 8·a
8 = 8·a
a = 1
-2 = 4 × 1 + 2·b
2·b = -2 - 4 = -6
Which gives;
y = 1·x² - 3·x = x² - 3·x
The line is a solid line and shaded region is the region under the graph which gives;
y ≤ x² - 3·x
Therefore;
The inequalities in the graph are given by option B.
B. y ≤ x + 1
y ≤ x² - 3·x

Clara lends half her collection of formal attires to her sister, Susan. Clara then buys four more attires now, how many attires did Clara had initially.
Answer:
let the numbet of formal attires with Clara be X
Clara lended susan 1/2 = X/2
Clara buys 4 = X/2 +4
Answer = X/2 + 4
( as the number of formal attires originakly with Clara is not specified)

Rotation about the origins, translation up 2
Reflection over the y-axis, translation down 7
Rotation about the origin, reflection over the x-axis
Reflection over the X-axis, dilation with a factor of 2
Answer:
Reflection over the X-axis, dilation with a factor of 2
Step-by-step explanation:
Dilation changes the size of the figure, therefore making it not congruent with the original figure.

can you write 3 1/3 as an improper fraction
Answer: 10/3 is the answer here you go
Answer:
10/3
Step-by-step explanation:
One trick I learned for writing improper fractions is multiply the whole number by the denominator to then add to the numerator. So in this case 3*3=9 and 9+1=10. So the improper fraction is 10/3
The function f(x) is a quadratic function and the zeros of f(x) are -2 and 6. Assume the leading coefficient of f(x) is 1. Write the equation of the quadratic polynomial in standard form.
Step-by-step explanation:
Since the zeroes of f(x) are -2 and 6,
(x + 2) and (x - 6) are factors of f(x).
=> f(x) = (x + 2)(x - 6) = x² - 4x - 12.
Answer:
The function f(x) is a quadratic function and the zeros of f(x) are -2 and 6. Assume the leading coefficient of f(x) is 1.
(x+2) and (x-6) are the factors of f(x)
[tex]f(x) = (x + 2)(x - 6) \\ = {x}^{2} - 6x + 2x - 12 \\ = \boxed{{x}^{2} - 4x - 12}[/tex]

what is the slope and y intercept for the equation y=1/2x-5
Answer:
1/2 (slope)
-5 (y-intercept)
Step-by-step explanation:
the slope-intercept formula is y=mx+b
m is the slope and y is the y-intercept. therefore the numbers that are substituting the position of the variables are the slope and intercept
y=1/2x-5
1/2 is substituting for m which is the variable for slope
-5 is substituting for b which is the variable for the y-intercept

Estimate the mean.
Give your answer rounded to 2 decimal places.
Answer:
The mean = 17.54
Step-by-step explanation:
Form a table as below;
Interval Frequency{f} Midpoint of frequency{x} fx
1-7 19 4 76
8-10 14 9 126
11-15 15 13 195
16-20 20 18 360
21-35 10 28 280
36-50 13 43 559
Sum 91 1596
The mean of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency
The mean= 1596 / 91
The mean = 17.54
a man bought a camera for rupees 460 and sold it at 5% profit find the selling price of the camera
Answer:
profit is 23 selling price is $483
Step-by-step explanation:
Cp of Camera=Rs.460
profit= 5%
so profit =5% of 460=(5*460)/100=Rs.23
then selling prices of camera= cp of camera + profit Rs=$460+23=483 hope this helps
Write the slope-intercept form of an equation of the line that passes through the point (5, -5) and is parallel to the graph of the equation 3x + y = -2.
Answer:
[tex]y=-3x+10[/tex]
Step-by-step explanation:
Parallel equations have same slope
Therefore slope of 3x + y = -2 is same as slope of other equation.
Slope of 3x + y = -2 is
m=-3
Now we have write equation having slope -3 and passing through point (5, -5)
[tex](y+5)=-3(x-5)[/tex]
[tex]y=-3x+10[/tex]
find the measure of the angle(s).
Answer:
x=10
Step-by-step explanation:
write an equation in slope- intercept form (y=mx+b) slope:0 y-intercept: 9
