Answer:
(D): (-1,-6)
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-2,-5)[/tex]
[tex]m = -1[/tex]
Required
Find [tex](x_2,y_2)[/tex]
Slope (m) is calculated using:
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
Substitute values for m, x1 and x2
[tex]-1 = \frac{y_2 -(-5)}{x_2 - (-2)}[/tex]
[tex]-1 = \frac{y_2 +5}{x_2 +2}[/tex]
Cross Multiply:
[tex]-1(x_2 +2) = y_2 +5[/tex]
[tex]-x_2 -2 = y_2 +5[/tex]
Make y the subject
[tex]y_2 = -x_2 - 2 - 5[/tex]
[tex]y_2 = -x_2 - 7[/tex]
Only (D): (-1,-6) satisfy this condition:
Substitute -1 for x2 and -6 for y2.
[tex]-6 = -(-1) - 7[/tex]
[tex]-6 = 1- 7[/tex]
[tex]-6 =- 6[/tex]
Hence:
(D): (-1,-6) is true

SAS I think?
AB and BC are congruent
BD and BD share to same line so they are the same
Angle B is cut in half thus for they both equal so I think this is proven by SAS but I might be wrong.
area of rhombus is 60m sq.if its perimeter is 40 m sq. find its altitude
Answer:
Step-by-step explanation:
Para meter of rhombus is equals 40 m
So one side of rhombus is equal to 10 m
Now
Area of rhombus is equals to half into base into altitude
1/2*10*altitude=84
Altitude = 16.8m
What is the length of side EF in the triangle? Please give a step by step explanation, I'm having lots of trouble finding the solution. Thank you!
Answer:
EF = 8.8 cm
Step-by-step explanation:
In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/DE/^{2}[/tex] = [tex]/EF/^{2}[/tex] + [tex]/DF/^{2}[/tex]
[tex]/16.2/^{2}[/tex] = [tex]/EF/^{2}[/tex] + [tex]/13.6/^{2}[/tex]
262.44 = [tex]/EF/^{2}[/tex] + 184.96
[tex]/EF/^{2}[/tex] = 262.44 - 184.96
= 77.48
EF = [tex]\sqrt{77.48}[/tex]
= 8.8023
EF = 8.8 cm
The length of side EF is 8.8 cm.

In quadrilateral ABCD m < A= 90°
m 2 C = 50° and m < B = m D.
Find the degree measure of < B.
Answer:
m∠B = 170°
Step-by-step explanation:
Sum of all angles in quadrilateral is 360°:
m∠A + m∠B + m∠C + m∠D = 360°
m∠B = 360° - m∠A - m∠C - m∠D
m∠A = 90°
m∠B = m∠D= 50°
m∠B = 360° - 90° - 50° - 50° = 170°

find the angle which y= equals to root 3 x -4 makes with yaxis
9514 1404 393
Answer:
30°
Step-by-step explanation:
The angle a line makes with the x-axis is arctan(slope). Here, that is ...
angle with x-axis = arctan(√3) = 60°
So, the angle made with the y-axis is the complement of this:
angle with y-axis = 90° -60° = 30°
Find the slope intercept equation of the line
PLEASE HELP ME!!!!!
Answer:
y = -x + 6Step-by-step explanation:
Slope-intercept form:
y = mx + b, where m is slope and b is y-interceptWe see on the graph y-intercept is b = 6, point (0.6)
To find the slope we need a second point, choosing point (5, 1)
Using slope formula:
m = (1- 6)/(5 - 0) = -5/5 = -1So the line is:
y = -x + 6Answer:
y = -4/5x + 5
Step-by-step explanation:
the formula for slope intercept is y=mx+b.
m represents the slope of the line and b is the y intercept. all you have to do is replace those variables.
the y intercept is the point where the line crosses the y-axis (the line going up and down on the graph). (0,5) is the y intercept and so 5 would replace b in y=mx+b
so far we have y=mx+5
The slope is the vertical change between two points is called the rise, and the horizontal change is called the run. Starting from a point on the line you would move vertically until you're in line with another point. In this case, let's just use (0,5) from before. You would go up four to line up with a point. Then, move horizontally to meet up with the point and count the units, which is five here. And so, the slope would be 4/5.
And then you get the equation:
y=4/5x+b

