The product of −2 and a number x is greater than 30. Whats the solution of the inequality.
Answer: x < -15
Step-by-step explanation:
(-2)*(x) > 30
x < -15 The inequality reverses direction when a negative number is used in the manipulation (we divided by -2).

The second one is right
Step-by-step explanation:
anyone help, im stuck
Answer:
The third one
Step-by-step explanation:
Since, 1 can be represented by x we can make an equation
2 can be represented y
and 4 can be represented by x
Since x + y = 180 and x + z = 180
y = z
Or 2 = 4

1. What is the vertex for the following quadratic function, y = 2x^2 - 4x + 5?
A). (1,3)
B). (3, 1)
C) (0,5)
D). (2,5)
Answer:
A
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = 2x² - 4x + 5 ← is in standard form
with a = 2 and b = - 4 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{-4}{4}[/tex] = 1
Substitute x = 1 into the equation for corresponding value of y
y = 2(1)² - 4(1) + 5 = 2 - 4 + 5 = 3
vertex = (1, 3 ) → A
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Solve the following equation algebraically. Show your work. 17 = − 13 − 8 x
The solution to the given expression is -15/4
Equations are expressions separated by an equal sign.
Given the expression 17 = -13 -8x
Add 13 to both sides
17 + 13 = -13 - 8x + 13
30 = -8x
Swap sides
-8x = 30
Divide both sides by -8
-8x/-8 = -30/8
x = -30/8
x = -15/4
Hence the solution to the given expression is -15/4

Can someone help me please
Step-by-step explanation:
it just means to convert these equations into function definitions.
and a function looks like
y = ... something with x, factors, other functions, constants
1)
x + y = z
y = -x + z or z - x
2)
x - y = z
x - z = y or y = x - z
3)
x × y = z
y = z/x
4)
x/y = z
x = z × y
x/z = y or y = x/z

(x, 7) and (-7, 4); slope: 1
Answer: x= -4
Step-by-step explanation: slope = (y2-y1)/(x2-x1).
(4-7)/(-7-x)
-3/-7-x=1
Multiply both sides by -7-x
-3=-7-x
Add 7 to both sides
4=-x so x = -4

2.7z + 1.2z - 6.5 = 0.7
Answer:
= 1 . 8 4 6 1 5 3 8 4 6
Step-by-step explanation:
I took the test yesterday and I got a 100 on the math part
Answer/Step-by-step explanation:
Combine multiplied terms into a single fraction
2.7z+1.2z−6.5=0.7
2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7
Combine multiplied terms into a single fraction
2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7
2 7 /1 0 + 6 5 − 6 . 5= 0 . 7
Find common denominator
2 7 /1 0 + 6 5 − 6 . 5= 0 . 7
[tex]\frac{27z}{10} +\frac{2.6z}{10} +\frac{10(-6.5)}{10} =0.7[/tex]
Combine fractions with common denominator
[tex]\frac{27z+2*6z+10(-6.5)}{10} =0.7[/tex]
Multiply the numbers
[tex]\frac{27z+12z-65}{10} =0.7[/tex]
Combine like terms
[tex]\frac{39z-65}{10} =0.7[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]10*\frac{39z-65}{10} =10*0.7[/tex]
Cancel multiplied terms that are in the denominator
39z-65=10*0.7
Multiply the numbers
39z-65=7
Add 65 to both sides of the equation
39z-65+65=7+65
Simplify
39z=72
Divide both sides of the equation by the same term
[tex]\frac{39z}{39} =\frac{72}{39}[/tex]

six times the difference of a number and three is -42 (write and equation and solve)
Here's ur perfect answer
Hello!
6(3-x)=-42
Use the Distributive Property:
18-6x=-42
-6x=-42-18 (move all the constants (numbers) to the right side, using the opposite operation)
-6x=-60
6x=60
Divide both sides by 6:
x=10

How do you solve Y+4= -3 (x-2)
Answer:
This problem is in Point Slope form:
To turn it to Slope-Intercept form, you must follow these simple steps below⤵⤵⤵:
Distribute -3 among everything inside the parenthesis to get y + 4 = -3x + 6.Subtract 4 from 6 to get y = -3x + 2.To turn it to Standard Form, you must follow these simple steps below⤵⤵⤵:
Use the Slope-Intercept form of this equation, in order to convert it.Add 3x on both sides of the equal sign, to get 3x + y = 2.Hope this helps you :)

parallel perpendicular or neither
Answer:
Parallel
Step-by-step explanation:
Line A can be simplified to 1/5x = y.
Line B can be simplified to y = 1/5x + 16.
They both have the same slope, 1/5, so they will be parallel.
Answer:
Parallel
Step-by-step explanation:
Same thing as the last one. Put it in [tex]y=mx+b[/tex]
A: [tex]y=1/5x[/tex]
and
B: [tex]y=1/5x+16[/tex]
These lines are parallel because they have the same slopes, but different y-intercepts.
