What is the y-intercept of the line whose equation is y=-x-2?
Select one:
a.-2
b. 2.
c.1
D,.1
Answer:
-2
Step-by-step explanation:
If we have an equation of the form y = mx +b then the y-intercept is b.
So now here we have y =-x - 2. Therefore b = -2 and we conclude the y-intercept is -2.

can someone find the domain and range in this graph i’m having trouble
To find the domain of graph, we notice at the point on the left and the right.
Domain is the set of all x-values, so we perceive in a horizontal line or x-axis.
The first point on left is at x = -1 and the second point on the right is at x = 1.
Since the points are opened and therefore, the Inequality signs can only be > or <.
Therefore, the domain is -1 < x < 1
To find the range, similar to domain but we perceive vertical line or y-axis. Range is the set of all y-values.
We notice that the minimum point is -1 or y = - 1 and maximum point at 1 or y = 1.
Therefore, the range is -1 < y < 1

A: 0 only
B: -6 only
C: -2, 1, or 3 only
D: -6, -2, 1, or 3 only
Answer:
C
Step-by-step explanation:
note y = f(x) = 0
y = 0 is the x- axis
We are looking for values of x on the x- axis where the graph crosses/touches

Answer:
A
Step-by-step explanation:
All you have to do is replace the x value in the equation g(x) with whatever value x is in the tables given. An example would be as follows:
x = -2 replace x with -2
-1/2( 4(-2) + 6 )
now use pemdas to finish the equation.
you will get g(x) = 1.
Therefore, your answer is the first table, (aka A)

what are the coordinates of point G ,which divides DE un the ratio 2:3?
Answer:
(5, 7.8)
Step-by-step explanation:
There are several ways to solve this problem, but all of them involve similar triangles and ratios.
See the attached image.
The horizontal distance between points D and E is 11 - 1 = 10. If a segment 10 units long is divided in the ratio 2:3 (as shown by the two smaller segments of length a and b), then
[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{10}=\frac{2}{5}[/tex]
"Cross-multiply" to get
5a = 20
a = 4
To get the x-coordinate of point G, add 4 to 1, the x-coordinate of D.
The x-coordinate of G is 1 + 4 = 5.
The same idea can be used on the second coordinate of G.
The vertical distance from D to E is 15 - 3 = 12.
[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{12}=\frac{2}{5}[/tex]
5a = 24
a = 24/5 = 4.8
The y=coordinate of G is 3 + 4.8 = 7.8

What is the rounding of a number?The action of forming anything into a circle. Mathematics. the act of substituting a number with one that is roughly equivalent in value but has fewer digits: To the closest dollar, rounding $27.68 results in $28. a comparable procedure that identifies one of several rules.
The decimal number is given below.
⇒ 6.4 − 4.2
⇒ 2.2
Round the number 2.2 to the nearest whole number.
If the decimal number is more than 0.5, then the ones place after the decimal will be increased by one.
In the decimal number is 2, then the ones place number 2 remains the same as 2.
Round the number 2.2 nearest whole number will be 2. Then the correct option is C.

Answer:
D. x = 10
Step-by-step explanation:
Perimeter = the sum of all sides lengths
Perimeter = 30 (in this case)
so...
[tex]((x-5)+x)2=30[/tex]
Step 1. Dividing 3 to both sides
[tex]((x-5)+x)=15[/tex]
Step 2. Add 5 to both sides
[tex]x+x=20[/tex]
Step 3. Solve for x
Since x + x = 20, to solve for one of the x means solving for the other x
so since 2 x's are being added with the same value, divide 20 by 2.
x = 10

PLS ANS CLEARLY
The rule is
[tex]\frac{d}{dx}x^n = nx^{n-1}[/tex]
which is the power rule. You pull down the exponent to place it as the coefficient. So that explains the 1/2 pull out front. Then we subtract 1 from the exponent.
The expression you wrote can be simplified or rewritten like this
[tex]\frac{d}{dx}x^n = nx^{n-1}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}x^{\frac{1}{2}-1}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}x^{-\frac{1}{2}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}\frac{1}{x^{\frac{1}{2}}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2x^{\frac{1}{2}}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2\sqrt{x}}}\\\\[/tex]

Conor's house is 3000 m from Oscar's house.
How far apart in cm would they be on a map where 1 cm represents 750 m?
Answer:
4 cm
Step-by-step explanation:
A ratio shows us the number of times a number contains another number. The distance between Conor's house and Oscar's house on the map will be 4 cm.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that 1 cm on the map represents 750 m in real. Therefore, we can write the ratio as,
Ratio = Length on the map / Length in real = 1cm / 750m
Now, it is also mentioned that Conor's house is 3000 m from Oscar's house. Therefore, the ratio can be written as,
Ratio = Length between the house in map / Length between the house in real = 1 cm /750 m
Length between the house in map = (1 cm × Length between the house in real) / 750 m
Length between the house in map = (1 cm × 3000m) / 750 m
Length between the house in the map = 4 cm
Hence, the distance between Conor's house and Oscar's house on the map will be 4 cm.
