Answer:
i hope you meant "y" instead of "t" because that would make so much more sense. all you have to do with this is replace "y" in the equation with "x + 3" (this makes the equation x = 3[x + 3] - 2). now, you multiply and combine the like-terms (making x = 3x + 7). you now continue by subtracting 3x from both sides of the equation to make -2x = 7 and dividing to make x = -3.5
Step-by-step explanation:
x = 3(x + 3) - 2
x = 3x + 9 - 2
x = 3x + 7
-2x = 7
x = -3.5

Find the slope of the line through the points (-4, 3) and (3, 5)
Answer: 2/7
Step-by-step explanation:
Slope is ∆y/∆x. ∆ is read as "delta". The "delta" sign means "the difference between". So that means the difference between the y-coordinates divided by the x-coordinates gives us slope. Therefore, using the coordinates, 5-3 gives us the rise. And 3-(-4) gives us the run. Rise/Run is also equivalent to the slope. Thus, our final answer is 2/7.

Answer:
See images
Step-by-step explanation:
Either one should work.
An isosceles triangle is a triangle where two angles are the same & the third angle is the supplement of their sum.
If you wanted the matching angles to be 70 & 70, your final angle would be 40 because:
70 + 70 = 140
180 - 140 = 40
If you wanted the supplement angle to be 70, your matching angles would be 55 & 55 because:
180 - 70 = 110
110 / 2 = 55
Hope this helped. :)

500/2000 = 0.25
Therefore 500 students would vote for Jen.
A recipe calls for 2,000 grams of sweet potatoes. Which expression can be used to find how many kilograms of sweet potatoes are needed?
Answer:
2 kilograms of sweet potato
Step-by-step explanation:
1 kilogram = 1000 grams.
So, to find how many kilograms there are divide by 1,000
2,000 ÷ 1,000 = 2
So, there are 2 kilograms needed.

Inverse tangent is used to find a missing angle measure when we are given the___ and the ____.
a. opposite side; adjacent side
b. same side; other side
c. adjacent side; hypotenuse
d. opposite side; hypotenuse
We can infer here that the inverse tangent is used to find a missing angle measure when we are given the opposite side and the adjacent side.
What is inverse tangent?An inverse tangent is known to be the formula that is used to find an angle of a right-angled triangle when certain sides are given. This is true when opposite and adjacent sides are given.
Thus, to find an angle using inverse tangent, we will have: θ = tan-1[ (opposite side) / (adjacent side) ].

Stephan has a piece of wood that measures 18 inches long and 12 inches wide. He wants to make a tray with sides 2 inches high. Maurice says that he can make a tray that has a base measuring 10 1/2 inches by 10 1/2 inches. Is he correct? Use the drop-down menus to explain your answer.
Answer:
i. No, Maurice statement is wrong.
ii. Stephan does not have sufficient pieces of wood to make the tray because the square inches required is more than what he has.
Step-by-step explanation:
Stephan's piece of wood measures; 18 inches in length and 12 inches in width.
Since the piece of wood has a shape of a rectangle,
the area of the piece of wood = length × width
= 18 × 12
= 216 square inches
According to Maurice's statement, he could make a tray that has a base of 1012 inches by 1012 inches.
The base has the shape of a square, so that;
the area of the base = length × width =
= 1012 ×1012
= 1024144 squared inches
This shows that Stephan does not have sufficient wood to make the tray because the square inches required is more than what he has. and 16 more users found this answer helpful

the point here is that the bulk of the data was 11-14, but because there were less people down lower, the mean of the data is at 13, and the data is bigger (skewed) to the left.

Fiona deposited $900 in the bank over 2 years. She earned $60 in
simple interest at the end of the 2 years. What was the annual
interest rate?
If Fiona deposited $900 in the bank over 2 years. She earned $60 in
simple interest at the end of the 2 years then 3.33% is the annual
interest rate.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Fiona deposited $900 in the bank over 2 years.
She earned $60 in simple interest at the end of the 2 years.
We have to find the annual interest rate
I=PRT
60=900×2×T
60=1800T
Divide both sides by 1800
T=3.33%
Hence, the annual interest rate is 3.33%

Answer:
15Step-by-step explanation:
Use Pythagorean:
x² + 2.75² = 15.25²x² = 15.25² - 2.75²x² = 225x = √225x = 15Step-by-step explanation:

1. A box without a top is to be made from a rectangular piece of cardboard, with dimensions 3 in. b)
in., by cutting out square corners with side length x and folding up the sides.
Answer:
a) The volume of the box is represented by [tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex].
b) A side length of 0.653 inches leads to the maximum volume of the box: 6.299 inches.
Step-by-step explanation:
a) The volume of the box ([tex]V[/tex]), in cubic inches, is modelled by the equation for the cuboid:
[tex]V = (3-2\cdot x) \cdot (7-2\cdot x) \cdot x[/tex] (1)
Where [tex]x[/tex] is the side length of the cutted square corners, in inches.
[tex]V = (21 - 20\cdot x + 4\cdot x^{2})\cdot x[/tex]
[tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex]
The volume of the box is represented by [tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex].
b) The method consist in graphing the polynomial and looking for a relative maximum. We graph the equation found in a) by means of a graphic tool. We present the outcome in the image attached below. According to this, a side length of 0.653 inches leads to the maximum volume of the box: 6.299 inches.

The Vertical Angles Theorem states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruent. This means that 48° should equal (7x+13)°, because they're vertical angles. The equation should appear as 48=7x+13. Subtract 13 on both sides to get. 35=7x. Divide 7 on both sides to result with x=5.
