Answer:
8x - 7y = 56
Step-by-step explanation:
in order for lines to be parallel they need to have the same slope, the easiest way to determine if they have the same slope is to change the equations into y = mx + b form by solving for y and seeing where m=8/7
so 8x - 7y = 56
-7y = 56 - 8x
y = 56/-7 -8x/-7
y = -8 + 8/7 x

Answer:
In week 1, 69.15% of sales were 10-inch pizzas, and the remaining 30.85% were 12-inch pizzas; while in week 2, 71.09% of sales were 10-inch pizzas, and the remaining 28.91% were 12-inch pizzas.
Step-by-step explanation:
Given that a takeaway sells 10 inch pizzas and 12 inch pizzas, to determine what proportion sold were 10 inch pizzas in week 1 and what proportion sold were 10 inch in week 2, the following calculation must be performed:
Week 1 = 736 total sales
10-inch pizzas = 509
736 = 100
509 = X
509 x 100/736 = X
50,900 / 736 = X
69.15 = X
100 - 69.15 = 30.85
Thus, in week 1, 69.15% of sales were 10-inch pizzas, while the remaining 30.85% were 12-inch pizzas.
Week 2 = 1076 total sales
10-inch pizzas = 765
1076 = 100
765 = x
765 x 100/1076 = X
76500/1076 = X
71.09 = X
100 - 71.09 = 28.91
Thus, in week 2, 71.09% of sales were 10-inch pizzas, while the remaining 28.91% were 12-inch pizzas.

A factory produce bicycles at a rate of 110+0.5t^2-0.9t bicycles per week (t in weeks)
how many bicycles were produced from 8 to 2
Answer:
221
Step-by-step explanation:
Day 8 is the first day of the second week.
Day 21 is the last day of week 3.
We need to know the n umber of bicycles made from t = 1 to t = 3
The function is b(t) = 110 + 0.5t^2 - 0.9t, where t is in weeks.
We need to integrate the function with the limits of 1 to 3.
[tex] \int_{1}^{3} (110 + 0.5t^2 - 0.9t) dt [/tex]
[tex] \int_{1}^{3} (110 + \dfrac{t^2}{2} - \dfrac{9t}{10}) dt [/tex]
[tex]= 110t + \dfrac{t^3}{6} - \dfrac{9t^2}{20} \Biggr|_{1}^{3}[/tex]
[tex] = 330.45 - 109.72 [/tex]
[tex] = 220.7333 [/tex]

==========================================================
Explanation:
One shaded region is below the parabola, and the other shaded region is below the line. They both overlap outside the parabola, but under the straight line.
Since both shaded regions are below their respective boundaries, this means that we'll be using "less than" signs for each inequality. The solid boundary lines indicate "or equal to" is part of that as well.
Because of this, the answer is between A and D since both involve inequality signs that have "less than or equal to".
However, we can rule out choice D since the inequality [tex]y \le x+3[/tex] would have the boundary line [tex]y = x+3[/tex], and this boundary line has a positive slope. But notice how the red diagonal line slopes downward as we read from left to right. Therefore, the red line must have a negative slope. Luckily, choice A has one of the boundary lines as y = -x+3 to fit the description. So that's why choice A is the answer.
The system of Inequality shown by the graph given is; Option A; y ≤ x + 3 ; y ≤ x² - 3x
What is the system of inequality?
From the given inequality graph, we can see that one of the shaded regions is below the parabola while the other one is in between the bottom of the line and the parabola.
Due to the fact that both shaded regions are below their respective boundaries which are parabola and line respectively and the boundary lines are thick, it means that we will make us of the "less than or equal to" signs for each inequality.
Because of this, the answer is between A and D since both involve inequality signs that have "less than or equal to".
Thus, the correct answer is option A

PLEASE HELP ME IN ONE MINUTE
Answer: B
Step-by-step explanation:
50 points! Find the value of x. I will mark brainliest! Random answers will be reported. Thanks :)
Step-by-step explanation:
For 1st question
x = 35° + 15° {exterior angle of a triangle is equal to the sum of two opposite interior angles }
x = 50°
For second question
9x + 16° = 90° + 5x - 14°{exterior angle of a triangle is equal to the sum of two opposite interior angles }
9x - 5x = 90° - 14° - 16°
4x = 60°
x = 60° / 4
x = 15°

Please help me . What is x equal to?
1. 2 (x+3) =10
2. 2 (x+3)=9+x
3. 2(2x+1) = 3x+8
4. 2(2x+3) =X+9
Answer:
1. x = 2
2. x = 6
3. x = 6
4. x = 1
Step-by-step explanation: i think thats it
Answer:
x = 2, x = 3, x = 6, x = 1
Step-by-step explanation:
1
2(x + 3) = 10 ( divide both sides by 2 )
x + 3 = 5 ( subtract 3 from both sides )
x = 2
2
2(x + 3) = 9 + x ← distribute parenthesis on left side
2x + 6 = 9 + x ( subtract x from both sides )
x + 6 = 9 ( subtract 6 from both sides )
x = 3
3
2(2x + 1) = 3x + 8 ← distribute parenthesis on left side
4x + 2 = 3x + 8 ( subtract 3x from both sides )
x + 2 = 8 ( subtract 2 from both sides )
x = 6
4
2(2x + 3) = x + 9 ← distribute parenthesis on left side
4x + 6 = x + 9 ( subtract x from both sides )
3x + 6 = 9 ( subtract 6 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1

Suppose we select without looking one marbles de containing 5 red marbles and 7 green marbles What is the probability of selecting each of the following a) A red marble c) A purple marble b) A green marble d) Ared or a green marble a) What is the probably 3
Answer:
a) 5/12 probability of selecting a red marble.
b) 7/12 probability of selecting a green marble.
c) 0% probability of selecting a purple marble.
d) All marbles are either red or green, so 100% probability of selecting a red or a green marble
Step-by-step explanation:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
a) A red marble
5 red marbles out of 5 + 7 = 12 total marbles
So, 5/12 probability of selecting a red marble.
b) A green marble
7 green marbles out of 5 + 7 = 12 total marbles
So, 7/12 probability of selecting a green marble.
c) A purple marble
There are no purple marbles, so 0% probability of selecting a purple marble.
d) A red or a green marble
All marbles are either red or green, so 100% probability of selecting a red or a green marble

2.2 Roulette wheel: The game of roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wheel and will eventually land in a slot, where each slot has an equal chance of capturing the ball. a) You watch a roulette wheel spin 4 consecutive times and the ball lands on a red slot each time. What is the probability that the ball will land on a red slot on the next spin
Answer:
9/19
Step-by-step explanation:
Number of slots =38
red balls R = 38, black balls B = 18, green balls G = 2
we want to calculate
P( Red ball/ previous 4 spins are red) = P( red ball) [because each spin is independent to other]
= 18/38 = 9/19

what is the reciprocal of 19
Answer:
1/19
Step-by-step explanation:
In order to find the reciprocal of a number, we need to flop it over.
"Flopping over" is not the same as "changing the sign of the number"
So what does "flopping over" actually mean?
Consult the following formula:-
[tex]\sf{The~reciprocal~of~a~is\mapsto\frac{1}{a} }[/tex]
According to the formula,
