if 1/2x^2 - 1/4 x + 3 what is the value of x = 8 ?
Answer:
If x=8 then the equation is equal to 33
If 1/2(x)^2-1/4x=3=8 then x=-2.98 and x=3.35
Step-by-step explanation:
Given:
1/2x^2-1/4x+3
Two solutions possible:
If x=8 then 1/2(8)^2-1/4(8)+3=32-2=3=33
If 1/2(x)^2-1/4x+3=8 then .5x^2-.25x-5=0
factoring:
(.707x+2.11)(.707x-2.37)=0
.707x=-2.11 and .707x=2.37
x=-2.98 and x=3.35 rounded to 2 places

Solve for x:
17 - 4x = 33
Answer:
solve for X
17-4x=33
-4x=33-17
-4x=16
-4x/-4=16/-4
x=-4
Step-by-step explanation:
1. move the constant (17) to the right side
2. subtract the numbers on the right side (33-17)
3. Divide both sides of the equation by -4 (/4)
4. write the answer x= -4

Answer:
Option D
Step-by-step explanation:
Since, [tex]\frac{x-y}{x+y}=\frac{2}{7}[/tex]
7(x - y) = 2(x + y)
7x - 7y = 2x + 2y
7x - 2x = 2y + 7y
5x = 9y
[tex]\frac{x}{y}=\frac{9}{5}[/tex]
Since, ΔAED is similar to ΔACB,
Corresponding sides of these triangles will be proportional.
[tex]\frac{BC}{DE}=\frac{AC}{AE}[/tex]
[tex]\frac{x}{y}=\frac{8+AE}{AE}[/tex]
[tex]\frac{9}{5} =\frac{8+AE}{AE}[/tex]
9(AE) = 40 + 5AE
9(AE) - 5(AE) = 40
4(AE) = 40
AE = 10 cm
Therefore, Option D will be the answer.

Plane AXS intersects with which planes? More than 1 answer.
Answer:
Options A and Option B
Step-by-step explanation:
All four sides AX, IX, IS and AS of the base are common in the four side walls of the prism.
In other words, edge AX is common in planes AXU and AXS,
Edge XI is common in planes XIB and AXS,
Edge SI is common in planes EBS and AXS,
Edge AS is common in planes CEA and AXS.
Therefore, plane AXS is intersecting planes AXU and EBS.
Options A and Option B are the correct options.
GIVING BRAINLIEST SYSTEM OF EQUATIONS!!!!!!!!
Answer:
the grid supports the answer
Answer:
Step-by-step explanation:
The given equations are in standard form, first write them in slope-intercept form.
"p" is the variable in the x-axis
"g" is the variable in the y-axis
First equation
[tex]4p+2g=96\\2g=96-4p\\\frac{2g}{2} =\frac{96}{2} -\frac{4p}{2} \\g=-2p+48[/tex]
Second equation
[tex]3p+1g=60\\g=60-3p \\[/tex]
Next you have to determine two points for each equation, the easiest point to determine is the y-intercept, just replace the formula with p=0
First equation
for p=0
[tex]g=-2p+48\\g=-2.0+48\\g=48[/tex]
The first point is (0,48)
For p=10
[tex]g=-2.10+48\\g=-20+48\\g=28[/tex]
The second point is (10,28)
Plot the points and link them with a line.
Second equation
For p=0
[tex]g=-3p+60\\g=-3.0+60\\g=60\\[/tex]
The first point is (0,60)
For p=10
[tex]g=-3.10+60\\g=30\\[/tex]
The second point is (10,30)
Plot both points and link them to determine the line.

Mary drew a box and whisker plot for the following data: 23, 10, 12, 30, 26, 8, 25, 18.Find the following: First Quartile: Median: Third Quartile: Range:
Answer:
1st Qtrl: 11
Median: 20.5
3rd Qtrl: 25.5
Range: 22
Step-by-step explanation:
Median = average of 2 middle values (18 + 23) / 2
1st Qtrl = average of 10 and 12 (the lower half of data)
3rd Qtrl = average of 25 and 26 (the upper half of data)
Range = largest value - smallest value; 30 - 8 = 22

find two values for r which makes this statement true l r l=2
Answer:
r= -2 and 2
Step-by-step explanation:
The equation |r|=2 is an example of absolute value. So any number inside the absolute value symbols is positive. This is why -2 and 2 would be two values for this equation. So, |-2|=2 and |2|=2.

Step-by-step explanation:
Answer:
y= -5x+8
Step-by-step explanation:
So frstt you gotta know the form
y= mx+b
y= random Y-coordinate (not useful in this situation)
m= slope
x= random X coordinate (not useful in this situation)
b= y-intercept (the first point of the line that hits the y axis)
So first lets find the slope
sure we can use the slope formula between 2 points but I just did rise over run since this is an easy graph
Rise 5 and go Left 1 so the slope is -5/1 or -5 (negative due to the run going left instead of right plus the line is negative since its falling from left to right)
The y intercept is 8 becuase its the first point where the line crosses the Y axis
ANd thats it!
Plug it in
y= -5x+8
