a = -1/2
Hope this helps :)
Answer:
a = -1/2
Step-by-step explanation:
-1/4a - 4 = 7/4a - 3
-a/2^2 - 4 = 7/ 2^2 a - 3
(-a) - ( 2^2) 4 / 2^2 = 7a/ 2^2 - 3
a = -1/2
I know this confusing but this how I got the answer.
I hope this helps
Evaluate the piecewise defined function at the indicated values.
{x² + 4x if x <equal/greater to -1
f(x) = { x if - 1<x< equal/greater to 1
{-1 x > 1
f(-2)=
f(-3/2)=
f(-1) =
f(0) = 0
f(25) =
Given:
Consider the piecewise function is
[tex]f(x)=\left \{\begin{matrix}x^2+4x,\text{ if } x\leq -1\\ x, \text{ if }-1<x\leq 1\\-1,\text{ if }x>1\end{Matrix}\right.[/tex]
To find:
The value of the function at indicated values.
Solution:
We know that, [tex]-2,-\dfrac{3}{2},-1[/tex] are less than or equal to -1. So, for these values the function is [tex]f(x)=x^2+4x[/tex].
For x=-2,
[tex]f(-2)=(-2)^2+4(-2)[/tex]
[tex]f(-2)=4-8[/tex]
[tex]f(-2)=-4[/tex]
Similarly,
For [tex]x=-\dfrac{3}{2}[/tex].
[tex]f(-\dfrac{3}{2})=(-\dfrac{3}{2})^2+4(-\dfrac{3}{2})=-\dfrac{15}{4}[/tex]
For [tex]x=-1[/tex].
[tex]f(-1)=(-1)^2+4(-1)=-3[/tex]
We know that, 0 is lies between -1 and 1. So, for this values the function is [tex]f(x)=x[/tex].
For x=0,
[tex]f(0)=0[/tex]
We know that, 25 is greater than 1. So, for this values the function is [tex]f(x)=-1[/tex].
For x=25,
[tex]f(25)=-1[/tex]
Therefore, the required values are, [tex]f(-2)=-4, f(-\dfrac{3}{2})=-\dfrac{15}{4},f(-1)=-3,f(0)=0,f(25)=-1[/tex].

What’s the domain and range?
Answer:
Domain(x): -2,2,3
Range(y): -1,4,5,6
(I put them in order numerically)
Step-by-step explanation:
The Domain is all the x values of the points given. It's always the first number of a point.
The range is the y values, it's always the second number given in a ordered pair!
Hope this helps! :)
Why does the range of this function include negative values? What is the significance of the point where the graph crosses the horizontal axis
Answer:
Because the graph does not include any negative values for the range, the range is only nonnegative real numbers. Cubic function f(x)- x^3.

Answer:
43.7
Step-by-step explanation:
7[tex]7^{2} +7^{2} =\sqrt{98} \\\sqrt{98}=9.899494937\\ That is the measurement for the dotted line. If we round it like they did in the example it would be 9.90. That is the measurement for all the sides of the square. \\We need the measurement for only 3 sides of the square and the two outer sides of the triangle (7ft)\\7ft + 7ft + 9.90 + 9.90 + 9.90 = 43.7\\\\Joshua added the 7's and they square rooted them for the Hypotenuse.\\Then the perimeter of all sides did not need any square roots.[/tex]

the two angles are supplementary if a=19x+3 and b= 21x +17 solve for x and find the measure of each angle
Answer:
x = 4
a = 79
b = 101
Step-by-step explanation:
Supplementary means equal to 180° after all angles are added together.
a=19x+3
b= 21x +17
(19x+3) + (21x +17) = 180
19x + 3 + 21x + 17 = 180
40x + 20 = 180
40x = 160
x = 4
a = 19(4)+3 = 79
b = 21(4) +17 = 101

minutes.
Can someone plz help me asap!
Answer:
The angle across the given measurements are the same. So there will be a 27 degrees across from the other 27 degrees. The straight line is 180 degrees, so do 180-27=153. The means the other 2 angles are 153 degrees. The other one is the same, but with different measurements. 180-35=145
Step-by-step explanation:
Let the angle adjacent to ∠27° be x .
[tex]∠x + 27 = 180° \: ( \: linear \: pair \: )[/tex]
[tex]x = 180 - 27 \\ ∠x = 153°[/tex]
Let the angle opposite to ∠27° be y .
[tex]∠y = ∠27° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle adjacent to ∠y ( 27°) be w .
[tex]w + ∠27° = 180° \: ( \: linear \: pair \: ) \\ w = 180 - 27 \\ ∠w = 153°[/tex]
Let the angle opposite to ∠35° be p .
[tex]∠p = ∠35° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle adjacent to ∠35° be a .
[tex]∠a + 35° =180 ° \: ( linear \: pair ) \\ a = 180 - 35 \\ ∠a = 145°[/tex]
Let the angle opposite to ∠35° be t .
[tex]∠t = 35° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle opposite to ∠145° be o .
[tex]∠o \: = 145° \: ( \: vertically \: opposite \: angles \: )[/tex]

2. The units of density for a rectan-
gular piece of wood are
a. grams per milliliter.
b. cubic centimeters.
c. kilograms per liter.
d. grams per cubic centimeter.
Answer:
d. grams per cubic centimeter
Step-by-step explanation:
The unit for density is g/cm^3 because the formula for density is mass divided by volume. The standard unit for mass is grams, and volume is cm^3. So by dividing the two numbers, the unit becomes both units divided.
