Someone tell me the answer of an expression equivalent to 4-2(x+5). Please and Thank you.
Answer:
-2x - 6
Step-by-step explanation:
Multiplication must be done before addition or subtraction. Thus, we leave '4' as is and multiply out -2(x + 5), obtaining:
4 - 2x - 10, or -2x - 6
A line passes through the points (-100,-9.5•10^3) and (300,3.05•10^4). Find the value of y when x =200. Write answer in scientific notation.Please help asap with details and steps on how to solve.
Answer:
2.05x10^4
Step-by-step explanation:
The equation of the line is y=100x+500, which can be found through the given points.
So, if x=200, plug that into the equation of the line. y=100(200)+500
y=20000+500
y=20500
In scientific notation, that is 2.05x10^4

FIND THE AREA OF THE SHAPE AND THE PART THAT DOES NOT HAVE the empty part of the circle that says 6 on it
Find the area of the figure.
Answer:
132cm
Step-by-step explanation:
Split there firgue into shapes you know
there is a rectangle and a Trapezoid
A = bh
A = 7×4
A = 28cm
Trapezoid
A = 1/2h(b+b)
A = 1/2×8(19+7)
A = 1/2×8(26)
A = 1/2(208)
A = 104cm
Add them together
104 + 28 = 132
Can someone tell me how to approach this, I could care less about the answer I just want to know how to solve this without Desmos.
Thank you so much!
Answer:
the vertex is at (4, -14)
Step-by-step explanation:
Review "quadratic equations." These have three terms, and the highest power of x is x^2. We need to identify the coefficients of the x^2, x and x^0 terms to get info needed to identify the axis of symmetry.
Given f(x) = x^2 - 8x + 2, we see that these coefficients are 1, -8 and 2.
b
The formula for the axis of symmetry is x = - ------
2a
which here is x = -(-8)/[2*1], or x = 8/2 or x = 4: the axis of symmetry.
To find the y-coordinate of the vertex, evaluate the function at x = 4:
f(4) = 4^2 - 8(4) + 2 = 16 - 32 + 2, or f(4) = -14.
Thus, the vertex is at (4, -14). The graph is that of a parabola that opens up, and the parabola is symmetric about the vertical line x = 4.

Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.
The correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.
How to convert from decimal to fraction?For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.
For example:
[tex]0.99 = \dfrac{99}{10^2} = \dfrac{99}{100}[/tex]
(10 raised to power k = 1 followed by k zeroes)
How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
For this case, we can see from the image that:
Weight shown = 3 pounds + half more pound + half of 1/10 pound more approx. (as the weight hand is approx between 5 and 6 minor ticks after the big 3 pound mark). In each minor mark, one pound is divided in 10 parts, so each minor tick adds up 1/10 of a pound. Half of 1/10 shows that after 5, the hand is not exactly on 6 but sort of in between them, so approximately half.
Thus, weight shown ≈ 3 + 0.5 (half is written 0.5 too) + 1/10 of 0.5 pounds
= 3 + 0.5 + 0.5/10 = 3.5 + 0.05 = 3.55 pounds
Thus, the weight is approx 3.55 pounds.
Converting it to fraction, we get:
[tex]3.55 = \dfrac{355}{100} = \dfrac{5 \times 71}{5 \times 20} = \dfrac{71}{20}[/tex] pounds.
Thus, the correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.

In the earlier Lesson Activity, you found the sizes of mesoplankton and jellyfish. In this activity, you’ll determine the most appropriate units for measuring the sizes of mesoplankton and jellyfish.
Part B
You also found the size of a jellyfish to be 2 meters. Do you think that meters are the most appropriate unit to represent the size of a jellyfish? If not, what do you think would be the most appropriate unit? Write the size of the jellyfish in the most appropriate unit.
Answer:
We did not read the lesson so we dont kown
I can answer the seocnd question i think no because as meters may be to small for some jellyfish as they come in diffrence sizes so i think millimeter are the prefect size.

Answer:
4/6
Step-by-step explanation:
The probability of rolling a 6 is 1/6 as shown in the left section.
The probability of landing on tales is 1/2 as shown in the right section.
Becuase it is an or and not an and... you have to add them together.
1/6 + 1/2 = 1/6 + 3/6 = 4/6.
Therefore, the probability of rolling a 6 or landing on tails is 4/6.

The table shows the approximate number of minutes of physical exercise each student in Noah’s class gets per day. Identify any outliers in the data set and explain how they affect the data.
I need an explanation please.
Answer:
120 and 180 minutes have outliers
Step-by-step explanation:
An outlier is a point of data in a data set that is far out from the median in the data set. In this case, almost all of the data points are from 0 minutes of exercise to 60 minutes, except for two that are more than double that.
It could "skew" the data, as if you were to calculate the mean (average), it would be shifted slightly higher by these two outliers.

Find the value of x and find whether the angles or supplementary or complementary.
Answer:
Both angles add up to 90° so they are complementary angles, x = 55
Step-by-step explanation:
=> We know that both angles add to 90°, so the equation will be;
(x - 20) + (x) = 90
=> Using algebra if solved all the way down, "x" will be 55.
