Answer:
14
Step-by-step explanation:
okay.. so basically you have 2x+6=34 right? so basically i’m gonna tell you the easiest way to do this
so you’re gonna start off by separating the 2x from the 6=34.
now that you’ve done that, let’s focus on the 6=34. so to get your answer, start by subtracting 6 from 34 so (34 - 6 = 28)
now that you’ve got that, keep the number 28 in mind. youre gonna want to take 2 and multiply by x. but 2x = 28, so what do you multiply by 2 to make 28? 14. so x is 14. to check your work, let’s see.
2 x 14 + 6 = 34?
2 x 14 = 28 + 6 = 34.
34 = 34
so, x is 14. hope this helped!
Nancy started the year with $425 in the bank and is saving $25 each week. Sam started the year with $705 but is spending S15 a week. Write a system of equations that model the following situation.
Define cach variables with a "Let" statement, write two equations, and solve completely.
Answer:
Step-by-step explanation:
Let x equal number of weeks and y equal money in the bank.
Nancy, y=425+25x
Sam, y=705-15x
The system of equations:
Nancy: [tex]y=\$425+\$25x[/tex]
Sam : [tex]y=\$705-\$15x[/tex]
Given:
Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
To find:
The system of equations describing the given models.
Solution
1) Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Let the number of weeks Nancy saving her money be 'x'.
Let the total amount of money in Nancy's bank after x weeks be 'y'.
[tex]y=\$425+\$25\times x\\y=\$425+\$25x[/tex]
The equation for Nancy:
[tex]y=\$425+\$25x[/tex]
2)
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
Let the number of weeks Sam spending his money be 'x'
Let the total amount of money left in Sam's bank after x weeks ='y'
[tex]y=\$705-\$15\times x\\y=\$705-\$15x[/tex]
The equation for Sam:
[tex]y=\$705-\$15x[/tex]

Choose the linear inequality that describes the graph. The gray area represents the shaded region.
4x – 6y ≥ 10
4x + 6y ≤ 10
4x + 6y ≥ –10
4x + 6y ≥ 10
please help !
Answer:
4x+6y<=10
Step-by-step explanation:
The linear inequality that describes the graph is 4x+ 6y ≤ 10.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
As, The bold straight line passes through the points (1,1) and (-2, 3).
so, equation of line will be
(y- 1) = (3-1)/ (-2-1) (x-1)
y-1 = 2 / (-3) (x-1)
-3y + 3 = 2x - 2
-3y -2x = -5
If we multiply by 2 both side we get
-6y - 4x = -10
4x+ 6y= 10
So, the required inequality for gray area is 4x+ 6y ≤ 10.

The total cost of making a daily taco special for a restaurant is represented by the function C (t) = 2.5t + 1 , where t is the number of tacos made. How does the total cost change for every taco special the food truck makes?
A. The total cost increases by $1.
B. The total cost increases by $2.50.
C. The total cost decreases by $1.
D. The total cost decreases by $2.50.
Answer:
C. The total cost increases by $2.50
Step-by-step explanation:
This is because 1 dollar is constent--- you will always have 1 dollar.
However 2.5 is the change, you have to times a number to get the answer.
EX:
(t) = 2.5t + 1
(4) = 2.5( 4) + 1 ----- plug in 4 for t
= 10 +1
= 11
The is the multiplyer or change is the 2.5t
and when you graph it it will almost always be the slope of the line.
Isabel’s class has collected 90 cans in a food drive. They plan to sort the cans into n bags, with an equal number of cans in each bag. Write an expression to show how many cans there will be in each bag.
Answer:
90/n
Step-by-step explanation:
There are 90 cans, and each bag MUST have an equal amount of cans, so if we had, let's say 2 bags, then there would be 45 bags. We got this by doing 90/2. 2 being n, the expression would be 90/n.

Solve the system by substitution.
y = 5x
y = 9x + 4
Answer:
(-1, -5)
Step-by-step explanation:
[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)

In 8 hours if Martha writes 2 essays, how many essays can she write in 15 hours?
Answer:
Martha can write 3.75 essays in 15 hours. (Which is a lot for me)
Step-by-step explanation:
First, I divide 2 by 8.
2 ÷ 8 = 0.25
Next I multiply 0.25 by 15.
0.25 * 15 = 3.75
So, the answer is 3.75
Hope this helps! :)
Step-by-step explanation:
in 8 hours she wrote = 2 essay
in 1 hour she wrote = 2/8 = 1/4
in 15 she wrote = 15 × 1/4 = 15/4 or 3.75 essays .

What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:
Step 1: You must divide the numerator of the fraction by the denominator of the fraction.
Step 2: Now you must add the quotient obtained to the Whole number part.
So, you get:
3 + 1/4
=3 + 0.25
= 3.25
Then, the scale image that maps "Figure a" onto "Figure b" is:
1: 3.25
Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .
Therefore, you get that the result is:
x = 3 * 3.25
or, x = 9.75
Hence, The solution is : the value of x is x = 9.75.

Answer:
Lots of "ifs" here.
A=bh/2 is the formula for the area of a triangle.
A=bh is the formula for the area of a rectangle or a parallelogram.
If the 6 & 4 area the base & height of a rectangle, then (6)(4) = 24 in^2
If the 6 & 10 are the base and height of a triangle, then 1/2(6)(10) = 30 in^2

What is the sign of f on the interval?
The function f(x) will be sometimes positive and sometimes negative on the interval
Option (3) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.
Given function:
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.
Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.
Hence, the function f is sometimes positive and sometimes negative on the interval.

y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y
Answer: x = 1 and y = -1
Step-by-step explanation:
Since both equations are equal to y, that means the equations are both equal to each other
5x - 6 = -4x + 3
Solve for x how you would traditionally do it with any other one-variable equation
9x = 9
x = 1
Plug the now known x value into either equation and you will get your y value.
5(1) - 6 = -1
-4(1) + 3 = -1
