What is the y-intercept:
7x + y = 10
Answer:
10
Step-by-step explanation:
7(0)+y=10
y=10
Answer: (0, 10)
Step-by-step explanation:
The given expression is in the standard form of linear equations: Ax + By = C, where A and B are constants.
The definition of y-intercept is the point that intersects with the y-axis, meaning that the [x] value of the point will be zero.
To find the y-intercept of an equation, substitute the [x] variable with 0, as mentioned above, the [x] value of a y-intercept is 0.
[tex]7x+y=10\\[/tex]
[tex]7(0)+y=10[/tex]
[tex]0+y=10[/tex]
[tex]y=10[/tex]
As we find the [y] value is 10, while the given [x] value is 0, therefore, the y-intercept of [tex]7x+y=10[/tex] is [tex]\boxed{(0,10)}[/tex].
Hope this helps!! :)

The cost for a business to produce "x" television commercials in 1 year is $225x + $17,000. How many commercials can the company produce in 1 year at a cost of $35,000
We are required to find how many commercials the company can produce in year at a cost of $35,000
The company can produce 80 commercials in year at a cost of $35,000
Given:
C(x) = $225x + $17,000
If C(x) = $35,000
Then,
C(x) = $225x + $17,000
35,000 = 225x + 17,000
subtract 17,000 from both sides
35,000 - 17,000 = 225x
18000 = 225x
divide both sides by 225
x = 18,000 / 225
x = 80
Therefore, the company can produce 80 commercials in year at a cost of $35,000

You are given that a = 6.54 (to 3 significant figures) and b = 123 (to 3 significant figures).
Calculate upper and lower bounds for each of the following, give your answers to 3 significant figures:
(a) a + b
(b) ab
(c) a/b
(d) b - 1/a
The upper and lower bounds for the numbers are illustrations of approximation
How to calculate the upper and lower boundsThe numbers are given as:
a = 6.54 (to 3 significant figures)
b = 123 (to 3 significant figures)
(a) a + b
We have:
a + b = 6.54 + 123
a + b = 129.54
When approximated, the bounds to three significant digits are:
Lower bound = 129
Upper bound = 130.1
(b) ab
We have:
ab = 6.54 * 123
a + b = 804.42
When approximated, the bounds to three significant digits are:
Lower bound = 804
Upper bound = 805
(c) a/b
We have:
a/b = 6.54/123
a/b = 0.0531707317
When approximated, the bounds to three significant digits are:
Lower bound = 0.0531
Upper bound = 0.0532
(d) b - 1/a
We have:
b - 1/a = 123 - 1/6.54
b - 1/a = 122.847094801
When approximated, the bounds to three significant digits are:
Lower bound = 122

Point A lies on a number line at 6. Point C lies between points B and A at 1.875. The ratio AC : AB = 3 : 5. What is the length of A B?
A. AB = 15 units
B. AB = 8.75 units
C. AB = 6.875 units
D. AB = 11 units
Plz Answer ASAP! Thank you!
Answer: C, 6.875 is the correct answer
Step-by-step explanation:
AC = 6 - 1.875 = 4.125
AB = 5/3 * 4.125 = 6.875
The measure of AB is 6.875. Therefore, option C is the correct answer.
Given that, the ratio AC: AB = 3: 5.
What is the ratio?In mathematics, a ratio indicates how many times one number contains another.
AC = 6 - 1.875 = 4.125
AB = 5/3 * 4.125 = 6.875

Step-by-step explanation:
2x² - 5x + 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 3 = 6 and sum = - 5
The factors are - 2 and - 3
Use these factors to split the x- term
2x² - 2x - 3x + 3 ( factor the first/second and third/fourth terms )
2x(x - 1) - 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x - 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Which of the following pair of sets is an example of disjoint sets?
X={rational numbers} and Y={whole numbers}
P={multiples of 2} and Q={multiples of 3}
G={multiples of 5} and H={multiples of 10}
E={even numbers} and F={odd numbers}
We want to see which pair of sets is disjoint, this is, see which pair of sets does not share any element.
The correct option is: E = {even numbers} and F = {odd numbers}
So we only need to see which one is the pair of sets that does not share any element, so we can analyze the given options and see if we can find a number that belongs to both sets.
1) X = {rational numbers} and Y = {whole numbers}
Any whole number is also a rational number, for example:
2 = 4/2
So we can write the number 2 as a quotient of two integers, then we can see that these sets share elements.
2) P={multiples of 2} and Q={multiples of 3}
The number 6 is a multiple of both 2 and 3, thus the number 6 belongs to bot sets, then the sets are not disjoint.
3) G={multiples of 5} and H={multiples of 10}
10 is a multiple of 10 and 5, so the number 10 belongs to both sets, thus the sets are not disjoint.
4) E={even numbers} and F={odd numbers}
We define the even numbers as the ones divisible by 2, while the odd numbers are those that are not divisible by 2. Then by definition, there is no even number that is also odd.
Then we can see that these two sets are disjoints, and this is the correct option.
