Answer:
y = -5x-19
Step-by-step explanation:
Use the point-slope formula to plug in the x1 and y1 and the slope -5 to get the equation y = -5x-19.
Formula: y-y1 = m(x-x1)
m = slope
x1 = x-value
y1 = y-value
Answer:
y=-5x-15
Step-by-step explanation:
starts off in point-slope form:
y+4=-5(x+3)
distribute the 5:
y+4=-5x-15
subtract 4 from each side:
y=-5x-20
^that answer is in slope intercept form.

In the equation 6x - 2 = -4x + 2, Spencer claims that the
first step is to add 4x to both sides. Jeremiah claims that
the first step is to subtract 6x from both sides. Who is
correct? Explain.
Answer:
Spencer is correct
Step-by-step explanation:
Because adding 4x to each side will bring both numbers to a positive and that makes it easier to get the answer
Answer:
Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.

The sum of 4 times a number and 7 equals 5.
Use the variable w for the unknown number.
Answer:
4w +7 = 5
Step-by-step explanation:
Have a nice day.
Answer:
4w + 7 = 5
Step-by-step explanation:
"sum" means addition (+), so we're to add two items:
item 1 to be added
"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).
Therefore, 4 x w = 4w
item 2 to be added
This is the number 7
The sum
4w + 7
Now, the sum, equals(=) the number 5, therefore answer:
4w + 7 = 5

A television set can be purchased with a $200 down payment plus a $39.99 monthly payment. Alternatively, the television can be purchased with no money down and monthly payments of $59.99. Solve for the number of months until the payments are of equal value.
Answer:
10 months
Step-by-step explanation:
Let x denotes number of months.
Down payment of first TV = $200
Per month payment of first TV = $39.99
Total payment of first TV [tex]=200+39.99x[/tex]
Down payment of second TV = $0
Per month payment of second TV = $59.99
Total payment of second TV [tex]=0+59.99x=59.99x[/tex]
To find number of months until the payments are of equal value,
solve [tex]200+39.99x=59.99x[/tex]
[tex]200+39.99x=59.99x\\200=59.99x-39.99x\\200=20x\\x=\frac{200}{20}\\ x=10[/tex]
So, payments become of equal value after 10 months.

-2m + 7 < 13 or 5m + 12 > 37
Need help.!!
Answer:
m<-3 or m>5
Step-by-step explanation:
-2m+7<13
-2m<6
m<-3
5m+12>37
5m>25
m>5
The solution of the two expressions will be m<-3 or m>5.
When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Given that the two inequalities are -2m + 7 < 13 or 5m + 12 > 37. The inequalities will be solved as,
-2m+7<13
-2m<6
m<-3
5m+12>37
5m>25
m>5
Hence, the solution for the inequalities will be m<-3 or m>5.

You had 23 dollars to spend on 4 avocados. They were very green. After buying them you had 11 dollars. How much did each avocado cost?
Answer:
the avacodos cost 12
Step-by-step explanation: if you sutract 23 by 11 you get 12 and if you chek you ansewer by adding 12+11=23
The answer is $3.
Step-by-step explanation:
1. Let's subtract 11 ($ remaining) from 23 ($ we had originally) to see how much we spent in total. (23 - 11 = 12)
2. Divide 12 ($ spent) and 4 (Avocados bought) to find out how much each avocado cost. (12 ÷ 4 = 3)
Find the slope of (1,8) and (3,12) ?
Answer:
The slope is 2.
Step-by-step explanation:
Slope formula is rise/run. So in other words, it is y2-y1/x2-x1. In this case it would be 12-8/3-1. That equals 4/2. You need to simplify that by dividing both 4 and 2 by 2. So, that gives you 2/1. Whenever you have a number over 1 that is the same as saying just the numerator. So the slope would be 2.

There are 24 calories in a candy bar. How many calories are there in 33 candy bars ?
Answer: 406
Step-by-step explanation:
Answer:
792
Step-by-step explanation:
The answer is 792 because, we know that there is 24 calories in each bar, so, when calculating total amount of, you wan to multiply that amount by however many bars there are. The reason you multiply is because(using this example) when you have a bar with 24 calories and another bar with the same amount, you just add the two calorie amounts together, or 24 + 24. Since you have 33 bars, you would do that 33 times, which is the same as 24 x 33. So if you calculate 24 x 33, you get 792. Another way to solve this is you can use the formula x=cb where x is the total amount of calories, c is the number of calories in one bar, and b is how many bars you have.

A side of the triangle below has been extended to form an exterior angle of 164º. Find the value of x.
Answer:
x=50
Step-by-step explanation:
The value of the angle of the triangle 'x' will be 111°.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The sum of the two interior angles of the triangle is equal to the exterior angle of the triangle.
x + 53° = 164°
Simplify the equation, then we have
x + 53° = 164°
x = 164° - 53°
x = 111°
The value of the angle of the triangle 'x' will be 111°.

a migrating bird flies 468 miles in 13 hours. how many miles does it fly in 3 hours?
Answer:
The answer is 108mi
Step-by-step explanation:
to solve this problem, we need to write a ratio.
[tex]\frac{468mi}{13hrs}[/tex]
to solve for 3 hours, we need to figure out how many miles the bird can fly in 1 hour. to do that, we need to divide the numerator and denominator by 13.
[tex]\frac{36mi}{1hr}[/tex]
now we have a unit rate that represents distance covered per hour.
to solve for 3, we need to multiply the numerator and denominator by 3.
[tex]\frac{108mi}{3hrs}[/tex]
the question is asking for miles. therefore, the bird can fly 108mi in 3 hrs.
hope this helps!
Answer:
108 miles
Step-by-step explanation:
For this problem you can create a proportion:
[tex]\frac{468 miles}{13 hours}[/tex]
To find how many miles it flies in 3 hours, we need to find the unit fraction. Do this by making the denominator (bottom number) 1:
here, we must divide by 13:
[tex]\frac{468 miles}{13 hours}[/tex]÷[tex]\frac{13}{13}[/tex]= [tex]\frac{36 miles}{1 hour}[/tex]
Each hour, they fly 36 miles.
To find how many miles they fly in 3 hours, make a proportion:
[tex]\frac{36 miles}{1 hour}[/tex]=[tex]\frac{x miles}{3 hours}[/tex]
Then, solve:
use cross multiplication:
36·3=108
x·1=x
108=x
identify the sequence 18,13,8,3,-2 PLZ HELPPPPP
The common difference between each term is -5. The nth term of the sequence as follows: aₙ = 18 - 5(n-1)
The given sequence is 18, 13, 8, 3, -2.
To identify the pattern in the sequence, we can observe that each term is decreasing by 5. Starting from 18, we subtract 5 to get the next term, and so on. The common difference between each term is -5.
Using this pattern, we can continue the sequence as follows:
-2 - 5 = -7
-7 - 5 = -12
-12 - 5 = -17
-17 - 5 = -22
The extended sequence would be -2, -7, -12, -17, -22.
In terms of the general formula, we can represent the nth term of the sequence as follows:
aₙ = 18 - 5(n-1)
