-4x+y=1
2y-2=8x
How many solutions does this have?
a. no solution
b. one solution
c. infinitely many solutions
Answer:
c. infinotely msny solutions
Answer:
Step-by-step explanation:
y = 4x + 1
2y - 2 = 8x
2(4x + 1) - 2 = 8x
2x + 2 - 2 = 8x
2x + 0 = 8x
6x = 0
x = 0
y = 0 + 1
y = 1
(0, 1)
answer is b. one solution
Find the areas of the composite figure.
Answer:
Step-by-step explanation:
A tv is sold for ra 10350 with 15% profit. Find the cp of tv
CP=SP*100÷100+P
so,
CP=10350*100÷100+15
CP=9000
Answer:
solution
Step-by-step explanation:
Let.the cp of TV be RS X
now,CP=SP-profit
or, CP=SP-profit% of Cp (as profit amount =profit % of Cp)
or, x=Rs 10350-15÷100× X
or, x= Rs 10350 _ 3X ÷20
or, x+3x ÷20 =Rs 10350
or, 23x ÷20 = Rs 10350
or, x = 10350×20 divided by 23
Therefore X =Rs 9000

Find the missing length of the triangle.
Answer:
11 [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex] (Pythagorean Theorem)
[tex]a^{2}[/tex] + [tex]4^{2}[/tex] = [tex](12\frac{1}{3})^{2}[/tex] (square numbers)
[tex]a^{2}[/tex] + 16 = 152 [tex]\frac{1}{9}[/tex] (subtract 16, both sides
[tex]a^{2}[/tex] = 136 [tex]\frac{1}{9}[/tex] (square root both sides)
a = 11 [tex]\frac{2}{3}[/tex] or 11.66 repeating

yes, it is a function.
the reason : every value of x (2, 4, -2, 0) has exactly one assigned value of y : 2 to 3, 4 to 5, -2 to -1, 0 to 1.
that is the definition of a function.

A circular rug has a diameter of 12 feet. What is the area, in square feet , of the rug rounded to the nearest hundredth? Use 3.14 for it
Answer:
113.04 ft^2
Step-by-step explanation:
area of circle formula = [tex]\pi r^{2}[/tex]
in this case, we are taking π as 3.14, so it is 3.14 x [tex]r^{2}[/tex]
Radius = half of diameter
radius = 12 / 2 = 6
[tex]6^{2}[/tex] = 36 (because 6 x 6 = 36)
3.14 x 36 = 113.04
Therefore, our answer is 113.04 ft squared (because it is area)

What is an asymptote?An asymptote is a straight line that approaches a curve indefinitely but does not intersect at any point. In other words, when a curve approaches infinity, it approaches an asymptote line.
The function that is given to us is:
[tex]f(x)=\dfrac{x+1}{6x^2-7x-3}[/tex]
As in the function, there is a fraction therefore, the denominator should not be zero in order for the function to be defined. Therefore, there are asymptotes at
[tex]6x^2-7x-3 = 0\\[/tex]
Substituting the value in the formula of the quadratic equation we will get,
[tex]D=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\D = \dfrac{-(-7)\pm\sqrt{(-7)^2-4(6)(-3)}}{2(6)}\\\\D =\dfrac{-(-7)\pm\sqrt{11}}{12} = \dfrac{3}{2}, \dfrac{-1}{3}[/tex]

Answer: 18x + 12
Step-by-step explanation:
Step #1: Determine the length of each side.
The polygon is regular, so all the sides are equal. Thus, all sides measure 3x+2.
Step #2: Determine the number of sides in the polygon.
This polygon is identified as a hexagon meaning it consists of 6 sides.
Step #3: Set up an expression and distribute.
(Number of sides) x (Length of each side)
(6)(3x+2)
6 times 3x equals positive 18x6 times 2 equals positive 12So, the answer is 18x + 12.
Answer:
B. 3x + 2
Step-by-step explanation:
The polygon has 6 equal sides.
1 side has a side length of 3x + 2
Therefore, all sides of the polygon measure 3x + 2

Step-by-step explanation:
The attached figure is drawn to scale, and a grid is provided that makes it easier to see the dimensions of the various parts.
This figure can be easily decomposed into an overall rectangle with cutouts of a trapezoid at the top and a rectangle at the bottom right.
__
The overall rectangle has dimensions 8 units wide and 10 units high.
The trapezoid at the top has bases of 8 units and 7 units, and a height of 2 units.
The rectangle at the bottom right has dimensions of 4 units wide and 3 units high.
The area formulas for a rectangle and trapezoid are ...
A = LW . . . . area of a rectangle with length L, width W
A = 1/2(b1 +b2)h . . . . area of a trapezoid with bases b1, b2, and height h
__
Then the area of the figure is ...
figure area = overall rectangle - trapezoid - lower right rectangle
= (8 in)(10 in) - 1/2(7 in + 8 in)(2 in) -(4 in)(3 in)
= 80 in² -15 in² -12 in² = 53 in²
The area of the object is 53 square inches.
