Solve each system by elimination: -6x-y=-17 -2x-3y=-3
Answer:
(3, -1)
Step-by-step explanation:
Multiply the 2nd equation (-2x-3y=-3) times -3 to eliminate x
Subtract/add the other terms -y + 9y and -17 + 9
Then divide 8y = 8
y= -1
Substitute y in the other equation
x = 3
(3, -1)
Answer:
Point Form: ( 3 , − 1 )
Equation Form: x = 3 , y = − 1
Step-by-step explanation:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

HELPPP ILL DO ANYTHING HELPPPP
Answer:
-2
Step-by-step explanation:
hi! to find f(-3) on this graph, go to the x-value -3 and find the y-value there. when we look at -3 on the x-axis, we go down and see that there is a point at (-3,-2). therefore, f(-3)=-2.

What is the function of the line?
Answer:
It is a linear function.
Step-by-step explanation:
The graph shows a straight line. Therefore the function must be linear. Unless you were asking about the equation of the line? Let me know.
To find the equation of this line, you would take the two points it passes through, (-3, 0) and (0, -2), and plug it into the slope formula, (y2-y1)/(x2-x1).
This would get you (-2 - 0)/ (0 - (-3)), which is -2/3.
Then, you can use slope intercept form to write the equation, since you have the y intercept already, (0, -2). Slope intercept is y=mx+b.
The line of the equation would then be y = -2/3x -2

what is the fraction equivalent of 3 4/5
Answer:
19/5 (improper fraction), 3.8 (decimal form) those are all I can think of
solve for p
19/20=3p/18
Answer:
p=5.7
Step-by-step explanation:
Cross multiply.
Answer:
p = 5.7
Step-by-step explanation:
Given
[tex]\frac{19}{20}[/tex] = [tex]\frac{3p}{18}[/tex] ( cross- multiply )
60p = 19 × 18 = 342 ( divide both sides by 60 )
p = [tex]\frac{342}{60}[/tex] = [tex]\frac{57}{10}[/tex] = 5.7

What are the solution(s) of x2-4-0?
X=-4 or X-4
X=-2 or X= 2
X=2
X=4
Answer:
X = - 2 or X = 2
Step-by-step explanation:
*completing the square*
X^2 - 4 = 0
X^2 = 4
X = +-√4
x = +-2
x= -2, 2
*factoring*
X^2 - 4 = 0
(x-2)(x+2) = 0
|. |
x = 2, x = -2
________________________________
(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4

Answer:
96 cm^2
Step-by-step explanation:
The triangle can be split into 2 6-8-10 triangles, each with area 24. The bottom parallelogram area is base times height, or 8 * 6, so 48. 24 + 24 + 48 is 96.

x2y4(x2 - 16) - 9y4(x4 - 16)
simplify
Step-by-step explanation:
given the expression
[tex]x^22y^4(x^2 - 16) - 9y^4(x^4 - 16)[/tex]
we proceed by opening the brackets
[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16) \\\\x^4y^4-16x^2y^4-9x^4y^4+144y^4\\\\[/tex]
collet like terms we have
[tex]x^4y^4-16x^2y^4-9x^4y^4+144y^4 \\\\x^4y^4-9x^4y^4-16x^2y^4+144y^4 \\\\8x^4y^4-16x^2y^4+144y^4[/tex]
factoring we have
[tex]8x^4y^4-16x^2y^4+144y^4\\\\8y^4(x^4-2x^2)+144y^4[/tex]
it says round to the nearest hundredth
Answer:
I think it's 3.83
Answer:
Rounded to the nearest hundredth, the answer is 3.83cm^3
Step-by-step explanation:
The equation for the volume of a pyramid is
Lwh/3
The length is 1.8, the width is 2.2, and the height it 2.9. These multiplied together is 11.484. Divide that by three, and you get your answer of 3.828, which when rounded to the nearest hundredth place is 3.83.

Please help??? Thank you !!
Answer:
54w-9
Step-by-step explanation:
the box to the right is -1 because you are multiplying 6w-1 by 9 (the box next to the blank one on the bottom). the other blank box below the 6w is going to be 54w since you multiply 6w and 9 to get that. therefore, 9(6w-1) is 54w-9.
