Which equation is equivalent to x + 8 = 21? (x + 8) × 4 = 21 (x + 8) × 4 = 21 ÷ 4 (x + 8) × 4 = 21 × 2 (x + 8) × 4 = 21 × 4
Answer:
(x + 8) × 4 = 21 × 4
Explanation:
x + 8 = 21
21 - 8 = 13
(13 + 8) × 4 = 21 × 4
21 × 4 = 21 × 4
84 = 21 × 4
84 = 84

Answer:
A) 55 + x ≤ 100
B) 55 + x ≤ 70
Step-by-step explanation:
A Explanation - Inequalities use signs < , > , ≤ , and ≥. We also know you have 100 seconds to beat the level, so you have to solve it in 100 or less, which tells us the 55 + the time left (x) must be less than or equal to 100. Solved will be attached.
B Explaination -
Like A, you can use the same setup, but switching a value. You already have the 55, you need 70. Or less points to ≤, same as before, so you can keep it the same, except with the 70 instead of the 100. Solved attached.

B.
C.
D.
E.
64

4.
Answer:
[tex]k = 4[/tex]
Step-by-step explanation:
Given
[tex]4x^2 - 8x + k[/tex]
Required
Determine k if the expression is a perfect square
A quadratic is of the form;
[tex]ax^2 + bx + c[/tex]
Where (by comparison):
[tex]a = 4[/tex] [tex]b = 8[/tex] [tex]c = k[/tex]
If the above is a perfect square, then
[tex]k = \frac{b^2}{4a}[/tex]
Substitute values for a, b and c
[tex]k = \frac{8^2}{4*4}[/tex]
[tex]k = \frac{64}{16}[/tex]
[tex]k = 4[/tex]
Hence, k = 4

Identify the solution to the system of equations graphed below.
segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
Answer:
YZ is located at Y (0, 1) and Z (-2, 1) and is one-third the size of Y'Z'.
Step-by-step explanation:
Since Y'Z' was dilated from the origin at a scale factor of 3, you can divide its X and Y coordinates by 3 to find the coordinates of YZ.
The statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.
What is dilation?The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.
The question is incomplete.
The complete question is:
Segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
segment YZ is located at Y (0, 9) and Z (−18, 9) and is three times the size of segment Y prime Z prime.segment YZ is located at Y (0, 3) and Z (−6, 3) and is the same size as segment Y prime Z prime.segment YZ is located at Y (0, 1.5) and Z (−3, 1.5) and is one-half the size of segment Y prime Z prime.segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime.As we know, in the dilation image of the two-dimensional figure can be larger or smaller depending on the dilation factor.
We have:
segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3).
After dilation:
Y (0, 1) and Z (−2, 1)
Thus, the statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.

What is matrix?In mathematics, a matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.
For example, is a matrix with two rows and three columns.
here, we have,
two matrices,
A = 2×3
and, B= 3×2,
as the no. of column of A = the no. of row of B
the can be a product matrix of order 2×2.

Step-by-step explanation:
5 < k -2 < 11 ?
-4 > y + 2 > -10 ?
5 -m < 4 or 7m > 35 ?
3 < 2p -3 < 12 ?
Answer:
[tex]7 < k < 13[/tex]
[tex]-6>y>-12[/tex]
[tex]m > 5[/tex]
[tex]3 < p < \frac{15}{2}[/tex]
Step-by-step explanation:
Given
[tex]5 < k -2 < 11[/tex]
[tex]-4 > y + 2 > -10[/tex]
[tex]5 -m < 4\ or\ 7m > 35[/tex]
[tex]3 < 2p -3 < 12[/tex]
Required
Solve
Solving (1):
[tex]5 < k -2 < 11[/tex]
The above can be represented as:
[tex]5<k -2[/tex] and [tex]k -2<11[/tex]
Solving [tex]5<k -2[/tex]
[tex]5 + 2 <k[/tex]
[tex]7<k[/tex]
Solving [tex]k -2<11[/tex]
[tex]k < 2 + 11[/tex]
[tex]k < 13[/tex]
So, we have:
[tex]7<k[/tex] and [tex]k < 13[/tex]
This can be combined as:
[tex]7 < k < 13[/tex]
Solving (2):
[tex]-4 > y + 2 > -10[/tex]
Split as:
[tex]-4 > y + 2[/tex] and [tex]y + 2 > -10[/tex]
Solving [tex]-4 > y + 2[/tex]
[tex]-4 - 2 > y[/tex]
[tex]-6 > y[/tex]
Solving [tex]y + 2 > -10[/tex]
[tex]y > -10 - 2[/tex]
[tex]y > -12[/tex]
So, we have:
[tex]-6 > y[/tex] and [tex]y > -12[/tex]
This gives
[tex]-6>y>-12[/tex]
Solving (3):
[tex]5 -m < 4\ or\ 7m > 35[/tex]
Solve for m in both cases:
[tex]5 - m < 4[/tex]
[tex]-m<4 - 5[/tex]
[tex]-m<- 1[/tex]
[tex]m > 1[/tex]
[tex]7m > 35[/tex]
Divide both sides by 5
[tex]m > 5[/tex]
So, we have:
[tex]m > 1[/tex] or [tex]m > 5[/tex]
The solution is [tex]m > 5[/tex] because [tex]5> 1[/tex]
Solving (4):
[tex]3 < 2p -3 < 12[/tex]
The above can be represented as:
[tex]3 < 2p - 3[/tex] and [tex]2p - 3<12[/tex]
Solving [tex]3 < 2p - 3[/tex]
Add 3 to both sides
[tex]3 + 3 < 2p - 3 + 3[/tex]
[tex]6 < 2p[/tex]
Divide both sids by 2
[tex]3 < p[/tex]
[tex]2p - 3<12[/tex]
Add 3 to both sides
[tex]2p - 3 + 3 < 12 + 3[/tex]
[tex]2p < 12 + 3[/tex]
[tex]2p < 15[/tex]
Solve for p
[tex]p < \frac{15}{2}[/tex]
So, we have:
[tex]3 < p[/tex] and [tex]p < \frac{15}{2}[/tex]
Combined as:
[tex]3 < p < \frac{15}{2}[/tex]

Part A: Given the drawing, what is the area of the wall?
The area of the wall is
square feet.
Part B: If one quart of paint will cover 22 square feet, how many whole quarts will Mr. Chen need to buy?
He will need to buy
whole quarts.
Area of the figure
= (area of rectangle) + (area of triangle)
= (8 × 10) + (½ × 4 × 8)
= 80 + 16
= 96
Area = 96ft²
Quarts of paint needed

Answer:
Step-by-step explanation:
2x - 5 = 15
Bringing like terms on one side
2x = 15 + 5
2x = 20
Option B is the correct answer
Answer:
b) 2x = 20
c) 2(x - 5) = 15
D) 2x - 20 = 0
Explanation
2x - 5 = 15
2x = 15 + 5
2x = 20
x= 20/2
x= 10
a) 2x = 10
x= 10/2
x= 5 (which is not correct)
b) 2x = 20
x= 20/2
x = 10 (which is correct )
c) 2(x- 5) = 15
2x - 10 = 15.
2x = 15 +10
2x = 20
x = 20/2
x= 10 ( which is correct)
d) 2x - 20 = 0
2x = 20
x= 20/2
x= 10 ( which is correct)
