Which transformation, when performed on the triangle ABC, will result in the transformed figure A'B'C being similar but NOT congruent to the original triangle?
Answer:
b. a dilation by a scale factor of 2
Step-by-step explanation:
Which transformation, when performed on the triangle ABC, will result in the transformed figure
A'B'C' being similar but NOT congruent to the original triangle?
a. a reflection over the x-axis
b. a dilation by a scale factor of 2
C.a translation two units to the right
d. a rotation 90° clockwise about the origin
Solution:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Rigid transformation are transformation that preserves the size and shape of a figure. Examples of rigid transformation are reflection, translation and rotation.
Dilation preserves the shape but not the size of a figure.
If translation, rotation or reflection is done on triangle ABC, the transformed figure would be congruent to the original triangle. But, if dilation is done, the transformed figure would be similar but NOT congruent to the original triangle.
is y+7=2x a direct variation
Answer:
No, y+7=2x does not represent direct variation
Step-by-step explanation:
No, y+7=2x does not represent direct variation, because of the constant (initial value) 7.
y = 2x represents direct variation; y = 2x - 7 does not.
Which expression is represented by the model?
the slope of the line that passes through the points (-2,-1) and (-2,7)
Answer:
The answer is zero.
Step-by-step explanation:
When you put the coordinates in the point-slope formula, it will be 7 - (-1) over -2 - (-2), which is 8/0. When the denominator is zero in the fraction, the answer is zero.

Smoothies weren't cutting it so we went to Red Robin to order a burger. Our bill was $5.79. Avon has a 5.25% tax and our
waitress earned a 15% tip. What was the total bill?
Answer:
$6.96
Step-by-step explanation:
5.25% of 5.79
5.79 × 5.25/100 = $0.303975 or $0.30
15% of 5.79
5.79 × 15/100 = $0.8685 or $0.87
total
$5.79 + $0.30 + $0.87 = $6.96
Read the problem.
Jordan and Roman travel the same route to work. Jordan leaves for work one morning and drives at a rate, r, of 56 mph. Roman leaves the house soon after, when Jordan has already traveled 2 mi. Roman drives at a rate of 60 mph. How long after Jordan leaves home will Roman catch up to her? How many miles into their commute will this occur?
Which system of equations models this problem?
d = 56t
d = 58t
d = 56t
d = 62t
d = 56t
d = 60t – 2
d = 56t
d = 60t + 2
Step-by-step explanation:
D= 56t
D= 60t -2
D= Distance T=time d = 56t (Jordan) d = 60t - 2 (Roman)
d = 56t d = 60t - 2
56t = 60t - 2 d = 56(1/2) d = 60(1/2) - 2
-60t -60t d = 28 d = 30 - 2 = 28
-4t = -2
t = 1 / 2

d) y^6/y^2
Step-by-step explanation:
y^6/y^2= y^4
Answer:
Last Option [tex] {y}^{6} \div {y}^{2} [/tex]Step-by-step explanation:
This is because,
As,
[tex] {a}^{x} \div {a}^{y} = {a}^{x - y} [/tex]
Here ,
[tex] {y}^{6} \div {y}^{2} [/tex]
[tex] = {y}^{6 - 2} [/tex]
[tex] = {y}^{4} [/tex]
And here the result does not simplify to,
[tex] {y}^{3} [/tex]
Hence, Last Option is the correct answer

Which equation represents the line that passes through the point (-3, 2) and has a slope of 2
Why is it the right answer?
Step-by-step explanation:
y = mx+b
y - 2 = 2(x - -3)
y-2 = 2x +6
y = 2x +8
Answer:
y=2x+4
Step-by-step explanation:
okay so basically we have a slope value (m=2) and a point (-3,2). we can put these into the point slope formula, which is
(y-y1)=m(x-x1)
(we need to leave a y and an x in order have the actual equation)
so we just plug in the values (y1=2 ; x1=-3 ; m=2)
(y-2)=2[x-(-3)]
y-2=2(x+3)
y=2x+6-2
y=2x+4

find the product of (5x+4)(5x-4)
Answer:
25x² - 16
Step-by-step explanation:
Given
(5x + 4)(5x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
5x(5x - 4) + 4(5x - 4) ← distribute parenthesis
= 25x² - 20x + 20x - 16 ← collect like terms
= 25x² - 16
