true or false?
and please tell me how to solve it❤
Answer:
True
Step-by-step explanation:
[tex]\frac{x - y }{x + y}=-1[/tex] ---------------(I)
Cross multiply
x - y = -1*(x + y)
x - y = (-1)*x + y * (-1)
x - y = -x - y
x - y + x = - y
2x - y = -y
2x = -y + y
2x = 0
x = 0
Plugin x = 0 in (I)
[tex]\frac{0-y}{0+ y} = -1\\\\\frac{-y}{y}=-1\\\\-1 = -1[/tex]
So , true
Step-by-step explanation:
This is true. -1 =-1

I'm assuming you've already learned the special properties of a 30-60-90 triangle.
By drawing a 30-60-90 triangle by constructing line BC, and using the special proportions that come from it, we can find that
AB=AC/2=36/2=18
and
BC=AB*[tex]\sqrt{3}[/tex]=[tex]18\sqrt{3}[/tex]
A line passes through the point (8, -7) and has a slope of
3/4
Write an equation in slope-intercept form for this line.
Answer:
y = 3/4x - 13
Step-by-step explanation:
As we already know the slope, we just need to find the y-intercept.
y = 3/4x +b
-7 = 3/4(8) + b
-7 = 6 + b
-13 = b
y = 3/4x - 13
Which equation best represents the relationship between x and y in the table below?
Answer:
y = x² + 5
Step-by-step explanation:
When x = 1:
y = x² + 5
y = 1² + 5
y = 6
When x = 2:
y = x² + 5
y = 2² + 5
y = 9
When x = 3:
y = x² + 5
y = 3² + 5
y = 14

Which lists all the multiples of 6 that are less than 20?
6, 9, 12, 15, 18
6, 12
6, 12, 18
6, 12, 18, 24
Answer:
C
Step-by-step explanation
An easy way to figure is to see if all of the numbers in that group can be divided by 6.
In this first one, 9 and 15 are not divisible by 6.
In the second one 6, 12 are multiples ok 6 but there is one more.
In the last one 24 is over the 20 limit.
So, C is correct.

Alberto invests $4,571 in a retirement account with a fixed annual interest rate of 3% compounded 6 times per year. What will the account balance be after 18 years?
A) $7,833.32
B) $7,162.06
C) $7,602.38
D) $6,985.59
Answer:
A) $7,833.32
Step-by-step explanation:
Given data
Principal= $4,571
Rate=3%
n= 6
Time = 18 years
The expression for compound interest is
A=P(1+r/n)^nt
substitute
A= 4571(1+0.03/6)^6*18
A= 4571(1+0.03/6)^6*18
A= 4571(1+0.005)^6*18
A= 4571(1.005)^6*18
A= 4571(1.005)^108
A=4571*1.7136
A=$7832.86
Hence the approximate amount is A) $7,833.32

NO LINKS OR I WILL REPORT!!! But pls help meee pls I’ve posted this so many times just help me out pls Calculate the scale factor of ABC to DEF. Enter answer as a whole number
or as a fraction in lowest terms, using the slash mark (/) for the fraction bar.
Answer:
The scale factor is 8.
Segment AC is congruent to segment FD, and the other 2 sides are congruent because this is an isosceles triangle.
Triangle ABC can transform to Triangle DEF after a scale factor (multiplying each side by the same value) of 8.
Hope this helps!

Brandon plowed snow from 84 driveways in 7 days. He plowed the same number of driveways each day. Tell whether
the statement is True or False.
If Brandon continues at the same rate, he will plow 120 driveways in 12 days.
The whole statement is true.
Some of the statement is false.
Answer:
Some of the statement is false.
Step-by-step explanation:
84 driveways / 7 days = 12 driveways per day.
12 driveways x 12 days = 144 driveways
