Subtract
8x - (5+4x)
Answer:
4x-5
Step-by-step explanation:
first make the equation easier 8x -1(5+4x)
then simplify with the parenthesis 8x -5-4x
then combine like terms 4x-5
there is you answer
Answer: The answer is 4x−5
Step-by-step explanation:
Distribute the Negative Sign:
=8x+−1(5+4x)
=8x+(−1)(5)+−1(4x)
=8x+−5+−4x
Combine Like Terms:
=8x+−5+−4x
=(8x+−4x)+(−5)
=4x+−5
write the equation of the line fully simplified slope-intercept form.

If an electric kettle uses
2 1/4 kilowatts of energy in 1.5 hours, how much energy will it use in 3.5 hours?
Answer:
The energy used in 3.5 hours = 5.25 kilowatts
Step-by-step explanation:
Energy used by electric kettle:
[tex]2\frac{1}{4}=\frac{9}{4}=2.25[/tex] kilowattsTime taken by electric kettle:
1.5 hoursElectric kettle's rate in kilowatts per hour can be calculated by dividing the spent energy i.e. 2.25 kilowatts by the time taken i.e. 1.5 hours.
Therefore,
Electric kettle's rate = 2.25 kilowatts / 1.5 hour
= 1.5 kilowatts per hour
Thus, the energy used in 3.5 hours = 1.5 × 3.5
= 5.25 kilowatts
Therefore, the energy used in 3.5 hours = 5.25 kilowatts

What is the value of FC?
A. 63
B. 4
C. 6
D. 9
Answer:
6
Step-by-step explanation:
Isosceles triangle is the triangle in which two sides of the triangle are congruent.The altitude from the top of an isosceles triangle bisects the base into two equal parts. The value of side FC is 12.
Given-
In triangle ADE side AE and the side DE are congruent.
The other side AD is the base of the triangle.
The triangle ADE is the isosceles triangle. For the isosceles triangle we know that the two sides are equal. In triangle ADE side AE and the side DE are congruent. the other side AD is the base of the triangle. The altitude form the top of an isosceles triangle bisects the base into two equal parts. thus the value of CD and AC is equal. Thus,
[tex]AC=CD[/tex]
In the question the value of CD is twelve units. Thus,
[tex]AC=12[/tex]
Hence the side AC is 12 units.
Now in triangle ABC side AB and the side BC are congruent.
The other side AC is the base of the triangle. The altitude form the top of an triangle ABC bisects the base AC into two equal. FC are 1/2 of the side AC. therefore,
[tex]FC=\dfrac{AC}{2}[/tex]
[tex]FC=\dfrac{12}{2}[/tex]
[tex]FC=6[/tex]
Hence, the value of side FC is 12 units.

Answer:
24
Step-by-step explanation:
If you see the big picture, you would realise ABC is actually a triangle so that means all the angles in it add up to 180°. The angle nearest point B is 90° since it is a right angle, the point nearest A is 66°, so you are able to find then angle nearest C, which is the angle of elevation.
Angle of elevation = 180° - 90° - 66°
= 24°

Solve the following system of intequalities graphing
Answer:
The attached figure shows the solutions to the system of inequalities
The solution of the system of the inequalities is all points lie on the area of the common shading (red and blue), not on the lines
Step-by-step explanation:
Let us find two points on each line to draw them
∵ y = [tex]\frac{1}{2}[/tex] x + 8 is the equation of the line
→ Put x = 0
∵ y = [tex]\frac{1}{2}[/tex] (0) + 8
∴ y = 8
∴ The point 1st point is (0, 8)
→ Put x = 2
∵ y = [tex]\frac{1}{2}[/tex] (2) + 8
∴ y = 1 + 8
∴ y = 9
∴ The point 2nd point is (2, 9)
∵ The sign of the inequality is >
∴ The line is a dashed line and the shading area is over the line
The red line and the red shading represent the solutions to the inequality
y > [tex]\frac{1}{2}[/tex] x + 8
∵ y = -x - 1 is the equation of the line
→ Put x = 0
∵ y = -1(0) - 1
∴ y = 0 - 1
∴ y = -1
∴ The point 1st point is (0, -1)
→ Put x = 2
∵ y = -1(2) - 1
∴ y = -2 - 1
∴ y = -3
∴ The point 2nd point is (2, -3)
∵ The sign of the inequality is <
∴ The line is a dashed line and the shading area is under the line
The blue line and the blue shading represent the solutions to the inequality y < -x - 1
The solution of the system of the inequalities is all points lie on the area of the common shading (red and blue), not on the lines
