Answer:
D) x =3 and x =7
Step-by-step explanation:
Step(i):-
Given function f(x) = 2x -2
g(x) = x² - 8x +19
Given that f(x) = g(x)
⇒ 2x -2 = x² - 8x +19
⇒ x² - 8x +19 -2x +2 =0
⇒ x² -10x +21 =0
Step(ii):-
The factors are x² -10x +21 =0
⇒ x² - 7x - 3x +21 =0
⇒ x( x-7) -3( x-7) =0
⇒ (x-3)(x-7) =0
x =3 and x =7

A line passes through the points (10, 6) and (5, -2). What is its equation in slope-intercept form?
Answer:
10=x
6=y
5=x
-2=y
10-5=5
6--2=8
5/8=0.625
y=mx+b
Step-by-step explanation:
The equation of a line in slope-intercept form through the points (10, 6) and (5, -2) y = (4/5)x - 6.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at
x = 0.
Given, A line passes through the points (10, 6) and (5, -2).
We know the equation of a line in slope intercept form is y = mx + b.
Where slope(m) = (- 2 - 6)/(5 - 10).
slope(m) = - 8/-10.
slope(m) = 4/5.
Now for the y-intercept,
- 2 = (4/5)×5 + b.
- 2 = 4 + b.
b = - 6.
Therefore the required line in slope-intercept form is y = (4/5)x - 6.

Mr Lee has a family of 6 people and Mrs Scarlett has a family of 4. They were given 15 kg of chocolate
when they visited a chocolate factory for work. If they decide to share it so that each family
member gets an equal amount, determine the required ratio and hence calculate how much
chocolate Mr Lee and Mrs Scarlett will each take home to their families.
Answer:
Mr Lee gets 9kg
Mrs Scarlett gets 6kg
Step-by-step explanation:
First, we have 15kg of chocolate and a total of 6 + 4 = 10 people.
We want to divide the 15kg of chocolate evenly between these 10 people, then we just need to do the quotient
15kg/10 = 1.5kg
This means that each person gets 1.5 kg of chocolate.
Now, Mr. Lee has a family of 6 people, and each one of these 6 people got 1.5 kg of chocolate, then the total amount of chocolate that Mr. Lee will bring home is 6 times 1.5kg:
6*1.5kg = 9kg
And Mrs Scarlett will get the remaining, that is:
15kg - 9kg = 6kg
Mrs Scarlett will get 6kg of chocolate.

1/3 x + 1 = 5/6 x - 3
Answer:
x=8
Step-by-step explanation:
Step 1: Subtract 5/6x from both sides.
1/3x+1−5/6x=5/6x−3−5/6x
−1/2x+1=−3
Step 2: Subtract 1 from both sides.
−1/2x+1−1=−3−1
−1/2x=−4
Step 3: Multiply both sides by 2/(-1).
(2/−1)*(−1/2x)=(2/−1)*(−4)

What is the simplified value of the exponential expression 27 1/3

Step-by-step explanation:
Marcel and Floyd are playing games at an arcade. Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games. Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining. Jorge’s work is shown below.
Let x = the number of games played.
Equation: 8.25 minus 0.25 x = 9.75 minus 0.75 x. Step 1: negative 1.50 minus 0.25 x = negative 0.75 x. Step 2: negative 1.50 = 0.50 x. Step 3: negative 3 = x.
Jorge knows his answer is incorrect because it does not make sense to have a negative number of games. What is Jorge’s error?
The variable x should represent the amount of money left.
From Step 1 to Step 2, Jorge did not add 0.25x correctly to both sides.
The equation should have sums on both sides.
From Step 2 to Step 3, Jorge should have subtracted 0.50x from both sides.
Answer:
The variable x should represent the amount of money left.

18w2(squared) - w - 39
Answer:
w = 1.5 and -1.44
Step-by-step explanation:
Given the quadratic equation 18w^2 - w - 39
Using the general formuls
w = 1 ±√1²-4(18)(-39)/2(18)
w =1 ±√1+2808/36
w =1 ±√2809/36
w = 1+53/36 and 1-53/36
w = 54/36 and -52/36
w = 1.5 and -1.44

Which number is not prime A.29 B.99 c.71 d.3
Answer:
sum like 99 becuz isz ur safest bet to get it right
Hey there!
Prime numbers are basically only approximately 2 FACTORS... 1 & that particular number
3 is PRIME because the only factors it has is 1 & 3 (so we can eliminate this as your possible answer)
29 is PRIME because it has 1 & 29 as its factors (we can eliminate this as your possible answer)
71 is PRIME because it has 1 & 71 as its factors as well! (So we can eliminate as your possible answer)
This leads Option B as your answer
Good luck on your assignment and enjoy your day!

Given:
The cost of the T.V. for Colin = £ 800.
The rate of depreciation per year = 4%
Time period = 3 years
To find:
How much will it be worth in 3 years? Give your answer to the nearest penny where appropriate.
Solution:
To solve the above-given problem, we will use the following formula:
where
A = the final value after depreciation
P = the present value
R = rate of depreciation
n = time period
Now, on substituting the given values in the formula, we get
we will round the above answer to its nearest penny where appropriate
≈ £ 708
Thus, the worth of the t.v. in 3 years will be £ 708.
8) There are 14 animals in the barn. Some
are geese and some are goats. There are
52 legs in all. Ilow many of each animal
are there?
Answer:
There are 12 goats and 2 geese.
Step-by-step explanation:
X = geese; Y = goats
Geese have 2 legs each. Goats have 4 legs each.
2x + 4y = 52
There are 14 animals
x + y = 14
x = 14 - y
(replacement)
2(14 - y) + 4y = 52
(simplify)
28 - 2y + 4y = 52
28 + 2y = 52
2y = 24
y = 12
14 - 12 = 2
x = 2
Can I get some help with this question please?
Answer:
g would be 130 because it's a vertical angle with the 130 angle. h is 50 because it has to complement the 130 angle.
K is 74 because it's a vertical angle with the 74 angle, and m is 106 because it needs to complement with k.
