Answer:
x=1/2
x=-o.5, x=-2
Step-by-step explanation:
To find x intercept/zero, substitue f(x)= 0-0 which gives you 0=2x+1. Then you solve for x to get x=-1/2 which is the answer. x=-o.5, x=-2 is the alterative form. Pls mark as brainlist if right.

Answer:
The probability of choosing a green shirt is 20%=1/5=.2
Step-by-step explanation:
find the total amount = 10
Find the total of question (probability of choosing green) = 2
set as a fraction:
Numerator = amount needed (2)
Denominator = all things/objects involved (10)
PS*
With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction
ex:
10/2=5=500% (this can't be the answer)
So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

what is -0.75 - 0.4 simplified
Answer:
= -0.75-0.4
= -1.15
Step By Step
The simplified result of -0.75 - 0.4 is -1.15.
To simplify the expression -0.75 - 0.4
Step 1: Start by subtracting the decimals without considering the signs: 0.75 - 0.4 = 0.35.
Step 2: Now, remember that the original expression had a negative sign in front of it, so the final answer needs to be negative. Since we already calculated a positive value (0.35), we'll make it negative by adding the negative sign: -0.35.
Step 3: Finally, we need to subtract the whole number parts. -0 (whole number part of -0.75) - 0 (whole number part of -0.35) = 0.
Putting it all together, we have -0 - 0.35 = -0.35.
But remember, the original expression had a negative sign, so the final result is -(-0.35), which simplifies to -0.35.
In mathematical terms, -0.75 - 0.4 = -0 - (0.75 - 0.4) = -0 - 0.35 = -0.35.
So, the simplified answer is -0.35, which can also be written as -1.15 (since -0.35 = -1.00 + 0.15).
In summary, when you subtract -0.4 from -0.75, you get -0.35 or -1.15, depending on how you choose to express it.

Question 13 of 15
A canoe travels 6 miles per hour downstream and 2 miles per hour upstream.
Let x represent the canoe's speed with no water current (still water) and y
represent the speed of the water current, in miles per hour. Then the situation
can be represented by this system of equations:
Choose the two correct options.
x + y = 6
x - y = 2
A. The speed of the canoe in still water is 4 miles per hour.
B. The speed of the canoe in still water is 2 miles per hour.
C. The speed of the water current is 4 miles per hour.
D. The speed of the water current is 2 miles per hour.
ANSWER : A AND D.
Step-by-step explanation:
the water current would be 2 mph and the canoe is 4 mph
See, 6miles downstream it would be 4mph of canoe + water boost ( 2 mph) = 6mph.
The canoe upstream would be 4mph - water resistance (2mph) = 2mph upstream.
The answers should be A and D.

Answer:
Midpoint: (-0.5, -1)
Step-by-step explanation:
Solution: M=(\(x m\),\(ym\))/2 or (\(x\)+\(x\)/2, \(y\)+\(y\)/2)
add the first \(x\) coordinate plus the second \(x\) coordinate
do the same for the two \(y\) coordinates
then divide them both by 2
should look something like this: (1+0 /2, -7+2 /2)
\(x\)= 1+0= 1 / 2 + 0.5 or one half 1/2
\(y\)= -7+2= -5 / 2 = -2.5 or four one half -2 1/2
BUT we are not done here, since we cant divide 1/2 no more because it will still give us the same answer (0.5) we move into the next number, -2 1/2, -2 x 1/2 = -1
So our answer is (-0.5, -1)

Which angle number represents an angle adjacent to
Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.
The properties of adjacent anglesAdjacent angles always share a common arm.They share a common vertex.They do not overlap.They have a non-common arm on both sides of the common arm.Two adjacent angles can be supplementary or complementary based on the sum of the measures of the individual angles.Here is a list of a few important notes related to the adjacent angles.When two angles are adjacent, then their sum is the angle formed by two non-common arms and one common arm.If a ray stands on a straight line, then the sum of adjacent angles formed is 180°.If the sum of two adjacent angles is 180° then they are called a linear pair of angles. All linear pairs are supplementary because supplementary angles sum up to 180°. However, all supplementary angles need not be linear pairs. To form a linear pair the lines need to intersect each other and must form adjacent angles.If the sum of two adjacent angles is 180° then the non-common arms form a line.
So the Adjacent Angle to ∠LSP is ∠PSM.
∠PSM number is 5

In triangle XYZ, m∠Z = (5m − 16)° and the exterior angle to ∠Z measures (3m + 12)°. Determine the value of m.
m = 3
m = 10.8
m = 18
m = 23
Answer:
Step-by-step explanation:
Each Exterior angle = 180° - Interior angle.
(3m + 12)° = 180° - (5m − 16)°
Then solve algebraically:
\(3m+12=180-5m-16\)
\(3m+12=-5m+164\)
\(8m+12=164\)
\(8m=152\)
m = 19
The value of m will be 23.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In triangle XYZ,
⇒ m ∠Z = (5m − 16)°
And, the exterior angle to ∠Z measures (3m + 12)°.
Now,
Since, The sum of angle and its exterior angle in a triangle will be 180°
Hence, We can formulate;
(5m − 16)° + (3m + 12)° = 180
Solve for m as;
5m - 16 + 3m + 12 = 180
8m - 4 = 180
8m = 180 + 4
8m = 184
m = 23
Thus, The value of m will be 23.

What is an interquartile range?The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located. To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.
