Find an equation for the line with slope m through the point (a,c).
The equation of a line with a given slope and passing through a point can be found using the point-slope formula.
To find the equation of a line with a given slope (m) passing through a point (a, c), we can use the point-slope formula. The point-slope formula is given by:
y - c = m(x - a)
where (x, y) represents any point on the line. This equation represents a line with slope m passing through the point (a, c).

Carly has 2 more nickles than dimes in her pocket She has 40 cents How many nickels does carly have ? how many dimes does carly have?
Carly has 2 dimes and 4 nickels in her pocket.
Explanation:Let's assume Carly has x dimes in her pocket. Since Carly has 2 more nickels than dimes, she would have x + 2 nickels. The value of x dimes is 10x cents and the value of (x + 2) nickels is 5(x + 2) cents. Since Carly has 40 cents in total, we can set up the equation: 10x + 5(x + 2) = 40.
Simplifying the equation gives us: 10x + 5x + 10 = 40. Combining like terms gives us: 15x + 10 = 40. Subtracting 10 from both sides gives us: 15x = 30. Dividing both sides by 15 gives us:
x = 2.
Therefore, Carly has 2 dimes and 4 nickels.

What is the coefficient of the x9y-term in the binomial expansion of (2y + 4x3)4? 4 32 128 512
Answer:- 512
Explanation:-
We know that [tex](m+1)^{th},\ (T_{m+1})[/tex] in the binomial expansion [tex](p+q)^n[/tex] is given by
[tex]T_{m+1}=^nC_m\ p^{n-m}q^m[/tex]
Assume that [tex]x^9y[/tex] occurs in the [tex](m+1)^{th}[/tex] term of the expansion of [tex](2y+4x^3)^4=(4x^3+2y)^4[/tex]
[tex]T_{m+1}=^4C_m\ (4x^3)^{4-m}(2y)^m[/tex]
Comparing power of x and y in [tex]x^9y[/tex] we get m=1
Thus term for m=1 [tex]=\ ^4C_1\ (4x^3)^{3}(2y)^1=^4C_1=\frac{4!}{(4-1)!1!}(64x^9)(2y)=4(128x^9y)=512x^9y[/tex]
Thus the coefficient of [tex]x^9y[/tex] is 512.
What percent of 86 is 50 to the nearest whole percent
Answer:
58%
Step-by-step explanation:
Let us suppose x percent of 86 is 50.
Therefore, we have the below equation
x% of 86 = 50
Eliminating percentage, we get
0.0x × 86 = 50
Solve for x
[tex]0.0x\times86=50\\\\0.0x=\frac{50}{86}\\\\x=\frac{50}{86}\times100\\\\x=58.1[/tex]
Hence, in nearest whole percent, we have
x = 58%
Therefore, 58% of 86 is 50

x = 14/5 = 2.8
x = 2.8 which isn't a choice.
Answer:
The answer is B 1/20
Step-by-step explanation:
The word "Product" means multiplication, and we need to find the value of "x" here's an equation:

What is inequality?In mathematics, an inequality is a relation that makes a non-equal assessment between two numbers or different mathematical expressions. Its miles are used most often to evaluate numbers at the quantity line by means of their size. There are several unique notations used to represent exceptional types of inequalities:
The notation a < b means that a is less than b.
The notation a > b approach that a is greater than b.
The range of y which will satisfy this inequality will result in the first fraction of a larger value as compared to the second fraction.
Multiplying both sides of an inequality by 12, we get:
12×10>12×3y-7/12
2(7-2y)>3y-7
14-4y3y-7
14+7>3y+4y
21> 7y

The sign of the product of two integers with the same sign is positive. What is the sign of three integers with the same sign? Explain your thinking.
Answer:
Negative.
Step-by-step explanation:
The answer is negative, because if the number of integers you are multiplying is odd, then the sign is negative. But if the number of integers you are multiplying is even, then the sign is negative. In this case, three is odd, so the sign is negative.
Which equation can be used to find one or more factors of 26
The factors of 26 are one, two, 13 and 26. One and the number itself, in this case 26, are always factors. Since 26 is an even number, which means that it ends in zero, two, four, six or eight, it's evenly divisible by two. Two times 13 equals 26.
No numbers between two and 13 divide evenly into 26, so there are no more factors other than the four listed. Because two and 13 are both prime numbers, which are numbers that are only divisible by one and themselves, the prime factorization of 26 is 2 x 13. The prime factorization of a number refers to the prime numbers that multiply together to make that given numberCan rational numbers be expressed as a fraction of two integers

Josh is 4 years older than Delaney. In 5 years the sum of their ages will be 60. How old is Josh now?
Final answer:
The problem is a middle school mathematics question about algebra and age. By setting up an equation and solving it, we found that Josh is currently 27 years old.
Explanation:
The subject of this question is Mathematics, and it is likely a Middle School level problem. To solve this, we set up an equation based on the information provided: Let's denote Delaney's current age as D. According to the question, Josh is 4 years older than Delaney, so Josh's current age is D + 4 years. In 5 years, Delaney will be D + 5 years old, and Josh will be (D + 4) + 5 which simplifies to D + 9 years old. We know that the sum of their ages in 5 years will be 60. Therefore, the equation is:
D + 5 + D + 9 = 60
Combining like terms, we get:
2D + 14 = 60
Subtracting 14 from both sides, we get:
2D = 46
Divide both sides by 2 to find Delaney's current age:
D = 23
Now, we can determine Josh's current age by adding 4:
Josh's age = D + 4 = 23 + 4 = 27
Therefore, Josh is currently 27 years old.

The temperature at midnight was 25 degrees.
We have at one winter night the temperature fell 16 degrees between midnight and 5 A.M. By 9 A.M. the temperature had doubled from what it was at 5 A.M. By noon, it had risen another 12 degrees to 30 degrees.
We have to determine the temperature at midnight?
What is Temperature ?Degree of hotness or coldness measured on a definite scale is called Temperature. When the temperature of the body is high it is called hot body and when it is low it is called cold body.
According to the question -
Assume the temperature at mid - night be x and at 5 AM be y.
Then -
x - y = 16
At 9 A.M. , assume the temperature to be z. Then -
z = 2y
At Noon -
z + 12 = 30
z = 30 - 12
z = 18 degree
At 9 A.M., we have -
z = 2y
18 = 2y
y = 9 degrees
At mid - night, we have -
x - y = 16
x - 9 = 16
x = 25 degrees
Hence, the temperature at midnight was 25 degrees.

Peyton is altering her new jacket to enter it into the Bodacious Bedazzling Contest. In order for a garment to be considered "bedazzled," it must contain an amount of gems that fall within the range of the following inequality 132 ≤ ½x + 8 ≤ 193. Find the range of gems Peyton must use to enter he jacket in the contest.
Answer:
the range will be 248 ≤ x ≤ 370
Step-by-step explanation:
The given inequality models the range of amount of gems.
132 ≤ 1/2x + 8 ≤ 193
So we have to solve the inequality for the value of x.
132 ≤ [tex]\frac{1}{2}x[/tex] + 8 ≤ 193
Now we subtract 8 from the inequality.
132 - 8 ≤ ([tex]\frac{1}{2}x[/tex] + 8) - 8 ≤ 193 - 8
124 ≤ [tex]\frac{x}{2}[/tex] ≤ 185
Now we multiply the inequality by 2
124 × 2 ≤ [tex](\frac{x}{2})[/tex] × 2 ≤ 185 × 2
248 ≤ x ≤ 370
So the range will be 248 ≤ x ≤ 370
