What is the slope-intercept equation of this line?
Answer:
A. y=-3x+4
Step-by-step explanation:
Since the equation is in y=mx+b form, m represents the slope of a line. To solve for slope-intercept, use the equation m=(y2-x2)/(y1-x1).
[tex]m=\frac{-2-4}{2-0}[/tex]
[tex]m=\frac{-6}{2}[/tex]
[tex]m=-3[/tex]
Make sure to plug in one of the points into the equation to check if the numbers equal to one another or not.
Solve |4x +2|= 6
a.1 or -2
b.-1 or 2
c.1
s.2
Answer:
A
Step-by-step explanation:
When taking out the absolute value, it's 4x+2=6 and 4x+2=-6. At this point just solve for x and your answer(s) should be 1/-2
Answer:
x =1 x=-2
Step-by-step explanation:
|4x +2|= 6
There are two solutions a positive and a negative
4x+2 = 6 and 4x+2 = -6
Subtract 2 from each side
4x+2-2 = 6-2 4x+2-2 = -6-2
4x = 4 4x = -8
Divide by 4
4x/4 = 4/4 4x/4 =-8/4
x =1 x = -2
Which is greater 15/27 or 16/24
Answer:
16/24
Step-by-step explanation:
let’s use the GCF of both which is 3 for 15/27
15/27 divided by 3 is 5/9
for 16/24 the gcf is 8
16/24 / 8 is 2/3
now we have to multiply 2/3 times 3
2/3 times 3 6/3 which is 2
so 16/24 is greater.
In the number

Answer:
tenths place
Step-by-step explanation:
tens ones . tenths hundredths

The four is in the tenths place
Let's use the place value chart.
You can see that the digit 4 is in the tenths place.
So the value of the digit is 4 tenths.
If xy>0, then the points of P(x,y) lies...
Answer:
In Quadrant I or III
Step-by-step explanation:
We know if the sign was not showing closed inequality facing other way
xy < 0 would be in the 2nd or 4th quadrant.
If xy = 0 then either xy or both are on the x or y axis
But if xy>0 then they are in quadrant I or III
If xy>0, then the points of P(x,y) lies in Quadrant I and III
Quadrants on the Cartesian planeAccording to the given condition;
xy > 0This means that the product of x and y is a positive number.
Hence, either both x and y-coordinates are positive or are both negative
Hence, only points in the Quadrant I have positive x and y coordinates Or Quadrant III in which case all x and y values are negative.

The domain of the function f(x) = 3x3 is {2, 5}. What is the function’s range?
The range of the function f(x) = 3x3 when its domain is {2, 5} is
Answer:
[tex]Range = [24, 375][/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^3[/tex]
[tex]Domain = [2,5][/tex]
Required
Find the Range
The range is calculated by solving for f(2) and f(5). In other words, the range is calculated when x is 2 and x is 5
When x = 2;
f(2) is as follows;
[tex]f(2) = 3*2^3[/tex]
[tex]f(2) = 3 * 8[/tex]
[tex]f(2) = 24[/tex]
When x = 5;
f(5) is as follows;
[tex]f(5) = 3*5^3[/tex]
[tex]f(5) = 3 * 125[/tex]
[tex]f(5) = 375[/tex]
Hence, the range of the function is [24, 375]

Answer:
A: 5/23
Step-by-step explanation:
First, lets take the total amount of coins in the jar: 8 nickels, 10 dimes, 6 quarters, and 22 pennies- for a total of 46 coins.
The question is asking what the odds of pulling a dime are.
Since there is 46 coins in the jar, you can just do a fraction and set it up like this:
10
46
From there just simplify the fraction, 10 / 2 = 5, 46 / 2 = 23. The problem can't be simplified further, so the answer you originally had was correct. 5/23

A local car dealer has 150 cars on the lot. 30% of the cars are sedans. How many of the cars are NOT sedans?
Answer:
105 cars
Step-by-step explanation:
150cars=100%
and if 30% of the cars are sedans then the cars which are not sedans is
100%-30% =70%
if 150 cars=100%
? cars=70%
if less more devides
70%/100%×150cars
all zeros cancel which would be left with
7× 15
105 cars.
Answer:
The answer is 105
So that 30% of those cars are 45 Sedans of the 150 cars.
Now we need to find out how many cars are in that remaining 70%
In order to do this we need to subtract 45 from 150
So 150 minus 45 is 105
Finally, we know that that remaining 70% is 105 cars that aren't Sedans.
So 105 cars are not Sedans.
A truck can be rented from Company A for $120 a day plus $0.70 per mile. Company B charges $80 a day plus $0.90 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
200 miles
Explaination:
in order to fiind the point of interaction you must put the world problem into an liner equation.
y=mx+b
key:
miles : x
y= 0.70x + 120
&
y= 0.90x + 80
now you put them together
0.70x + 120 = 0.90x + 80
-0.70x. -0.70x
____________________ subtract slope from both sides
120 = 0.20x + 80. ( doesn't matter which one)
-80 - 80
____________________ subtract
40 = 0.20x
_________ Divide each # with the slope
0.20 0.20
200 = x

Describe the cross section.
Answer: D. Square
The cross section is shown as the shaded region. There are four sides to the shaded figure, so the cross section is a quadrilateral. This rules out choice C. We can also cross choice B off the list because cross sections of 3D figures are 2 dimensional.
Choice A is ruled out as well because we have both pairs of opposite sides that are parallel. The only thing left is choice D. This is true assuming we have a square prism. Any cube is a square prism that has its height equal to the width and length.

Hope this helps!
Steps:
Distribute the Negative Sign:
=-9n⁴+8+-1(9n⁴+2n³+5n²
=-9n⁴+8+−1(9n⁴)+−1(2n³)+−1(5n²)
=−9n⁴+8+−9n⁴+−2n³+−5n²
Combine Like Terms:
=−9n⁴+8+−9n⁴+−2n³+−5n²
=(−9n⁴+−9n⁴)+(−2n³+(−5n²)+(8)
=−18n⁴+−2n³+−5n²+8
Description:
The first steps is to distribute the Negative Sign, after you do it your equation will end like =−9n⁴+8+−9n⁴+−2n³+−5n². Second step is to Combine Like Terms/factors. When you do it your equation will end like=−18n⁴+−2n³+−5n²+8. And that will be the answer to simplify.
Answer: =−18n4−2n3−5n2+8

Conjecture: All student have school pride.
A. Jose goes to school every day.
B. Jessica studies and is attentive in class.
C. Joanna always wears her school colors and attend all school events she possibly can.
D. John does not wear his school colors and does not attend any school event
Please answer this
Answer:
Hey mate, here is your answer. Hope it helps you.
Step-by-step explanation:
D- John does not wear his school colors and does not attend any school event.
Description in mathematics, a conjecture is a conclusion or a proposition which is suspected to be true due to preliminary supporting evidence, but for which no proof or disproof has yet been found.
The counter-example for the given conjecture is "John does not wear his school colours and does not attend any school event". Therefore, option D is the correct answer.
The given conjecture is "All students have school pride."
We need to identify a counter-example for the given conjecture.
What is a conjecture?In mathematics, a conjecture is a conclusion or a proposition that is proffered on a tentative basis without proof. Some conjectures, such as the Riemann hypothesis or Fermat's Last Theorem, have shaped much of mathematical history as new areas of mathematics are developed in order to prove them.
Now, "All students have school pride" is not true, because not all students have school pride.
The counter-example for this conjecture is "John does not wear his school colours and does not attend any school event"
Therefore, option D is the correct answer.
