Triangle XYZ is translated by the rule (x + 1, y − 1) and then dilated by a scale factor of 4 centered at the origin. Which statement describes the properties of triangles XYZ and X''Y''Z'' after the transformations?
A. Y and ∠Y'' are congruent after the translation, but not after the dilation.
B. ∠Y and ∠Y'' are congruent after the dilation, but not after the translation.
C. segment YZ and segment Y double prime Z double prime are proportional after the translation, but not after the dilation.
D. segment YZ and segment Y double prime Z double prime are proportional after the dilation and congruent after the translation.
Answers
The statement that described the triangle properties is that the segment YZ and segment Y"Z" should be proportional when the dilation is done and it should be congruent when the translation should be done.
Given that,
There is the rule i.e. (x +1, y - 1) and it should be dilated by a scale factor of 4 centered at the origin.Based on the above information,
The figure should be proportional as the angle and the points should be the same. And, when the translation is done the image should be congruent to the pre-imageTherefore we can conclude that option d is correct.

[tex]\implies x^2+y^2-4x -6y+9=0[/tex]
Step-by-step explanation:
Circle is touching y-axis at point (0, 3) and is centered at (2, 3)
-> h = 2, k = 3 & r = 2 units (If a circle touches y -axis then x coordinate of the center will be it's radius)
Equation of circle in standard form is given as:
[tex](x-h)^2 +(y-k)^2 =r^2[/tex]
Plugging the values of h, k and r in the above equation, we find:
[tex](x-2)^2 +(y-3)^2 =2^2[/tex]
[tex]\implies x^2-4x +4+y^2-6y+9=4[/tex]
[tex]\implies x^2+y^2-4x -6y+4+9=4[/tex]
[tex]\implies x^2+y^2-4x -6y+9=0[/tex]
This is the required equation of the circle.
A metal with a specific heat of 0.780 J/g oC requires 940 J of heat to raise the temperature (the change in temperature) by 15 oC. What is the mass of the metal?
SOMEONE HELP PLEASE GIVING BRIANLEST THANK YOU
Answers
Step-by-step explanation:
Q = msdt
or, 940 = m* 0.780* 15
or, 940 = 11.7m
or, 940/11.7 = m
m = 80.341
Therefore the mass of the metal is 80.341g.

well, the cheap answer is, linear expressions have one variable and some coefficient in front of it, like 3x or 2y + 3, or (1/4)x - 15 or such, however, a LINEar expression when drawn, yields a LINE, not a curve or such, and that only happens if the variable's exponent is 1, not more than 1, if the variable's exponent is higher, then is a curve of kinds,
so such expressions like -13xy, which has the product of two variables, or 7y³ - 2 or 4x⁵ + 9, are curvy lines.

The value of 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3.
What is a confidence interval?In statistics, a confidence interval is a range to estimate for unknown terms.
The most common level is the 95% confidence interval.
It can be calculated by
CI = Mean ± margin of error.
α = 1 - 0.95 = 0.05
α/2 = 0.025
z(0.025) = 1.96
We need to find the [tex]\frac{\sigma}{\sqrt{n} }[/tex]
[tex]\frac{5}{\sqrt{60} }[/tex] = 0.645
So,
[tex]z \times \frac{\sigma}{\sqrt{n} }[/tex] = 1.96 × 0.645
CI =1.26
C.I= 28±1.2652
Upper limit = 28+1.2652
=29.2625
Lower limit =28-1.2652
=26.7348
Hence, The value of 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3.

Answers
The system of equations 6x+4y=14 and 9x+6y=c are linear equations
The value of c that makes the system have infinitely many solutions is 21
How to determine the value of c?The system of equations are given as:
6x+4y=14
9x+6y=c
Divide through the second equation by 3
3x + 2y = c/3
Multiply through by 2
6x + 4y = 2c/3
Subtract the first equation from the above equation
6x - 6x + 4y - 4y = 2c/3 - 14
Evaluate the differences
2c/3 - 14 = 0
Add 14 to both sides
2c/3 = 14
Multiply by 3/2
c = 21
Hence, the value of c that makes the system have infinitely many solutions is 21
