HELP PLEASE. THIS IS ABOUT FUNCTIONS ! EXPLANATION NEEDED PLEASE
Answer:
B
Step-by-step explanation:
Looking at the graph we can see that the function is increasing -4<x<-2 and 0<x2
The graph is increasing when it is going upwards, or has a slope greater than 0
We can see that happening in two places in the function, which are the intervals of the x coordinate in B
Answer:
B
Step-by-step explanation:
The function is increasing - 4 < x < - 2 and 0 < x < 2 and has a slope greater than 0, and it's happening at 2 places on the graph, so it's B
Hope this helps!

Answer:
b
Step-by-step explanation:
Can u guys PLEASE answer this question ASAP. A line passes through the point (2,4) and has a gradient 2. Find the y-coordinate of the point on the line when x=3
y=2
Step-by-step explanation:
Make an equation of straight line by using the formula :y= mx+c
put the x-value of point (2,4) which is 2 and the gradient,m which is 2 into the straight line equation:
y=2x +c
So you need to find the y-intercept to complete the equation, therefore:
when y=0,
0=2(2)+c
c=-4
next the question ask to find the y-coordinate when x =3, therefore you just need to replace x in the equation with 3:
y=2(3)-4
y=4

Meera bought two cows for $10000. If she sold one at the loss of 30% and other at the profit of 30% and she figures out that she sold them for the same price, Find the percentage of profit or loss in whole transaction!!!
Answer:
Step-by-step explanation:
30% off of 10000 is 3000
So the loss is 10000-3000=7000
30% gain on 10000 is 3000
so the gain is 10000+3000=13000
So in all there was no losses or gains. It still equals to 20000

Grace orders groceries worth $49.65. About how much should she spend for 12% home delivery charges?
Answer:
$5.96
Step-by-step explanation:
To find 12% of 49.65 you multiply 49.65*0.12 (decimal equivalent of 12%) = 5.958. Since it's money, you need to round to the nearest cent.
can you help me with this range problem?
Answer:
A) 3
Step-by-step explanation:
The range is the highest value - the lowest value from the data
The data given is 1,2,3,4
Highest value: 4
Lowest value: 1
So range = 4-1
= 3

Step-by-step explanation:
determine whether the system of linear equations has one solution, infinitely many solutions, or no solutions. Explain your reasoning. y=4x+6, 2y=8x+12
Answer:
Infinitely many solutions
Step-by-step explanation:
Since you already have y isolated in one equation, you can plug it in and use it in the other equation
2y = 8x + 12
2(4x + 6) = 8x + 12
8x + 12 = 8x + 12
Get the x's to one side
12 = 12
Meaning you have infinitely many solutions.
Try plugging in any x value you can think of and the left side will always equal the right side. so
x = 0 --> 8(0) + 12 = 8(0) + 12
12 =12
x = 1 --> 8(1) + 12 = 8(1) + 12
20 = 20
and so on.
I graphed it here for you and the 2 functions are on top of each other which means at every x value y = 4x + 6 is equal to 2y = 8x + 12

Solve:2/3 - 4x +7-2= -9.x +5/6
x = -3/2
x = -2/3
X=2/3
X=3/2
Answer:
2/3-4x+7-2=-9.x+5/6
2/3+7/1-2/1-5/6=-9.x+4x
12+126-36-15/18=-5x
87/18=-5x
29/6=-5x
29/6÷5=-5x÷5
29/6*1/5=-5x÷5
29/30=-x
-29/30=x

