Josephine wanted to create a blueprint of her new rectangular garden she is planning on making in her backyard. She began to cre

ate the blueprint of the garden plotting the following points A(-5, 25), B(5, 25) and C(5,-25).
Part A: Find the area of the rectangular garden assuming the units are represented in feet.

Part B: Jenna wants to build a square, grass patch in the garden that initially is placed in Quadrant II. She wants to use reflections to move the patch from Quadrant II to Quadrant I. Discuss how she can do this.

Answer:

A: 500 square feet

Step-by-step explanation:

A: First you have to draw a grid.

You plot the points A,B, and C.

The fourth point would be -5,25 because it matches with the points.

You make a rectangle out of those points

Points AB is 2 feet. Since the interval I used was 5 I would multiply 2 by 5 to get 10.

Then I would find Points BC which is 10 feet. Again multiply it by 5 to get 50.

50 x 10 is 500.

B: Jenna has to reflect over the y-axis. This is because the y-axis is between Quadrants II and I. When reflecting over the y-axis the y-coordinate stays the same but the x-coordinate switches to it's opposite. Basically the x-coordinate is negative in Quadrant II, but in when reflecting over the y-axis the x-coordinate would change to a positive in Quadrant I. So if the point in Quadrant II looks like this: (-X,Y) then when reflecting over the y-axis to Quadrant I would look like this: (X,Y).

What does 6•7-27•9+64=
Natali [406]

Hi!

6*7-27*9+64

42-27*9+64

42-243+64

Answer---->=-137

Explanation: <u><em>This question is super super easy to me. This question is about how to use their order of operations the math problems. First you had  to used PEMDAS stands for P-Parenthesis first, E-Exponents second, M-Multiply third, D-Divide fourth, A-Add fifth, and S-Subtract sixth.  Then multiply and divide from left to right  with 6*7=42. Then 27*9=243,42-243+64, and add or subtract from left to right with 42-243+64=-137 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>

What is the domain of the function graphed below?
I am Lyosha [343]

Answer:

x < 7

Step-by-step explanation:

the domain is the number range or interval of x the function is defined for to generate a y-value.

the graph shows that the y-values continue with x-values to the right up to but not including 7 (the empty dot says "excluding"). and with x- values to the left to negative infinity.

x=-1 is not a problem, because while for the left part of the function it is not included, but for the right part it is.

so, it is fully defined for all x < 7.

△ABC∼△DEF , △ABC has a height of 14 centimeters, and △DEF has a height of 6 centimeters. What is the ratio of the area of △ABC t
Kamila [148]
Since triangle ABC is similar to triangle DEF then the ratio of the corresponding sides is constant.
The ratio of the corresponding lengths is referred to as the linear scale factor.
Considering the heights of the two triangles;
L.S.F = 14/6
          = 7/3
The ratio in area (A.S.F) is given by (L.S.F)²
Therefore, A.S.F = (7/3)² = 49/9
Thus te ratio of the area of triangle ABC to DEF is 49:9

2(3x+8)=6x+16<br> how many solutions does this equation have
Kisachek [45]

Answer:

infinite

Step-by-step explanation:

infinite

but solving for it we can get

3x + 8 = 3x + 8 (divided both sides by 2)

3x = 3x (subtracted 8)

x = x

1 = 1

therefore, for all values of x, the equation will be true so there are

infinite solutions
