Solve: -4 (2x + 11) = -x + 12
Answer:
x=-8
Step-by-step explanation:
Multiply -4 by each number in the parenthesis ( distributive property )
Add x to -8x ( -7x )
Add 44 to 12 ( 56 )
Divide 56 and -7
You should get x=-8
Is the following number irrational?
-8.7
Answer:
No.
Step-by-step explanation:
Rational numbers are any of the following:
Integers (positive whole numbers, negative whole numbers, or zero).Fractions e.g. 3/4Terminating (with an end) or repeating decimals e.g. 0.2 or 0.333333... or 0.343434...Irrational numbers are thus defined as:
Non-terminating (unending), non-repeating decimal numbers. e.g. π, surds ( [tex]\sqrt{2}[/tex] ).This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.
in a stick of chalk carbon is 3 g what is the weight of the chalk stick
Answer:
Hence the weight of chalk stick is 25 g.
Explanation:
Let the weight of a stick be x gm.
12% of x=3
(12/100)*x=3
x=3*(100/12)=25 g
Answer:
weight of chalk = 25gStep-by-step explanation:
let chalk contains 10x calcium, 3x carbon, 12x oxygen.
percentage of carbon in the chalk:
= 3x x 100
10x + 3x + 12x
= 3x ( 100 )
25x
= 3 (4)
= 12%
Now, we know that carbon has 12% of chalk.
weight of carbon = 12% x weight of chalk. ------------- equation
plugin values into the equation:
3 = 12% (weight of chalk)
3 = 12 (weight of chalk)
100
12 (weight of chalk) = 3
100
weight of chalk = 3 (100)
12
weight of chalk = 25g

Daniel kicks a soccer ball and the trajectory is modeled by f(t) =− 16t^2+ 32t .
a. What would the value be of f(1)?
b. If it takes 2 seconds for the ball to hit the ground, what would a reasonable domain be for this function?
Answer:
f(1) = 16
Domain: 0 ≤ t ≤ 2
Step-by-step explanation:
Given
f(t) = -16t²+ 32t
Solving (a): f(1)
Substitute 1 for t in f(t)
f(t) =− 16t²+ 32t .
f(1) =− 16 * (1)²+ 32 * 1
f(1) = -16 * 1 + 32
f(1) = -16 + 32
f(1) = 16
Solving (b): The domain
The implication of the given parameter in (b) is that t ≤ 2.
Since t represents time, t can't be negative.
Hence, a reasonable domain is
0 ≤ t ≤ 2

Sometimes true
Never true
Always true
Answer:
always true
Step-by-step explanation:
Simplify, and if possible solve the equation to find out
remember, inverse operations
5x - 10 + 2x = 7 + 7x - 17
simplify both sides
7x - 10 = 7x - 10
this is an identity, no matter the value of x put in, the equation will be true,
hence the equation is always true

TRUE
FALSE
The statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.
To determine if the statement is true or false we need to know what radiactivity is
What is radioactivity?Radioactivity is the spontaneous disintegration of unstable atomic nuclei to form stable more energetic nuclei with the emission of radiation.
Radioactivity includes the following
disintegration of a larger atomic nuclei to a smaller more stable nucleiEmission of radiationSo, radioactive nuclei which are unstable emit radiation and become more stable.
So, the statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.

What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)
Answer:
y = -2/3x + 8/3aStep-by-step explanation:
Given points
(a, 2a) and (-5a, 6a)Slope-intercept form
y = mx + bSlope of the line is
m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3The y-intercept is:
2a = -2/3*a + bb = 2a + 2/3ab= 8/3aSo the line is:
y = -2/3x + 8/3aAnswer:
y = -2/3 - 8/3a
Step-by-step explanation:
Find the slope using [ y2-y1/x2-x1 ]
6a-2a/-5a-a
4a/-6a
-2/3
Find the y-intercept.
y = mx + b
y = -2/3x + b
2a = -2/3(a) + b
-8/3a = b
y = -2/3 - 8/3a
