the slope of the line is below 2. use the coordinates of the labeled point to find a point-slope equation of the line.
Answers
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (1, 9) , thus
y - 9 = 2(x - 1) → C

In a proportional relationship, one variable is always a constant value by the other. That constant is known as the constant of proportionality.
A proportional relationship between the variables x and y is written as:;
y=k.x
For the given problem, y represents the cups of water needed for making x loaves of French bread.
We know that Marley used y=7 cups of water to make x=4 loaves of French bread. Substituting into the equation;
7=k.4
Solving for k:
k = 7/4
The equation to model the problem;

Assume that y varies inversely with x. If y=1/3 when x=1/2, find y when x=1/4.
Answers
Answer:
y = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = [tex]\frac{1}{3}[/tex] when x = [tex]\frac{1}{2}[/tex] , thus
[tex]\frac{1}{3}[/tex] = [tex]\frac{k}{\frac{1}{2} }[/tex] = 2k ( divide both sides by 2 )
k = [tex]\frac{1}{6}[/tex]
y = [tex]\frac{1}{6x}[/tex] ← equation of variation
When x = [tex]\frac{1}{4}[/tex] , then
y = [tex]\frac{1}{6(\frac{1}{4}) }[/tex] = [tex]\frac{1}{\frac{3}{2} }[/tex] = [tex]\frac{2}{3}[/tex]

what is the solutions by solving by quadratic equations
Answers
Answer:
x = - 4
Step-by-step explanation:
Given
- x² - 8x - 16 = 0 ( multiply through by - 1 to clear the leading negative )
x² + 8x + 16 = 0 ← this is a perfect square
(x + 4)² = 0 ( take the square root of both sides )
x + 4 = 0 ( subtract 4 from both sides )
x = - 4

PLZ ANSWER QUICK:
The graph shows two lines, A and B:
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 3, 0, and the ordered pair 0, 6. Another straight line labeled B joins the ordered pair 0, 0, and the ordered pair 5, 5.
Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?
0, 6) is the solution to both lines A and B.
(0, 6) is the solution to line B but not to line A.
(2, 2) is the solution to both lines A and B.
(2, 2) is the solution to line A but not to line B.
Answers
Answer: Choice D
(2,2) is the solution to line A, but not to line B
==========================================================
Explanation:
Let's find the equation of line A
First we need the slope
m = (y2-y1)/(x2-x1)
m = (6-0)/(0-3)
m = 6/(-3)
m = -2
Since the point (0,6) is on line A, we know b = 6 is the y intercept.
The equation of line A is y = -2x+6.
-----------------------------
Let's find the equation for line B
So we need the slope
m = (y2-y1)/(x2-x1)
m = (5-0)/(5-0)
m = 5/5
m = 1
The y intercept is b = 0 since the line goes through (0,0)
The equation of line B is y = 5x+0 which is the same as y = 5x.
------------------------------
Our system of equations is
[tex]\begin{cases}y = -2x+6\\y = 5x\end{cases}[/tex]
We can see that plugging x = 0 into line A's equation leads to y = 6. So (0,6) is on line A. However, the point (0,6) is not on line B because plugging x = 0 leads to y = 0.
This allows us to rule out choices A and B.
--------------------------------
Let's see what happens when we plug in x = 2 to line A
y = -2x+6
y = -2*2+6
y = -4+6
y = 2
The point (2,2) is on line A
Now let's do the same for line B
y = 5x
y = 5*2
y = 10
The point (2,10) is on line B meaning that (2,2) is not on line B.
We can rule out choice C and conclude that choice D is the final answer.
Side note: Choice D should read "(2,2) is a solution" instead of "(2,2) is the solution" since there are infinitely many solutions on any given line. So another solution for example would be (0,6).

find cube root of 175616 ??
i will mark u as brainlist if u would give a correct answer with Explanation
Answers
Answer:
56
Step-by-step explanation:
Cube root of 175616 by prime factorization method is 56
Solution:
To find cube root of 175616 by prime factorization method
A number that must be multiplied by itself three times to equal a given number is called cube root
Prime factorization method:
Prime factorization is a number written as the product of all its prime factors.
In order of finding cube root by prime factorization we use the following steps:
Step I : Obtain the given number
Step II : Resolve it into prime factors.
Step III : Group the factors in 3 in such a way that each number of the group is same
Step IV : Take one factor from each group
Step V : Find the product of the factors obtained in step IV. This product is the required cube root
Prime factorization of 175616:
\text{ prime factors of 175616 } = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 7 \times 7 \times 7 prime factors of 175616 =2×2×2×2×2×2×2×2×2×7×7×7
Thus we get,
\sqrt[3]{175616} = \sqrt[3]{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 7 \times 7 \times 7}

175616
=

2×2×2×2×2×2×2×2×2×7×7×7
Make the groups of 3 of equal numbers
\sqrt[3]{175616} = \sqrt[3]{2 \times 2 \times 2} \times \sqrt[3]{2 \times 2 \times 2 \times } \times \sqrt[3]{2 \times 2 \times 2} \times \sqrt[3]{7 \times 7 \times 7}

So there are 4 equal groups. So from that group take one factor out
\sqrt[3]{175616} = 2 \times 2 \times 2 \times 7 = 56
3
175616
=2×2×2×7=56
Thus Cube root of 175616 by prime factorization method is 56
