The total area between the function f(x) = -6x and the x-axis over the interval [-4, 2] is -60 square units.
To find the total area between the function f(x) = -6x and the x-axis over the interval [-4, 2], we need to calculate the definite integral of the absolute value of the function over that interval.
Since the function f(x) = -6x is negative for the given interval, taking the absolute value will yield the positive area between the function and the x-axis.
The integral to find the total area is:
∫[-4, 2] |f(x)| dx
Substituting the function f(x) = -6x:
∫[-4, 2] |-6x| dx
Breaking the integral into two parts due to the change in sign at x = 0:
∫[-4, 0] (-(-6x)) dx + ∫[0, 2] (-6x) dx
Simplifying the integral:
∫[-4, 0] 6x dx + ∫[0, 2] (-6x) dx
Integrating each part:
[tex][3x^2] from -4 to 0 + [-3x^2] from 0 to 2[/tex]
Plugging in the limits:
[tex](3(0)^2 - 3(-4)^2) + (-3(2)^2 - (-3(0)^2))[/tex]
Simplifying further:
[tex](0 - 3(-4)^2) + (-3(2)^2 - 0)[/tex]
(0 - 3(16)) + (-3(4) - 0)
(0 - 48) + (-12 - 0)
-48 - 12
-60
Therefore, the total area between the function f(x) = -6x and the x-axis over the interval [-4, 2] is -60 square units. Note that the negative sign indicates that the area is below the x-axis.

gradient of line 6x+2y+9=0
Answer:
gradient = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c( m is the slope (gradient) and c the y- intercept )
Given
6x + 2y + 9 = 0 ( subtract 6x + 9 from both sides )
2y = - 6x - 9 ( divide the 3 terms by 2 )
y = - 3x - [tex]\frac{9}{2}[/tex] ← in slope- intercept form

−4p+9=−5
Plzzzzzzz help
Answer:
p = 3.5 or p = 7/2
Step-by-step explanation:
-4p+9= -5
or, -4p = - 14
or, p = -14/-4
or, p = 7/2 = 3.5
Answer:
p = 3.5
Step-by-step explanation:
What you would do to get p is subtract 5 from both sides of the equation to leave the number and p, THEN divide both sides by the numerator of -4.
-4p + 9 = -5
- 9 -9
__________
-4p = -14
__ __
-4 -4
Thus, p = 3.5

Answer:
FD = 8
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{FD}{BA}[/tex] = [tex]\frac{FE}{BC}[/tex] , substitute values
[tex]\frac{x+3}{2x+2}[/tex] = [tex]\frac{16}{24}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )
2(2x + 2) = 3(x + 3) ← distribute parenthesis on both sides
4x + 4 = 3x + 9 ( subtract 3x from both sides )
x + 4 = 9 ( subtract 4 from both sides )
x = 5
Thus
FD = x + 3 = 5 + 3 = 8
if the measure of angle 1 = 17x - 30 and the measure of angle 2 = 7x + 18, what is the value of x?
Answer:
do you know the answer
The value of x is 4.8.
Given that,
The measure of angle 1 = 17x - 30 and the measure of angle 2 = 7x + 18.Based on the above information, the calculation is as follows:
Angle 1 = ANgle 2
17x - 30 = 7x + 18
17x - 7x = 18 + 30
10x = 48
x = 4.8
Therefore we can conclude that the value of x is 4.8.

[tex]5*\frac{1}{2}[/tex]
Step-by-step explanation:
We have a picture and are being asked to identify the multiplication problem that represents it.
So we have 5 triangles, all of which are color-coded in red, but only half of them are filled. When multiplying, the number that is before the * sign is the amount there is, while the number that is after the * is the amount going to multiply the amount of items there are. So looking at the picture, we can see 5 triangles, therefore :
5 *
2 * 1/5 is scratched out as an answer. As is starts with 2.
As for the second number, we acknowledge that all triangles are half in red, therefore the number is 1/2.

Sorry this took a while; calculated a lot of things.
Step-by-step explanation:
A.
Combined:
2.67 times 23.76 = 63.4392
2.67 times - 21 and 5/6 = -58.295
63.4392 - 31.85 -58.295 = -26.7058
If you mean do both separate:
63.4392 - 31.85 = 31.5892
-58.295 - 31.85 = -90.145
B.
Combined:
11 and 3/4 times 23.76 = 279.18
11 and 3/4 times 21 and 5/6 = 256.541666667
279.18 + 256.541666667 + 56 and 3/8 = 592.096666667
If you mean do both separate:
279.18 + 56 and 3/8 = 335.555
256.541666667 + 56 and 3/8 = 312.916666667

A small plane flying from Los Angeles to San Diego averaged 175 mph with a tailwind. On the return trip with headwind the average speed was only 125 mph. Write and solve a system to reflect this relationship. Find the speed of the headwind/ tailwind AND the speed of the plane on a calm day.
Answer: System of equations:
p + w = 175
p - w = 125
p is the plane's speed, w is the wind speed
The wind speed is 25 mph. The plane's speed on a calm day is 150 mph.
Step-by-step explanation:
Solve by elimination: Add the equations. w "cancels" solve for p:
p + w = 175
p - w = 125
2p = 300 divide both sides by 2
p = 150 the plane's speed
Substitute 150 for p and solve for w
150 + w = 175 Subtract 150 from both sides.
w = 25 the wind speed
Jared made 12 3 fourhs cups of snack mix for a party his guests ate two thirds of the mix how much snack mix did his guests eat
Answer: Jared guests ate = 8 1/2 cups of the snack mix.
Step-by-step explanation:
Total snack mix made by Jared = 12 3/4 CUPS
Amount eaten by guests = 2/3 of Total snack mix
which means they ate = 2/ 3 x12 3/4
= 2/3 x 51/ 4
=17/2 = 8 1/2 cups of snack mix.
Jared guests ate 8 1/2 cups of the snack mix.

In ΔIJK, i = 74 inches, j = 23 inches and ∠K=20°. Find the area of ΔIJK, to the nearest square inch.
Answer:
291in^2
Step-by-step explanation:
Using the formula
Area of the triangle = 1/2absin theta
A = 1/2ijsin<K
Given
i = 74in
j = 23in
<K = 20 degrees
Area = 1/2 * 74*23sin20
Area = 37*23sin20
Area = 852sin20
Area = 291.059in^2
Hence the area of the triangle to nearest square inch is 291in^2
