Answer:
X = 4, x = -7
Step-by-step explanation:
You can set each equation in the parenthesis Equal to 0.
x - 4 = 0 and x + 7 = 0
start with x - 4 =0
add 4 to both sides
x = 4.
then do x +7 =0. subtract 7 from both sides.
x = -7
so x =4, and x = -7

The function f(x) = -x² + 8x-7 is translated five units down. Write the new equation in vertex form and state the vertex.
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).

The quotient of 5 times a number and 7 is equal to 10. What is the number?
Write as an equation then answer
Solve the equation 6x+3y=3
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

Answer:
x=3
Step-by-step explanation:
for 17.
we have that x=8 as one solution
then we have
x-8=0
so we know that
[tex]f(x)=(x-8)(something)[/tex]
[tex]\frac{f(x)}{x-8}=something[/tex]
so we divide and get that
[tex]something = x^{2} -6x+9x[/tex]
and we can factor it as
[tex](x-3)(x-3)[/tex]
so the other solutions are
x-3 =0
x = 3
this is a normal division
Answer (#17):
(x-3) (x-3) or (x-3)²
Step-by-step explanation:
See attachment to find simplified equation. I can't explain synthetic division very well. Please find other sources to learn synthetic division or traditional algebraic long division.
Anyway, the image should be read first while this text explains the second part. Now you have the second equation, it can be factored down.

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]

Perpendicular lines create obtuse angles where they intersect.
True
False
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

Solve for x: 7 + 4x = 13+ X. Select one: a. x = 1 1/5 b.x=2 x 2 C. X= 4 d. x = 6 2/3
Answer:
7+4x=13+x
4x-x=13-7
3x=6
3 3
x =2
Step-by-step explanation:
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
which is 3x=6 so u divide both sides by the coefficient of x which is three which will give u 2

Let u = {1,2,3,4,5,6,7}, L={1,3,5,73 M = { 1, 2,3}
N={2,3,4,5,6}

Answer:
{1,3,4,5,6,7}
Step-by-step explanation:
Here , U represents the universal set
L’ = {2,4,6}
L’ is what we have in the universal set but not present in set L
(m n L’)
This is the set that contains the elements that are present in both set ONLY
So this is;
{2}
(M n L’)’ = {1,3,4,5,6,7}
N’ = {1,7}
So the union of both would be;

Point C (3, 4) is the midpoint of AB If the coordinates of A are (7, 6), what are the coordinates of B?
O (5.5)
0 (11,8)
O (2, 1)
0 (-1,2)
Answer:
c??
Step-by-step explanation:
The coordinates of B are (1,2).
What is Midpoint?A midpoint is a point lying between two points and is in the middle of the line joining the two points.
Given that, Point C (3, 4) is the midpoint of AB If the coordinates of A are (7, 6),
Formula of midpoint coordinates = (x1+y1)/2, (x2+y2)/2
Therefore, (7+x)/2, (6+y)/2 = (3,4)
Comparing both side, we get,
(7+x)/2 = 3
x = 1
And, (6+y)/2 = 4
y = 2
Hence, The coordinates of B are (1,2).
