The second equation with a slope of 1 passing through (1, 4) is y = x + 3

An equation is an expression relating two or more numbers and variables.

The standard form of an equation is:

y = mx + b

Where m is the rate of change(slope) and b is the y intercept.

The first equation:

y = -4x + 8

Both equations intersect at a point with y -coordinate 4. Hence the corresponding x coordinate is by substituting y= 4:

4 = -4x + 8

-4x = -4

x = 1

The point is (1, 4)

The second equation has a slope of 1 and intersect at (1, 4). Hence:

y - 4 = 1(x - 1)

y = x + 3

The second equation is y = x + 3

The correct equation to find the amount, in dollars, x, of check 353 is:

D. 1,460.89 +25.79+ x = 1,536.71

This equation shows that the sum of check 354, check 353, and the known total of 1,460.89 is equal to the corrected total of 1,536.71. So by solving for x, you can find the amount of check 353.

To solve for x, you would subtract 25.79 and 1,460.89 from both sides of the equation:

x = 1,536.71 - 1,460.89 - 25.79

x = 50.03

So the amount of check 353 is $50.03

It is important to notice that option A and B doesn't include the missing check 354, and option C doesn't add the missing check 354 and the corrected total, so option D is the right one.

Seven years ago the sum of their ages was 31:  

               (L - 7) + (M - 7)  =  31

Given that:

Lindsay is 5 years younger than Mark. Seven years ago, the sum of their ages was 31.

let L be Lindsay's age and let m be Mark's age.

​L −7 = (M−7) + 5

⇒ L + M = 31

⇒ ​L = M + 5

⇒ (L−7) + (M−7) = 31

Now,

​L−7 = (M−7) − 5

⇒ L + M = 31

Now, as we know that:

Lindsay is 5 years younger than Mark.

Therefore,

​L = m −5

The value of A when x - 5 is a factor of x³ - 3x² + ax - 10 is -8.

A polynomial factor is a polynomial that divides another polynomial exactly, with no remainder.

For example, if we have a polynomial P(x) = x³ - 3x² + ax - 10, and we have a polynomial factor F(x) = x - 5, we can say that P(x) is divisible by F(x) with no remainder.

In general, a polynomial of degree n has n roots (or zeroes) and the factorization of polynomial can be expressed as a product of its roots and its corresponding multiplicity.

To find the value of A, set x = 5 in the equation x³ - 3x² + ax - 10 and solve for A that will make the equation equal to zero..

So when x = 5, we have:

x³ - 3x² + ax - 10 = 0

(5)³ - 3(5)² + a(5) - 10 = 0

125 - 75 + 5a - 10 = 0

5a = -40

a = -8

Hence, if x - 5 is a factor of x³ - 3x² + ax - 10, then A is equal to -8.

The statement that describes a relationship that has a negative slope: "Greg pays $25 each time he goes rock climbing".

A negative slope indicates that two variables are adversely connected; that is, when x rises, y falls, and when x falls, y rises. A negative slope on a line graph signifies that the line falls as it travels from left to right. For example, when the number of individuals that quit smoking (x) grows, the number of persons developing lung cancer (y) drops. This relationship's graph has a negative slope. Positive slopes are predicated on the fact that when x grows, so does y, hence the change in y/change in x is positive. Negative slopes are based on the fact that when x grows, y decreases, resulting in a negative change in y/positive change in x, yielding a negative response.

The line that has the constant of proportionality between y and x of 1 / 2 , is C. Line C.

The ratio used to compare changes in one variable to those in another is known as the constant of proportionality. The dependent variable fluctuates more with the independent variable when the proportionality constant increases.

The formula for the constant of proportionality is:

= Value of y / Value of x

For Line A we have point ( 1, 7 ) so the constant of proportionality is:

= 7 / 1

= 7

For line B, we have point (2, 3 ) so the constant of proportionality is:

= 3 / 2

Answer:

Step-by-step explanation:

y = x + 8

x + y = 2

using substitution, since y is equal to x + 8 we substitute it for the y in x + y = 2

so we get: x + (x+8) =2

then we simplify, getting 2x + 8 = 2

We make the x on its own on one side of the equation by subtracting 8 on both sides.

2x = -6

divide

x = -3

y = 5

(if x = -3, y = 5 because -3 + 8 =5)

test answer

5 = -3 + 8 works and -3 + 5 = 2 works as well

Answer:

x=18

Step-by-step explanation:

We know that triangle ABC is similar to triangle ADE, so therefore the proportions of their corresponding sides must be congruent.

We know that all of AD is 15 and BD is 5, which leaves AB to be equal to 10.

Next, we set up the following proportion: 10/12 = 15/x because they are corresponding sides of similar triangles divided by eachother.

Cross multiply and you will get 10x = 12x15 (180)

next, divide both sides by 10 to isolate x

x = 18

The situation regarding the experimental probability is described as follows:

The probability that she makes a shot is of 62.5% = 5/8. Use whole numbers from 1 to 8, with 1-5 representing shots that she makes, and 6-8 representing the shots that she misses. For each trial, generate 10 random numbers. Count the number of trials in which the numbers 1 - 5 appears 3 or more times. Divide the number of trials in which she made at least 3 shots by the total number of trials.

A probability is calculated as the division of the number of desired outcomes by the number of total outcomes.

The theoretical probability of making a shot in this problem is given as follows:

62.5%.

The equivalent fraction is given as follows:

Answer:

The exponential form of 5184 is 5184

In simple words, the exponents can said to be the powers of the base. For example, in 2³, the exponent will be 3. If a number is given without any power then its power is 5184. The exponential form is simply the number with exponents.

The polynomial 3x³ 2x² +3 can be written as 3x³ + 2x² + 3. In order to get the polynomial 3x² + 4, we need to add a polynomial which is equal to -3x³ + 5x² + 1.

Therefore, the correct answer is (3) - 3x3 + 5x2 +1.

We can confirm this by performing the following calculation:

3x³ + 2x² + 3 + (-3x³ + 5x² + 1) = 3x² + 4

3x³ + (-3x³) = 0

2x² + 5x² = 7x²

3 + 1 = 4

Therefore, 0 + 7x² + 4 = 3x² + 4, which confirms that the correct answer is  3x3 + 5x2 +1.

3x3 + 5x2 +1 is the polynomial should be added in 3x³ 2x² +3 to get the polynomial 3x² +4.
