How do u graph y=15x+35?
Hey there!
This is slope intercept form, where y=mx+b, where b is the y-intercept (where the line hits the y-axis) and the slope (rate of change).
If you wanted to graph this line, we can see that the y intercept in 35. Therefore, our line is going have one point on (0,35). Our slope is 15, which is positive, showing that our line will go up. Because the slope is fifteen, for every single increase of 1 there is in x, there will be an increase of 15 in y. This will give us points like (1,15) (2,30) (3,45). Therefore, this will be a very steep line.
You can use this info to graph your line.

Determine whether the two expressions are equivalent. If so, tell what property is applied.
(20 – 4) – 2 and 20 – (4 – 2)
Both expressions (20 – 4) – 2 and 20 – (4 – 2) are equivalent, simplifying to 14. The equivalence exemplifies the Associative Property of Addition.
The question asks to determine whether the two expressions (20 – 4) – 2 and 20 – (4 – 2) are equivalent, and if so, to identify the property applied. To determine equivalence, we need to simplify both expressions. The first expression, (20 – 4) – 2, simplifies to 16 – 2 which equals 14. The second expression, 20 – (4 – 2), simplifies to 20 – 2 which also equals 14. Therefore, both expressions are equivalent, and the property applied here is the Associative Property of Addition, which allows us to change the grouping of the numbers we're adding (or subtracting, in this case) without changing the result.

The length of SK = 10 units while the length of BK = 8.6602 units.
Step-by-step explanation:
Step 1:
In the given triangle, there are two right-angles triangles with 60° angles. The central line BK is the opposite side for both the triangles. For triangle RK the hypotenuse's length is 10 m. Assume BK = x units and SK = y units.
Step 2:
So first we calculate the length of BK (x).
As we have the values of the angle of the triangle and the hypotenuse, we can calculate the sine of the angle to determine the value of x.
[tex]sin R = \frac{oppositeside}{hypotenuse}, sin 60 = \frac{x}{10}.[/tex]
[tex]sin 60 = 0.86602, x = 0.86602 (10) = 8.6602 units.[/tex]
So x = BK = 8.6602 units.
Step 3:
So now we calculate the length of SK (y).
As we have the values of the angle of the triangle and the opposite side's length, we can calculate the sine of the angle to determine the value of y.
[tex]sin S = \frac{oppositeside}{hypotenuse}, sin 60 = \frac{86.602}{y}.[/tex]
[tex]sin 60 = 0.86602, y = \frac{8.6602}{0.86602} = 9.999units = 10 units[/tex]
So y = SK = 10 units.
Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A E, B F, and C D. The length of line segment A G is 2 x + 10, the length of line segment F G is 2 x minus 1, and the length of line segment G B is 3 x + 6.
G is the centroid of triangle ABC.
What is the length of AE?
units
Answer:
The length of AE is 39 units.
Step-by-step explanation:
Given:
G is the centroid of a triangle ABC.
Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments AE, BF, and CD.
The length of line segment A G is 2 x + 10, the length of line segment F G is 2 x minus 1, and the length of line segment G B is 3 x + 6
To Find: Length of the AE.
The centroid of the triangle is always cut the line in the ratio of 2:1. For clarification, the image is provided.
Hence,
G divides the line BF into a 2:1 ratio.
Thus,
[tex]\begin{aligned}&2FG=BG\\&2(2x-1)=3x+6\\&4x-2=3x+6\\&x=8 \end{aligned}[/tex]
Also,
G divides the line AE into a 2:1 ratio.
Therefore,
[tex]AG=2GE\\GE=AG/2[/tex]
Line segment AE is the sum of AG and GE.
Thus,
[tex]AE=AG+GE\\AE=AG+AG/2\\AE=3AG/2\\AE=3(2x+10)/2\\AE=39[/tex]

https://brainly.com/question/24182367?referrer=searchResults
The length of AE is 9 units.
Given that G is the centroid, it divides each median into two segments with the ratio of 2:1, where the longer segment is toward the vertex and the shorter segment is toward the midpoint of the opposite side.
Let's denote the length of AG as a, the length of BG as b, and the length of FG as c. According to the given information:
1. AG = 2x + 10
2. FG = 2x - 1
3. BG = 3x + 6
We know that AG = 2GE and BG = 2GE. Thus:
[tex]\[ AG = 2GE \implies GE = \frac{AG}{2} = \frac{2x + 10}{2} = x + 5 \]\[ BG = 2GE \implies GE = \frac{BG}{2} = \frac{3x + 6}{2} = \frac{3}{2}x + 3 \][/tex]
Since GE is common, we can equate the expressions:
[tex]\[ x + 5 = \frac{3}{2}x + 3 \][/tex]
Solving for x:
[tex]\[ \frac{1}{2}x = 2 \][/tex]
x = 4
Now that we've found the value of x, we can substitute it back into the expressions for AG and FG to find their lengths:
AG = 2x + 10 = 2(4) + 10 = 18
FG = 2x - 1 = 2(4) - 1 = 7
Now, we know that AE = AG - GE:
AE = AG - GE = 18 - (x + 5) = 18 - (4 + 5) = 18 - 9 = 9
So, the length of AE is 9 units.

2x + y = 3
4x + 3y = 1
Answer:
x = 4, y = -5 OR (4, -5)
Step-by-step explanation:
Step 1: Solve for y in the first equation
2x + y - 2x = 3 - 2x
y = 3 - 2x
Step 2: Plug in that into the second equation to get x
4x + 3(3 - 2x) = 1
4x + 9 - 6x = 1
-2x + 9 - 9 = 1 - 9
-2x / -2 = -8 / -2
x = 4

An electronics store reduced the price of a TV from $1000 to $880. What was the percent of decrease?
Answer:
12% decrease
Step-by-step explanation:
think of 1000 as 100% and thin 880 as 88% subtract those 12%
The price decrease from $1000 to $880 represents a 12% decrease. This is figured out by taking the difference in price, dividing it by the original price, and then multiplying by 100%.
Explanation:The percentage decrease is calculated by taking the difference in price divided by the original price, and then multiplying by 100 to get a percentage. In this case, the difference in price is the original price minus the sale price. This would be $1000 - $880 = $120. So, the formula would be ($120/$1000)*100. The calculated percentage decrease is 12%, meaning the price of the TV has been reduced by 12%.

A store starts the day with 36 packages of juice boxes. Each package contains the
same number of juice boxes. By the end of the day, there are only 8 packages of
juice boxes left.
Part A
Write an expression with two terms to represent the number of juice boxes the
store sold.
Part B
Simplify your expression to create an equivalent expression.
Step-by-step explanation:
Given:
Number of packets at the beginning of the day, Nb = 36 packets
Number of packets at the end of the day, Ne = 8 packets
A.
Number of packets sold, Ns = Nb - Ne
36 - Number of packets sold, Ns = Ne
8 = 36 - Ns
Ns = 28
B.
8 = 36 - Ns
8 = 36 - 28
Final answer:
The expression representing the number of juice boxes sold is 28 multiplied by x, where x is the number of juice boxes per package. Since x is unknown, the expression cannot be simplified further and remains as 28 × x.
Explanation:
Part A: Representing the Number of Juice Boxes Sold
To represent the number of juice boxes sold, let's denote the number of juice boxes in each package as x. The store started with 36 packages and ended with 8. We are looking for the number of juice boxes in the packages that were sold. The expression is:
28 × x (since 36 - 8 = 28, and 28 packages were sold)
Part B: Simplifying the Expression
To simplify the expression, we do not have further information to simplify 28 × x more because x represents an unknown number of juice boxes per package. The simplified expression remains as:
28 × x
