what is the coefficient of -2x+8=10
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+8=10
Step 1: Subtract 8 from both sides.
−2x+8−8=10−8
−2x=2
Step 2: Divide both sides by -2.
−2x−2=2−2
x=−1
Answer:
Answer:
-2
Step-by-step explanation:
The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.

which graph represents the system of equation? Y greater than negative 1/3 x + 4 + 2x - 3y less than equal to 12
Answer:7x/3 - 3y +4 hope this helps!
Step-by-step explanation:
Solve 4x + 8y = 16 for x.
O A. x=-8y + 4
O B. x= -2y+ 16
O C. x= -2y+ 4
D. X = 8y + 16
4x + 8y = 16
4x = 16 - 8y
4x = 4 (4 - 2y)
x = 4( 4 - 2y)/4
X = 4 - 2y
X = -2y + 4

Zoe paid 18.60 in sales tax and tips for dinner. The sales tax is 11% and she tipped 20%. What was the price of Zoe’s dinner before sales tax and tip?
Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
Sales tax = 11% * original price = 0.11 * x= 0.11xTips for dinner = 20% * original price = 0.20 * x = 0.2x0.11x + 0.2x = 18.600.31x = 18.60x = 60$60 was the price of Zoe's dinner, before sales tax and tip.Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
1. Sales tax = 11% times original price = 0.11 times x= 0.11x
2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x
3. 0.11x + 0.2x = 18.60
4. 0.31x = 18.60
5. x = 60
6. $60 was the price of Zoe's dinner, before everything else

Please, i need help on how to solve problems like these. I dont understand and i wasnt in class when they taught it to us. PLzzzz.Will make it the brainiest if its corrected and explaining how to solve problems like these.
Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20

Answer:
a) 13%
b) 65.9%
Step-by-step explanation:
a) You can use n=1 to find the percentage remaining at the end of 1 hour:
P = 100(0.87^1) = 87
This is 13% less than 100%, so the decay rate per hour is 13%.
__
b) Fill in n=3 and evaluate the expression.
P = 100(0.87^3) = 65.8503
After 3 hours, about 65.9% of the caffeine remains.
Liz lives 3 miles from the library.
Brendan lives 3 times as far as Liz.
Andy lives 3 times as far as Brendan.
Eddie lives 3 times as far as Andy.Which exponential expression represents how far Eddie lives from the library?
A.3 the the 5th power miles
B.4 to the 3rd power miles
C.3 to the 4th power miles
D.3 to the 3rd power miles
Answer:
C.
Step-by-step explanation:
3 times 3 =9 and is 3 by the 2nd power. Then that times three is 27 which is 3 to the third power. Now it’s time to find out where Eddie is compared to the library. Then that times 3 is 3 to the fourth power. So that’s how far Eddie is. He is 81 miles away.
Solve for y y + 7 = 9
Answer:
y = 2
Step-by-step explanation:
Given
y + 7 = 9 ( subtract 7 from both sides )
y = 2
Simplifying
y + 7 = 9
Reorder the terms:
7 + y = 9
Solving
7 + y = 9
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + y = 9 + -7
Combine like terms: 7 + -7 = 0
0 + y = 9 + -7
y = 9 + -7
Combine like terms: 9 + -7 = 2
y = 2
Simplifying
y = 2

SOMEONE PLEASE ANSWER
the equation is 7x-3 over 9 > 8-2x
Answer:
solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]
First we will solve the inequality to find value of x
Solving:
[tex]\frac{7x-3}{9}\geq 8-2x[/tex]
Step 1: Multiply both sides by 9
[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]
Step 2: Adding 3 on both sides
[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]
Step 3: Add 18x on both sides
[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]
Step 4: Divide both sides by 25
[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]
So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
