Solve the equation 6x+3y=3
Answers
Answer:
x=−1/2 y+ 1/2
Step-by-step explanation:
Let's solve for x.
6x+3y=3
Step 1: Add -3y to both sides.
6x+3y+−3y=3+−3y
6x=−3y+3
Step 2: Divide both sides by 6.
6x /6= −3y+3/6
x=−1/2 y+ 1/2
The slope is -1: (-4, -1)
Which option?
y = 1x-4
y = -1x-4
y = -1x-5
-1 = (-1)(-4)+b

Perpendicular lines create obtuse angles where they intersect.
True
False
Answers
Answer:
The answer is false
Step-by-step explanation:
Perpendicular lines create four 90 degree angles thus if you connect the edges you make a square that has four 90 degree corners. Lines that can crate obtuse angles are called intersecting angles. And parallel never touch so they don't make any angles

The function f(x) = -x² + 8x-7 is translated five units down. Write the new equation in vertex form and state the vertex.
Answers
Answer:
The resulting equation in the vertex form is [tex](y-4)=-(x-4)^2[/tex] having the vertex at the point (4,4).
Step-by-step explanation:
The given function is f(x) = -x² + 8x-7.
As the given function is translated 5 units down, so, subtract 5 units in the given function.
The resulting function, y = f(x) -5
[tex]\Rightarrow y= - x² + 8x - 7 - 5 \\\\\Rightarrow y = - x² + 8x - 12[/tex]
Now converting the obtained equation to vertex form,
[tex]y= - x² + 8x - 12 \\\\\Rightarrow y = -(x^2-8x+12) \\\\[/tex]
Adding and subtraction 4 as
[tex]y= -(x^2-8x+12+4-4) \\\\\Rightarrow y= -(x^2-8x+16-4) \\\\\Rightarrow y= -((x-4)^2-4) \\\\\Rightarrow (y-4)=-(x-4)^2[/tex]
The vertex of the above equation is (4,4).
Hence, on translating five units in the downwards direction, the resulting equation in the vertex form is [tex](y-4)=-(x-4)^2[/tex] having the vertex at the point (4,4).
On translating five units in the downwards direction, the resulting equation in the vertex form is (y-4)=-(x-4)² having the vertex at the point (4,4).
The given function is f(x)= -x²+8x-7.
A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other.
When the shape is moved down by k units, then replace y with y - k.
The function f(x) = -x² + 8x-7 is translated five units down.
That is, y=f(x)-5
y=-x² + 8x-7-5
y=-x² + 8x-12
Subtract 4 on both the sides of an equation, we get
(y-4)=-x² + 8x-12-4
(y-4)=-x² + 8x-16
(y-4)=-(x²-8x+16)
(y-4)=-(x-4)²
Hence, on translating five units in the downwards direction, the resulting equation in the vertex form is (y-4)=-(x-4)² having the vertex at the point (4,4).

Use Green's Theorem to evaluate C F · dr. (Check the orientation of the curve before applying the theorem.) F(x, y) = x + 10y3, 10x2 + y C consists of the arc of the curve y = sin(x) from (0, 0) to (π, 0) and the line segment from (π, 0) to (0, 0)

