Solve each system of equations algebraically x-y=6 y=-1
Answer:
x-(-1)=6
-x=6
-x/-1 6/-1
x=-6
Answer:
Therefore, the solution of the system of equations will be:
[tex]x=5,\:y=-1[/tex]
Step-by-step explanation:
Given the system of equations
[tex]x-y=6;\:y=-1[/tex]
solving
[tex]\begin{bmatrix}x-y=6\\ y=-1\end{bmatrix}[/tex]

A bowl contains an apple, a plum, a pear, and a banana. How many different pairs of fruit can be selected from the bowl
Based on the information given about the combination, the number of different parts of fruits that can be selected from the bowl will be 6.
Solving the combination.Since the bowl contains an apple, a plum, a pear, and a banana, the different pairs of fruit that can be selected from the bowl will be 4C2.
We can solve this further which will be:
= 4C2
= 4! /2! (4 - 2)!
= 4! / 2!2!
= (4 × 3 × 2)/ 2 × 2
= 24/4
= 6
Therefore, 6 different pairs of fruit can be selected.

Jon is hanging a picture. He wants to center it horizontally on the wall. The picture is 32 1/2 inches long, and the wall is 120 3/4 inches long. How far from each edge of the wall should he place the picture? Please answer quickly.
Answer:
44.125 inches
Step-by-step explanation:
Given that:
Length of picture = 32 1/2 inches
Length of wall = 120 3/4 inches
Hence, to center picture horizontally ;
Distance from the edge of the wall in which the picture should be placed :
(Length of wall - length of picture) / 2
(120 3/4 - 32 1/2) / 2
(483/4 - 65/2) / 2
Take the L. C. M of 4 and 2 = 4
((483 - 130) / 4) ÷ 2
(353 / 4) ÷ 2
(353 / 4) * (1 / 2)
= 353 / 8
= 44 1/8
= 44 1/8
= 44.125 inches
The space that will be left in each side of the picture from the edge of the wall if Jon is to hang the picture at the center of the wall horizontally is: 44.125 inches.
The wall that Jon wants to hang the picture has been sketched in the diagram attached below (see attachment).
Given the following:
Length of the wall = 120 3/4 inches = 120.75 inchesLength of the picture = 32 1/2 inches = 32.5 inchesThe space in each edge of the wall = xTotal length of space to be left = x + x = 2xTherefore, the following equation can be derived as follows:
[tex]2x + 32.5 = 120.75[/tex]
Solve for x[tex]2x = 120.75 - 32.5 \\\\2x = 88.25\\\\x = \frac{88.25}{2} \\\\\mathbf{x = 44.125 $ inches}[/tex]
Therefore, the space that will be left in each side of the picture from the edge of the wall if Jon is to hang the picture at the center of the wall horizontally is: 44.125 inches.

3. In the expression 362 + 6, what will be the place value of the first digit of the quotient?
A. It will be the tens place because 6 is less than 3.
B. It will be the tens place because 6 is greater than 3.
O
C. It will be the hundreds place because 6 is less than 3.
d
D. It will be the hundreds place because 6 is greater than 3.
Answer:
B. It will be the tens place because 6 is greater than 3.
Step-by-step explanation:
Since the question said "quotient," then I believe we have 362 ÷ 6 and not "362 + 6."
If we work on the quotient we have
[tex]60\frac{1}{3}[/tex]
Obviously, the first digit in the quotient is 6 and it takes the place of tens.
Looking at the options, option B fits the most because 6 is actually greater than 3.
Therefore, the answer is option B, It will be the tens place because 6 is greater than 3.

what is the range of the relation graphed below?
Answer:
D. -2 ≤ y ≤ 2
Step-by-step explanation:
Range of a Relation
It's the set of values the relation takes when x moves into the relation's domain.
It can be graphically determined by placing imaginary horizontal lines from minus infinite to plus infinite. Where the line meets the relation's graph, that value of y belongs to the range.
If we place imaginary horizontal lines from -∞ up to y=-2, we won't meet the relation's graph. Exactly at y = -2, the line and the graph have one point in common.
Moving up the line will meet the graph until exactly y=2, from where there won't be any additional interceptions.
Thus, the range of the relation is [-2,2] or, written in inequality form:
D. -2 ≤ y ≤ 2

Please I need help and I’m stumped here.
Answer:
Step-by-step explanation:
1) For complex numbers addition, add the real parts and imaginary party separately.
(2 +5i) - (-6 + 3i) = 2 + 5i + 6 - 3i
= 2+ 6 + 5i - 3i
= 8 + 2i
2)Use FOIL method
(-4 +2i)(3 - 7i) = -4*3 + (-4)*(-7i) + 2i* 3 + (2i)*(-7i)
= -12 + 28i + 6i -14i² {i² = -1}
= -12 + 28i + 6i - 14*(-1)
= -12 + 28i + 6i + 14 {Combine like terms}
= -12 + 14 + 28i + 6i
= - 2 + 34i
3)Hint:
[tex]a^{mn} = (a^m)^{n}\\\\a^{m}*a^{n}= a^{m+n}[/tex]
[tex]\sqrt[4]{144x^{12}y^{7}} =\sqrt[4]{2*2*2*2*3*3*x^{3*4}*y^{4+3}} \\\\=\sqrt[4]{2^{4}*9*(x^{3})^{4}*y^{4}*y^{3}}\\\\=2*x^{3}*y\sqrt[4]{9y^{3}}\\\\ =2x^{3}y\sqrt[4]{9y^{3}}[/tex]
4)
[tex]\sqrt[3]{\frac{320a^{10}}{27b^{6}}}= \sqrt[3]{\frac{8*8*5a^{3+3+3+1}}{3*3*3b^{3+3}}}\\\\=\sqrt[3]{\frac{2^{3}*2^{3}*5a^{3}*a^{3}*a^{3}*a}{3^{3}b^{3}*b^{3}}}\\\\=\frac{2*2*a*a*a}{3b*b}\sqrt[3]{\frac{5a}{1}}\\\\=\frac{4a^{2}}{3b^{2}}\sqrt[3]{5a}[/tex]
5) 4x² + 28x + 49 = 4x² + 14x +14x + 7*7

6) 2x² + 3x - 20 = 2x² +8x - 5x - 5 *4

Answer Choices
A. Open Circle is for greater than or less than symbols, closed circles are for greater than or equal to or less than or equal to.
B. Both choices are correct
C. Open Circle means that the solution cannot be the answer, closed circle means that the answer can be part of the solution.
Answer:
i think its c
Step-by-step explanation:
Open circle means that the solution cannot be the answer, closed circle means that the answer can be part of the solution. Therefore, option B is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The difference between an open and closed circle when graphing inequalities are
A closed circle indicates "greater than or equal to" or "less than or equal to," while and open circle indicates "greater than" or "less than".
Therefore, option B is the correct answer.

The sum of 7 and w is greater than 21.
?
Answer:
[tex]7+w \ge 21[/tex]
remove the line under the arrow
Answer:
w>14
Step-by-step explanation:
"sum" means adding together. So, the sum of 7 and w would be 7+w. The equation states that this sum is greater than 21, so:
7+w>21
if you want a simplified version, subtract 7 from both sides to get w>14
