solve for x 10x+1=12x-5
Answer:
x=3
Step-by-step explanation:
1) 10x+1-1 = 12x-5-1, this becomes a new equation
Equation: 10x = 12x-6
2) 10x-12x = 12x-12x-6, this become a new equation
Equation: -2x = -6
3) Divide both sides by -2: -2x/2 = -6/2
4) Once you simplify, you will get x=3

Angela is shopping for pet supplies and needs to buy a kennel and several toys. At Paws R Us, she would pay $50.75 for the kennel and $3.75 for each pet toy. At Truth or Tail, she would pay $43.25 for the kennel and $5 for each pet toy. Write an inequality to represent t, the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option.
Answer: t>6
Step-by-step explanation:
Amount to pay = Cost of kennel + (Cost per toy )x (Number of toys)
Let t = the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option.
Given, At Paws R Us, she would pay $50.75 for the kennel and $3.75 for each pet toy.
Amount to pay = $(50.75 + 3.75t)
At Truth or Tail, she would pay $43.25 for the kennel and $5 for each pet toy.
Amount to pay = $(43.25 + 5t)
According to the question , we have
50.75 + 3.75t < 43.25 + 5t
Subtract 3.75t from both sides
50.75+ 3.75t -3.75t < 43.25 + 5t -3.75t
⇒ 50.75< 43.25 +1.25 t
Subtract 43.25 from both sides, we get
50.75 - 43.25 < 1.25 t
⇒ 7.5< 1.25 t
Divide both sides by 1.25 we get
⇒ 6<t
Hence, the required inequality to represent t, the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option:

How are subtracting and adding intigers related
Answer:
Adding integers means adding integers with the same signs, while subtracting integers means adding the integers of opposite signs.
Step-by-step explanation:
Answer:
addition is subtraction of the opposite, and vice versa
Step-by-step explanation:
Subtracting an integer is the same as adding its opposite. Likewise, adding an integer is the same as subtracting its opposite.

Which statement is true regarding the graphed functions?
Options:
• f(4) = g(4)
• f(4) = g(-2)
•f(2) = g(-2)
•f(-2) = g(-2)
Answer: D. f(-2)=g(-2)
Step-by-step explanation:
This problem is asking which of the options are correct. Looking at the options, you can see that it is saying that the same x-coordinate on f(x) and g(x) gives you the same solution. Therefore, we want to find the solution of the graph.
Looking at the graph, we can see that the solution is (-2,4). We know this because that is the intersection point of f(x) and g(x). Therefore, D is the correct answer.

what is the definition for Coplanar
Answer:
Step-by-step explanation:
Here, "co" means "shared." Two lines are coplanar if both lie in the same plane (in which case there are three possibilities: the lines intersect in one point, the lines coincide (are one and the same), or the lines never intersect (in which case we call them "parallel."
Suppose we take a look at a three-dimensional space with perpendicular x-, y- and z-axes. If we let one of these three variables be a constant, then the resulting area is a plane (with two-dimenions). if we held z constant, then the plane would be the xy plane, and any two lines lying entirely in this plane are deemed to be "coplanar:" they lie in the same plane.
How do you do this question?
Step-by-step explanation:
f(x) = 38 cos(x²)
Use chain rule to take the derivative.
f'(x) = -38 sin(x²) (2x)
f'(x) = -76x sin(x²)
Use product rule and chain rule to take the derivative.
f"(x) = -76x cos(x²) (2x) + (-76) sin(x²)
f"(x) = -152x² cos(x²) − 76 sin(x²)

How do you determine the last digit in any measured number? Select one: Round up to one digit larger than the smallest precisely known digit or marking. Estimate one digit past the smallest precisely known digit or marking. Consult the unique rule for each type of lab measurement and instrument. Record the digit corresponding to the smallest precisely known digit or marking.
Answer:
Estimate one digit past the smallest precisely known digit or marking
Step-by-step explanation:
To determine the last digit in any measured number : Estimate one digit past the smallest precisely known digit or marking
This is employed mostly when trying to round off a measured or calculated number to a precise number of digits and in other to determine the last digit in the given number we will have to estimate one digit past the smallest precisely known digit
The true statement about how to determine the last digit in any measured number is (b) Estimate one digit past the smallest precisely known digit or marking
A measured number is a number derived from taking measurements (take for instance weight, length, distance etc.)
The number that ends the measured number (i.e. the last digit) is always an estimated digit.
This means that, we have to count one digit past the supposed last digit and then estimate (i.e. approximate)
Hence, the true option is (b)

(2−3)/(3−0)
−1/3
Slope is negative 1/3

five times a number plus 5 has the same value as twice the number plus 10
Answer: x=5/3
Step-by-step explanation:
For this problem, we can use teh information given to write out an equation and solve. Let's use x for the unknown number.
5x+5=2x+10
The left side of the equation comes from the part that says "five times a number plus 5". That is modeled above. The right side of the equation comes from "has the same value as twice the number plus 10".
5x+5=2x+10 [subtract both sides by 2x]
3x+5=10 [subtract both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we have found the unknown number, x=5/3.

The annual precipitation amounts in a certain mountain range are normally distributed with a mean of 85 inches, and a standard deviation of 14 inches. What is the likelihood that the mean annual precipitation during 49 randomly picked years will be less than 87.8 inches?
Answer:
Probability of choosing number = 0.9192
Step-by-step explanation:
Given:
New mean = 87.8
Mean = 85
Standard deviation = 14
Number picked = 49
Find:
Probability of choosing number
Computation:
Probability of choosing number = [New mean - Mean] / [Standard deviation / √Number picked]
Probability of choosing number <= [(87.8-85)]/[(14/7)]
Probability of choosing number = 0.9192
F(x) = x^3 (a) computer f(x)dx (b) computer the approximation L, and T, for n=4, 8, and 16 for the integral in part (a). For each of these, compute the corresponding absolute error.
Answer and Step-by-step explanation:
F(x) = x^3 (a)
then
compute f(x) dx for each of these, compute the corresponding absolute error.
Solution: f(x) = x3
F(x) d(x) = 3x2
The absolute error are ∆x= |x-ẋ|, ∆f=|f(x) – f(ẋ)|
(b) Compute the approximation L, and T, for n=4, 8, and 16 for an integral part.
The linear (L) approximation of function f(x) = x3, n= 4
f(4) = (4)3 = 64 and f”(4) = 3(4)2 = 48
The linear approximation is L4(x) = f (4) + f’(4)(x-4)
= 64 + 48 (x-4)
For n= 8,
f(8) = 512 and f,(8)= 3(8)2= 192
The linear approximate is L8(x) = f(8) + f’(8)(x-8)
Similarly for n= 16 the linear approximate is L16(x) = f (16) + f (16) (x-16)
The approximation for T, trapezoidal rule is:
a ʃb f(x)dx = Tn
for n = 4 the T approximation is:
T4 =a ʃb x3 dx
For n= 8 :
T8 = a ʃb x3 dx
For n= 16 : T16= a ʃb x3 dx.

Step-by-step explanation:
[tex]20 + (y - 10) + 4y \\20 + y -10 + 4y \\20 - 10 + y + 4y \\10 + 5y[/tex]
The simplification form of the expression 20 + (y - 10) + 4y is 5y + 10 after adding like terms.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The linear expression is:
= 20 + (y - 10) + 4y
As we know, the linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.
If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.
After simplifcation:
Adding like terms:
= 5y + 10
Thus, the simplification form of the expression 20 + (y - 10) + 4y is 5y + 10 after adding like terms.
