Help me with this question please! how can you use multiplication to solve system of equations with the linear combination method? Edge answer please, Thank you!
Answers
Answer:
Put both equations into standard form (Ax+By=C).
Multiply one or both of the equations by a number so that you will have opposite coefficients on the same variable.
Add the two equations together. Add the x's, the y's, and the numbers.
Solve for the variable.
Take your answer from the last step and plug it into of the equations (pick the one that looks easiest).
Your solution will be in the form of a coordinate point (x,y).

A pyramid has a volume of 1,944 inches cubed and a rectangular base with the dimensions 18 inches by 9 inches. What is the height of the pyramid? 4 in. 12 in. 24 in. 36 in.
Answers
Answer: 4 inches
Step-by-step explanation: 1,944 / 18/ 9 / 1/3 = 4
Based on the calculations, the height of this pyramid is equal to: D. 36 inches.
Given the following data:
Volume of pyramid = 1,944 cubic inches.Dimensions of rectangular base = 18 inches by 9 inches.How to calculate the height of this pyramid?Mathematically, the volume of a pyramid is calculated by using this formula:
Volume = 1/3 × b × h
Where:
b is the base area.h is the height.For the base area, we have:
Base area = length × breadth
Base area = 18 × 9
Base area = 162 square inches.
Substituting the given parameters into the formula, we have;
1,944 = 1/3 × 162 × h
1,944 = 54h
h = 1,944/54
Height, h = 36 inches.

can someone help me on this problem what does it mean by a “smaller zero”? what is the zero
Answers
Answer:
(c) -2/5
Step-by-step explanation:
A "zero" or "root" or "x-intercept" of a function is a value of the independent variable (x) that makes the function (f(x)) have a value of zero. It is found where the graph of the function crosses the x-axis.
A quadratic function will have two (2) zeros. If they are different, one will be smaller than the other (leftmost on the number line).
Difference of squaresYou may recognize that 25x² and 4 are both perfect squares, (5x)² and 2², respectively. That means the expression (25x² -4) is the difference of squares.
The difference of squares is a special polynomial form, useful for the way it factors:
a² -b² = (a -b)(a +b)
Here, that means the factored form of f(x) is ...
f(x) = (5x -2)(5x +2)
Zero product ruleThe "zero product rule" says a product can only be zero if one or more factors is zero. This is exceptionally useful for determining the zeros of a polynomial function from its factored form.
It tells us f(x) = 0 only when one of (5x-2) = 0, or (5x+2) = 0. These are simple equations to solve to find the corresponding values of x:
5x -2 = 0 ⇒ 5x = 2 ⇒ x = 2/5
5x +2 = 0 ⇒ 5x = -2 ⇒ x = -2/5
Zeros of f(x)The above tells us the zeros of f(x) are -2/5 and 2/5. These values of x make f(x) = 0. The smaller zero is the one that is more negative: -2/5.
smaller zero: -2/5

Additional comment
A polynomial may have complex zeros. Only the real zeros will be x-intercepts on a graph of the function. Complex zeros must be found another way, not by graphing.

The dog park is 13 mile wide and 12 mile long. Shayna walks her dog, Buster, around the perimeter of the dog park two times. Explain how you determined whether Shayna and Buster walk more or less than 3 miles.
Answers
Answer:
Step-by-step explanation:
PERIMETER = 1/3 + 1/3 + 1/2 + 1/2 = 2/3 + 1 = 1 2/3 miles for 1 LAP.
For 2 LAPS, 2 x 1 2/3 = (2 x 1) + 2(2/3) = 2 + 4/3 = 2 + 1 1/3 = 3 1/3 miles
Or, 2 x 1 2/3 = 6/3 x 5/3 = 30/9 = 3 3/9 = 3 1/3 miles
Or, 2/1 x 5/3 = 10/3 = 3 1/3 miles
ANSWER: MORE THAN 3 MILES
=============================================================
Explanation:
We're given a 1/3 by 1/2 rectangle. The perimeter is:
P = 2(L+W)
P = 2(1/3+1/2)
P = 2(2/6+3/6)
P = 2(5/6)
P = 10/6
P = 5/3
The rectangle has a perimeter of 5/3 miles, which is equivalent to the mixed number of 1 & 2/3.
--------------
If Shayna and her dog walked the perimeter once, then the answer would be "less than 3 miles".
However, they walked around the park twice. We'll need to double the result.
2*(5/3) = 10/3 = 3 & 1/3
Therefore, they walked more than 3 miles.

Dave gave Heather directions on how to find where he had buried a box in his backyard. He didn’t want to make it easy for her, so he gave her complicated directions. This is what he said:
When you walk out of the back door of the house, you will be facing east. From there, walk straight ahead 10 feet. Turn 45° to your left, and then walk 5 feet. Next, turn 25° to your right and walk 12 feet. Finally, turn 110° to your right and walk 20 feet.
Based on these directions, which way will Heather be facing when she reaches the place where Dave buried the box?
Answers
Answer: She will be walking south or 90 degrees
Step-by-step explanation:
She walks ten spaces forward from where she started meaning the east
She turns 45 degrees left which places her at northeast
The walking doesn't affect her direction
So look at it like -45+25+110
This equals 90 degrees or south.

The circumference is basically the perimeter of the circle. To find the circumference, you do diameter • pi. Pi is a number that we use for finding circles. It goes on and on. They are still finding numbers to this day. For most problems, you will use 3.14. In order to find the diameter in this case, you will do circumference divided by pi. Because remember, C = D • pi. From there you will get your diameter. Hope this helps!!
