Answer:
(-3, 2)
Step-by-step explanation:
x + y = -1 = x = -1 - y
-3( -1 -y ) -4y = 2
4 + 3y - 4y = 2
-y + 4 = 2
-y = -2
y = 2
x + 2 = -1
x = -3

What is the value of x?
Answer:
x = 7°
Step-by-step explanation:
The sum of all octogon's angles equals 1080°
Let's solve your equation step-by-step.
8(16x + 23) = 1080
Step 1: Simplify both sides of the equation.
8(16x + 23)=1080
(8)(16x) + (8)(23) = 1080(Distribute)
128x + 184 = 1080
Step 2: Subtract 184 from both sides.
128x + 184 − 184 = 1080 − 184
128x = 896
Step 3: Divide both sides by 128.
128x/128 = 896/128
x = 7°

In the coordinate plane, line p has a slope of 8 and y-intercept (0,3). What are the slope and y-intercept of line r?
Answer:
y = 8x + 3
Step-by-step explanation:
The line we are describing here is line p;
slope of line p = 8
y- intercept = (0,3)
y-intercept of a line is the point where it crosses the y-axis. At this point, the x = 0
So;
Slope of the line = 8
y-intercept = 3
Equation of the line;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
y = 8x + 3

What is the equation of the line that passes through the point (2,−1) and has a slope of 3/2
Given :-
A line having a slope of 3/2 passes through (2,-1) .
To Find :-
The equation of the line .
Answer :-
According to the question ,
m = 3/2
Point = (2,-1)
We know Point slope form of the line as ,
y - y¡ = m ( x - x ¡ )
Substitute ,
y - (-1) = 3/2 ( x - 2 )
y + 1 = 3/2x - 3/2*2
y +1 = 3/2x - 3
2( y +1) = 3/2x *2 - 3*2
2y + 2 = 3x - 6
3x -2y -8 = 0

If a worker can do his job in 5 hours, and a student can do the same job in 8 hours, what part of the work is left to finish after two hours of work? NOTE: THEY WORKED TOGETHER
ANSWER: FRACTIOn
Answer:
Part of work left to finish after two work hours is 7/20
Step-by-step explanation:
Firstly, we need to calculate their joint work rate
That will be;
1/(1/5 + 1/8) = 1/(13/40) = 40/13
This means that they will complete the task in 40/13 hours
1 whole part takes 40/13
x part will take 2 hours
x * 40/13 = 2
40x = 26
x = 26/40
So the part that will be completed in two hours is 26/40
This means that the part left to complete will be:
1 - 26/40 = 14/40 = 7/20
Answer:
7/20
Step-by-step explanation:
you need to find what is left, not how much they did (which is 13/20)

A line with a slope of -4 has a coordinate of (0,3). If the other coordinate is (6,t),
find the value of t. Plz show work
Answer:
Alrighty! So this is what we know:
Slope (m) = (-4)
Co-ordinate (0,3)
Co-ordinate 2 (6,t)
t = ?
Let's find our equation...
y=mx+b <-- just plug what we know in...
3=(-4)0+b
3=0+b
b=3
We just found b! woohoo
Now what is t? t is a value we need to know WHICH IS the y value of a co-ordinate that corresponds to when x is 6, as we know a co-ordinate is expressed as --> (x value, y value).
SO-
t=y
plug it in our equation...
y=mx+b
t=(-4)x+3
t=(-4)(6)+3
t=(-24)+3
t=(-21)
SOOOOOOOO WE HAVE OUR T!! just write a therefore statement like "therefore the value of t is -21." and you're set! hope this helped, any questions? ask in the comment section. :)

Shelby spends 2/7 of her salary on her monthly rent and has $3455 left over. How much does she spend on her rent each month?
Answer:
$1382
3455 is 5/7 of salary so divide 3455/5 = 691
then multiply 691x2 because rent is 2/7 of salary
691x2 = 1382
Order the lengths 7/8 feet, 0.8 feet, and 15/16 feet from least to greatest.
Answer:
Step-by-step explanation:
Convert fractions to decimals
7/8 = 0.875
0.8
15/16 = 0.9375
0.8 < 0.875 < 0.9375
0.8 < 7/8 < 15/16
Which expression is equivalent to square root of 80
Answer: 2nd one down
Step-by-step explanation:
Consider functions f and g.
f(x) = 3/x + 1
What is the value of f(g(1))
A. 9
B. 3/2+1
C. 0
D. 1
Answer:
D. 1
Step-by-step explanation:
You are given the values of x that correspond to g(x).
Then you are given f(g(1)), the function of f, the function of g(x) at 1.
When x is 1, g(x) is 0.
f(x) is 3 times the square root of x plus 1.
Since x is now 0, three times the square root of 0 is still zero. The one remains.
Given function → [tex]f(x)=3\sqrt{x} +1[/tex]
In the picture attached, for every value of 'x', value of function 'g' has been given.
For x = 1, g(1) = 0
Now substitute the value of g(1) in function 'f',
[tex]f(g(1))=f(0)[/tex]
Since, [tex]f(x)=3\sqrt{x} +1[/tex]
Therefore, [tex]f(0)=3\sqrt{0}+1[/tex]
[tex]=1[/tex]
Hence, Option D will be the correct option.

solve for z
−p⋅(51+z)=dz+84
Answer:
z≠0
Step-by-step explanation:
dz+84=-p(51+z)
dz+84-84=-p(51+z) -84
dz=-p(51+z) -84
dz/z=-p(51+z) /z-84/z
The value of z is (84 + 51p) / (d - p).
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
-p(51 + z) = dz + 84
Remove the parentheses.
-51p - pz = dz + 84
Subtract dz on both sides.
-51p - pz - dz = 84
Add -51p on both sides.
--pz - dz = 84 + 51p
z (-p + d) = 84 + 51p
z = (84 + 51p) / (d - p)
Thus,
The value of z is (84 + 51p) / (d - p).
