Answer:
x = 4
Step-by-step explanation:
3x - 20 = -2x
Add 2x to both sides.
5x - 20 = 0
Add 20 to both sides.
5x = 20
Divide both sides by 5.
x = 4
Answer:
X = 4
Step-by-step explanation:
Find the slope of the line through the given points.* (-13, 10), (10, -13)
===========================================
Work Shown:
Let's apply the slope formula to get...
m = (y2 - y1)/(x2 - x1)
m = (-13 - 10)/(10 - (-13))
m = (-13 - 10)/(10 + 13)
m = -23/23
m = -1
The slope is -1
-----------
Extra info:
The slope is the rate of change. Specifically it's the change in y over the change in x. So that's why we divide the (y2-y1) over the (x2-x1). The (y2-y1) is the change in y; the (x2-x1) is the change in x.
You can think of it as
slope = rise/run
rise = y2-y1 = change in y
run = x2-x1 = change in x
Simplify:
6(2x2 – 5) = [?]
X=-3
Answer:
78
Step-by-step explanation:
Substitute x = - 3 into the expression
6(2(- 3)² - 5)
= 6(2(9) - 5)
= 6(18 - 5)
= 6(13)
= 78

Q1: Which transformation maps trapezoid 1 to trapezoid 2?
Q2: Which transformation could not map trapezoid 1 to trapezoid 8?
Q3: Which transformation maps trapezoid 2 to trapezoid 6?
options:
reflection
rotation
translation
Answer:
Rotation
Step-by-step explanation:
Rotation is the only one where you wouldnt be able to have the same points on the graph. Reflection and Translation can both place trapazoid 1 in the place of trapizoid 8.

Answer:
x = 13.3125
Step-by-step explanation:
Since it is a square, divide the area (225) by 4: 56.25
Now solve for x
56.25 - 3 = 53.25
53.25 / 4 = 13.3125
Please check if this is the method you need, and if I solved for the right thing!
On a scale drawing, the height of a tree is 3.75 inches. If the scale of the drawing is 1 in. : 50 ft, how tall is the tree?
HINT: Write and solve a proportion. You will compare 1 in to 50 feet and then determine how many feet 3.75 inches would be. REMEMBER: When writing your proportion, be sure that whichever (inches or feet) is on top and bottom of one ratio, it is in the same position (top or bottom) on other ratio.

Karen's garden measures 4.8 feet wide and 19.32 feet long. What is the area of her garden in square feet?
Answer:
92.736
Step-by-step explanation:
A = L* W
A = 4.8 * 19.32
A = 92.736
The length of a rectangular table is two times its width. If the perimeter of
the table is 2,000 ft, set up an equation to find the width (w) of the table.
1. 2000 = 2(2W + W)
2. 1000 = 2(3W+ W)
3. 2000 = 2(2wx W)
4. 2000 = 2(3wx w)
Answer:
1. 2000 = 2(2W + W)
Step-by-step explanation:
perimeter = 2(L + W)
L = 2W, so:
perimeter = 2(2W + W)
help me with this math question please I'm giving away brainliests
Answer:
Step-by-step explanation:
Given function is,
[tex]f(x)=\frac{2x^2+6x}{-4x^2+8x}[/tex]
[tex]=\frac{2x(x+3)}{-4x(x-2)}[/tex]
This function is not defined at "x(x - 2) = 0"
Therefore, for the values of x = 0 and 2, given function is not defined.
Vertical asymptote → x = 2 [Denominator = 0]
For Horizontal asymptote → [tex][\frac{2x^2}{-4x^2} =-\frac{1}{2}][/tex]
Therefore, horizontal asymptote → y = [tex]-\frac{1}{2}[/tex]
x-intercept,
For f(x) = 0,
Numerator of the function = 0
2x² + 6x = 0
2x(x + 3) = 0
x = -3
Therefore, x - intercept → (-3, 0)
For y-intercept,
x = 0
f(0) = 0
Therefore, graph has no y-intercept.
For holes on the graph,
Since, function is not defined at x = 0,
f(x) = [tex]\frac{(x+3)}{-2(x-2)}[/tex]
f(0) = [tex]\frac{(0+3)}{-2(0-2)}[/tex]
= [tex]\frac{3}{4}[/tex]
Therefore, hole on the graph → [tex](0, \frac{3}{4})[/tex]
