Answer:
True
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

Answer:
422.5
Step-by-step explanation:
Given,
Diameter = 23.2
Radius = 23.2 ÷ 2 = 11.6
So, Area is
[tex] = \pi {r}^{2} [/tex]
[tex] = 3.14 \times 11.6 \times 11.6[/tex]
= 422.5184
As rounding to nearest tenth we check the hundreth digit i. e.
422.5184
Since, 1 is smaller than 5 so,
422. 5 (Ans) (Rounded to nearest tenth)

Explain how to find the value of y in the equation 6(y+4)=12
Answer:
y=-2 (Please can i have brainliest????)
Step-by-step explanation:
There are different ways to do this but my way, you would distribute 6 to both y and 4, ending up with 6y+24=12. You then subtract 24 from both sides giving you, 6y=-12. Then divide both sides by 6, giving you y=-2
Answer: y=-2
Step-by-step explanation:
First, you would distribute the 6 to both the y and the 4 which would give you 6y+24=12
Then you would subtract 24 from 12 to get -12 ( it would look like 6y= -12 after)
Finally, you would take -12/6 to get -2 so y = -2

simplify the expression 6h + (-8.1d) - 13 + 5d - 2.4h
Answer:
3.6h - 3.1d + 13
Step-by-step explanation:
Combine like terms. Like terms have same variables.
Like terms : (i) 6h and (-2.4h) (ii) -8.1d and 5d
6h + (-8.1d) - 13 + 5d - 2.4h = 6h - 2.4h + (-8.1d) + 5d - 13
= (6 - 2.4)h + (-8.1 + 5)d - 13
= 3.6h - 3.1d + 13

Which expression is equivalent to the given expression? 6ab/(a^0b^2)^4
Answer:
B
Step-by-step explanation:
[tex]x^{0} = 1\\\\\frac{x^{m}}{x^{n}}= \frac{1}{x^(n-m)}}, n >m\\\\\\\frac{6ab}{(a^{0}b^{2})^{4}}=\frac{6ab}{(1*b^{2})^{4}}\\\\=\frac{6ab}{b^{2*4}}\\\\=\frac{6ab}{b^{8}}\\\\=\frac{6a}{b^{8-1}}\\\\=\frac{6a}{b^{7}}[/tex]
The equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7
How to determine the equivalent expression?The expression is given as:
6ab/(a^0b^2)^4
Evaluate the exponent of 0
6ab/(b^2)^4
Apply the law of indices, and open the bracket
6ab/b^8
Apply the law of indices
6a/b^(8-1)
Evaluate the difference
6a/b^7
Hence, the equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7

They say.. use Pythagorean theorem formula.... what is it? :) you have to remember it. I'll put it below in case you don't remember
Step-by-step explanation:
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] +[tex]B^{2}[/tex]
and I know, you're thinking..... what's the deal with all the letters... how do I add those up? :D ..... you are right... you can't add letters... the letters are just the variables... or places holders for numbers... you can put many different numbers into each of them but... the relationship.... which is made by the equal sign.. must hold true for any numbers you put in for the variables.... sooo.. like this.. for your particular answer
[tex]19^{2}[/tex] = [tex]10^{2}[/tex] + [tex]y^{2}[/tex]
( notice I've put in a " y " , where there is a B in the formula above but that's just a letter... again.. which is just a variable... the place holder for a number... soooo..... )
361 = 100 + [tex]y^{2}[/tex] ( subtract 100 from each side of the " = " )
261 = [tex]y^{2}[/tex] ( to undo the square on the wye... square root both sides)[tex]\sqrt{261}[/tex] = y
my calculator tells me that [tex]\sqrt{261}[/tex] = 16.15549442
they say round to the nearest 10th... soooo..

The length of wall is 30 feet. How long is 25% of the length? Round to the nearest tenth if necessary.
Answer:
25% of the length is 7.5 (seven and five tenths) feet
Step-by-step explanation:
25% of 30
7.25 feet is 25% of length.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
The length of wall is 30 feet.
So, 25% of length
= 30 x 25/100
= 30 x 1/4
= 30/4
= 7. 25 feet
Hence, 7.25 feet is 25% of length.

The product of two consecutive numbers is 72. Use a quadratic equation to find the two sets of numbers.
Given:
The product of two consecutive numbers is 72.
To find:
The two numbers by using the quadratic equation.
Solution:
Let the two consecutive numbers are x and (x+1).
The product of two consecutive numbers is 72.
[tex]x(x+1)=72[/tex]
[tex]x^2+x-72=0[/tex]
Splitting the middle term, we get
[tex]x^2+9x-8x-72=0[/tex]
[tex]x(x+9)-8(x+9)=0[/tex]
[tex](x+9)(x-8)=0[/tex]
Using zero product property, we get
[tex]x+9=0[/tex] and [tex]x-8=0[/tex]
[tex]x=-9[/tex] and [tex]x=8[/tex]
If [tex]x=-9[/tex], then
[tex]x+1=-9+1[/tex]
[tex]x+1=-8[/tex]
If [tex]x=8[/tex], then
[tex]x+1=8+1[/tex]
[tex]x+1=9[/tex]
Therefore, the two consecutive numbers are either 8,9 or -9,-8.

Fishing for Saturday =2 5/6 hours
We need to find for how long Diana went fishing on Friday and Saturday combined. It means we need to add the time for Friday and Saturday. So,
[tex]T=3\dfrac{7}{12}+2\dfrac{5}{6}\\\\=\dfrac{3(12)+7}{12}+\dfrac{2(6)+5}{6}\\\\=\dfrac{43}{12}+\dfrac{17}{6}\\\\=6.41\ \text{hours}[/tex]

Answer:
424 cm²
Step-by-step explanation:
The figure is composed of a square and a trapezium on top
A of square = 18² = 324 cm²
A of trapezium = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 8, b₁ = 18 and b₂ = 7 , then
A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²
Area of hexagonal park = 324 + 100 = 424 cm²
