Which coordinate does not belong to the equations y = 2x + 5 or x = -3?
O (-3,7)
O (-3,1)
O (1,7)
O (0,-5)
O (-3,-1)
Answer:
O✓ (0,-5)
Step-by-step explanation:
Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

slope = (y2-y1)/(x2-x1)
the first slope is 0 (horizontal line)
second slope is undefined (vertical line)
Find the slope of the line passing through the points and .
Answer:
slope = "rise over run" (the change in y coordinates divided by the change in x coordinates) =
(8--7)/(3-7) = 15/-4 = -15/4
Hope it helps mark as brainliest
Answer:
slope = - [tex]\frac{15}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 8 ) and (x₂, y₂ ) = (7, - 7 )
m = [tex]\frac{-7-8}{7-3}[/tex] = [tex]\frac{-15}{4}[/tex] = - [tex]\frac{15}{4}[/tex]

jada and priya are trying to solve the equation 2/3 + x = 4 •Jada says, “i think we should multiply each side by 3/2 because that is the reciprocal of 2/3 •Priya says, “I think we should add -2/3 to each side because that is the opposite of 2/3” a. which person’s strategy should they use? why? b.write an equation that can be solved using the other person’s strategy.
Answer:
Priya is correct.
Because 2/3 is being added to x and not multiplied, then subtracting 2/3 from both sides is the correct action.
Step-by-step explanation:
Let's run through solving it that way:2/3 + x = 4
2/3 - 2/3 + x = 4 - 2/3
0 + x = 4 - 2/3
x = 4 - 2/3
x = 10/3
Pleease Mark brainliest
Answer:
Priya is correct because we want the opposite of positive 2/3 and while substituting please check if they are multiplying with x or adding with x. in this case they added up with x so we'll subtract in the other side.
Step-by-step explanation:
Can someone check to see if im doing this correct? Thanks!!! Look at pic
Write the equation of the line that passes
through the points (3, 1) and (-2, 6).
Answer:
Equation is Y=mx+c (that's how I know it, it may differ)
Step-by-step explanation:
First get the slope which is M and you just gotta do the second y - the first y from the brackets and divide them by the second x - the first x
6-1 /-2-3 = 5/-5
= -1
So now u gotta find c, C= Y-mx
And u have got two brackets, which have an x and y, and u now have m.
Pick one of the brackets like (-2,6) and put them in the equation so it will be : C =6+1*-2
So C =4
The equation now is : Y = - 1x + 4

A farmer is digging a ditch across his field.
Each day he digsmile of the ditch.
Which model represents the total length in miles the farmer digs in 8 days?
Answer:
Let us consider that ,
The worker can complete the work in x hours .
So, he can complete 1/x part of work in 1 hour.
Now, The workers does 2/3 of what he does. So they do 2/3(1/x) part of work in 1 hour . 2/3x work in 1 hour .
Consider them all working together,
So work done in one hour, = 1/x + 2/3x + 2/3x = 3 + 4 / 3x = 7/3x .
So, They taken 1 hour to complete 7/3th part of work. So, In 3x/7 hours , They all can complete the work.
Ratio of the time taken by all instead of only one = 3x/7 : x = 3/7 .
So ,The required option is 3/7

what is the next term in the geometric sequence?
4/9,-4/3,4,...
Answer:
-12
Step-by-step explanation:
r = -3
4/9 * (-3) = -4/3
-4/3 * (-3) = 4
so, 4 * (-3) = -12
Answer:
-12
Step-by-step explanation:
in this geometric sequence we can see that each term is multiplied by -3 times the term before it see 4/9 x-3 = -4/3 x-3 = 4 hence the answer is -12 sorry if the explanation wasn’t good or up to ur guys standards im just a kid not some expert anyway i hope this helps :D Have a Great day!!!!

6 buckets of cements is needed to be mixed with sand to produce 24 buckets.
RatioRatio is used to show the quantitative relation between two amounts. Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.
The ratio is 1:3, hence for 24 buckets:
Number of cement = (1 / (1 + 3)) * 24 = 6 buckets
6 buckets of cements is needed to be mixed with sand to produce 24 buckets.

Answer the question below using the following amortization table.
What is the regular monthly payment?
O $352.15
O $703.01
O $1758.17
O $1055.16
Answer: $1,758.17
Adding the principal paid and interest paid will result in $1,758.17 for every month/column.
For example,
Month 21 - $688.68 + $1,069.49 = $1,758.17
Month 22 - $692.73 + $1, 065.44 = $1,758.17
And so on..
As $1,758.17 is the constant total when you add principal paid and interest paid in every month, that is your answer.

6t-3=21 solve the two setp equation and show your work and check the soultion
Answer:
t=4
Step-by-step explanation:
6t-3=21
6t=21+3
t=24/6
t=4
Checking,
6t-3=21
6*4-3=21
24-3=21
21=21
True.
Answer:
t = 4
Step-by-step explanation:
1. Group all constants on the right side of the equation
6t-3=21
Add 3 to both sides:
6t-3+3=21+3
Simplify the arithmetic:
6t=21+3
Simplify the arithmetic again:
6t=24
2. Isolate the t
Divide both sides by 6:
[tex]\frac{6t}{6}=\frac{24}{6}\\ \\[/tex]
Simplify the fraction:
[tex]t=\frac{24}{6}[/tex]
Find the greatest common factor of the numerator and denominator:
[tex]t=\frac{4\cdot6}{1\cdot6}[/tex]
Factor out and cancel the greatest common factor:
t=4
