Write an equation of the line that passes through (-4,3) and (0,6).
An equation is y =
Answers
Answer:
y= ¾x +6
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the gradient first.
[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]
Using the formula above,
[tex]m = \frac{6 - 3}{0 - ( - 4)} \\ m = \frac{3}{4} [/tex]
subst. the value of m into the equation.
[tex]y = \frac{3}{4} x + c[/tex]
To find c, substitute a coordinate.
When x=0, y=6,
[tex]6 = \frac{3}{4} (0) + c \\ 6 = 0 + c \\ c = 6[/tex]
Thus, the equation of the line is [tex]y = \frac{3}{4} x + 6[/tex].

Answers
Answer:
The y-intercept of function g located at (0,2)
Step-by-step explanation:
Function :[tex]g(x)=x^2+2[/tex]
g(x) is a transformation of the quadratic parent function
We are supposed to find the where is the y-intercept of function g located
y intercept = the y-coordinate of a point where a line, curve, or surface intersects the y-axis i.e. x =0
So, substitute x = 0 in function
g(x)=x^2+2
g(0)=0^2+2
g(0)=2
So,(x,y)=(0,2)
So, The y-intercept of function g located at (0,2)

If the dilated image is larger than the pre-image, then the scale factor of the dilation is less than 1.
Answers
Answer:
False
Step-by-step explanation:
In order for the dilated image to become larger, it has to have a scale factor that is more than one not less than one.
False, Because If the scale factor is greater than 1, the image is larger than the preimage.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We know that;
If the scale factor is between 0 and 1, the image is smaller than the preimage. Dilations with a scale factor between 0 and 1 are called reductions.
And, If the scale factor is greater than 1, the image is larger than the preimage. Dilations with a scale factor greater than 1 are called enlargements.
Thus, The given statement is false.

What is the equation of the graphed line written in standard

X-4y=4
X+4y=4
Y=1/4x-1
Y=-1/4x-1
Answers
Explanation:
Choices C and D are in slope intercept form, and not standard form, so we can rule them out. It's been choice A and choice B.
Solve for y in choice A, and you should get y = (1/4)x-1. The slope is 1/4. The positive slope tells us the line moves uphill as you move from left to right. In contrast, x+4y = 4 has a negative slope because it solves to y = (-1/4)x+1. Therefore, choice B can be eliminated.
To confirm that choice A is the correct answer, plug in each point and see if we get a true equation. Let's start with (0,-1)
Plug in (x,y) = (0,-1)
x-4y = 4
0-4(-1) = 4 ... replace x with 0, replace y with -1
0+4 = 4
4 = 4 ... true equation, so the point (0,-1) works
Now try the other point
x-4y = 4
4-4(0) = 4 .... plug in (x,y) = (4,0)
4-0 = 4
4 = 4 ... works as well
Both points make the equation true, so they are both on the same line.

What is Coordinate Geometry?A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
Divide AB into three equal parts
[tex]X_{c}-X_{a}=\frac{1}{3} (X_{B}-X_{D})[/tex]
=3
[tex]Y_{a}-Y_{c}=\frac{1}{3} (Y_{A}-Y_{B})[/tex]
=3
So C is (0, 3)
[tex]X_{B} -X_{D} =\frac{1}{3} \times 9[/tex]
=3
[tex]Y_{D} -Y_{B} =\frac{1}{3} \times 9[/tex]
=3
So D coordinates are (3, 0)
Hence, if AB is divided into three equal parts then coordinates of C is (0, 3) and D coordinates are (3, 0)

100 POINTS NEEDED RIGHT NOW! On a graph plot the points where the following function crosses the x-axis and y-axis g(x) = -5^x+5
Answers
Answer:
see below
Step-by-step explanation:
X-AXIS
when a graph intersects the x-axis, the y value is always 0.
Ex. Points (1,0), (-5,0), (-3,0), (6,0), etc. are all on the x-axis because y = 0.
to find where the graph crosses the x-axis, let y or g(x) = 0
0 = -5^x + 5 subtract 5 from both sides
-5 = -5^x if x is 1, that would produce -5 = -5
(1,0) x axis
Y-AXIS
when a graph intersects the y-axis, the x value is always 0.
Ex. Points (0, 1), (0, -2), (0, 3), etc. all lie on the y-axis because x = 0.
to find where teh graph crosses the y-axis, let x = 0

How are the solution sets to s<3 and |s|<3 different ?
Answers
Answer:
The solution set for [tex]s<3[/tex] would be (-∞,3)
The solution set for [tex]|s|<3[/tex] would be (-3,3)
Step-by-step explanation:
The solution set for [tex]s<3[/tex] can be any number that is lower than 3.
When we have the inequality [tex]|s|<3[/tex], we need to rewrite this without the absolute values to find our answer
[tex]|s|<3[/tex]
[tex]s<[/tex] ± [tex]3[/tex]
This can be be split into [tex]s<3, s<-3[/tex]
But, there one thing that needs to be done to the inequality with the-3. As we multiplied it by a -1 to make it negative, we must reverse the sign of the inequality. This leaves us with [tex]s<3, s>-3[/tex]
Now, we can combine these to get one inequality