the first car costs $90 to rent, and because of its fuel consumption rate, there’s an additional cost of $0.50 per kilometers driven. How much is it for 500 kilometers
Answer:
It would be $340 (with rental cost)
Without the rental cost it would be $250
Step-by-step explanation:
You have to multiply $0.50 with 500 since you drove 500 kilometers. That gives you $250. When you add the $90 to rent, you get $340.
Equation: 90 + .05k
k= kilometers
Please help me with my question!!
Answer:
Step-by-step explanation:
Area of triangle = (1/2)bh
[tex]=\frac{1}{2}*25*21.65\\\\[/tex]
= 270.625 cm²
Area of 6 triangles = 6 * 270.625
= 1623.75 cm²
Trapezium:
a = 25 cm
b = 25 + 12.5 +12.5 = 50 cm
h = 21.65 cm
[tex]Area=\frac{(a+b)*h}{2}\\\\=\frac{(25+50)*21.65}{2}\\\\=\frac{75*21.65}{2}[/tex]
=811.875 cm²
Area of two trapezium = 2 *811.875
= 1623.75 cm²
Area of star = 1623.75 +1623.75
= 3247.50 cm²
Answer:
3247.50 cm sq

All three functions have a y-intercept.
All three functions have the same range values.
All three functions have the same domain values.
Answer:
Only f(x) has an x-intercept.All three functions have the same domain values.Step-by-step explanation:
We assume that the table represents the complete definitions of the functions of interest.
An x-intercept is a point where the y-value is 0. Only f(x) includes such a point: (-3, 0).
A y-intercept is a point where the x-value is 0. x=0 is not part of the domain of any of these functions, so there are no y-intercepts.
The maximum values of these functions are ...
f(x): 1g(x): -4h(x): 2so h(x) has the greatest maximum value.
The range of each function is the list of its table values. No two functions have the same range.
The domain of each function is the set of x-values for which it is defined. All of these functions have the same domain. That is, they are all defined for all of the x-values listed.
Of the descriptors offered, the two that apply are ...
Only f(x) has an x-intercept.All three functions have the same domain values.Answer:
A and E

3a² . 2a³ find the product
Answer:
[tex]6a^{5}[/tex].
Step-by-step explanation:
To multiply exponents, you will need to begin by multiplying the coefficients as normal. In this instance:
3 · 2 = 6.
When multiplying exponents, however, remember that you must ADD the exponents. Therefore:
3a² · 2a³ = [tex]6a^{5}[/tex]

Need help with question B asap pls will give brainiest and high points
Answer:
x = 16
Step-by-step explanation:
(b)
Since the triangles are similar then the ratio of corresponding sides are equal, that is
[tex]\frac{CB}{DE}[/tex] = [tex]\frac{AC}{AD}[/tex] , substitute values
[tex]\frac{x}{20}[/tex] = [tex]\frac{8}{10}[/tex] ( cross- multiply )
10x = 160 ( divide both sides by 10 )
x = 16
hurrryyyyy!!!! Need answer for work.
Answer:
x<7, The third option
Step-by-step explanation:
-1.1x+6.4>-1.3
We are trying to isolate x so we can move all the constant to one side.
-1.1x>-1.3-6.4
-1.1x>-7.7
Lastly, we need to divide both sides by -1.1.
-1.1x>-7.7/-1.1
Note that if you multiply or divide both sides of an inequality by a negative, then you need to flip the sign.
x<7
Hope this helps :)
Answer:
I believe it is the third option. It is really hard to explain. Lots of workout and I don't have enough time for it nut it is the third option...

What is the value of x?
The line is 7 units long. Add the two equations together and set equal to 7:
7x-1 + 2x-1 = 7
Combine like terms:
9x-2= 7
Add 2 to both sides:
9x= 9
Divide both sides by 9:
X= 1
Answer:
For 2x -1, X = 3 (2 x 3 = 6 - 1 = 5)
For 7x -1, X = 1/7 or 0.142857.

find the volume of this prism
Answer:
840cm^2
Step-by-step explanation:
Volume: Area of cross section x length
Area of cross section:(15 x 8 + 4x 5 )
length: 6
So volume:
(15 x 8 + 4x 5 ) x 6 = 120 + 20 X 6 = 140x6 = 840cm^2.
Hope this helps.
Good Luck
