Find the slope of the line on the graph
Answer:
m = 1/2
Step-by-step explanation:
Use two points on the line given.
(0 , 2) & (-4 , 0)
You are solving for the slope. The slope formula:
m (slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (-4 , 0)
(x₂ , y₂) = (0 , 2)
Plug in the corresponding numbers to the corresponding variables:
m = (2 - 0)/(0 - (-4))
Simplify:
m = (2)/( 0 - (-4))
m = (2)/(0 + 4)
m = 2/4
Simplify the slope. Divide the common factor 2 from both the numerator and denominator:
m = (2/4)/(2/2) = 1/2
1/2 is your slope.

Atoms are made up of electrons, protons and neutrons. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. The oxygen atom has 8 electrons and 8 neutrons. How many protons must it have to have 0 charge?
Answer:
Protons and neutrons each count for one AMU, and the electron counts for zero AMU. So, if the atomic mass of oxygen is 16, that means we have a total of 16 protons and neutrons. 16 total protons and neutrons minus 8 protons leaves us with 8 neutrons.
donna spent a total of $80 at the grocery store of this amount she spent $64 on fruit what percentage of the total did she spend onf ruit
Answer:
Donna spent 80% on fruit.
Step-by-step explanation:
First, we know that she spent $64 on fruit. We also know that she spent a total of $80. Then, we take 64/80. This gives us 0.8. Move the decimal two to the right and you have the percentage, 80%.

Frank said that 8*10^4 is 320 do you agree or disagree
Answer:
I disagree with Frank
Answer:
Disagree
Step-by-step explanation:
Remember to follow the order of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
In this case, the first step should be to solve for [tex]10^{4}[/tex].
[tex]10^4 = 10 * 10 * 10 * 10 = 10,000[/tex]
Next, multiply by 8:
[tex]10,000 * 8 = 80,000[/tex]
80,000 is your answer, so I disagree.

find the zeros of the function: g(x)=(x -2)(3x +3)
Answer:
x = 2 and x = -1
Step-by-step explanation:
The zeroes of the function are found by setting g(x) equal to 0:
g(x) = (x - 2)(3x + 3) = 0
By the Zero Product Property, in order for this equation to be equal to 0, each of (x - 2) or (3x + 3) or both has to equal 0. So, set each equal:
x - 2 = 0
x = 2
3x + 3 = 0
3x = -3
x = -3/3 = -1
The zeroes are thus x = 2 and x = -1.

Latrell runs 5 miles during each track practice. How many track practices would it take for Latrell to run 25 miles?
Step-by-step explanation:
400 meters is standard lap distance for a race track. 2 x 50 meters is lap distance in International pools. A lap of 440 yards is 1/4 mile. So 4 laps/mile.
Answer:
It would take her 5 track practices to run 25 miles because she runs 5 miles each practice. We can divide 25 by 5 which gives us 5. So it would take 5 track practices for Latrell to run 25 miles. Hope this helps.

find b: since the triangle is right angle triangle apply the Pythagorean theorem
c²+b²=d²
b²=d²-c²
b²=16²-12²
b²=256-144
b²=112
b=√112 = 4√7the sum of the angle of the triangle=180
( in top Δ abd ) sin Ф=opp/hyp
sinФ=b/d=4√7/16= √7/4 radian
convert to degrees : √7/4 *180/π= 37.91 almost 38 degrees
which makes A= 38 degrees ( adjacent angles are equal when they have common side and do not overlap)find a=?? apply law of cosine
a²= d^2 + c^2 − 2dc cosA
a²=16² + 12²-2(16)(12)cos38
a =√(16² + 12²-2(16)(12)cos38)
a=9.87 rounded to the nearest hundredth(i hope it is right )

Determine whether the statement is true or false.
Answer:
False
Step-by-step explanation:
1/3^4=3^4
0.012346≠81
False
Answer:
True
Step-by-step explanation:
The negative power property of exponents says that:
[tex]x^{-n}=\frac{1}{x^n}[/tex]
And vice versa:
[tex]\frac{1}{x^{-n}}=x^n[/tex]
Therefore, since our exponent is negative, we can change it to positive if we put it in the numerator. In other words:
[tex]\frac{1}{3^{-4}}=3^4[/tex]
The statement is true.
