6/7 is the right answer.What type of solution represents the system x + y = 8 2x + 2y = 16
Answer:
Subtract y from both sides of the equation.
x=8−y
2x+2y=16
Replace all occurrences of x with 8−y in each equation.
16=16
x=8−y
Remove any equations from the system that are always true.
x=8−y

The line of best fit for a scatterplot is shown what is the equation of this line of best fit in slope intercept form?
(pic provided)
1. y=-6x+3/4
2.y=6x+3/4
3. y=-3/4x+6
4. y=3/4x+6
Answer:
3. y=-3/4+6
Step-by-step explanation:
The y-int is 6, so you can already cross out the first two answers. Then, you know the slope is negative because the line is going downward, so -3/4 has to be the slope bc it is negative.
Answer:
y=-3/4x+6
Step-by-step explanation:
the y/intercept is (0,6) because that is the point where the line crosses the y-axis
knowing that use the point (0,6) and (4,3) to find the slope use rise over run so it goes up 3 and right 4
using the slope intercept equation y=mx+b it is y= -3/4+6
it is negative because its going downward
hope this makes sense and helps you guys!

1. how long will it take to run 1.5 kilometres if you run a 10 metre per second
2.Steve travels at 36 kilometre per hour for 20 seconds how far does he go
Answer:
1.150 seconds or 2.5 minutes
2. 0.2km
Step-by-step explanation:
1. 1.5 x 1000=1500
1500/10=150
150/60=2.5minutes
2. 60mins = 36km -Divide both sides by 60 to get how far he would go in 1 minute/60 secs
1min/60secs=0.6km -Divide both sides by 3 to get how far he would go in 20 secs
20secs=0.2km

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the figure,
3x + 46 + 14 = 90
Now,
Simplifying.
3x + 60 = 90
Subtracting 60 on both sides.
3x = 90 - 60
3x = 30
Dividing 3 into both sides.
x = 10
Thus,
The value of x on the given figure is 10.

Write a quadratic equation for a parabola with roots at (-2, 0) & (4,0) and a y-intercept at ( 0, -16) Write your answer in factored form
9514 1404 393
Answer:
y = 2(x +2)(x -4)
Step-by-step explanation:
The y-intercept will be a constant times the product of the roots. Here, the product of the roots is (-2)(4) = -8, so the constant of interest is -16/-8 = 2. That constant is the coefficient of the leading term of the quadratic, so is a multiplier of the factored form.
y = 2(x +2)(x -4)

Answer:
x=12, SV=30
Step-by-step explanation:
Since <S is congruent to <T, you know that line TV is equal to line SV
2x+6=3x-6
subtract 2x on both sides
6=x-6
add 6 to both sides
12=x
x=12
To find SV you need to plug in x

3. If you buy a new car for $6,000 which depreciates at 4%/year,
what will the value be after 3 years?
Answer:
$5,308.42
Step-by-step explanation:
(see attached for reference)
recall that the formula for Depreciation
is given by
A = P ( 1 - r)^t,
where
A = final amount
P = principal amount = given as $6,000
r = depreciation rate = given as 4% = 0.04
t = time in years = given as 3,
Simply substitute these into the equation to get:
A = P ( 1 - r)^t
= 6000( 1 - 0.04) ^ 3
= 6000 (0.96)^3
= $5,308.42

HELP ASAP YALL- PLS
Answer: x = 4
Step-by-step explanation:
since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.
so, i redrew them next to each other, so i could compare them easily.
i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!
so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.
hope this helps! xoxo

a) AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}
b) A∩ B = { 2, 4, 6 }
c) A-B = { 8 , 10}
Step-by-step explanation:
Step(i):-
Given that the sets
U = { 1,2,3,4,5,6,7,8,9,10}
A = { 2,4,6,8,10}
B = { 1,2,3,4,5,6}
AUB = { 2,4,6,8,10} U { 1,2,3,4,5,6}
AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}
Step(ii):-
A∩ B = { 2 ,4, 6, 8,10} ∩ { 1,2,3,4,5,6} = { 2, 4, 6 }
A-B = { 2,4,6,8,10} - { 1,2,3,4,5,6} = { 8 , 10}

Answer:
A = 250
B = 75
C = 40
Step-by-step explanation:
Apparently, we're supposed to assume that the "health gained" is proportional to the "time in circle." The constant of proportionality is 100/4 = 25. This means all the numbers in the right column are 25 times those in the left column:
A = 25·10 = 250
B = 25·3 = 75
C·25 = 1000 ⇒ C = 40 . . . . . note these numbers are 10 times those in the first row

Sara and Fiona have played 53 tennis matches.
Sara has won 29 times.
Fiona won the rest.
a) Estimate the probability that Sara wins.
b) Estimate the probability that Fiona wins.
Answer: Sara = 29/53
Fiona = 24/53
Step-by-step explanation: because that amount is how much they have won and how much its out of so for example ‘i played 26 games i only won 17 and John won the rest’ the probability that i win is
17/26 and Johns would be 9/26