Help me out with 5,6,7 (Geometry)
Problem 5
A counterexample could be a number like 6. Divide it over 2 and we get 6/2 = 3, which is a whole number. This shows 6 is a multiple of 2. However, 6/4 = 1.5 is not a whole number, so 6 is not divisible by 4. The overall claim is false.
======================================================
Problem 6
Let's say we are subtracting a positive number and a negative number. For instance, let's say we're subtracting 10 and -7
So,
10 minus -7 = 10 - (-7) = 10+7 = 17
When subtracting a negative, the two minus signs cancel to form a plus sign. The result we get is 17, which is larger than the greater number 10. So this is one counterexample that proves the claim to be false.
======================================================
Problem 7
Start with a circle. The circle can be any size. Plot four random points on the circle. The points can be anywhere you want. Let's label those points A,B,C,D. Form quadrilateral ABCD.
Now let's say we pick point A and pull it off the circle and pull it outside the circle. Points B,C and D remain on the circle. This is one example where we cannot draw a circle through this new arrangement of points. The circle goes through B,C, and D just fine; however, it doesn't go through point A. If you try to attempt to get the circle to go through A, then you'll have to pick B,C or D to ignore. In other words, you'll only be able to pick three points that the circle can go through. Therefore, a circle cannot be drawn as described for every quadrilateral.
Note: Any quadrilateral that has all four points on the same circle is known as a cyclic quadrilateral.

(x, y) --> (x + 14, y + 8)
Step-by-step explanation:
Look at 1 original point and its corresponding translated point.
Let's look at F and F'.
To go from F to F', you need to go right in x 14 units.
Then you need to go up in y 8 units.
The translation rule is to add 14 to x and 8 to y.
(x, y) --> (x + 14, y + 8)

During the round she answered eight 400 point questions correct and she answered nine 600 points questions incorrect. What was her score at the end of the round?
Answer:
7900 points
Step-by-step explanation:
Answer:
-2900 points
Step-by-step explanation:
8*400=3200
-700+3200=2500 points

We conclude that
[tex]4\frac{2}{3}[/tex] > [tex]\sqrt{21}[/tex]
Step-by-step explanation:
Given
[tex]\sqrt{21}[/tex][tex]4\frac{2}{3}[/tex]as
[tex]\:\sqrt{21}=4.58[/tex]
and
[tex]4\frac{2}{3}[/tex]
Convert mixed numbers to improper fraction:
[tex]a\frac{b}{c}=\frac{a\cdot \:c+b}{c}[/tex]
so
[tex]4\frac{2}{3}=\frac{4\cdot 3+2}{3}=\frac{14}{3}=4.67[/tex]
Thus,
[tex]\:\sqrt{21}=4.58[/tex]
[tex]4\frac{2}{3}=4.67[/tex]
as
4.67 > 4.58
so
[tex]4\frac{2}{3}[/tex] > [tex]\sqrt{21}[/tex]
Hence, we conclude that
[tex]4\frac{2}{3}[/tex] > [tex]\sqrt{21}[/tex]

-4 x f (8) + 3 x g(-7) HELP ASAP
Answer:
-32
Step-by-step explanation:
-4 + f(8) + 3 x g(-7) = ?
To find f(8), look at each of the f(x) function and find x = 8. The y value is the answer you will plug in for f(8). The same goes for g(-7), but you will be looking at the g(x) function at x = -7.
f(8) = -4
g(-7) = -8
Make sure you solve in the correct order using PEMDAS.
-4 + (-4) + 3 x (-8) = -32
