Answers
Answer:
(2, 5), (-5, 6) and (-1, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point A(x,y) is translated a units right and b units up, the new location is at A'(x + a, y + b).
From the image attached, the location of the vertices of the triangle is at (0,2), (-7, 3) and (-3, -2). If the triangle is under the translation (x, y) ⇒ (x + 2, y + 3), the new location of the vertices would be at (2, 5), (-5, 6) and (-1, 1)

Grant bought strawberries and bananas from the grocery store to make smoothies. The total amount he spent can be represented by the expression 1.8s + 0.65b, where s is the number of pounds of strawberries and b is the number of pounds bananas. If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas, how much did he spend? Amount spent can be represented by the exper
Answers
Answer:
$5.77
Step-by-step explanation:
Given expression:
1.8s + 0.65b
where,
s = the number of pounds of strawberries
b = the number of pounds bananas
If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas
s = 2.7 pounds
b = 1.4 pounds
how much did he spend?
1.8s + 0.65b
= 1.8(2.7) + 0.65(1.4)
= 4.86 + 0.91
= $5.77
He spent $5.77 on both items

Leon is using an area model to multiply 38×14. First, he makes a rectangle that is 38 units long and 14 units tall. Then, he breaks it into smaller parts using place value to make it easier to multiply. Use the drop-down menus to show the area of each part.
Answers
Answer:
300, 120, 80 and 32 respectively.
Step-by-step explanation:
To break it down for easy multiplication, write
38 as 30 + 8
14 as 10 + 4
Now let's multiply
(30 + 8)(10 + 4) = 300 + 120 + 80 + 32
So the areas of each part would be
300, 120, 80 and 32 respectively.

Maurice and his father are building a dog house. They are using long pieces of wood and cutting them into smaller pieces. They have a piece of wood that is 3.6 feet long and are cutting it into pieces that are each 0.75 feet. How many smaller pieces will they be able to make?
Answers
Answer:
4.8 smaller pieces
Step-by-step explanation:
Total length of wood = 3.6 feet
Length of each piece = 0.75 feet
How many smaller pieces will they be able to make?
Number of smaller pieces of wood = Total length of wood / Length of each piece
= 3.6 feet / 0.75 feet
= 4.8 smaller pieces
Number of smaller pieces of wood = 4.8

A high school track team's long jump record is 24 ft 9 1/4 in. This year, Arthur's best long jump is 24 ft 3 1/2 If long jumps are measured to the nearest quarter inch, how much farther must jump to break the record?
Answers
Answer:
5 3/4 inches
Step-by-step explanation:
Given that :
Long jump record held = 24 ft 9 1/4 in
Arthur's best long jump record = 24 ft 3 1/2 in
How much further must ARTHUR jump to brake the record :
Long jump record - Arthur's best jump
[24 ft 9 1/4 in] - [24 ft 3 1/2 in]
24 ft - 24 ft = 0
9 1/4 in - 3 1/2 in
37 / 4 in - 7 /2 in
L. C. M of 4 and 2 = 4
(37 - 14) / 4 inches

constant width around the border for labeling purposes (game console type, etc). This width will
take up 32% of your game cover's total space. What is the width of the border? Make sure to
state any values that don't make sense.
Answers
20cm×15 cm =300
32
/100 = 0.32
9514 1404 393
Answer:
1.5 cm
Step-by-step explanation:
All areas are in cm^2. For a width w, the border will have an area equal to the product of its centerline length and its width:
border area = 2((20-w) +(15-w))·w = w(70 -4w)
This area is 32% of the total cover area, so is ...
0.32(20)(15) = 96
Equating these expressions for the area gives ...
96 = 70w -4w^2
w^2 -17.5w = -24 . . . . . divide by -4
w^2 -17.5w +8.75^2 = -24 +8.75^2 . . . . . complete the square
(w -8.75)^2 = 52.5625 . . . . simplify
w -8.75 = ±√52.5625 = ±7.25
A border width only makes sense if it is between 0 and 7.5 cm, so the appropriate value for w is ...
w = 8.75 ± 7.25 . . . . . . . . . add 8.75
w = 8.75 -7.25 = 1.50 . . . . . the solution w=16 makes no sense
The border width is 1.5 cm.
Identify The domain of the rational function, g(x)= 1/x+3
A (-∞, ∞)
B (-∞, 3)U(3, ∞)
C (-∞, -3]U[-3, ∞)
D (-∞, -3)U(-3, ∞)
Answers
Answer:
The domain is (-∞ , -3) ∪ (-3, ∞) ⇒ D
Step-by-step explanation:
The domain of the rational fraction is the values of x which make the fraction defined. That means the domain does not contain the values of x which make the denominator equal to 0.
∵ g(x) = [tex]\frac{1}{x+3}[/tex]
∴ The denominator = x + 3
→ Equate the denominator by 0
∵ x + 3 = 0
→ Subtract 3 from both sides
∴ x + 3 - 3 = 0 - 3
∴ x = -3
→ That means the domain can not have -3 because it makes the denominator
equal to 0
∴ The domain is all values of real numbers except x = -3
∴ The domain = {x : x ∈ R, x ≠ -3}
∴ The domain = (-∞ , -3) ∪ (-3, ∞)
