Answer:?
Step-by-step explanation:
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
Step-by-step explanation:
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

Answer:
The coordinates are (1.4, -0.8)
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

The disks of polish kielbasa measure to be 1/4 of a inch. If there are 36 disks altogether, what is the total length of polish keilbasa being using? White a number sentence to go with your answer. Write it in the simples form
Answer:
9 inches
Step-by-step explanation:
The disks of polish kielbasa measure to be 1/4 of a inch. If there are 36 disks altogether, what is the total length of polish keilbasa being using?
The total length of polish kielbasa is calculated as:
1/4 of 36 disks
= 1/4 × 36 disks
= 9 inches
The total length of polish keilbasa being used is 9 inches
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

1 Evaluate the expression 2a + b - 3 when a=5 and b=2. Please click on "show your work" to set up the problem and show your work. Then, enter your answer in the box to the right. You must complete both of these steps.
Answer:
9
Step-by-step explanation:
From the question,
We are to evaluate the expression : 2a + b - 3 when a=5 and b=2.
We substitute 5 for a and 2 for b in the given expression
2a + b - 3
= 2(5) + 2 - 3
= 10 + 2 - 3
= 12 - 3
= 9
Can someone really help me please!
Step-by-step explanation:
The formula for area of a rectangle is A= length times width. They gave you the area of the entire rectangle. But because this is a shape with a cutout, you still need the area of the missing section.
A= 1*4 = 4 units
Now subtract that from 49.
A=49 - 4= 45 square units
Answer:
49-4 = 45
Step-by-step explanation:

[tex]\begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} -3 & 0\\\cline{1-2} -2 & 1\\\cline{1-2} -1 & 2\\\cline{1-2} 0 & 3\\\cline{1-2} 1 & 4\\\cline{1-2} 2 & 5\\\cline{1-2}\end{array}[/tex]
non-proportional
Step-by-step explanation:
Given equation:
[tex]y=x+3[/tex]
Create a table of ordered pairs using the given equation:
[tex]\begin{array}{| c | c | c |}\cline{1-3} x & x+3 & y\\\cline{1-3} -3 & -3+3 & 0\\\cline{1-3} -2 & -2+3 & 1\\\cline{1-3} -1 & -1+3 & 2\\\cline{1-3} 0 & 0+3 & 3\\\cline{1-3} 1 & 1+3 & 4\\\cline{1-3} 2 & 2+3 & 5\\\cline{1-3}\end{array} \implies \begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} -3 & 0\\\cline{1-2} -2 & 1\\\cline{1-2} -1 & 2\\\cline{1-2} 0 & 3\\\cline{1-2} 1 & 4\\\cline{1-2} 2 & 5\\\cline{1-2}\end{array}[/tex]
Graph
As the given equation is linear, plot two of the ordered pairs and draw a straight line through them. (See attachment).
Proportional Relationship
A relationship in which two quantities vary directly with each other.
y varies directly as x:
[tex]y=kx[/tex]
(where k is some constant)
To find if the relationship is proportional using the table, find the ratio [tex]\dfrac{y}{x}[/tex] of each row. If the ratio is the same, the relationship is proportional.
[tex]\begin{array}{| c | c | c |}\cline{1-3} x & y & \dfrac{y}{x}\\\cline{1-3} -3 & 0 & 0\\\cline{1-3} -2 & 1 & -0.5} \\\cline{1-3} -1 & 2 & -2 \\\cline{1-3} 0 & 3 & \text{-}\\\cline{1-3} 1 & 4 & 4\\\cline{1-3} 2 & 5 & 2.5\\\cline{1-3}\end{array}[/tex]
Graphs of proportional relationships pass through the origin (0, 0).
Therefore, the relationship is non-proportional because:
The ratios of y/x of each row of the table are not the same.The graph does not pass through the origin.There is the addition of a constant in the given equation, which means that y does not vary directly as x.Solve the equation.

Answer:
x = -8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
x + 5 = -3
Step 2: Solve for x
Subtract 5 on both sides: x = -8Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -8 + 5 = -3Add: -3 = -3Here we see that -3 does indeed equal -3.
∴ x = -8 is the solution to the equation.
Answer:
[tex]x=-8[/tex]
Step-by-step explanation:
Subtract 5 from both sides.
[tex]x=-3-5[/tex]
Simplify [tex]-3 -5[/tex] to [tex]-8[/tex]
[tex]x=-8[/tex]
let check if the answer is correct
[tex]x+5=-3[/tex]
Let [tex]x=-8[/tex]
[tex]-8+5=-3[/tex]
Simplify [tex]-8+5[/tex] to [tex]-3[/tex]

A plumber charges a one-time fee of $50 plus a fixed hourly rate (h) in dollars. The plumber works at a customer's house for 2 hours and charges a total of $100. Find the hourly rate the plumber charges.
Answer:
$25 an hour
Step-by-step explanation:
use this equation y = hx + 50
y is the money earned and x is the hours worked
plug in 100 for y and 2 for x
100 = 2h + 50
solve for h
50 = 2h
25 = h
he charges $25 an hour
