Given the function f(x)=2x-7. What is x when f(x)=17?
Answer:
x = 12
Step-by-step explanation:
Step 1: Define
f(x) = 2x - 7
f(x) = 17
Step 2: Substitute
17 = 2x - 7
Step 3: Solve for x
Add 7 on both sides: 24 = 2x
Divide both sides by 2: 12 = x
Step 4: Check
f(12) = 2(12) - 7
f(12) = 24 - 7
f(12) = 17
Answer:
f(17)=2(17)-7
=34-7

Step-by-step explanation:
BD = DC because angles ADC and ADB are right angles.
Thus, [tex]4x-5=2x+7[/tex]
Add 5 to both sides:
[tex]4x-5+5=2x+7+5[/tex]
[tex]4x=2x+12[/tex]
Subtract 2x from both sides:
[tex]4x-2x=2x+12-2x[/tex]
[tex]2x=12[/tex]
Divide both sides by 2:
[tex]\frac{2x}{2}=\frac{12}{2}[/tex]
[tex]x=6[/tex]
DC [tex]=4x-5[/tex]
[tex]=4(6)-5[/tex]
[tex]=24-5[/tex]

0.5x -2 = 1.5x + 0.15
Answer: x=−2.15
Step-by-step explanation : Alright Let's solve your equation step-by-step.
0.5x−2=1.5x+0.15
Step 1: Subtract 1.5x from both sides.
0.5x−2−1.5x=1.5x+0.15−1.5x
−x−2=0.15
Step 2: Add 2 to both sides.
−x−2+2=0.15+2
−x=2.15
Step 3: Divide both sides by -1.
−x

"2. A $480,000 note payable requires 9.1% annual interest, or $3,640, to be paid at the 20th day of each month. The interest was last paid on April 20 and the next payment is due on May 20. As of April 30, $1,213 of interest expense has accrued.
3. Total weekly salaries expense for all employees is $9,000. This amount is paid at the end of the day on Friday of each five-day workweek. April 30 falls on a Tuesday, which means that the employees had worked two days since the last payday. The next payday is May 3. The above three separate situations require adjusting journal entries to prepare financial statements as of April 30. For each situation, present both the April 30 adjusting entry and the subsequent entry during May to record the payment of the accrued expenses. (Use 360 days a year. Do not round intermediate calculations.)"

The boiling point of three components A, B and C of petroleum are 120○C, 70○C, 250○C respectively. If a mixture of these three is fractionally distilled, which of these will be obtained at the bottom of the distillation column?
Answer:
Mustaali Chill Bro
Component C, with a boiling point of 250°C, will be obtained at the bottom of the distillation column.
The component with the highest boiling point will be obtained at the bottom of the distillation column.
In this case, component C has the highest boiling point at 250°C, followed by component A at 120°C, and component B at 70°C. Therefore, during fractional distillation, component C will be obtained at the bottom of the distillation column.

During a heavy rainstorm, a city in Florida received
12 1/4 inches of rain in 25 1/2 hours. What is the approximate rainfall rate in inches per hour?
Answer: 0.48 in
Step-by-step explanation:
The problem asks for unit rate. To solve, let's convert the fractions to decimals.
[tex]12\frac{1}{4} =\frac{49}{4} =12.25[/tex]
[tex]25\frac{1}{2}=\frac{51}{2}=25.5[/tex]
Now that they are in decimals, we can set up a proportion.
[tex]\frac{12.25 in}{25.5 hrs} =\frac{x}{1 hr}[/tex] [cross multiply]
[tex]12.25=25.5x[/tex] [divide both sides by 25.5]
[tex]x=0.48[/tex]
Now, we know that there was approximately 0.48 in of rainfall per hour.
Complete the statement. The drawing is not to scale. If mangle upper D upper G upper F = 84°, then mangle upper D upper E upper F = ___. Two adjacent triangles are shown.

Solve the linear equation: 3(4 + 2b) - b = 27 A b = 15 B b = 5 C b = 3 D b = -3
Answer:
Multiply the numbers in parentheses by 3.
Which gives you 12 + 6b - b =27
Combine like terms
12 + 5b = 27
Then subtract 12 from both sides
Which leaves you with
5b = 15
Divide both side by 5

18= 5m + 3 .. what would b m?
Answer:
m=3
Step-by-step explanation:
Move all terms that don't contain m to the right side and solve.
Answer:
m=3
Step-by-step explanation:
Simplifying
18 = 5m + 3
Reorder the terms:
18 = 3 + 5m
Solving
18 = 3 + 5m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-5m' to each side of the equation.
18 + -5m = 3 + 5m + -5m
Combine like terms: 5m + -5m = 0
18 + -5m = 3 + 0
18 + -5m = 3
Add '-18' to each side of the equation.
18 + -18 + -5m = 3 + -18
Combine like terms: 18 + -18 = 0
0 + -5m = 3 + -18
-5m = 3 + -18
Combine like terms: 3 + -18 = -15
-5m = -15
Divide each side by '-5'.
m = 3
Simplifying
m = 3

Step-by-step explanation:
find the value of x
Answer:
x = 68°
Step-by-step explanation:
∠ DCB = ∠ EDC = 27° ( alternate angles )
Thus ∠ ECB = 23° + 27° = 50°
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (62 + 50)° = 180° - 112° = 68°
Answer:
68°
Step-by-step explanation:
DE ║ BC
So, ∠DBC = ∠ADE = 62° (∵ Corresponding Angles are equal )
In triangle DEC ,
∠EDC+ ∠ECD = ∠AED (∵ Exterior Angle Sum Property of a triangle )
⇒ ∠AED = 23° + 27° = 50°
Now in triangle AED ,
∠EAD + ∠ADE + ∠AED = 180°
⇒ x° + 62° + 50° = 180°
⇒x° = 180° - 112° = 68°
