Ap ex: What is the solution to this system of equation?
y = x - 4 y = -0.5x + 8
a. (4,2)
b. (8,4)
c. (4,8)
d. (2,4)
Answers
Answer:
x = 8, y = 4
Step-by-step explanation:
y = x - 4
y = -0.5x + 8
y = y
x - 4 = -0.5x + 8
x + 0.5x = 8 + 4
1.5x = 12
x = 12/1.5
x = 8
To get "y" substitute the 8 for the "x" value in any of the two equations (they will both give the same answer.)
y = (8) - 4
y = 4
OR
y = -0.5(8) + 8
y = -4 + 8
y = 4

Three times a day, Dylan mixes 2 ounces of protein powder into a shake. How many days can he make all three shakes from his 5-pound container of protein powder? Remember, there are 16 ounces in a pound. Enter your answer in the box.
Answers
Answer:
13 days
Step-by-step explanation:
To calculate this we first need to find the total number of ounces in the container. We do this by multiplying the total number of pounds in the container by 16oz
5 * 16oz = 80oz
Since Dylan is making three 2oz shakes per day that would mean he is using a total of 6oz (2oz*3) per day. Therefore, in order to find out how many days the container will last we simply divide the total amount of protein powder in the container by the amount he uses every day.
80oz / 6oz = 13.33 days
The container will last 13.33 days but since we cannot count a percentage of a day, then we need to round down to the day in which he will no longer be able to make the three shakes which are 13 days.

Suppose a lab need to need to make 400 liters of 39% acid solution, but the only solutions available to the lab are 20% acid and 50% acid. What system of equation can be used to find the number of liters of each solution the should be mixed to make the 39% solution? Let c represent the number of liters of 20% acid solution and let d represent the number of liters of 50% acid solution.
Answers
Answer:
c + d = 400
0.2c + 0.5d = 156
Step-by-step explanation:
Let
c = number of liters of 20% acid solution
d = number of liters of 50% acid solution.
c + d = 400 (1)
0.2c + 0.5d = 400(0.39)
0.2c + 0.5d = 156 (2)
From (1)
c = 400 - d
Substitute c = 400 - d into (2)
0.2c + 0.5d = 156 (2)
0.2(400 - d) + 0.5d = 156
80 - 0.2d + 0.5d = 156
- 0.2d + 0.5d = 156 - 80
0.3d = 76
d = 76/0.3
d = 253.33 liters
Substitute d = 253.33 into (1)
c + d = 400
c + 253.33 = 400
c = 400 - 253.33
c = 146.67 liters
Two triangles have the same base lengths. One Triangle has the height that is 4 times the height of the other triangle. Are the heights and the areas of the two triangles proportional?
Answers
YES
Area of Triangle 1Base=b
Height= h
Area 1=A1=1/2*b*h
Area of Triangle 2Base=b
Height= 4h
Area of triangle 2=A2=1/2*b*4h
Comparing A1 and A2A2/A1= (1/2*b*4h)/(1/2*b*h)
= (1/2*b*4h)/(1/2*b*h)
=4/1
Ratio of heights =h2/h1= 4/1
Ratio of areas =A2/A1= 4/1
They are proportional.

Which one of these transformations would produce an image that is not congruent to its pre-image? (4 points)
A translation of (x − 1, y − 3)
A rotation of 90 degrees about the origin
A rotation followed by a translation
A dilation followed by a reflection
Answers
Answer:
A dialation followed by a reflection
Step-by-step explanation:
When you dialate a shape it changes the size which makes the shape similar but not congrouent.
The option “a dilation followed by a reflection” will produce an image that is not congruent to its pre-image option, fourth is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
As we know, the translation will shift the object.
If rotate the image with 90 degree about origin will change the orientation of the image but shape will remains same.
A dilation followed by reflection will change the image because the transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller.
Thus, the option "a dilation followed by a reflection" will produce an image that is not congruent to its pre-image option fourth is correct.

(i) Find its length (ii) Find its perimeter
11
Answers
Answer:
i) the length is 10cm
ii) the perimeter is 36 cm
Step-by-step explanation:
i) We know that Area of a rectangle can be found by using the following formula...
A = l x w
(where A is area of the triangle, l is the length of the triangle, and w is the width of the rectangle).
From this we know that
l = A/w
[tex]l = 80cm^{2} / 8cm = 10cm[/tex]
ii) Now that we know both the length and the width we know we can find the perimeter by using the following formula...
P = 2(l + w)
[tex]P = 2(10cm+ 8cm )\\P = 20cm + 16cm\\P = 36cm[/tex]