Answer:
[tex]\mathbf{- 20 \pi + \dfrac{40}{3}}[/tex]
Step-by-step explanation:
Given that:
[tex]\int\limits_c {F} \, dr[/tex]
where;
[tex]F(x,y) = \langle\sqrt{x} + 10y^3+10y^2 + \sqrt{y} \rangle[/tex] and C consist of the arc of the curve, This shows that C is a closed curve.
Thus, using Green's theorem for clockwise orientation.
[tex]\int \limits_CF. dr = \iint_D \Biggl \langle \dfrac{\partial Q}{\partial X} - \dfrac{\partial P }{\partial Y} \Biggl \rangle dA[/tex]
Then;
[tex]F(P,Q) = \langle\sqrt{x} + 10y^3+10y^2 + \sqrt{y} \rangle[/tex]
[tex]\int \limits _CF. dr = -\iint_D \Biggl \langle \dfrac{\partial}{\partial} ( 10x^2 + \sqrt{y} -\dfrac{\partial}{\partial y } ( \sqrt{x} + 10y^3) \Biggl \rangle dA[/tex]
[tex]\int \limits _CF. dr = -\iint_D \Biggl \langle 10(2x)-10(3y^2) \Biggl \rangle dA[/tex]
[tex]\int \limits _CF. dr = \iint_D \Big \langle -20x+30y^2 \Big \rangle dA[/tex]
y → 0 to sin (x) x → 0 to π
[tex]\int \limits _CF. dr = \int \limits ^{\pi}_{0} \int \limits ^{sin \ x }_{0} \Big \langle -20x+30y^2 \Big \rangle dydx[/tex]
[tex]\int \limits _CF. dr = \int \limits ^{\pi}_{0} \Biggl [ -20xy + \dfrac{30 \ y^3}{3} \Biggl ] ^{sin\ x}_{0} \ dx[/tex]
[tex]\int \limits _CF. dr = \int \limits ^{\pi}_{0} \Big [ -20x \ sin x + 10 \ sin^3x \Big ] \ dx[/tex]
replace [tex]sin^3 x = \dfrac{3}{4} \ sin x - \dfrac{1}{4} \ sin (3x)[/tex]
[tex]= \int \limits ^{\pi}_{0} -20 x sin x dx + \int \limits ^{\pi}_{0} 10(\dfrac{3}{4} sin x - \dfrac{1}{4} sin (3x) ) \ dx[/tex]
By applying integration by posits
[tex]\int (u)(v') \ dx = (u)(v) - \int (u') (v) \ dx \\ \\ u = -20x \ \ \ \ \ \ \ v'= sin \ x \\ \\ u' = -20 \ \ \ \ \ \ \ v = - cos \ x[/tex]
[tex]= (-20x) (-cos x) - \int (-20)(-cos x) \ dx + 10 \Big [\dfrac{3}{4} \ cos x + \dfrac{1}{12}\ cos (3x) \Big ][/tex]
[tex]= 20x \ cos x - 20 \ sin x- \dfrac{15}{2} \ cos \ x + \dfrac{5}{6} \ cos (3x) \Biggl |^{\pi}_{0}[/tex]
[tex]= ( -20 \pi -0 +\dfrac{15}{2}-\dfrac{5}{6}) - (0-0-\dfrac{15}{2}+\dfrac{5}{6})[/tex]

because when 7 crosses the equal to sign it becomes negative and when the x from the other side crosses the equal sign it also will become negative which will become 4x-x=13-7

5.2x-y=4.1 1.5x+y=6.7
how to solve this problem
Answers
Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2
Answer:
x = 1.61 (Estimated)
y = 4.28 (Estimated)
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
5.2x − y = 4.1
−y = −5.2x + 4.1
y = 5.2x − 4.1
Solve for x:
1.5x + y = 6.7
1.5x + 5.2x − 4.1 = 6.7
6.7x − 4.1 = 6.7
6.7x = 10.8
x = 1.61194
Solve for y:
y = 5.2x − 4.1
y = 5.2 × 1.61194 − 4.1
y = 4.28209
The perimeter of the rectangle below is 65 inches.
a. What is the value of x?
b. What are the dimensions of the rectangle?
Answers
perimeter = 65 inches
Side ‘a’ = 2x
Side ‘b’ = 3 1 by 4x + 1
Solution -
Perimeter = 65
= a + b = 65
= 2x + 3 1 by 4x + 1 = 65
( 3 1 by 4 = 4 x 3 + 1 = 12 + 1 by 4
= 13 by 4 )
= 2x + 13 by 4x + 1 = 65
= 2x + 13 by 4x = 65 - 1
= 2x + 13 by 4x = 64
= 15 by 4 x = 64
= x = 64 x 4 by 15
= x = 256 by 15
= x = 17.06

so we divide and get that
