The equation of the line with slope -3 that goes through the point (-9,-7) can be written in the form y=mx+b
where m is:
and where b is:
Answers
Answer:y= -9x-25
Step-by-step explanation: Write the slope-intercept form of an equation of the line with slope -9 and passes through the point (-2, -7).
--------
Form:: y = mx + b
Solve for "b"::
-7 = -9*-2 + b
-7 = 18 + b
b = -25
-----
Equation:
y = -9x - 25
---------------
Cheers,
Stan H.
-----------
point slope formula
y-y1=m(x-x1)
y+7= -9(x+2). Notice that we are subtracting a negative, so we have to add.
y+7=-9x-18
y= -9x-25

Answer:
a triangle that is rotated about a given point.
Step-by-step explanation:
Answer:
If a dilation is applied to a triangle, then the image must be similar.
Step-by-step explanation:
We have been given an incomplete sentence. We are supposed to fill in the given blank.
Sentence:
If a dilation is applied to a triangle, then the image must be _____.
Since we know that after dilating a figure by a scale factor, the resulting image will be either bigger or smaller than the original figure depending on the scale factor.
If the scale factor is greater than one, so resulting figure will be bigger than the original figure.
If the scale factor is less than one, so resulting figure will be smaller than the original figure.
Since all the angles of a triangle add up-to 180 degrees, so the measure of angles of the resulting figure will be same as the original triangle.
Since the corresponding sides of pre-image and image are proportional, so both triangles will be similar not congruent.

Chaleah deposited $700 in a new account that earns 5 simple interest. After 4 years, how much interest will she have earned? How much total money will Chaleah have after 4 years
Answers
Answer:
FV= $875
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $700
Simple interest (i)= 5% = 0.05
Number of periods (n)= 4 years
To calculate the future value (FV), we need to use the following formula:
FV= PV*i*n + PV
FV= 700*0.05*5 + 700
FV= $875

Slope = -3
y-intercept = (0,-4)
Equation: y = -3x-4
Step-by-step explanation:
We can take any two input-output pairs from the table to find the equation of given function.
Linear function is given by:
[tex]y =mx+b[/tex]
Here m is the gradient of the functions which is defined as:
[tex]m = \frac{rise}{run} = \frac{y_2-y_1}{x_2-x_1}[/tex]
The input-output pairs are:
(x1,y1) = (-1,-1)
(x2,y2) = (0,-4)
First of all,
[tex]m = \frac{-4-(-1)}{0-(-1)}\\= \frac{-4+1}{1} = -3[/tex]
Putting the value of slope in the equation
[tex]y = -3x+b[/tex]
Putting (-1,-1) in the equation
[tex]-1 = -3(-1)+b\\-1 = 3+b\\b = -1-3\\b = -4[/tex]
The equation will be:
[tex]y = -3x-4[/tex]
Hence,
Slope = -3
y-intercept = (0,-4)
Equation: y = -3x-4

What is the equation of the line of symmetry for the parabola represented by the equation y=−x^2+2x+6?
Answers
Answer:
the answer would be t56 im guess ing along with x
Step-by-step explanation:
The line of symmetry for the parabola represented by the equation is
x = 1.
What is a parabola?A symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity follows a curve of this shape.
Given an equation of a parabola, y = -x²+2x+6
Factorizing the equation, we get,
x = 1+√7 or x = 1-√7
We know that the line of symmetry of a parabola is equal to the x-coordinate of the vertex of the parabola.
We also know that the x-coordinate of the vertex of a parabola is equal to the average of zeros. So the x-coordinate of the vertex of the parabola would be:
(1+√7 + 1-√7)/2 = 1
Hence, the equation represents the line of symmetry of the given parabola is x=1.

You also must have x ≥ 0 and y ≥ 0, in order for this to make sense.
When you graph these four inequalities, you will obtain a region in the first quadrant. I will let you try to find it by graphing the first two inequalities and determining the shaded region.
