all integers less than -6
Answer: -7, -8, -9, and so on
Step-by-step explanation:
if you graph the line x=-6 what type of slope would it have?
A.Positive
B. Negative
C.Zero
D. undefined
Answer:
undefined
Step-by-step explanation:
x=-6 is a vertical line at x=-6.
Any vertical line has an undefined slope.
Let's pick two points on x=-6– (-6,1) and (-6,0)
(1-0)/(-6-(-6))=1/-6+6=1/0
Because you cannot divide by 0, a vetical line has an undefined slope.
The lines shown below are parallel. If the green line has a slope of -2, what is the slope of the red line?
Answer:
-2
Step-by-step explanation:
if lines are parallel then they always have the same slope!

can the following side lengths form a triangle?
Answer:
no
Step-by-step explanation:
The triangle inequality requires the sum of the shorter two sides exceed the length of the longest one. Here, we have ...
10 +12 = 22 . . . . does not exceed 22
The lengths will not form a triangle.
_____
Additional comment
Some authors write the triangle inequality as ...
a +b ≥ c
If this is the one your curriculum author uses, then these side lengths will form a triangle.
This graph represents a linear function.
Which equation is represented by this graph?
Answer:
Answer is A
Step-by-step explanation:
» Consider two points plotted on the line;
(3, 0) and (0, -2)» General equation of a line has an expression in format of;
[tex]{ \rm{y = mx + c}}[/tex]
m is the slopec is the y-intercept» Finding the slope [m] :
[tex]{ \rm{slope = \frac{y_{2} - y _{1}}{x _{2} - x _{1} } }} \\ [/tex]
• But remember from the points or coordinates we fetched out of the graph;
[tex] { \tt{y_{2} = - 2}} \: \mid \: { \tt{y_{1} = 0}} \\ { \tt{x_{2} =0 }} \: \mid \: { \tt{x_{1} = 3}}[/tex]Therefore, lets feed in the formular:
[tex]{ \tt{m = \frac{ {}^{ - } 2 - 0}{0 - 3} = \frac{ - 2}{ - 3} }} \\ \\ { \boxed{ \tt{m = \frac{2}{3} }}}[/tex]
» Finding y-intercept [c] :
☑ REMEMBER: y = mx + c
• Consider point (0, -2)
[tex]{ \tt{y = mx + c}} \\ { \tt{ - 2 = ( \frac{2}{3} \times 0) + c}} \\ \\ { \boxed{ \tt{ \: c = - 2 \: }}}[/tex]
» Arrange the equation:
Equation is y = ⅔x - 2
The equation of the linear function in the given graph, in slope-intercept form, is: A. y = 2/3x - 2
What is the Equation of a Linear Function?The equation of a linear function can be defined by the equation, in slope-intercept form, as y = mx = b.
slope = my-intercept = bSlope (m) = rise/run = 2 units/3 units = 2/3
Y-intercept (b) = -2
Substitute b = -2 and m = 2/3 into y = mx + b.
y = 2/3x + (-2)
y = 2/3x - 2 (Option A)

All sides of a square are the same length. The area is two of the sides multiplied together. Thus, (3x+2) must be the length of a side (all sides, actually)

Subtract 3x—y—z from the sum of 3x—y + z and 2x–y —z. what is the the
coefficient of x in the result?
with step pls
Answer:
the coefficient of x is 2
Step-by-step explanation:
(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)
Apply the distributive law: - (a - b) = -a + b
Therefore, - (3x - y - z) = -3x + y + z
So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z
Collect like terms: = 3x + 2x - 3x - y - y + y + z - z + z
Combine like terms: = 2x - y + z
Therefore, the coefficient of x is 2
Therefore, the coefficient of x is 2

Use the Binomial Theorem to expand the binomial
(d + 5b)3
Answer:
[tex]\displaystyle{(d+5b)^3 = d^3 + 15bd^2 + 75b^2d + 125b^3}[/tex]
Step-by-step explanation:
The Binomial Theorem states that:
[tex]\displaystyle{(x+y)^n = \binom{n}{0}x^ny^0 + \binom{n}{1}x^{n-1}y^1+\binom{n}{2}x^{n-2}y^2 + \dots + \binom{n}{n}x^{n-n}y^n}[/tex]
Note that:
[tex]\displaystyle{_n C _r = \binom{n}{r} = \dfrac{_n P _r}{r!} = \dfrac{n!}{(n-r)!r!}}[/tex]
Therefore, first, we will write the expansion:
[tex]\displaystyle{(d+5b)^3 = \binom{3}{0}d^3(5b)^0 + \binom{3}{1}d^2(5b)^1+\binom{3}{2}d^1(5b)^2 + \binom{3}{3}d^0(5b)^3}[/tex]
Evaluate each terms:
[tex]\displaystyle{(d+5b)^3=\dfrac{3!}{3!0!}d^3 + \dfrac{3!}{2!1!}d^25b+\dfrac{3!}{1!2!}25b^2d + \dfrac{3!}{0!3!}125b^3}\\\\\displaystyle{(d+5b)^3 = d^3 + 15bd^2 + 75b^2d + 125b^3}[/tex]
Henceforth, [tex]\displaystyle{(d+5b)^3 = d^3 + 15bd^2 + 75b^2d + 125b^3}[/tex] is the expansion.

Step-by-step explanation:
1/6 can also be represented as 2/12
Sisters: 2/12
Kayla's: 7/12
7/12 - 2/12 = 5/12
Answer:
5/12 inches taller!
Step-by-step explanation:
Kayla: 7/12 foot tall, and Sister: 2/12 or 1/6 of a foot tall.
No, not the people but the sandcastles. Take 2/12 from 7/12 and you get 5/12.

y=s when x=3, find when x=12
Answer:
y = s * 4
Step-by-step explanation:
You multiplied 4 to 3 to obtain 12:
x = 3 ; x = 3 * 4 ; x = 12
Therefore, if you multiply 4 to x, you must do the same to the other:
y = s
y = s * 4 is your answer.

y = 1 over 3.x − 1
y = 3x − 1
y = 3x + 1
Answer:
y = 3x - 1
Explanation:
1)
passes y-axis means x will be 0,
when x = 0,
y = 3x − 1
y = 3(0)-1
y = -1 ................so matches with option 1.
2)
Here given in second option passes through ( 1 , 2 )
if x = 1
y = 3x − 1
y = 3(1) − 1
y = 2 ..........................so matches with option 2.
Therefore equation: y = 3x - 1 represents the current following.
Answer:
y = 3x - 1

*brainliest will be given if you answer both part A and B ;) *
** NO LINKS ALLOWED, IF I SEE ANY I WILL REPORT YOU!**
Answer:
Step-by-step explanation:
Given:
1cm = 85 km (on the map)
so map is
14 x 14 long or 85 x 85
Part A:
since the map is 14cm long, and the river is also 14 cm long, and each centimeter is equal to 85km, that means, =
14 x 85 = 1190km
so the river is 1190km long
Part B:
we can use just convert 765 into map cm to get answer,
sooo
765/85 = 9cm
