Answer:
x = 1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form: x= 1/2
Decimal form: x = 0.5
Answer:
x= 1/2
Step-by-step explanation:
Let's solve your equation step-by-step.
(x−1)(x+7)=(x+1)(x−3)
Step 1: Simplify both sides of the equation.
x2+6x−7=x2−2x−3
Step 2: Subtract x^2 from both sides.
x2+6x−7−x2=x2−2x−3−x2
6x−7=−2x−3
Step 3: Add 2x to both sides.
6x−7+2x=−2x−3+2x
8x−7=−3
Step 4: Add 7 to both sides.
8x−7+7=−3+7
8x=4
Step 5: Divide both sides by 8.
8x/8 = 4/8
x = 1/2

Solve -2(5x – 3) = 41.
need help
Answer:
x = -7/2
Step-by-step explanation:
-2(5x - 3) = 41
Distribute the -2 inside the parenthesis.
-10x + 6 = 41
Subtract 6 from both sides.
-10x = 35
Divide both sides by -10.
x = 35/-10
Simplify the fraction.
x = -7/2.
Proof:
-2(5x - 3) = 41
Substitute variable.
-2(5(-7/2) - 3) = 41
Multiply 5 and -7/2.
-2(-35/2 - 3) = 41
Turn 3 into a fraction with denominator 2.
-2(-35/2 - 6/2) = 41
Subtract 6/2 from -35/2.
-2(-41/2) = 41
Multiply -2 and -41/2.
41 = 41.
write the equation of a line that is perpendicular to the line y=-3/4x+3 and passes through the point (3,7). Write your answer in BOTH point-slope form and slope-intercept form
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{3}{4}[/tex] x + 3 ← is in slope- intercept form
with slope m = - [tex]\frac{3}{4}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{3}{4} }[/tex] = [tex]\frac{4}{3}[/tex] , then
y = [tex]\frac{4}{3}[/tex] x + c ← is the partial equation
To find c substitute (3, 7 ) into the partial equation
7 = 4 + c ⇒ c = 7 - 4 = 3
y = [tex]\frac{4}{3}[/tex] x + 3 ← in slope- intercept form
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = [tex]\frac{4}{3}[/tex] and (a, b ) = (3, 7 ) , then
y - 7 = [tex]\frac{4}{3}[/tex] (x - 3) ← in point- slope form
Which expression is equivalent to 2(3x+4)(x−1)(x−3)?
Answer:
6x^3 - 16x^2 - 14x + 24
Step-by-step explanation:
(x - 1)(x - 3 ) = x^2 - 3x - x + 3
2 (3x + 4) = 6x + 8
(x^2 - 3x - x + 3) (6x + 8)
= 6x^3 + 8x^2 - 24x^2 - 32x + 18x + 24
= 6x^3 - 16x^2 - 14x + 24

Alyssa is painting 3 of the walls in her art studio blue Each of the walls is 8.3 feet tall and 7.5 feet wide.
Compare your estimate to the exact answer. Why is your answer reasonable?
Answer
5.0/5
1
Answer: below(=
Step-by-step explanation: Given that,
dimensions of wall = 8.3ft by 7.5ft
height of wall = 8.3
width of wall = 7.5
there are total 3 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
Height x Width
Formula to calculate area of four walls
3 (Height x Width)
= 3( 8.3ft x 7.5ft)
= 3 (62.25 ft²)
= 186.75 ft²
So area Alyssa will paint = 186.75 ft²

Sabrina has been walking dogs to earn money. This week she earned a total of $140
over the course of 7 hours. Assuming she charges clients a constant rate, which
graph below best represents this situation?
Answer:
y=20x; see below
Step-by-step explanation:
140/7=20
y=20x
If she charges clients a constant rate. Then the rate will be $20 per hour.
What is the rate?The rate is the ratio of the amount of something to the unit.
For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.
Sabrina has been strolling canines to bring in cash. This week she procured a sum of $140 throughout the span of 7 hours.
Assuming she charges clients a constant rate. Then the rate is calculated as,
Rate = $140 / 7
Rate = $20 per hour
If she charges clients a constant rate. Then the rate will be $20 per hour.

what is number 11. solve for x
Answer:
Step-by-step explanation:
okay so the equation is 3x - 12 = 78
add 12 on both sides
3x = 90
divide both sides by 3
x = 30
Answer:
The missing value (x) is 12.
Step-by-step explanation:
Given that there are two values already known, 78° and 78°, we can add them and get 156°.
Since a triangle has a total degree of 180°, we can do this:
180°-156° = 24°
So, now we have the missing angle and its equal to 24°.
what you now do is set 24°= 3x-12 to solve for x.
24°=3x-12
36=3x
/3
12=x
