y = 2x
x = -y + 6
help meee !
Answer:
x = 2
y = 4
Step-by-step explanation:
y = 2x
x = -y + 6, y = 6 - x
substitute for y:
2x = 6 - x
3x = 6
x = 2
y = 4
Find the volume of the cube. *
Answer choices: 30 1/2, 33 3/4, 31 1/4, 32 1/3
Answer:
volume = wide x length x deep
= 3{1/3} ft x 2{1/2} ft x 3{3/4}ft
= 10/3ft x 5/2ft x 15/4ft
= (10 x 5 x 15)/(3 x 2 x 4) ft^3
= 125/4 ft^3
= 31{1/4} ft^3

Please write the function(x) from the given rules:a. Twice the input value plus three. B. The input value minus five. C. To get the output, multiply the input by two, then add four.
Answer:
A) f(x) = 2x + 3
B) f(x) = x - 5
C) f(x) = 2x + 4
Step-by-step explanation:
To find - Please write the function(x) from the given rules:
A) Twice the input value plus three.
B) The input value minus five.
C) To get the output, multiply the input by two, then add four.
Proof -
Let us assume that the input = x
The output = f(x)
Now,
A)
f(x) = 2x + 3
B)
f(x) = x - 5
C)
f(x) = 2x + 4
Next Question I only have 40 minutes to complete the rest of these. Help Asap Please. Again I will award 100pts and Brainly to whoever can get me the slope intercept form to these two cordinate points. This is timed. And I risk failing the class if I don't get these questions answered. Plz help.
Answer:
y=-2x+1
Step-by-step explanation:
First, you calculate the slope, which is rise over run: -9+5 / 5-3 = -2. Then, find b by substituting the coordinates (of either one point) into the slope-intercept formula, y = mx + b.
Answer:
Step-by-step explanation:
The slope intercept form of a line is
y=mx+b, where m=slope and b= y intercept
The slope of a line is defined as
m=(y2-y1)/(x2-x1), in this case we have points (3,-5) and (5,-9)
m=(-9-(-5))/(5-3)
m=-4/2
m=-2, so our line is now
y=-2x+b, using point (3,-5) we can now solve for b
-5=-2(3)+b
-5=-6+b
1=b so the completed line is
y=-2x+1
What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = x + 6
Step-by-step explanation:
Line is passing through the points (0, 6) & (1, 7)
So, y-intercept (b) = 6
Slope (m) [tex] =\frac{(7 - 6)}{(1 - 0)} = \frac {1}{1} = 1[/tex]
Equation of line in slope-intercept form is given as:
y = mx + b
Plugging the values of m and b in the above equation, we find:
y = 1*x + 6
y = x + 6

91X + 637 = 273 Find X
pls help?
Answer:
X = -4
Step-by-step explanation:
91x + 637 =273
First subtract 637 from both sides: 91x = -364
Then, divide both sides by 91 to get X by itself: X = -4
for the arthritic sequence 5,9,13,17,21,... how many terms would you need to get to 129
9514 1404 393
Answer:
32
Step-by-step explanation:
The first term is 5 and the common difference is 9-5=4, so the n-th term is ...
an = a1 +d(n -1)
an = 5 +4(n -1) = 4n +1
Then the term number for the term 129 is ...
129 = 4n +1 . . . . . put the given value in the formula
128 = 4n . . . . . . . subtract 1
32 = n . . . . . . . . . .divide by 4
The 32nd term is 129.

2x+3=x-4 what is the question
Answer:
x = - 7
Step-by-step explanation:
Step 1:
2x + 3 = x - 4 Equation
Step 2:
x + 3 = - 4 Subtract x on both sides
Answer:
x = - 7 Subtract 3 on both sides
Hope This Helps :)
Answer:
x = -7
Step-by-step explanation:
Given Equation :-
2x + 3 = x - 4Solution :-
Step 1 :- Subtract x from both sides
2x - x + 3 = x - x - 4x + 3 = - 4Step 2 :- Move constant to the right hand side and change their sign.
x = - 4 - 3Step 3 :- Combine like terms
x = -7
[tex] \sqrt{ {4 a}^{2} + {12a}^{2} } [/tex]
Answer:
The answer is 4a
Step-by-step explanation:
1) Simplify 4a² + 12a² to 16a².
[tex] \sqrt{ {16a}^{2} } [/tex]
2) Use this rule:
[tex] \sqrt{ab} = \sqrt{a} \sqrt{b} [/tex]
[tex] \sqrt{16} \sqrt{ {a}^{2} } [/tex]
3) Since 4 × 4 is 16, the square root of 16 is 4.
[tex]4 \sqrt{ {a}^{2} } [/tex]
4) Simplify.
[tex]4a[/tex]
Therefor, the answer is 4a.

Help me with this!!!
Answer:
z = 9
Step-by-step explanation:
JH is a perpendicular bisector of Δ IJK.
Thus the triangle is isosceles with
JK = JI , that is
7z = z + 54 ( subtract z from both sides )
6z = 54 ( divide both sides by 6 )
z = 9
