through: (1, 2), slope = 2
Answer:
y=2x+2
Step-by-step explanation:
Answer: y = 2x
Step-by-step explanation:
y=mx+b
m is the slope. so if the slope is 2 we can fill in 2 for m.
y = 2x + b
now we are going to plug in the point they gave us (1, 2) to find b.
1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.
2 = 2(1) + b
2 = 2 + b
b = 0
so our equation is y = 2x + 0, or y = 2x

Solve the system of equations. How many 10 oz. boxes were sold?
6

15
9514 1404 393
Answer:
15
Step-by-step explanation:
We see that x represents the number of 10-oz boxes sold. Then y=24-x is the number of 16-oz boxes sold. Substituting for y in the second equation gives ...
3.50x +5.00(24 -x) = 97.50
-1.50x +120 = 97.50
22.50 = 1.50x . . . . . . . add 1.50x -97.50
15 = x . . . . . . . . . . . . . . divide by 1.50

A line with a slope of -7 passes through the points (-8, 7) and (-7, k). What is the value of
K?
Answer:
k = 0
Step-by-step explanation:
On the graph, the second point would be at (-7,0)
Answer:
k = 0
Step-by-step explanation:
We can find the answer to this question by using the slope equation:
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's define some variables:
[tex]\frac{k - 7}{-7-(-8)} = \frac{k-7}{1} = k- 7[/tex]
We know the slope is -7 so we can put k-7 equal to it and solve
[tex]k-7 = -7\\k = 0[/tex]
We find that k is equal to 0.
I hope this helps!!

Answer:
9.42m
Step-by-step explanation:
You have to find the circumference using C=2πR. We know that the radius =4 meters so then we can insert it into the formula to get the circumference which equals 8π. Then we divide 24m² by 8πm and get 9.42m.
In the figure above, AB = AD, BC = CD, BE = 2, BC = 4, and AC = 10. What is the area of triangle ABD?
The properties of items in a question can be used to simplify the solution to the questions
The area of triangle ΔABD is 20 - 4·√3
The reason the above value for the area of ΔABD is correct is as follows:
The given parameters are;
AB = AD, BC = CD, BE = 2, BC = 4, AC = 10
Given that AB = AD, and BC = CD, we have that the figure ABCD is a kite
∴ AC is perpendicular to BD by properties of the diagonals of a kite
ΔBCE is a right triangle
By Pythagoras' theorem, [tex]\overline{CE}[/tex]² = [tex]\overline{BC}[/tex]² - [tex]\overline{BE}[/tex]²
Which gives;
[tex]\overline{CE}[/tex]² = 4² - 2² = 12
[tex]\overline{CE}[/tex] = 2·√3
Given that AC is the perpendicular bisector of BD, by the properties of a kite, we have;
BD = BE + DE, where BE = DE definition of bisected line
∴ BD = BE + BE = 2·BE
Area of a triangle = (1/2) × Base length × Height
AE = The altitude (height) of the ΔABD = AC - CE
∴ AE = 10 - 2·√3
BD = The base length of ΔABD = 2·BE (Length of BE = 2)
∴ BD = 2 × 2 = 4
The area of triangle ΔABD = (1/2) × BD × AE
∴ The area of triangle ΔABD = (1/2) × 4 × (10 - 2·√3) = 20 - 4·√3
The area of triangle ΔABD = 20 - 4·√3

What best describes the relationship between line 6x - 2y = 1 and the line x + 3y = 12?
is it parallel, perpendicular, or neither?
Both the lines are perpendicular lines.
What is Equation of line?The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation of lines are,
⇒ 6x - 2y = 1 and x + 3y = 12.
Now,
Since, The equation of lines are,
⇒ 6x - 2y = 1 and x + 3y = 12.
Hence, Find the slopes of the lines as;
⇒ 6x - 2y = 1
⇒ 2y = 6x - 1
⇒ y = 3x - 1/2
⇒ m₁ = dy/dx = 3
And, From second line,
⇒ x + 3y = 12.
⇒ 3y = - x + 12
⇒ y = - 1/3x + 4
⇒ m₂ = dy/dx = - 1/3
Clearly, We get;
⇒ m₁ m₂ = 3 × - 1/3
= - 1
Thus, Both the lines are perpendicular lines.

75 POINTS AND BRAINLIEST IF ITS CORRECT!!!
Answer: The first and last table.
As the x increases by 2, the y goes down by 1, so both tables have the same rate of change which means they are the same function.
Tables 1 and 5 are equal.
Given are 5 tables in x and y with two values each.
We are to find out which two represent the same function.
As for every function, two points are given.
Let us compare the slopes of each function.
Slope=change in y coordinate/change in x coordinate
Table Slope
I -0.5
2 -0.5
3 -0.5
4 1
5 -0.5
Table 4 is eliminated now.
Though slopes are the same for 1 and 2,f(4) =8 and 5 different . Hence I and II cannot be the same. Similarly for 2 different values are there in table 3,4,5. Hence 3,4,5 cannot be pairwise equal.
We find that table I and table 5 have the same slope. Also when pairwise taken, (4,8) and (2,9) slope = -0.5
So table I = table 5

Amelia is making a cookie recipe that requires 4 cups of sugar for every 12 cups of flour. Amelia only has 9 cups of flour. She concludes that she will only need 3 cups of sugar Is Amelia correct? Why or why not?
A Amelia is correct. She needs 3 cups of sugar because the ratio 3:9 is equivalent to 4:12.
B Amelia is correct. One-quarter the amount of sugar is needed because only one-quarter of the recipe will be made.
C Amelia is incorrect. The number of cups of sugar must be reduced by 3 because the number of cups of flour is reduced by 3.
D Amelia is incorrect. She needs 4 cups of sugar because decreasing the number of cups of flour by 3 requires increasing the number of cups of sugar by 3.
Answer:
B
Step-by-step explanation:
Because if you will divide the ratio 4:12 by three- we will get a ratio 1:3. Then we need the last 3 in the ratio 1:3 become a 9. For this we need to multiply it by 3= 1:3 *3= 3:9. This is only 3/4 of whole of recipe.
Answer: Choice A)
Amelia is correct. She needs 3 cups of sugar because the ratio 3:9 is equivalent to 4:12
=======================================================
Explanation:
It might help to think of the ratio 4:12 as the fraction 4/12. Dividing both parts by 4 leads to 1/3.
Similarly, the ratio 3:9 becomes 3/9 which reduces to 1/3.
This shows that 4/12 = 3/9, so the ratios 4:12 and 3:9 are the same.
------------
Another way to show two fractions are equal is to do the steps below
4/12 = 3/9
4*9 = 12*3 ... cross multiply
36 = 36
Since the last equation is true, the first equation must be true.
-------------
Here's another way to see Amelia is correct.
So we know that 4 cups of sugar go with 12 cups of flour. This forms the fraction 4/12.
We also know that she has 9 cups of flour. Let's say we don't know how much sugar she needs, so we'll call this x. We have x cups of sugar go with 9 cups of flour. This forms the fraction x/9.
Equate the two fractions and solve for x
4/12 = x/9
9*4 = 12*x ... cross multiply
36 = 12x
12x = 36
x = 36/12 ... divide both sides by 12
x = 3
She needs 3 cups of sugar
