a. The ____________________ of a graph is the location where the graph crosses the −axis.
Answer:
x- intercept
Step-by-step explanation:
Where a graph crosses the x- axis is called the x- intercept.
Where a graph crosses the y- axis is called the y- intercept
P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7.
Answer:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = [tex]\frac{k}{8}[/tex] ( multiply both sides by 8 )
56 = k
P = [tex]\frac{56}{x}[/tex] ← equation of variation
When x = 7 , then
P = [tex]\frac{56}{7}[/tex] = 8
The value of P when x = 7 is 7 and can be determined by using the arithmetic operations and given data.
Given :
P varies inversely with x.P = 7 when x = 8.The following steps can be used to determine the value of P when (x = 7):
Step 1 - Given that P varies inversely with x. That is:
[tex]\rm P \;\alpha \;\dfrac{1}{x}[/tex]
Step 2 - The above expression can be written as:
Px = K ---- (1)
where K is the proportionality constant.
Step 3 - Now, it is given that P = 7 when x = 8. Put the value of P and x in the above equation.
[tex]\rm 7\times 8 = K[/tex]
56 = K
Step 4 - Put the value of K = 56 and x = 7 in the equation (1).
[tex]\rm P \times 8=56[/tex]
P = 7
So, when x = 7 the value of P is 7.

Given that the radius of the circle is
2 yd.
Step-by-step explanation:
Area of first triangle = 1/2bh
the base of the triangle = the radius of the semi-circle = 2yd
height = 5yd
Area = 1/2(5yd)(2yd)
A = 5yd(yd)
A = 5y^2d^2 squared units.
since the second triangle also has the same dimensions as the first triangle
hence:
Area of the second triangle = 5y^2d^2 squared units.
Area of semi-circle = πr^2
Area = π(2yd)^2
A = 4πy^2d^2 squared units

THE SUM OF TWO NUMBERS IS 54. IF THE SMALLER NUMBER IS 6 LESS THAN THE BIGGER ONE, FIND THE NUMBERS. (STEP BY STEP PLZ)
Answer:
24 and 30
Step-by-step explanation:
The sum of two numbers is 54. Let's use the variables x and y to represent theses numbers:
x + y = 54
The smaller number is 6 less than the bigger one. Let's say that x is the smaller number and y is the bigger number:
y - 6 = x
Now we know that x is equivalent to y - 6. So, let's replace x with y - 6 in the original equation:
x + y = 54
y - 6 + y = 54
Combine like terms:
2y - 6 = 54
Now we can solve for y:
2y - 6 = 54
Add 6 to both sides of the equation to isolate the 2y:
2y = 60
Divide both sides by 2 to find the value of y:
y = 30
Now that we know the value of y, we can solve for x:
y - 6 = x
30 - 6 = x
24 = x
The value of the two numbers is 24 and 30.

Step-by-step explanation
When rounding, you want the number to change as little as possible. It is easier for the number to be 250 instead of 200 because 229 is closer to 250. in the same way, 3.22 is closer to 3 than 4. Now to check this, if you do 229 x 3.22, you get 737.38. Now looking at the answer choices, this is most definitely closest to 750. Given all this, I think it is safe to say D is the answer.
Hope this helps!

You have to make sure to add like terms. In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.
