Step-by-step explanation:
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.

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.

Im checking my test. whats the answer?
C.
Hope this helps. :)))
Answer:
C
Step-by-step explanation:
It can' be B because as you go right on the x-axis (forward in time), the distance upward on y (how far walked) also goes up steadily. So that is a person walking at a steady pace, no stopping.
A is interesting. It shows the person walked in the positive y-direction, stopped a while, and then went back the other way (negative y-direction).
C shows a person walking (in the positive y-direction), then stopping, then walking in the same direction some more. The probelm says they walk slower after the pause, so the slope on the second part should be less steep. I guess it is, but would it have killed them to make it a little more obvious? haha.

Answer:
YES
Criteria: SAS criterion
∆EFJ ≅ ∆HFG
Step-by-step explanation:
Side EF in ∆EFJ ≅ side HF in ∆HFG (corresponding sides)
Side FJ in ∆EFJ ≅ side FG in ∆HFG (corresponding sides)
Also,
<F in ∆EFJ ≅ <F in ∆HFG (vertical angles are congruent)
Thus, two sides and one included angle of ∆EFJ are congruent to two corresponding sides and an included angle of ∆HFG.
Therefore, by the SAS Congruence Theorem, ∆EFJ ≅ ∆HFG.

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°
m<C = 48°

jack has $20 available to buy sodas for his teammates. Each soda costs $3.50, and Jack will pay the school’s 9% sales tax for each soda. What is the maximum number of sodas Jack can buy for his teammates?
Jack can only buy 5 soda cans for his teammates after paying the tax.
What is the purpose of tax?A fundamental method for nations to produce public revenues that enable them to support investments in human capital, infrastructure, and the provision of services for citizens and businesses is through the collection of taxes and levies.
Given, Jack has $20 on hand to buy his buddies sodas. Jack will pay the 9% sales tax levied by the school for each Coke, which is $3.50.
Actual value of soda after paying the taxes = 3.50 * (1+ 9%)
Actual value of soda after paying the taxes = 3.50* (1.09) = 3.815$
Since, he has only 20$ thus,
number of soda Jack can buy = 20/ 3.815 = 5.24
Therefore, After paying the tax, Jack can only purchase 5 Coke cans for his buddies.

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)
