Answer:
An x-y axis, also known as a cartesian coordinate system or a coordinate plane, is a two-dimensional plane of points defined uniquely by a pair of coordinates. ... The horizontal line, then, is known as the x axis and measures the distance left or right from the vertical line.

PLS HELP ASAP If -2 is added to each of the x and y intercepts of the line 3x + 2y = 6, find the new equation of the line
Answer:
3x + 2y = -4
Step-by-step explanation:
x intercept of the line occurs at y = 0
Given the equation 3x+2y = 6
3x+2(0) = 6
3x = 6
x = 2
The x intercept is at (2, 0)
Adding -2 to each axis will give (2-2, 0-2) = (0, -2)
y intercept of the line occurs at x = 0
Given the equation 3x+2y = 6
3(0)+2y = 6
2y = 6
y =3
The x intercept is at (0, 3)
Adding -2 to each axis will give (0-2, 3-2) = (-2, 1)
The new coordinates are (0, -2 and (-2, 1)
Using the point slope form of the equation y - y0 = m(x-x0)
slope m = y2-y1/x2-x1
m = 1-(-2)/-2-0
m = 1+2/-2
m = -3/2
Using m = -3/2 and (0, -2)
y - (-2) = -3/2(x-0)
y+2 = -3/2 x
2(y+2) = -3x
2y+4 = -3x
-3x-2y = 4
3x + 2y = -4
Hence the required equation is 3x + 2y = -4
pls help me i dont know how to do it

Which of the following best describes a triangle with one right angle and two congruent sides?
A right scalene triangle
B. acute scalene triangle
C. right isosceles triangle
D acute isosceles triangle
Answer:
C
Step-by-step explanation:
A is impossible. You cannot have both a right triangle and in the same triangle have an angle in it that is over 90 (that's the meaning of scalene)
B is sort of true, but only sort of. All scalene triangles have an angle over 90 and 2 acute angles.
C this is the answer to the question. It has 1 right angle and 2 equal sides. The two equal sides make it isosceles and the right angle is given.
D an acute triangle has three angles under 90 that add to 180. Not the right description.
A triangle with one right angle and two congruent sides is described as a "right isosceles triangle." (Option C)
Let's break down the terms:
1. Right Angle: A right angle is an angle that measures exactly 90 degrees.
2. Isosceles Triangle: An isosceles triangle is a triangle with at least two sides of equal length (congruent sides).
3. Right Isosceles Triangle: A right isosceles triangle is a special type of isosceles triangle where one of the angles is a right angle (90 degrees) and the other two angles are equal, each measuring 45 degrees.
In a right isosceles triangle, the two congruent sides are the legs of the right triangle, and the third side (opposite the right angle) is called the hypotenuse.
So, among the given options, the best description for a triangle with one right angle and two congruent sides is a "right isosceles triangle" (Option C).

1/2 x -7=1/3(x-12)
Answer:
= 1 8 hope this helps!!! :)
Step-by-step explanation:
1 2 ⋅ −7 = 1 3 ( − 1 2 )
1 2 − 7 = 1 3 −1 2 )
1 2 − 7 = 1 3 − 1 2 )
Multiply by 1
Combine multiplied terms into a single fraction
Multiply by 1
Add to both sides of the equation
Answer:
x = 3/2 = 1 1/2 = 1.5
Step-by-step explanation:
1/2 x -7=1/3(x-12)
Multiply 1/2 and -7 to get -7/2
-7/2 = 1/3(x-12)
Fraction -7/2 can be rewritten as -7/2 by extracting the negative sign.
- 7/2 = 1/3(x-12)
Use the distributive property to multiply 1/3 by x−12.
-7/2 = 1/3x + 1/3(-12)
Multiply 1/3 and −12 to get -12/3
-7/2 = 1/3x + -12/3
Divide −12 by 3 to get −4.
-7/2 = 1/3x + 4
Swap sides so that all variable terms are on the left hand side.
1/3x -4 = -7/2
Add 4 to both sides.
1/3x = -7/2 + 4
Convert 4 to fraction 8/2
1/3x = -7/2+8/2
Since -7/2 and 8/2 have the same denominator, add them by adding their numerators.
1/3x = -7+8/2
Add −7 and 8 to get 1.
1/3x = 1/2
Multiply both sides by 3, the reciprocal of 1/3
x = 1/2 x 3
Multiply 1/2 and 3 to get 3/2
x = 3/2

