The x intercept for any curve is the value of the x coordinate of the point where the graph cuts the x-axis, or we can say that the x-intercept is the value of the x coordinate of a point where the value of y coordinate is equal to zero.
Let us learn more about the x-intercept along with its formula and examples.
What is X Intercept?In the linear equation, we read that the general form is represented as y = mx + b, where m and b are constants. The x-intercept is the point or the coordinate from where the line crosses and that lies at the x-axis of the plane. This means the y-coordinate value of the respective linear equation will always be equal to 0 when it crosses the x-axis. For x-intercept, the y-coordinate is zero and for the y-intercept, the x-coordinate is zero. the x-intercept is also known as horizontal intercept.
X Intercept FormulaThere are various formulas and equations associated with intercepts. Below listed are a few general formulas mostly used. All these formulas are derived by substituting y = 0 in the equation and solving for x.
The general form of a straight line is: ax+by+c=0, where a,b,c are constants. The x intercept of the line can be obtained by putting y = 0, x-intercept = −c/aThe slope-intercept form of a straight line is: y = mx+c, where m is the slope of the line and c is the y-intercept. The x-intercept of the line can be obtained by putting y=0, x-intercept = −c/mThe point-slope form of a straight line is y−b = m (x−a), where m is the slope of the line, (a,b) is a point on the line. The x-intercept of the line can be obtained by putting y = 0, x-intercept = (am−b)/m.The intercept form of a straight line is x/a + y/b = 1 where (a, 0) is its x-intercept and (0, b) is its y-intercept.X Intercept on a GraphTo find the x-intercept of a line of the form y = mx+b, substitute y = 0.
Example: To calculate the x-intercept of any line for example the line y = 2x−4, put y = 0 in the equation of a line.
Solution:
0 = 2x−4
4 = 2x
2 = x
So, the x-intercept of the line y=2x−4 is 2
Similarly, by substituting x = 0, we can find the y-intercept
y = 2(0)−4
y= -4

Functions can be represented using equations and graphs Both f(x) and g(x) include domain values of [4, ∞) and range values of [0, ∞), and both functions have a y-intercept in common.
How to determine the key features?The domain of the function is defined as the set of the numbers we are allowed to put in the function while the range is the assumed data put in the function.
The functions are given as:

A rectangle prism with a length of 12.5 cm and a width of 7.5 cm has a
volume of 937.50 cm?. What is the height of the rectangular prism?
Answers
Answer:
Height = 10 cm
Step-by-step explanation:
To find the height of the rectangular prism, we need to use the volume equation of rectangular prisms:
V = l * w * h
l = length
w = width
h = height
We know the length (12.5 cm), width (7.5 cm), and the volume (937.50 [tex]cm^{3}[/tex]).
Plug all these into the equation and solve for the height:
937.50 = (12.5)(7.5)h
937.50 = 93.75h Multiply 12.5 by 7.5
10 = h Divide 937.50 by 93.75 to get h.
Therefore, the height of the rectangular prism is 10 cm.
Let's check our answer by plugging all values into the volume equation:
937.50 = (12.5)(7.5)(10)
937.50 = 93.75 (10)
937.50 = 937.50 Both values are equal so 10 is correct!
I hope this helps! Good luck!

P(X > 8) = 5/18
P(X mod 5 ≠ 0) = 29/36
Step-by-step explanation:
You want various probabilities related to the sum of two dice.
Greater than 8Please refer to the attached chart of possible outcomes. There are 4 ways to roll a 9, 3 ways to roll a 10, 2 ways to roll 11, and one way to roll 12. That means there are 4+3+2+1 = 10 ways to roll a number greater than 8.
P(X > 8) = 10/36 = 5/18
Not divisible by 5It is easier to count results that are divisible by 5. Then the difference between that number and 36 will be the number of outcomes not divisible by 5.
5 can be rolled 4 ways, and 10 can be rolled 3 ways. A total of 4+3 = 7 of the 36 outcomes are divisible by 5. That means 36 -7 = 29 are not divisible by 5.
P(X not divisible by 5) = 29/36

Answer:
238 cm
Step-by-step explanation:
so we have a scale factor of 17: 1
originally we had the dimensions: 3cm by 4m
now we have 3*17 by 4*17 = 51 cm by 68 cm
Perimeter = 2*51 + 2*68 = 238 cm
Answer:
360 cm
Step-by-step explanation:
The height of the magnified image is the product of the height of the original image and the scale factor.
h=15(7) cm.
Simplify.
h=105 cm.
The width of the magnified image is the product of the width of the original image and the scale factor.
w=15(5) cm.
Simplify.
w=75 cm.
So, the perimeter is
P=2(75)+2(105) cm.
Simplify.
P=360 cm.
Therefore, the perimeter of the painting is 360 cm.

Hi!
Given these two equations:
[tex]x = y + 8[/tex]
[tex]x + 4 = 2(y + 4)[/tex]
We want to solve using the substitution method. Knowing that x is equal to y + 8, we can simply plug in 'y + 8' in for x in the second equation, like so:
[tex](y+8)+4=2(y+4)[/tex]
Combine like terms on both sides:
[tex]y+12=2y+8[/tex]
Subtract y from both sides:
[tex]12=y+8[/tex]
Subtract 8 from both sides:
[tex]y=4[/tex]
Now, we can simply plug the y value in to the first equation, and solve for x:
[tex]x=4+8[/tex]
Simplify:
[tex]x=12[/tex]
Therefore, x is equal to 12 and y is equal to 4.Learn more about the substitution (and also elimination!) method here:

There are a total of 66 students in the
fourth grade at North Elementary
school. Class A has five more
students than Class B. Class C has 2
less students than Class B. How
many students are in class A?
Answers
Answer:
A = 26
Step-by-step explanation:
sum of students = classA + classB + classC
let's say classA = A, classB = B, and classC = C
A + B + C = 66
class A has five more students than class B, so A = 5 more than B so A = 5+B
class C has 2 less students than class B, so C = 2 less than class B = B -2, so C = B-2
A + B + C = 66
A = 5+B
C = B-2
substitute 5+B for A and B-2 for C in the first equation to limit this to one variable (B)
(5+B) + B + (B-2) = 66
3B + 3 = 66
subtract 3 from both sides to isolate the variable and its coefficient
3B = 63
divide both sides by 3 to solve for B
B = 21
A = 5 + B = 5 + 21 = 26

What is the length of side AB of parallelogram ABCD?
units
4g - 8
B
q+4
Answers
Answer:
8 units
Step-by-step explanation:
» Concepts
Parallelogram Side Theorem states that the opposite sides of a parallelogram are congruent, meaning they have the same length.
» Application
In this case, we're asked to apply the theorem to find the value of q and then find the length of AB. Thus, we have to set up the equation 4q - 8 = q + 4.
» Solving
Step 1: Subtract q from both sides.
[tex]4q-8-q=q+4-q[/tex] [tex]3q-8=4[/tex]Step 2: Add 8 to both sides.
[tex]3q-8+8=4+8[/tex] [tex]3q=12[/tex]Step 3: Divide both sides by 3.
[tex]3q/3 = 12/3[/tex] [tex]q=4[/tex]Step 4: Plug in the value of q for side AB.
[tex]4(4)-8[/tex] [tex]16-8[/tex] [tex]8[/tex]Therefore, the answer is 8 units.
