can someone explain to me how to solve this
h(x)=2x-6 find the value. -2[h(3)]
Answer:
-2[h(3)] = 0
Step-by-step explanation:
Step 1: Define
h(x) = 2x - 6
Step 2: Find h(3)
h(3) = 2(3) - 6
h(3) = 6 - 6
h(3) = 0
Step 3: Find -2[h(3)]
-2(0)
0

The total length of a vehicle is 205.83 inches. What is the length of the vehicle rounded to the nearest whole number?
A. 200 in B. 205 in C. 206 in D. 210 in
Answer:
If rounded up by the nearest whole number, it'd be 210, because it isn't using the decimal numbers, and the whole number would get the boot, meaning only 200 and 10 would remain. Please let me know if this helped.

Diane and Fran live in Warren, which is 108.7 miles away from the mall. If the average mileage of the car is 25.6 mpg, what is the consumption of gas for the round-trip?
Answer:
Consumption of gas = 8.5 gallon (Approx)
Step-by-step explanation:
Given:
Distance from mall = 108.7 miles
Average of car = 25.6 mpg
Find:
Consumption of gas
Computation:
Total distance covers = 2(108.7)
Total distance covers = 217.4 miles
Consumption of gas = 217.4 / 25.6
Consumption of gas = 8.4921
Consumption of gas = 8.5 gallon (Approx)
What are the two solutions of 2x2 = –x2 – 5x – 1?
Answer:
The answer is
[tex]x = \frac{ - 5 + \sqrt{13} }{6} \: \: \: \: or \: \: \: x = \frac{ - 5 - \sqrt{13} }{6} [/tex]Step-by-step explanation:
2x² = - x² - 5x - 1
Rearrange the terms and simplify
That's
2x² + x² + 5x + 1 = 0
3x² + 5x + 1 = 0
Using the quadratic formula solve the equation
That's
[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]From the question
a = 3 , b = 5 , c = 1
So we have
[tex]x = \frac{ - 5\pm \sqrt{ {5}^{2} - 4(3)(1) }}{2(3)} \\ = \frac{ - 5\pm \sqrt{25 - 12} }{6} \\ = \frac{ - 5\pm \sqrt{13} }{6} [/tex]We have the final answer as
[tex]x = \frac{ - 5 + \sqrt{13} }{6} \: \: \: \: or \: \: \: x = \frac{ - 5 - \sqrt{13} }{6} [/tex]Hope this helps you

If the measure of angle 1 is 110° and the measure of angle 3 is (2x+10)º, what is the value of x?
Answer:
x=50
Step-by-step explanation:
angle 1 and 3 are corresponding angles that menas they equal the same
so set it up like this 2x+10=110 solve for x
move over the 10, subtract 10 from 110 you get 100 and divide by 2
you get 50.

Please help me, I’m struggling!
Answer:
Multiply the numbers until you get the same denominator (Bottom number) for both fractions. I will do #1 to show you.
1/3 1/2
Both 3 and 2 go into 6, so I will use that.
When multiplying the bottom , you have to do the same to the top, so...
2/6 OR 3/6
3/6 is greater, so that is the answer.
Therefore, 1/2 is more
Another way you can do this is to draw a pizza, a section off parts of it according to the fractions.
Hope this helped.

The 7th term of an AP is 4 and its common difference is -4. What is the first term?
Answer: 28
Step-by-step explanation:
The 7th term of an AP is 4 and its common difference is -4. The 7th term of an arithmetic progression is written as:
a + 6d = 4
where,
a = first term
d = common difference= -4
a + 6d = 4
a + 6(-4) = 4
a - 24 = 4
a = 4 + 24
a = 28
The first term is 28.

Answer:
see explanation
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)
m = [tex]\frac{6+3}{2-8}[/tex] = [tex]\frac{9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]
------------------------------------------
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y = 5 - 2x , that is
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2

Consider that 1 inch = 2.54 centimeters. Which three statements are true for converting 18 feet to centimeters?
Answer:
There are 548.64 cm in 18 feet.
Step-by-step explanation:
We know that, 1 inch = 2.54 centimeters.
We need to convert 18 feet to centimeters
Also, 1 foot = 12 inch
Firstly we will convert 18 feet to inch.
18 feet = 12 × 18 inch
= 216 inch
Now to convert 18 feet to centimeters, multiply 216 inch by 2.54 cm as follows :
216 inch = 2.54×216 centimeters
= 548.64 cm
Hence, there are 548.64 cm in 18 feet.
