Rewrite the point-slope equation in slope-intercept form: y - 3 = 2(x + 4)
A) y = 2x + 5C
B) y = 2x + 7
C) y = 2x + 9
D) y = 2x + 11
Answer:
y = 2x + 11
Step-by-step explanation:
y - 3 = 2(x + 4)
y - 3 = 2*x + 2*4
y -3 = 2x + 8
y = 2x + 8 +3
y = 2x + 11

Find the first term of a sequence x+1,2x-18,2x-1,if this sequence is an arithmetic progression
Answer:
a₁ = 37
Step-by-step explanation:
In an arithmetic progression the common difference d is
d = a₂ - a₁ = a₃ - a₂ , that is
2x - 18 - (x + 1) = 2x - 1 - (2x - 18) ← distribute and simplify both sides
2x - 18 - x - 1 = 2x - 1 - 2x + 18
x - 19 = 17 ( add 19 to both sides )
x = 36
Thus
a₁ = x + 1 = 36 + 1 = 37

Genise is making cookies. She needs 1 2/3 cups of flour for one batch, but she wants to make 2 1/2batches. Write an equation that can be used to find how many cups of flour Genise will need. I need help with my math quiz thanks
Answer:
(1 2 ÷ 3) (2 1 ÷ 2) = x
Step-by-step explanation:
The equation is
Let us assume x be the amount of flour she will need in cups.
Now
1 2 ÷ 3 becomes 5 ÷ 3
2 1 ÷ 3 becomes 5 ÷ 2
Now multiply each number
(5 ÷ 3)(5 ÷ 2) = x
25 ÷ 6 = x
Hence, (1 2 ÷ 3) (2 1 ÷ 2) = x this would be the equation

simplest form of ratio 24:36:60
Answer:
2:3:5
Step-by-step explanation:
24:36:60
1) Find the greatest common factor
24 ⇒ 1, 2, 3, 4, 6, 8, 12, 24
36 ⇒ 1, 2, 3, 4, 6, 9, 12, 18, 36
60 ⇒ 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Therefore, the greatest common factor is 12.
2) Divide all values by 12
24 ÷ 12 = 2
36 ÷ 12 = 3
60 ÷ 12 = 5
Therefore, the simplified form of the ratio is 2:3:5.

Maria buys 4 1/5 pounds of plums. The total cost after using the coupon for 55 cents off her entire purchase is 3.23$. If c represents the cost of the plums in dollars per pound, what equation could represent the situation?
$3.23 = 4 1/5c - .55
4 1/5c = the pounds of plums, and the cost of each pound. - .55 represents subtracting the coupon.

2. Regroup terms
[tex]-3b=-12[/tex]
3. Divide both sides by -3.
[tex]b=\frac{-12}{-3}[/tex]

The figure below is reflected over y-axis and then rotated 180° counterclockwise.
What are the coordinates of the image of point Y after these transformations?
Answer:
The coordinates of point y after the transformation is (-6,5)
Step-by-step explanation:
Firstly , we need to get the coordinates of the point y before the transformation
The coordinates are
(-6,-5)
By reflecting over the y-axis, we have the following change;
(x,y) becomes (-x,y)
So we have;
(6,-5)
Then we are to rotate at an angle of 180 degrees counterclockwise
The operation here will be;
(x,y) to (-x,-y)
So we have;
(6,-5) to (-6,5)
A triangle has sides with lengths of 44 meters, 55 meters, and 77 meters. Is it a right triangle?
Answer:
no it is not a right triangle because the lengths add up to 176 and a right triangle should add up to 190.
Step-by-step explanation:
The side measures of the triangle does not form a right triangle.
What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
The side lengths of the triangle are 44 meters, 55 meters, 77 meters.
For the triangle to be a right triangle, one interior angle should be 90°.
Based on the sides, by Pythagoras theorem,
Square of long side = sum of square of other two sides
⇒ [tex]77^{2}=44^{2} +55^{2}[/tex]
⇒ [tex]5929=1936+3025[/tex]
⇒ [tex]5929\neq 4961[/tex]
Hence we can conclude that the side measures of the triangle does not form a right triangle.

Find the length of side a.
Answer:
C. 5
Step-by-step explanation:
Keeping in mind that this is a right triangle, to find the length of side a, we can use the Pythagorean Theorem.
Remember, the Pythagorean Theorem is:
a² + b² = c²
where a and b are the legs of the right triangle and c is the hypotenuse.
As we can see in the image, a is one of the two legs of the right triangle. 13 is the hypotenuse and 12 is another leg. Plugging into the Pythagorean Theorem, we get:
a² + 12² = 13²
Now we solve for a.
a² + 144 = 169
Subtract 144 from both sides.
a² = 169 - 144
a² = 25
Take the square root of both sides.
a = √25
a = 5
So the length of side a would be 5.
The answer would be C. 5.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer: C. 5
Step-by-step explanation:
We'll use the Pythagorean Theorem to find the missing side.
a^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
(simplify)
[tex]a^2 = \sqrt{25}[/tex]
a = 5

Shaan’s math homework scores for the semester are 90, 85, 98, 60, 84, and 78. Shaan’s teacher said she would drop the lowest homework score when calculating grades. How does the mean of Shaan’s actual math scores compare to the mean of the scores when the lowest one is dropped?
a. The relationship cannot be determined.
b. The final mean is the same as the original.
c. The final mean is lower than the original.
d. The final mean is higher than the original.
Answer:
The final mean is higher
Step-by-step explanation:
The mean of all the scores = [tex]\frac{90 + 85 + 98 + 60 + 84 + 78}{6\\} = \frac{495}{6} = 82.5\\[/tex]
The mean of the scores with the 60 dropped = [tex]\frac{435}{5} = 87[/tex]
The final mean is higher
That will always happen when you drop the lowest score. I worked it out for you so that you would see that it happened in your case.
