Answer:
B) 0=(2x+3)(x-1)
Step-by-step explanation:
factor the equation f(x) = 2x² + x - 3
=> f(x) = (2x + 3)(x - 1)
Option B is correct.
What is zeros of a function?A zero of a function is a member of x of the domain of f such that f(x) vanishes at x, that is the function f attains the value of 0 at x.
According to the given question
we have a function
[tex]f(x)=2x^{2} +x-3[/tex]
[tex]f(x)=2x^{2} + 3x-2x-3[/tex]
[tex]f(x)=2x^{2} -2x+3x-3[/tex]
[tex]f(x)=2x(x-1)+3(x-1)[/tex]
[tex]f(x)=(2x+3)(x-1)[/tex]
for finding the zeros of f(x), substitute f(x)=0
[tex](2x+3)(x-1)=0\\[/tex]
⇒ x=[tex]\frac{-3}{2}[/tex] and x=1
Hence, option B is used for finding the zeros of the given function f(x).

Explain how solving -7y > 161 is different from solving 7y > -161.
help will give brinlest
Answer:
Dividing with negatives will result in a flip in the signs.
Step-by-step explanation:
In the first equation, -7y>161, if you solve it, you will need to divide both sides by -7.
[tex]-7y > 161\\ \\\\[/tex]
Since you are involving a negative, you will have to switch the signs. That means that if you have solved this, the answer would be:
y < -23Notice the change in signs.
---------------------------
Now in the second equation, the constant (161) is negative. So if you solve this,
[tex]7y > -161[/tex]
You will only need to divide both sides by 7, which is a positive number. That leaves the sign to stay the same, so the answer would be:
y > -23-----------------------If you look at the signs in both answers, they are flipped.Have a nice day!What is the range of the following relation?

Find the length of each arc. Use the exact answer
Answer:
D) 16π/3 ft
Step-by-step explanation:
The Question is calculated using Arc length formula
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
Hence, the arc length = Option D = 16π/3 ft

The length of a rectangle plus its width is 18 cm. The area is 80 sq cm. what are the length and width of the rectangle?
Answer:
80 units squared
Step-by-step explanation:
If two sides of a rectangle add up to 18cm and the area is 80 units squared then the length is 10cm, and the width is 8cm. If you add 10 and 8 together you get 18, and if you multiply those you get 80 units squared.

Find the midpoint of the segment with the following endpoints. (10, 7) and (5, 4)
Answer:
[tex]\frac{15}{2} , \frac{11}{2}[/tex]
Step-by-step explanation:-
To find the midpoint, the equation we use is:-
[tex]\frac{x1 +x2}{2} , \frac{y1 + y2}{2}[/tex]
x1 = 10
x2 = 5
y1 = 7
y2 = 4
Substituting the values in the equation, we get:-
[tex]\frac{10+5}{2} , \frac{7+4}{2}[/tex]
Coordinates of the midpoint---> [tex]\frac{15}{2} , \frac{11}{2}[/tex]

Answer:
C
Step-by-step explanation:
Both inequalities have y ≤ ( ), so will be bounded by solid lines, and shaded below that line (where y-values are lower). The first inequality has a boundary line with a steeply negative slope; the second has a shallow positive slope.
Since both are shaded below, the doubly-shaded area (AB) will be in the bottom quadrant, below the point of intersection of the lines. The graph attached below shows the correct shading.

Triangle theoroms, what is the value of x ?
Answer:
50.6
Step-by-step explanation:
MA=46.2-14=32.2
We have similar triangles.
That is, triangle MNP is similar to MAB.
This means, we have the following proportion to solve:
32.2/46.2=x/72.6
Multiply both sides by 72.6
32.2/46.2*72.6=x
50.6=x
