Answer:
A
Step-by-step explanation:
use both points to find the slope using the equation
y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3
then the y int can be any y point, so either -2 or 4. in this case they used 4.

Answer:
the second option, a=3 b=3 c=5
Step-by-step explanation:
first I would change them both into an improper fraction:
9/2 divided by 5/4
dividing is the same thing as mulitiplying by the reciprocal of the second number. so you would mulitply 9/2 x 4/5 = 36/10 and then you simplify back to a mixed number 3 6/10, 6/10 can be reduced so the final answer is 3 3/5.

solve each linear system by GRAPHING. CHECK YOUR ANSWER
2.) x - y = 6
2x = 12 + 2y
3.)1/2 x - y = 4
2y = x + 6
Answer:
2.) Infinitely many solutions
3.) No solutions
Step-by-step explanation:
To solve systems of equations graphically, you need to find where they intersect
2.) First put each equation in the form y=mx+b
x-y=6 -> y= x-6
2x=12+2y -> y= x-6
Then, graph each line
Since we have the same equation, the lines are on top of each other so there are infinitely many solutions as they intersect everywhere.
To check, plug a point in from the graph into both equations and you should get 0=0
3.) First put each equation in the form y=mx+b
1/2x-y=4 -> y=1/2x-4
2y=x+6 -> y=1/2x+3
Then, graph each line
Since the lines have the same slope but a different y intercept, the lines are parallel. Therefore, there are no solutions as they do not intersect.
To check your answer, you would one equation as the y in the other equation.
2(1/2x-4)=x+6, then solve for x
Then plug that x into the original equations, and you'll see they are not equal. Hope that helps!

Answer:
11/13
Step-by-step explanation:
3/13, 5/13, 7/13, 9/13, 11/13
3/13
3/13 + 2/13 = 5/13
5/13 + 2/13 = 7/13
7/13 + 2/13 = 9/13
9/13 + 2/13 = 11/13

8th grade math! If you know the answer to this problem please interact(:
Answer:
the third one (-2,1)
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
so solving the first one we get
y=2x+5
and the second one we get
y=5x+10+1
y=5x+11
substiuting we get
2x+5=5x+11
3x=-6
x=-2
and y= 1
so it would be C

solve the following for x 4(x+2) = 6x
Answer:
x = 4
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
4(x+2)=6x
distribute 4:
4x+8=6x
Subtract 4x from each side:
8=2x
Divide both sides by 2:
x=4

Find the difference. Write your answer in the simplest form
3/4 - 3/8
Find the sum. Write your answer in the simplest form
2/7 + 2/5
Answer:
#1. 3/8 and #2. 27/35
Step-by-step explanation:
3/4 - 3/8 change to 6/8 - 3/8 = 3/8 can not reduce
2/7 + 2/5 change to 10/35 + 17/35 = 27/35 can not reduce
Answer:
3/8
Step-by-step explanation:
3/4 - 3/8
= 3*2/4*2 - 3/8
= 6/8 - 3/8
= 6-3/8
= 3/8
Answer:
24/35
Step-by-step explanation:
2/7 + 2/5
= 2*5/7*5 + 2*7/5*7
= 10/35 + 14/35
= 10+14/35
=24/35
The graph of a translated exponential function is shown below. Its parent function is y = 4x.
If the graph is asymptotic to y = -3 and contains the points (2, -2) and (3, 1), what is the equation of the function?
PLEASE HURRY!
The graph of a translated exponential function is shown below. Its parent function is y = 4x.?
The function has been translated down 3 units and right 2 units. The equation of the graphed function is

Factor the following binomial using the difference of squares?
(49x^2 – 9)
find the slope of the line going through the point (0,3) and (0,4)
Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
[tex]\frac{(4)-(3)}{(0)-(0)} \\= \frac{4-3}{0-0}\\=\frac{1}{0}[/tex]
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)

Answer: 180
Step-by-step explanation:
When added together, Interior angles of a triangle are always equal to 180 degrees.
Answer:
∠FHG=120°
Step-by-step explanation:
first you calculate the angles of the triangle NGH
this is isoceles triangle, so there's 2 equal angles
and as shown, the 2 same angles are having 2 lines in each one, this 2 lines represents that the 2 angles are same
so both are 20°
any triangle has a sum of 180° of interior angles
so 180-(H+G)=the angle below N
180-(20+20)=140°
the angle below N is same as N because they're vertically opposite
140 is an exterior angle
and the exterior angle is equal to the 2 far angles
140=40+∠FHN
140-40=100°
so ∠FHN=100°
∠FHN+∠NHG=∠FHG
100+20=120°
so ∠FHG=120°

Find the standard form of the equation for the conic section represented by x^2 + 10x + 6y = 47.
Answer:
The standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]
Step-by-step explanation:
We know that:
[tex]4p\left(y-k\right)=\left(x-h\right)^2[/tex] is the standard equation for an up-down facing Parabola with vertex at (h, k), and focal length |p|.
Given the equation
[tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex]
Rewriting the equation in the standard form
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]
Thus,
The vertex (h, k) = (-5, 12)
Please also check the attached graph.
Therefore, the standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]
where
vertex (h, k) = (-5, 12)