Find the equation of a line parallel to the equation y = 5x + 7 through the point (2,7).
Answer:
y = 5x + 7
Step-by-step explanation:
1. Substitue the numbers into their spots.
7 = 5(2)+b
2. Find b by simplifying
7 = 10 + b
-3 = b
3. Substitute it back in since parallel lines have the same slope.
In a right triangle, the measures of the legs are x and x + 14 and the measure of the hypotenuse is x + 16. Find the measure of x.
Answer:
[tex]x=10[/tex]
Step-by-step explanation:
We can use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
The two legs are x and (x + 14) and the hypotenuse is (x + 16). Therefore:
[tex](x)^2+(x+14)^2=(x+16)^2[/tex]
Expand:
[tex]\displaystyle x^2+(x^2+28x+196)=x^2+32x+256[/tex]
Combine like terms:
[tex]2x^2+28x+196=x^2+32x+256[/tex]
Subtract the right from the left:
[tex](2x^2+28x+196)-(x^2+32x+256)=0[/tex]
Subtract:
[tex]x^2-4x-60=0[/tex]
Factor:
[tex](x-10)(x+4)=0[/tex]
Zero Product Property:
[tex]x-10=0\text{ or } x+4=0[/tex]
Solve:
[tex]\displaystyle x = 10 \text{ or } x = -4[/tex]
The x cannot be negative since a side cannot measure -4. So, our only answer is:
[tex]x=10[/tex]
So, the legs are 10 and 24 with the hypotenuse being 26.

Choose 5 cards from a full deck of 52 cards with 13values (2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A) and 4 kinds(spade, diamond, heart, and club). Count how many possible ways to geta(a)Two-pairs: Two pairs plus another card of a different value, for example:(b)Flush: five cards of the same suitbutdifferent values, for example: (c)Full house: A three of a kind and a pair, for example: (d)Four of a kind: Four cards of the same value, for example:
Answer:
a) 182 possible ways.
b) 5148 possible ways.
c) 1378 possible ways.
d) 2899 possible ways.
Step-by-step explanation:
The order in which the cards are chosen is not important, which means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question, we have that:
There are 52 total cards, of which:
13 are spades.
13 are diamonds.
13 are hearts.
13 are clubs.
(a)Two-pairs: Two pairs plus another card of a different value, for example:
2 pairs of 2 from sets os 13.
1 other card, from a set of 26(whichever two cards were not chosen above). So
[tex]T = 2C_{13,2} + C_{26,1} = 2*\frac{13!}{2!11!} + \frac{26!}{1!25!} = 182[/tex]
So 182 possible ways.
(b)Flush: five cards of the same suit but different values, for example:
4 combinations of 5 from a set of 13(can be all spades, all diamonds, and hearts or all clubs). So
[tex]T = 4*C_{13,5} = 4*\frac{13!}{5!8!} = 5148[/tex]
So 5148 possible ways.
(c)Full house: A three of a kind and a pair, for example:
4 combinations of 3 from a set of 13(three of a kind ,c an be all possible kinds).
3 combinations of 2 from a set of 13(the pair, cant be the kind chosen for the trio, so 3 combinations). So
[tex]T = 4*C_{13,3} + 3*C_{13.2} = 4*\frac{13!}{3!10!} + 3*\frac{13!}{2!11!} = 1378[/tex]
So 1378 possible ways.
(d)Four of a kind: Four cards of the same value, for example:
4 combinations of 4 from a set of 13(four of a kind, can be all spades, all diamonds, and hearts or all clubs).
1 from the remaining 39(do not involve the kind chosen above). So
[tex]T = 4*C_{13,4} + C_{39,1} = 4*\frac{13!}{4!9!} + \frac{39!}{1!38!} = 2899[/tex]
So 2899 possible ways.

Jerry plans to begin saving money for a trip by putting $1 in a savings account the first month and then adding enough to double the amount in the account each following month. 1 I a. After he finishes contributing to the account, he will withdraw $500 to make a down payment on the trip. Create a function to show how much money will be in the account if he finishes contributing to the account after t months.
Answer:
A=2*(t-1)-500
Step-by-step explanation:
I did it on study island.
Function representing the amount of money as per given condition in the account after [tex]t[/tex] months is equals to [tex]A= 2^{t-1} -500[/tex].
What is function?" Function is defined as relation between variables is such that for each input value there exist one and only one output."
According to the question,
Given,
Amount in the account
Frist month [tex]= \$1[/tex]
[tex]= 2^{1-1}[/tex]
As per given condition,
second month [tex]= \$2[/tex]
[tex]= 2^{2-1}[/tex]
Third month [tex]= \$4[/tex]
[tex]= 2^{3-1}[/tex]
.........
Amount in the account in [tex]'t'[/tex] months [tex]= 2^{t-1}[/tex]
Jerry withdraw [tex]\$500[/tex] to make a down payment on the trip.
[tex]'A'[/tex] represents the total amount left in the account
Required function as per given condition,
[tex]A = 2^{t-1} -500[/tex]
Hence, function representing the amount of money as per given condition in the account after [tex]t[/tex] months is equals to [tex]A= 2^{t-1} -500[/tex].
