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
PLS HELP! DUE IN 10 MINS PLS!!!!!!!!!!!!!!!
Answer:
25 metres per second
Step-by-step explanation:
just divide 100 by 4 and you will get the answer.☺️☺️
Answer:
25 m/s
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
therefore train b is moving at 25m/s
Which of the following is the correct representation of permutation?
rPn
P (n,r)
C(n, r)
nCr
The Correct option is (b) i.e. P (n , r)
What is Permutation?
A Permutation is the number of way a set can be arranged or the number of ways things can be arranged.With a permutation, the order of numbers matters.The main types of permutations are those with repetition and those without, although other less common types include permutations with multi-sets and other permutation.P (n , r) = n! ÷(n-r)!
where,
n = total items in the set;r = items taken for the permutation;"!" denotes taking the factorial.The Correct option is (b) i.e. P (n , r)

A discount sports store has been open for 17 years. For this time period, the store’s annual revenue, R (in millions of dollars), can be modeled by the function
(picture) where t represents the number of years since the store opened. Determine the number of years the store was in business when the revenue amount reached $8.2 million.
9514 1404 393
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.

It was only when she heared the footsteps of her mother entering the house that it came back to her mind. She quickly scatters and finds her way to her mum while pulling on her boots. Her mother starts to remind her about the chores when to her suprise she sees a unsual camera perched right on top of a cows head in the distance. Lucy mothers questions her which Leads to Lucy's explaination of using the camera to record the goats "skateboarding".To her mother dissappoint that wasn't the only exprirment Lucy had run in the course of the time she was out of the house. She also glances towards the sink overflowing with mud which Lucy's termed as "immaculate mud".

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".

3x - 4y = 36
5x + 2y = 8 ( multiply all by two )
3x - 4y = 36
10x + 4y = 16
13x = 52
