Find the value of k if it is known that the line y=kx+2 goes through point: (-7,12)
Answer:
-10/7
Step-by-step explanation:
y=kx+2 (-7, 12)
12=k(-7)+2
12=-7k+2
-7k=12-2
-7k=10
k=10/-7

Answer:
x = 79 y = 22
Step-by-step explanation:
x would be the same as the other side so 79 * 2 would be 158. A whole triangle is 180. 180 - 158 = 22
Describe, in words, how the figure at the right was translated.
Answer:
8 up, 6 left
Step-by-step explanation:
Locate any point from triangle A and go up 8 steps to get on the same level as triangle A'. Then, move to the left 6 steps.
The graph translated 6 unit left and 8 unit upward.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, A figure "A" that translated at different position in cartesian plane.
Since, A translation is when a geometric figure slides up, down, left or right on the coordinate plane. The figure moves its location, but doesn't change its orientation. It also doesn't change its size or shape.
Thus, we can observe only one point on the figure and calculate the movement of the figure.
Lets focus on the left bottom corner of the figure.
It moves from the coordinates (1, -5) to the coordinates ( -5, 3)
Since Horizontally translating a graph is equivalent to shifting the base graph left or right in the direction of the x-axis
So, we can say it translated to the lefty by 6 unit.
Same it goes with vertical translation.
Therefore, The graph translated 6 unit left and 8 unit upward.

1. m<C = 48°.
2. <X = <Y.
Explanation :<ABD = <CDB = 62°
<BDA = <DBC = 70°
<DBC + <BCD + <CDB = 180°
70° + <BCD + 62° = 180°
132° + <BCD = 180°
<BCD = 180° - 132°
<BCD = 48°

Answer:
SA=78.5
Step-by-step explanation:
Find the area to all visible sides. 4*2.5=10, 10*2 (because there is two of these shapes) is 20. 4.5*4=18, 18*2=36. Finally, 4.5*2.5=11.25, 11.25*2=22.5.
20+36+22.5=78.5

The sum of two numbers is –11. The difference of the two numbers is –7. What is the product of the two numbers?
Answer:
18
Step-by-step explanation:
According to the numbers the both numbers have to be negative
subtracting a negative will be the same as addition and so thats why the difference is bigger.
now its time for guess and check.
-6+-5
-11
but -6-(-5)=-1
so lets try
-9+(-2)=-11
-9-(-2)=-7
yay
so the product is
(-9)*(-2)=18

Find the vertex of the function given below.
y= 2x2 + 4x + 1
Answer:
vertex is (-1,-1)
Step-by-step explanation:
2 ways
1. get into vertex form y=a(x-h)^2+k
2. use math hacks
1.
vertex is (h,k) in y=a(x-h)^2+k
complete square
y=(2x^2+4x)+1
y=2(x^2+2x)+1
y=2(x^2+2x+1-1)+1
y=2((x+1)^2-1)+1
y=2(x+1)^2-2+1
y=2(x+1)^2-1
y=2(x-(-1))^2+(-1)
vertex is (-1,-1)
2.hack way
in form y=ax^2+bx+c
x value of vvertex is -b/2a
given
y=2x^2+4x+1
b=4, a=2
xvaluevertex=-4/(2*2)
xvaluevertex=-4/4=-1
sub back to find y value
y=2(-1)^2+4(-1)+1
y=2(1)-4+1
y=2-4+1
y=-1
y value is -1
Answer:
(-1,-1)
Step-by-step explanation:
To find the x coordinate, we use the formular x = -b/2a where b=4 and a = 2 from the given function.
hence x = -(4)/2(2) = -1
then to get the y coordinate we substitute the value of x into the given function, so y = 2(-1)^2+4(-1)+1 = -1
therefore, the vertex is (-1,-1)

Answer:
60°
Step-by-step explanation:
the relationship between angle RST and its arc TR is:
2m∠(RST)=m(arcTR);
using this formula m∠(RST)=0.5*m(arcTR);
m∠(RST)=60°
Answer:
<S = 60
Step-by-step explanation:
The arc TR and the central angle (T to the center then to R ) are equal.
So the Central angle is 120o
S anywhere on the minor arc is 1/2 the central angle.
<S = 1/2 120
<S = 60
7x + 2y=-12
Y=-3x-4
Answer:
x=-4
Step-by-step explanation:
X would be -4 because if you distribute 2 to (-3x-4) it would give you (-6x-8) and then collecting like terms you would get (x-8=-12) then you would add 8 to -12 whih would equal -4.
II 24x2 =52
in What base at the
number?
Answer: WE are multiplying in base 6
Step-by-step explanation:
24 x 2 = 52 can only be in base 6
because 2¹ 4 2 x 4 = 8/6 = 1 rem 2.
x 2₆ 2 x 2 + 1= 5
5 2
From the above , we can see theta 24 x 2 = 52 can only be in base 6.
Because only 2 x 4 = 12 can be possible in base 6.
Counting in base 6 gives us that after 5, the next number is 10. Just like counting in the common base 10, which after 9 we get 1 0
in Base 10--- 1, 2,3, 4,5, 6,7,8,9,10
in Base 6--- 1, 2, 3,4,5,10,11,12, 13,14 and so o
