Translate(1.3, -1)
Scale Factor: 2/3
Step-by-step explanation:
First, perform a dilation about the origin. This will make the original shape smaller.
From the given diagram, we can see that R'S' is 10 units long. RS is 15 units long. Using this information, we can create this ratio.
[tex]\frac{10}{15}[/tex]
This means that Triangle R'S'T' is 2/3 of Triangle RST. Construct lines from the origin (the center of dilation) to each point on the original triangle. Then, find two thirds of that line. The new point will be the new y-coordinate.
The new coordinates will (approx.) be:
R = (-2, 4.7)
S = (-2, -5.3)
Only two coordinates are necessary to perform this translation. As per the graph, this triangle must shift approximately 1.3 units up and 1 unit to the left. Thus, the final translation is:

If Zoe already has $80 and can save an additional $6 per week using money from her after school job then the total amount of money that Zoe saved after 6 week of saving is $116 and
the expression that represent amount of money Zoe would have saved in w weeks is [tex]80+6w[/tex] .
The amount that Zoe already saved = $80 ;
the amount that she can additionally save is = $6 per week ,
the amount of money that can be saved after 6 weeks can be written as :
[tex]Amount = \$80+(Amount Saved Per Week)\times(Number Of Weeks)[/tex]
Amount = [tex]80+6\times6[/tex]
= [tex]80+36[/tex]
= $116
and the expression for w weeks will be = [tex]80+6\times w[/tex]

Answer:
b
Step-by-step explanation:
I think number B is the answer. because the square becomes root when it crosses the = . So, the answer is B
Answer:
b. ±√60
Step-by-step explanation:
You want to know the solution to x² = 60.
SolutionIn general, the process of solving for a variable's value requires you to "undo" what is done to the variable. This generally means you use inverse operations. The inverse of the squaring operation is the square root operation.
Taking the square root of both sides, we get ...
√(x²) = √60
|x| = √60 . . . . . . simplify the left side
x = ±√60 . . . . . . . write the equivalent without the absolute value bars
__
Additional comment
As with any operation performed on an equation, it must be done to both sides of the equal sign.
You will get a ±(radical) result whenever you take an even-index root: square root, fourth root, sixth root, and so on. Odd-index roots will have the same sign as the value under the radical.
√64 = ±8
∛64 = 4; ∛-64 = -4

what is the area and perimeter of 29 yd and 72 yd
Answer:

Step-by-step explanation:
Since it's a rectangle, both small sides are going to be the same, and both long sides are going to be the same. So for perimeter add up 29+72+29+72 to equal 202. For area you just multiply 29 times 72:)

Answer:
y = 2x + 10
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, 10) ← 2 points on the line
m = [tex]\frac{10-0}{0-(-5)}[/tex] = [tex]\frac{10}{0+5}[/tex] = [tex]\frac{10}{5}[/tex] = 2
the line crosses the y- axis at (0, 10 ) ⇒ c = 10
y = 2x + 10 ← equation of line

The polynomial in intercept form so that P(x)=0 has the given roots is, x^2 - √3x - 2x + 2√3 = 0.
What is polynomial?
A polynomial is an expression in mathematics that only uses the operations of addition, subtraction, multiplication, and powers of positive-integer variables. It consists of indeterminates and coefficients. The polynomial x^2 4x + 7 is an illustration of one with a single indeterminate x.
We have to find the polynomial in intercept form so that P(x)=0 has the roots 2 and √3.
Let 2 and √3 are the roots of the polynomial so,
x = 2, x = √3
⇒ x - 2 = 0, x - √3 = 0
⇒ (x - 2)(x - √3) = 0
x^2 - √3x - 2x + 2√3 = 0
Hence, the polynomial in intercept form so that P(x)=0 has the given roots is, x^2 - √3x - 2x + 2√3 = 0.

Jackson is going to invest $33,000 and leave it in an account for 20 years. Assuming the interest is compounded continuously, what interest rate, to the nearest tenth of a percent, would be required in order for Jackson to end up with $133,000?
Answer:
Rate = 7.0% per year
Step-by-step explanation:
Formula: rate = In(A/P)/t
I = interest
n = compound, in this case continuous
A = Total amount ($133,000)
P = Principal ($33,000)
t = time (20 years)
Plug in the values and solve:
rate = In(133000/33000)/20
rate = 0.06969
Convert to percentage:
rate = 6.969%
Round to the nearest tenth of a percent:
rate = 7.0%
write an equation that represents the relationship between x and y shown in the table
An equation that represents the relationship between x and y shown in the table is y = 1.5x.
How to write an equation?In order to write an equation that represents the relationship between x and y shown in the table, we would have to find the slope from the table and then write the required equation based on the data points by using the point-slope form.
Mathematically, the point-slope form of a line is given by this mathematical equation:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y are the points.By substituting the given parameters into the point-slope formula, an equation for the data points contained in this table is given by;
y - y₁ = m(x - x₁)
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 21 = (96 - 21)/(64 - 14)(x - 14)
y - 21 = 75/50(x - 14)
y - 21 = 1.5(x - 14)
y = 1.5x - 21 + 21
y = 1.5x

The standard form of the polynomial -n²(n² + 5n + 6) is -n⁴ - 5n³ - 6n².
How to represent polynomial in standard form?Polynomials are algebraic expressions that consist of variables and coefficients.
The standard form of a polynomial is expressed by writing the highest degree of terms first then the next degree and so on.
Hence, let's represent the polynomial in standard form as follows:
-n²(n² + 5n + 6)
Open the brackets
-n²(n² + 5n + 6) = -n⁴ - 5n³ - 6n²
Hence,
-n²(n² + 5n + 6) = -n⁴ - 5n³ - 6n²

a shopper purchased 8 t-shirts and 5 pairs of pants for $220. the next day, he purchased 5 t-shirts and 1 pair of pants for $112.How much does each t shirt and each pair of pants cost?
Answer:
Step-by-step explanation:
Let the costs of 1 t - shirt and 1 pair of pants be 'x' and 'y' respectively then:
Case 1 --> 8x + 5y = 220 ----------(1)
Case 2 --> 5x + y = 112 ----------(2)
Multiplying equation (2) by 5:
8x + 5y = 220
25x + 5y = 560 ------(3)
Subtracting equation (1) from equation (3) we get :
17x = 340
x = 20
Putting x in (2):
5 x 20 + y = 112
y = 12
therefore, cost of each t-shirt is 20 rupees and the cost of each pair of pants is 12 rupees
