Write an equation in point-slope form of the line that passes through (2,7) and has the slope m=4
Answer: y-7=4(x-2)
Step-by-step explanation:
Point-slope form is y-y₁=m(x-x₁). Since we are given the point and slope, we can directly plug them in.
y-7=4(x-2)
Now, we know that y-7=4(x-2) is the equation.

Find the LCM of 9,25,36 and 73 ?
Step-by-step explanation:
9 = 9 , 25 = 5 , 36 = 36
if it's helpful please tell me
Answer: The least common multiple is 65700
Step-by-step explanation:
To begin, find the prime factors of the given numbers, (and you find they have very little in common.)
9=3×3 25=5×5 36=2×2×3×3 73= 73×1 (73 is a prime number)
Only the 3's of 36 overlap with the 3's of 9
To find the LCM you must multiply all the prime factors that don't overlap:
3×3×5×5×2×2×73
If the 73 is changed to 72, the LCM is a somewhat lower number: 1800.
To test these LCM's try dividing by any of the factors or numbers given.
If the quotient is not a whole number, the LCM doesn't include that factor.
put the following numbers in order from smallest to largest

2x+y=7 for y neeedd help
Answer:
y = -2x + 7Step-by-step explanation:
Solve for y:
2x + y = 7Add - 2x to both sides
2x + y - 2x = 7 - 2xy = 7 - 2xor
y = -2x + 7Give the domain and range of each relation. Tell whether the relation is a function. Explain.
A rectangle has a length 5 meters more than five times the
width. The area of the rectangle is less than 100 meters
squared. Write an expression that represents all possible
widths (use the variable x) of the rectangle. Write your answer
as an inequality, a
Given:
A rectangle has a length 5 meters more than five times the width.
The area of the rectangle is less than 100 meters squared.
To find:
The expression or inequality that represents all possible widths of the rectangle.
Solution:
Let x be the width of the rectangle.
Length of the rectangle is 5 meters more than five times the width.
[tex]length=5x+5[/tex]
Area of rectangle is
[tex]Area=length \times width[/tex]
[tex]Area=(5x+5) \times x[/tex]
[tex]Area=5x^2+5x[/tex]
The area of the rectangle is less than 100 meters squared.
[tex]5x^2+5x<100[/tex]
[tex]5x^2+5x-100<0[/tex]
Divide both sides by 5.
[tex]x^2+x-20<0[/tex]
[tex]x^2+5x-4x-20<0[/tex]
[tex]x(x+5)-4(x+5)<0[/tex]
[tex](x+5)(x-4)<0[/tex]
It is true if one factor is negative and other is positive. So,
[tex]x-4<0\Rightarrow x<4[/tex] ...(i)
[tex]x+5>0\Rightarrow x>-5[/tex] ...(ii)
Using (i) and (ii), we get
[tex]-5<x<4[/tex]
Therefore, the required expression or inequality for possible
widths of the rectangle is [tex]-5<x<4[/tex].
This afternoon, Sara noticed that the number of the page assigned for homework is divisible by both 12
and 2. What is the smallest possible page number that could have been assigned?
Answer:
12

How do you find the equivalent ratios
Answer:
by multiplying or dividing
Step-by-step explanation:
Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.

y’all please help asap
Answer:
b=−ax+4a+3x
a= b−3x −x+4
Step-by-step explanation:
The values of a and b make the solution of the equation x = -5 are 1 and -6
How to determine the values of a and b?The equation is given as:
a(4-x) = -3x+b
When x = -5, we have:
a(4+5) = -3(-5)+b
Evaluate the products
9a = 15 + b
Set a = 1
9(1) = 15 + b
Make b the subject
b = 9 - 15
b = -6
Hence, the values of a and b make the solution of the equation x = -5 are 1 and -6

How do you do this question?
Answer:
Diverges
Step-by-step explanation:
The order of the numerator (2) is greater than the order of the denominator (1). So the sequence will diverge as n approaches infinity.
5b.) Use this equation to write the area A in terms of the perimeter p.

Answer:
(1, -5)
Step-by-step explanation:
Here, it is easy to check the offered choices. We find the first one works, so our check is short.
For (x, y) = (1, -5)
3·1 +10·(-5) = 3 -50 = -47 . . . yes
5·1 -7·(-5) = 5 +35 = 40 . . . yes
__
Both of the intercepts in the first equation are negative, so the line will form a triangle with the axes in the 3rd quadrant. The intercepts for the second equation are negative for y and positive for x, so the line forms a triangle with the axes in the 4th quadrant. The y-intercept for the first equation is -4.7; for the second equation, it is -40/7 = -5 5/7. This means the lines must cross in the 4th quadrant.
The only offered point in the 4th quadrant is (1, -5).

A. The Clear-Picture Cable Company charges different rates for ordering different levels of cable service. Clear-Picture Cable Company charges $24.95 a month for basic cable services plus $6.95 a month for each additional premium channel. If Stacey's monthly bill is $45.80, how many premium channels is she receiving? Write and solve and equation to answer the question. Show all work.
B. Dan signed a contract for 12 months of basic cable service with 2 premium channels each month. Dan budgeted $400 for this year's cable expenses. EXPLAIN whether Dan budgeted enough money to cover the yearly cost for his cable contract.
(please answer with all work and a full explanation for B. THANKS SO MUCH!!)
Answer:
A. 3 premium channels
B. No, he did not
Step-by-step explanation:
1a. make an equation that shows the price Stacey has to pay each month. x is how many premium channels she's paying for.
24.95 + 6.95x = 45.8
2a. subtract 24.95 from both sides.
6.95x = 20.85
3a. divide both sides by 6.95.
x = 3
1b. make an expression to show the price of Dan's contract. (keep in mind, he has to pay for 2 premium channels for 12 months, so you would have to pay for the premium channels 24 times!)
24.95(12) + 6.95(24)
2b. multiply.
299.4 + 166.8
3b. add.
$466.20
Dan would have to pay $466.20, so no, he did not budget enough money.
