Answer:
x= -7.27
Step-by-step explanation:
-81 = 5x + 3x + 3x - 1
combine all like terms
-81=11x-1
add 1 on both sides
-81=11x-1
+1 +1
-80=11x
divide by 11 on both sides to get x by itself
-80/11=11x/11
x=-7.27
Please help with this. With either question is okay :)
Answer:
slope: -3; y-intercept: (0,15)
Step-by-step explanation:
The slope is -3, simply move 3x to the right side for slope intercept form, the y-intercept is where x =0 so set x equalt to zero. 3(0)+y=15, y=15

Which equation represents a line which is perpendicular to the line 5x + 2y = 12?
Answer:
y = ²/₅ x - 3Step-by-step explanation:
Changing to slope-intercept form:
5x + 2y = 12 {subtract 5x from both sides}
2y = -5x + 12 {divide both sides by 2}
y = -⁵/₂ x + 6
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1
{Two lines are perpendicular if the product of theirs slopes is equal -1}
y =-⁵/₂ x + 1 ⇒ m₁ = -⁵/₂
-⁵/₂× m₂ = -1 ⇒ m₂ = ²/₅
So, any line perpendicular to 5x + 2y = 12 must have slope m =²/₅
#1: Solve the inequality below.
-3x + 5 < -19
Explanation: Just like any of your two-step equations,
in this inequality, start by isolating the x term which in this
case is -3x by subtracting 5 from both sides.
That leaves you with -3x < -24.
To get x by itself, divide both sides by -3 but watch out.
When you multiply or divide both sides of an inequality by a
negative number, you must switch the direction of the inequality sign.
So we have x < 8 and put your final answer in
set notation and it look like this → {x: x < 8}.

last week the tasha cola company had sales of 2,346.87 this week the company had sales of 8,867.14 Which is the estimate ofthe companys total sales for both weeks math problem
Answer:
11,214
Step-by-step explanation:
Given that :
Last week sales = 2,346.87
This week sales = 8,867.14
Total sales for bot weeks :
Last week sales + this week sales
2,346.87 + 8,867.14
= 11214.01
= 11,214

State the degree and end behavior of the following polynomial f(x)=4x^3+3x^5-x^2 - 2
Answer:
Degree
Five Degree
End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.
Step-by-step explanation:
[tex]y = 4 {x}^{3} + 3 {x}^{5} - {x}^{2} - 2[/tex]
A five-degree polynomial function. Rearrange the terms.
[tex]y = 3 {x}^{5} + 4 {x}^{3} - {x}^{2} - 2[/tex]
Because it is an odd-degree function, the graph increases from negative infinity and ends by increasing at positive infinity.
Graph / End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.
Please help me I will give you Brainly
Answer:
(- 1, 4 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 13 → (1)
2x - 2y = - 10 → (2)
Multiplying (2) by 2 and adding to (1) eliminates the term in y
4x - 4y = - 20 → (3)
Add (1) and (3) term by term to eliminate y, that is
7x + 0 = - 7
7x = - 7 ( divide both sides by 7 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
3(- 1) + 4y = 13
- 3 + 4y = 13 ( add 3 to both sides )
4y = 16 ( divide both sides by 4 )
y = 4
solution is (- 1, 4 )
While on vacation in Bloomington, Ashley went out for a dinner that cost $20. If sales tax in Bloomington is 10% and Ashley left a 15% tip on $20, what was the total cost of her meal?
Answer:
$25
Step-by-step explanation:
Given that:
Cost of Ashley's dinner in Bloomington = $20
Sales tax = 10%
Tip = 15% on $20
To find:
Total cost of the meal ?
Solution:
Let us find the sales tax first of all.
Sales tax is 10% of the total bill.
Therefore, sales tax = 10% of $20
[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]
Tip left is 15% of the total bill.
Therefore, tip = 15% of $20
[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]
Now, total cost of the meal = Food cost + Sales tax + tip
Total cost of the meal = $20 + $2 + $3 = $25

What does x stand for in math
Answer:
X is a value that is not known yet
Step-by-step explanation:
Normally x in an algebraic equation is what you are solving for...
Look at the system of equations:
2x + 6y = 10
5x + 15y =25
(HINT: solve for y=mx+b to graph!)
Which of these statements is correct?
A. The system has no solution
B. The system has an infinite number of solutions
C. The system has one solution at (-1,2)
D. The system has one solution at (5,0)
Answer:
B
Step-by-step explanation:
Both C and D solve the equations, so the system must have infinite solutions.

The slope is -1 and the y-intercept is -5. Write a linear equation in slope-intercept form.
Someone pls help me!
[tex]y = mx + b[/tex]
where m = slope and b = y-intercept.
We have both given slope and y-intercept. We can simply substitute the given slope and y-intercept in slope-intercept form.
SubstitutionSubstitute m = -1 and b = - 5 in the equation.
[tex]y = - 1x - 5 \\ y = - x - 5[/tex]
We don't usually write 1x or -1x instead we write -x or x.
Answer[tex]y = - x - 5[/tex]
