Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = -7x + 6
y = -10x
Step 2: Solve for x
Substitution
Substitute in y: -10x = -7x + 6Add 10x to both sides: 0 = 3x + 6Isolate x term: -6 = 3xIsolate x: -2 = xRewrite: x = -2Step 3: Solve for y
Define equation: y = -10xSubstitute in x: y = -10(-2)Multiply: y = 20Answer:
x = -2
y = 20
Step-by-step explanation:
y = -7x + 6
y = -10x
y = -10x
-7x + 6 = -10x
3x = -6
x = -2
y = -7x + 6
y = -7 ( -2 ) + 6
y = 14 + 6
y = 20

The coordinates of the vertices of △DEF are D (1, 2) , E (2, 0) , and F (−1, 0) .
The coordinates of the vertices of △D′E′F′ are D′ (1, −4) , E′(2, −2) , and F′ (−1, −2) .
What is the sequence of transformations that maps △DEF to △D′E′F′ ?
Drag and drop the answers into the boxes to correctly complete the statement.
A sequence of transformations that maps △DEF to △D′E′F′ is a _____ followed by a ________.
Answer:
Step-by-step explanation:
△D′E′F′ is reflection of △DEF across y = - 1.
The transformation of the △DEF to △D′E′F′ is as follows; The △D′E′F′ is a reflection of △DEF across y = - 1.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
As per the given triangle △DEF with vertices D (1, 2) , E (2, 0) , and F (−1, 0) .
The plot of the above triangle has been plotted below,
As per the given triangle △D′E′F with vertices D′ (1, −4) , E′(2, −2) , and F′ (−1, −2) .
The plot of the above triangle has been plotted below,
It is clear that △DEF is reflected and how much is reflected can be known by making equal distance.
Since it equals apart from y = -1 thus it will be a reflection of y = -1.
Hence "The transformation of the △DEF to △D′E′F′ is as follows; The △D′E′F′ is a reflection of △DEF across y = - 1".

Step-by-step explanation:
train a travels at 12.5 m/s and will arrive at 100m in 7s.
train b arrives at the same distance, 100m, in 4s. so that means train b is going at 100m/4s and then simplify that

Answer:
10 years
Step-by-step explanation:
We want to find the value of t when R = 8.2. Equivalently, we want to find t when ...
0.001(-t^3 +16t^2 +900t -1400) -8.2 = 0
A graphing calculator is useful for finding real solutions to this equation. The attachment shows the store was in business 10 years when revenue reached 8.2 million.

James drives a distance of 320 miles in 4 hours. What was his speed?
A. 80 mi/min
B. 80 mi/hr²
C. 80 km/hr
D. 80 mi/hr
Answer: D
Step-by-step explanation:
because 320/4 = 80 mi/hr because it can not km or min and hr^2 would not make any sense
James will cover 320 miles in 4 hours with the speed of 80 miles/hour.
What is speed?
Speed is the distance traveled per unit of time. The speed is given by distance/time.
What will be the speed of James?The distance travelled by James is 320 miles in 4 hours.
Divide distance by time to get the speed of James.
320/4=80.
The unit of distance was miles and of time was hour so the unit of speed will be miles/hour.
Therefore, the speed of James will be 80 miles/hour which is option D.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 400 feet. Determine the flag's length and width if the length is 80 feet greater than the width.
Answer:
Length-140 ft
Width-60 ft
Step-by-step explanation:
I tried many different combinations
Answer: 120 ft
Step-by-step explanation:
So the equation we start off with is
2l+2w=400 in this situation
Since we know one length is 80,
2l would be 160.
So now we have 160+2w=400
Now we can use the perimeter to find the width now that we know the 2l.
400-160=2w
2w=240
240÷2
W=120
Mke y the subject of the formula.
w=x^2-2yz
Answer:
W = x^2 - 2yz / - w
0 = x^2 - 2yz - w / +2yz
2yz = x^2 - w // 2z
y = (x^2 -w ) / 2z
So correct answer is D
