1. Change each of the following equations to the form
y = mx + c. Then, state the values of m and c.
(a) -6x- y = 3
(b) 3x - 4y = 12
(c)-2x + 5y = 10
(d) x + 2y = 4
(e) 8x- 4y = 3
(1) 4x + 5y = -6
Answer:
(a) -6x- y = 3
[tex]6x + y = -3\\ y = -6x -3[/tex]
(b) 3x-4y =12
[tex]3x - 4y = 12\\-4y = -3x +12\\4y = 3x -12\\\\y = \frac{3}{4}x -3[/tex]
(c)-2x + 5y = 10
[tex]-2x + 5y = 10\\5y = 2x + 10\\y = \frac{2}{5}x + 2[/tex]
(d) x + 2y = 4
[tex]x+2y=4\\2y = -x + 4\\y = \frac{-1}{2} x +2[/tex]
(e) 8x- 4y = 3
[tex]8x - 4y =3\\-4y = -8x + 3\\4y = 8x -3\\y = 2x -\frac{3}{4}[/tex]
(f) 4x + 5y = -6
[tex]4x + 5y = -6\\5y = -4x - 6\\y = \frac{-4}{5} x -\frac{6}{5}[/tex]

Answer:
Your answer is 211.8
Step-by-step explanation:
We've made a right triangle so the equation is a²+b² = c²
141²+158² = c²
141²+158² = 44845
Then you square root it
√44845 = 211.8
can someone help please it’s algebra 2
Answer:
length :16cm
wide :20cm
We have
Area of inner frame :16*20=320cm²
For
Total area =464cm²
(20+2x)(16+2x)=464cm²
320+32x+40x+4x²=464cm²
4x²+72x+320-464=0
4x²+72x-144=0
4(x²+18x-36)=0
x²+2.9.x+9²=9²+36
(x+9)²=117
x+9=√117
x=10.81-9
x=1.82[approximately]
So
width of frame;20cm+1.82+1.82=23.64cm
length: 16+1.82+1.82=19.64cm
Here length is smaller than breadth.

Answer:
C. AB = 5.8 cm
Step-by-step explanation:
In trapezoid ABCD, EF is Midsegment.
[tex] \therefore EF =\frac{1}{2} (AB + CD) [/tex]
[tex] \therefore 9.2 =\frac{1}{2} (AB + 12.6) [/tex]
[tex] \therefore 9.2\times 2= AB + 12.6[/tex]
[tex] \therefore 18.4= AB + 12.6[/tex]
[tex] \therefore 18.4-12.6= AB [/tex]

Two plumbers received a job. At first, one of the plumbers worked alone for 1 hour, and then they worked together for the next 4 hours. After this 40% of the job was complete. How long would it take each plumber to do the whole job by himself if it is known that the first plumber would take 5 more hours to finish the job than the second plumber?
Answer:
Which subject is optional in the morning??
A plumber has been working at 4 customer sites. He has completed 1/4, 50%, 12.5%, 3/4 and of his work at the sites. Which list shows the work completed at the sites, in order from greatest to least? 1. 12.5%, 1/4, 50%, 3/4 2. 3/4, 50%, 1/4, 12.5% 3. 3/4, 12.5%, 1/4, 50% 4. 1/4, 50%, 3/4, 12.5%
Answer:
2. 3/4, 50%, 1/4, 12.5%
Step-by-step explanation:
Work completed at the 4 sites = 1/4, 50%, 12.5%, 3/4
1/4 = 0.25
50%
= 50/100
= 0.5
12.5%
= 12.5/100
= 0.125
3/4
= 0.75
in order from greatest to least?
3/4, 50%, 1/4, 12.5%
1. 12.5%, 1/4, 50%, 3/4
2. 3/4, 50%, 1/4, 12.5%
3. 3/4, 12.5%, 1/4, 50%

Which number line model represents the expression 6+(-2)?
Number line model represented in option C represents the expression 6 + (-2).
What is Number Line?Number line is a pictorial representation of numbers, both negative and non-negative numbers, written on a horizontal straight line within specific intervals.
Number line are used to determine basic mathematical operations like addition, subtraction, division and multiplication.
So here, we are adding the value -2 with 6.
First draw an upward arrow from 0 to 6 in order to represent that we are initiating the addition process with 6.
Then the number -2 added to 6 implies that the number 2 is actually deducting from 6.
So we draw a downward arrow to unit units from 6.
Then we get the number 4 corresponding to the point where the arrow ends.
Hence, option C is the model which represents the expression 6 + (-2).

Step-by-step explanation:

(cosA+sinA)
2
+(sinA−cosA)
2
=2
Answer:
Here we want to solve:
(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2
First, remember the two expansions:
(a + b)^2 = a^2 + 2*a*b + b^2
(a - b)^2 = a^2 - 2*a*b - b^2
Using these relations, we can expand:
(cos(A) + sin(A))^2 = cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2
( sin(A) - cos(A))^2 = sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2
Replacing that in our equation, we geT:
(cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2) + (sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2) = 2
We can simplify this to get:
2*cos(A)^2 + 2*sin(A)^2 + 2*cos(A)*sin(A) - 2*cos(A)*sin(A) = 2
2*cos(A)^2 + 2*sin(A)^2 = 2
We can take the 2 as a common factor to get:
2*cos(A)^2 + 2*sin(A)^2 = 2*( cos(A)^2 + sin(A)^2) = 2
Now we can divide both sides by 2:
2*( cos(A)^2 + sin(A)^2)/2 = 2/2
cos(A)^2 + sin(A)^2 = 1
And this is a trigonometric property that is true for any value of A.
So the equality:
(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2
is true for any real value of A.

Please help calculate the surface area
Answer:
SA = 189 cm^2
Step-by-step explanation:
What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!
Starting with triangles: area = 1/2 * l * h
So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2
Since we have two triangular sides, that totals to 24 cm^2.
Then the rectangular sides: area = l*h
so, 5*11 = 55 cm^2
We have three rectangular sides, totalling 165 cm^2
165+24 = 189 cm^2
Answer:
200 [tex]cm^{2}[/tex]
Step-by-step explanation:
SA = LA + 2B where LA is the lateral area and B is the area of the base(triangle)
LA = ph p = perimeter of base and h = distance between bases
LA = (5 + 5 + 6)11 = 176
B = bh/2 = 6(4)/2 = 12
SA = 176 + 2(12) = 176 + 24 = 200 [tex]cm^{2}[/tex]
