Let's solve your equation step-by-step.
7x+3+x+55=14x−5+x
Step 1: Simplify both sides of the equation.
7x+3+x+55=14x−5+x
7x+3+x+55=14x+−5+x
(7x+x)+(3+55)=(14x+x)+(−5)(Combine Like Terms)
8x+58=15x+−5
8x+58=15x−5
Step 2: Subtract 15x from both sides.
8x+58−15x=15x−5−15x
−7x+58=−5
Step 3: Subtract 58 from both sides.
−7x+58−58=−5−58
−7x=−63
Step 4: Divide both sides by -7.
−7x
−7
=
−63
−7
x=9
7(9) + 3
63 +3

Step-by-step explanation:
a force of 10 newtons acts in a direction 75 above horizontal moving an object 15 meters from (0,0) to (15,0). What is the work done by the force?
a. 2.59 joules
b. 3.88 joules
c. 38.82 joules
d. 150.00 joules
Answer:
150 JoulesStep-by-step explanation:
Step one:
Given data
Force F= 10N
the distance is described by the coordinate = (0,0) to (15,0)
hence the distance = 15m in the x-direction.
Step two:
Required is the work done
we know that work done is expressed as
Wd= Force* Distance
Wd= 10*15
Wd= 150 Joules
Answer:
38.82

What do the differences between the points (as shown on the graph) represent? On a coordinate plane, point B is at (2, 7) and point D is at (4, 14). StartFraction 7 over 2 EndFraction is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph. StartFraction 2 over 7 EndFraction is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph. StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1. StartFraction 2 over 7 EndFraction can be used to find the unit rate if one divides 2 by 7 and compares the result to 1.
Answer:
StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
B(2, 7) and D(4, 14)
substitute the values
The unit rate is
therefore
StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1

What is the roots of f(x)=-x^2-6x-14
Answer:
[tex]x=-3\pm i \sqrt{5}[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Standard Form: ax² + bx + c = 0Quadratic Formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]Algebra II
Imaginary roots: √-1 = iStep-by-step explanation:
Step 1: Define function
f(x) = -x² - 6x - 14
Step 2: Set up
Set equation equal to 0: -x² - 6x - 14 = 0Factor out -1: -(x² + 6x + 14) = 0Divide both sides by -1: x² + 6x + 14 = 0Step 3: Define variables
a = 1
b = 6
c = 14
Step 4: Find roots
Substitute: [tex]x=\frac{-6\pm\sqrt{6^2-4(1)(14)} }{2(1)}[/tex]Exponents: [tex]x=\frac{-6\pm\sqrt{36-4(1)(14)} }{2(1)}[/tex]Multiply: [tex]x=\frac{-6\pm\sqrt{36-56} }{2}[/tex]Subtract: [tex]x=\frac{-6\pm\sqrt{-20} }{2}[/tex]Factor: [tex]x=\frac{-6\pm\sqrt{-1} \sqrt{20} }{2}[/tex]Simplify: [tex]x=\frac{-6\pm2i \sqrt{5} }{2}[/tex]Factor: [tex]x=\frac{2(-3\pm i \sqrt{5} )}{2}[/tex]Divide: [tex]x=-3\pm i \sqrt{5}[/tex]Graph the line.
y=3x-7
Step-by-step explanation:
so the -7 means that the line will cross the y-axis at the point (0,-7). from there, we knows the slope is 3. slope is rise over run, so 3 over 1. we go up 3 and over 1

John read the first 114 pages of a novel, which was 3 pages less than 1/3 of the novel. Write an equation to determine the total number of pages (p) in the novel. Find the total number of pages in the novel.
Answer:
The novel has 117 pages
Step-by-step explanation:
Let p be the pages in the novel
p − 3 = 114
p = 117
Answer:
351
Step-by-step explanation:
114 = p/3 - 3
p/3 = 117
p = 351 page

What is the volume of material he must purchase?
2 ft3
4 ft3
6 ft3
8 ft3
Answer:
In this problem, we use the formula for volume which is:
volume=(length*width*height)/3
Since the base of the triangle is a square, we simply know that the length and width is equal.
L = W = 2 ft
H = 6 ft
Solution:
V = (2*2*6)/3V = 8 ft^3
The correct answer is 8 ft^3

The length of a rectangle is four times its width.
If the area of the rectangle is 144 ft, find its perimeter.
Answer:
y = mx + c
since m = 0
c = 9
Answer: 60
suppose: the width of a rectangle is x (x > 0)
⇒ The length of a rectangle is 4x
because the area of the rectangle is 144 ft
=> 4x.x = 144
⇔ x² = 144/4 = 36
⇒ x = 6
with x = 6 ⇒ The length of a rectangle is 4.6 = 24
the perimeter of the rectangle is (6 + 24).2 = 60

How would you do this and how would you graph it on a number line
Answer:
k=-5,5
Step-by-step explanation:
first you calculate (by switching the -6 to the other side)
|k|<-1+6
second you add the -1+6 and get |k|<5
the other part will be that the |k| will turn to - negative.
now you will have -k<5 then not you have to take the negative of -k to only have, (k<-5), k equalling to -5.
But remeber you always flip the < to > when you have the greater-to-equal sign or less-to-equal sign.
