What is the value of y in the solution to the system of equations?
One-thirdx + One-fourthy = 1
2x – 3y = –30
Answer:
y-value = 8
Step-by-step explanation:
1/3x + 1/4y = 1 is the same as 4/12x + 3/12y = 1
which is the same as (4x + 3y)/12 = 1
which is the same as 4x + 3y = 12
add both equations and the 'y' will cancel and you will have 6x = -18
x = -3
2(-3) - 3y = -30
-6 - 3y = -30
-3y = -24
y = 8
Answer:8

3x^2+ 4x + 5 for x = -2
is this a function?
ignore the graph above the one with the dots lol
Answer:
No.
Step-by-step explanation:
Use a vertical line test.
Vertical line test: If you can draw a vertical line and it does not cross two points in the line, then it is a function.
So, we draw a line.
Draw it through 9,0
It intercepts two points so No. This is not a function.
Hope this helps plz hit the crown :D

A circle is graphed on a coordinate grid. Its center is at (3, 4), and the circle passes through point (3, 1). What is the approximate area, in square units, of the circle? (Use 3.14 for π.)
Answer:
it is either 18.84 or 31.40
Step-by-step explanation:
just do it in your head
The area of the circle is 28.26 square units
The center of the circle is given as:
[tex](a,b) = (3,4)[/tex]The circle passes through the following point
[tex](x,y) = (3,1)[/tex]Start by calculating the radius using the following distance formula
[tex]r = \sqrt{(x -a)^2 + (y - b)^2}[/tex]
So, we have:
[tex]r = \sqrt{(3 -3)^2 + (4 - 1)^2}[/tex]
[tex]r = \sqrt{9}[/tex]
Square both sides
[tex]r^2 = 9[/tex]
The area of the circle is then calculated as:
[tex]Area = \pi r^2[/tex]So, we have:
[tex]Area = 3.14 \times 9[/tex]
[tex]Area = 28.26[/tex]
Hence, the area of the circle is 28.26 square units

Daniel can spend no more than $40 at the fair. If admission into the fair is $10 and the rides cost $1.50 each, which inequality represents the greatest number of rides Daniel can go on?
A. 10r + 1.50 ≥ 40
B. 1.50r + 10 ≤ 40
C. 1.50r + 10 <40
D 10r+1.50<40
Explain your reasoning and solve the inequality :
Answer:
B
Step-by-step explanation:
The sum spent has to be either equal to or less than 40. So r many rides, each of them being 1.50, plus 10 dollars has to equal to less or equal to 40 dollars.
Answer:
The answer is B
The greatest number of rides Daniel can go on is 20.
Step-by-step explanation:
Total: The same or less than 40
Fair Admission: 10
ride: 1.50x
40 ≤ 10 + 1.5r
To solve:
40 ≤ 10 + 1.5r
40 - 10 ≤ 10 + 1.5r - 10
30 ≤ 1.5r
30 ÷ 1.5 ≤ 1.5r ÷ 1.5
20 ≤ r
The greatest number of rides Daniel can go on is 20.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Step-by-step explanation:
a college spends 40% of an individual's tuition on salaries and the remainder on other costs if they spend 1,800 on other costs how much is an individual's tuition?
Answer:
$3000
Step-by-step explanation:
If the remainder is spent on other costs, then that means 60% of the tuition as spent on other costs.
To find the total tuition, divide 1800 by 0.6:
1800/0.6
= 3000
So, their tuition was $3000
through: (-3, -4) and (2, 1)

The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Write an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x). Show or explain how you found your equation.
Answer:
y = 9x/5 + 50
Step-by-step explanation:
We are represent the information as coordinate (x,y)
If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)
Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;
(150, 320)
Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope;
m = y2-y1/x2-x1
m = 320-230/150-100
m = 90/50
m = 9/5
Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c
230 = 9/5(100)+c
230 = 9(20)+c
230 = 180 + c
c = 230-180
c = 50
Get the required equation
y = mx+c
y = 9/5 x + 50
Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50
it's a two step equation
Answer: -15=x
Step-by-step explanation: subtract 10 on each side then divide -5 on both sides to isolate the variable
-5x=+10-85
5x=-75
x=-75/5=> x= -15
the slope and y intercept of y=-8x
Answer:
m = -8
b = 0
Step-by-step explanation:
In slope intercept form [ y = mx + b ], m = slope and b = y-intercept.
We aren't given a b value, but we are given a m value which is -8.

How do you solve for X?
Answer:
<L+<M+<N=180
<NLM and <XLN are supplementary meaning their angle measure add to 180.
therefore,44+46+L=180
90+L=180
l=90
If l=90 then the <NLX is also 90 since they are supplementary angles
therefore, 3x+42=90
3x=48
x=16
