Answer:
y=5
Step-by-step explanation:
3y-5=2y
3y-2y=5
y=5
Answer:
y=5
Step-by-step explanation:
3y-5=2y
/add 5 to both sides/
3y-5+5=2y+5
simplify
3y=2y+5
subtract 2y from both sides
3y-2y=2y+5-2y
simplify
y=5
The ratio of the perimeters of two similar triangles is 4:3. What are the areas of these triangles if the sum of their areas is 130 cm^2?
Answer:
the areas of these triangles are 83.2cm² and 46.8cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:
4²:3²
16:9
2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:
130(16/16+9)
130(0.64)
=83.2cm²
3. The area of the smaller triangle is:
130(9/16+9)
130(0.36)
46.8cm²

Answer:
y=1/3x+3
Step-by-step explanation:
We can write this in a y=mx+b format.
b is the y-intercept and m is the slope.
The y-intercept is where x=0, or where the line intersects the y-axis. We can see that there is a point on the y-axis: (0,3). Therefore, the y-intercept, or b, is 3.
So far, we have y=mx+3.
Now we can find the slope with rise over run. (rise being the change in y and the run being the change in x.)
From one point to the other, it goes up 1 (the rise) and over 3 (the run).
m=rise/run=1/3.
y=1/3x+3.
Hope this helped.

Identify the restrictions on the domain of f(x) = quantity x minus 1 over quantity x plus 4.
A. x ≠ −4
B.x ≠ 4
C. x ≠ −1
D. x ≠ 1
The restriction is that x ≠ -4 is not in the domain of the given function.
What is a function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The given function is
[tex]f(x)=\frac{x-1}{x+4}[/tex]
This is not defined when the denominator is zero.
Hence the restriction is on the denominator.
This implies that
[tex]x+4 \neq 0[/tex]
[tex]x\neq-4[/tex]
The restriction is that x ≠ -4 is not in the domain of the given function.

Solve for x in the picture please.
Answer:
X=20
Step-by-step explanation:
The 3 angles all add up to 180º because they are a straight line.
3x + 80 + 2x = 180
5x + 80 = 180
5x + (80-80) = 180-80
5x = 100
5x/5 = 100/5
X=20
