Write the following inequality in slope-intercept form.
10x + y > -1
Write your answer with y first, followed by an inequality symbol. Use integers, proper
fractions, and improper fractions in simplest form.
Answer:
y > - 10x - 1
Step-by-step explanation:
Given
10x + y > - 1 ( subtract 10x from both sides )
y > - 10x - 1 ← in slope- intercept form
Answer:
y > -10x - 1.
Step-by-step explanation:
10x + y > - 1
Subtract 10x from both sides:
y > -10x - 1.
Solve the equation below.
3/2x - 2.2 = 2(0.7x - 1)
Answer:
x = 2
Step-by-step explanation:
3/2x - 2.2 = 2(0.7x - 1)
3/2x - 2.2 = 1.4x - 2
0.1x - 2.2 = -2
0.1x = 0.2
x = 2

This graph is an example of
A. a linear function
B. a nonlinear function
C. neither a linear nor nonlinear function - it is not a
function at all
will give brainiest if correct
Answer:
C Neither.
Step-by-step explanation:
Its not linear because it is a curve.
Its not a function because it fails the vertical line test:
- we can draw a vertical line which passes through 2 points on the graph.
Mangoes cost $4 each and nectarines cost $2 each. Dominic buys m mangoes and n nectarines for $32.
Fill in the missing values to write an equation for the information given.
Answer: 6m+4n=32
Step-by-step explanation:
m=4
n=2
From this, we can deduce that m+n=32.
6*4=24 and 4*2=8. 24+8=32
So, 6m+4n=32. Hope this was what you were looking for!
The product 2+bi)(3+2i) is equal to 13i. What is the value b?
Answer:
[tex]b = 3[/tex]
Step-by-step explanation:
We are given that:
[tex](2 + bi)(3+2i) = 13i[/tex]
And we want to determine the value of b.
First, expand:
[tex]\displaystyle \begin{aligned} (2+bi)(3+2i)&=2(3+2i)+bi(3+2i) \\ &= (6+4i)+(3bi+2bi^2) \\ &= (6+2b(-1))+(4i+3bi) \\ &= (6-2b) + (4+3b)i\end{aligned}[/tex]
Therefore, we can write that:
[tex](6-2b) + (4+3b)i = 0+ 13i[/tex]
If two complex numbers are equivalent, their real and imaginary parts must be equivalent. Hence:
[tex]6-2b = 0 \text{ and } 4+3b = 13[/tex]
Solve for each case:
[tex]b=3 \text{ and } b=3[/tex]
The two solutions are equivalent, hence such a number b exists.
In conclusion, b = 3.
Your house is located at point L. Your friend's house is located at point N.
M is the midpoint of IN. How far do you need to travel to walk home from
your friend's house?
3x
2x+ 2
M
N
Answer: 12 units
Replace "units" with "feet", "meters", etc. if your teacher instructs it.
==============================================================
Explanation:
M is the midpoint, which means segments LM and MN are the same length. This is because M cut LN in half.
So,
LM = MN
3x = 2x+2
3x-2x = 2
x = 2
Use this x value to then say
LM = 3x = 3*2 = 6MN = 2x+2 = 2*2+2 = 4+2 = 6Segments LM and MN are 6 units each.
From that, we know,
LN = LM+MN = 6+6 = 12
The distance from your house to your friends house is 12 units.

Mary lives 1 3/4 miles from school. She rode her bycycle to school and back for 5 days. Which expression shows how to estimate the number of miles she rode?
The expression which represents the number of miles Mary rode in 5 days is 5*(2 + 2).
What is mixed fraction?A fraction represented with its quotient and remainder is a mixed fraction.
What is expression?An expression is a number, a variable, or a combination of numbers and variables and operation symbols.
According to the given question.
Distance between Mary's house and school = [tex]1\frac{3}{4} =\frac{7}{4}[/tex]
Number of days Mary rode her bicycle to school and back = 5
⇒ Distance travelled by Mary in one day = [tex]2(\frac{7}{4} )=\frac{7}{2}[/tex]
Therefore, the expression which represents the number of miles she rode in 5 days = [tex]5(\frac{7}{2} )=\frac{35}{2}=17.5 miles[/tex] ≈ 20 miles
Hence, the expression which represents the number of miles Mary rode in 5 days is [tex]5[/tex] *(2+2).

please help it is midpoint
Answer:
(8.3, 3.15 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (4.6, 2.3) and (x₂, y₂ ) = (12, 4) , then
midpoint = ( [tex]\frac{4.6+12}{2}[/tex] , [tex]\frac{2.3+4}{2}[/tex] ) = ( [tex]\frac{16.6}{2}[/tex] , [tex]\frac{6.3}{2}[/tex] ) = ( 8.3, 3.15 )
Answer:
[tex]mid \: point \: for \: x = \frac{x1 + x2}{2} \\ = \frac{4.6 + 12}{2} \\ x = \frac{16.6}{2} \\ x = 8.3 \\ mid \: point \: of \: y = \frac{y1 + y2}{2} \\ y = \frac{2.3 + 4}{2} \\ \frac{6.3}{2} = 3.15 \\ then(x \: y) = (8.3 \: 3.15) \\ thank \: you[/tex]

Help me solve the following formula for v1
Answer:
v1 = at + v0
Step-by-step explanation:
We want to end up with a formula that looks like v1 = algebraic expression
Start by multiplying both sides of the given formula by t, to eliminate fractions:
at = v1 - v0
Next we isolate v1 by adding v0 to both sides of the above equation:
at + v0 = v1 - v0 + v0, or v1 = at + v0
Answer:
V1=at+V0

Answer:
C
Step-by-step explanation:
It looks impossible to tell if you don't know one simple fact. You have to know that the Plane that contains WTSR and V is opaque which means you can't see through it. So the line that goes through it (containing WQ) is partially not seen.
It is represented by a dashed line that shows the line is there, but it is invisible.
So Q is on the plane, but W is not. W is the answer.
