Answer:
The solutions to the quadratic equation using the quadratic formula will be:
[tex]x=\frac{1}{2},\:x=\frac{1}{4}[/tex]
Step-by-step explanation:
Given the equation
[tex]8x^2-6x+1=0[/tex]
solving with the quadratic formula
[tex]\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}[/tex]
[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]\mathrm{For\:}\quad a=8,\:b=-6,\:c=1[/tex]
[tex]x_{1,\:2}=\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:8\cdot \:1}}{2\cdot \:8}[/tex]
as
[tex]\sqrt{\left(-6\right)^2-4\cdot \:8\cdot \:1}=2[/tex]
so
[tex]x_{1,\:2}=\frac{-\left(-6\right)\pm \:2}{2\cdot \:8}[/tex]
Separating the solution
[tex]x_1=\frac{-\left(-6\right)+2}{2\cdot \:8},\:x_2=\frac{-\left(-6\right)-2}{2\cdot \:8}[/tex]
solving
[tex]x_1=\frac{-\left(-6\right)+2}{2\cdot \:\:8}[/tex]
[tex]=\frac{6+2}{2\cdot \:8}[/tex]
[tex]=\frac{8}{16}[/tex]
[tex]=\frac{1}{2}[/tex]
and
[tex]x_2=\frac{-\left(-6\right)-2}{2\cdot \:8}[/tex]
[tex]=\frac{6-2}{2\cdot \:\:\:8}[/tex]
[tex]=\frac{4}{16}[/tex]
[tex]=\frac{1}{4}[/tex]
Therefore, the solutions to the quadratic equation using the quadratic formula will be:
[tex]x=\frac{1}{2},\:x=\frac{1}{4}[/tex]

In the diagram, lines AB , CD, and EF intersect at G
Answer:
D. 70°
Step-by-step explanation:
Given:
m<DGB = 35°
m<CGF = 75°
Required:
m<AGE
SOLUTION:
m<EGD = m<CGF (vertical angles are congruent)
m<EGD = 75°
m<AGE + m<EGD + m<DGB = 180° (angles on a straight line)
m<AGE + 75° + 35° = 180° (substitution)
m<AGE + 110° = 180°
Subtract 110 from each side of the equation
m<AGE = 180° - 110°
m<AGE = 70°

One angle of an isosceles triangle measures 94 degrees. Which other angles could be in that isosceles triangle？Choose all that apply.
Answer:
43
Step-by-step explanation:
Other two angles are equal and let it be 'x'
x + x + 94 = 180
2x + 94 = 180
2x = 180 - 94
2x = 86
x = 86/2
x = 43

he steps below describe the construction of a line AG that is parallel to segment PQ and passes through a point A outside of PQ: Step 1 shows a segment PQ with an external point A. A line drawn from A intersects PQ at a point B. Step 2 shows an arc drawn from B that intersects BQ in D and BA in E. Step 3 shows an arc drawn from Point A that intersects the segment BA extended in a point F. Which statement describes the next step?
Answer: Point G is obtained by using the same compass width and drawing an arc from point F, intersecting the arc drawn from A
Step-by-step explanation:
I took the test and got the right answer
The steps for constructing a parallel line require steps for constructing
angles of equal measures.
The statement that describes the next step is; The width of the compass is adjusted to DE and an arc is drawn from point F.Reasons:
The steps to construct the AG parallel to PQ, passing through the point A
outside of PQ are as follows;
Step 1; A line is drawn from point A to intersect PQ at point B.
Step 2; From point B on PQ, an arc is drawn intersecting segment BQ of PQ at D and segment BA at point E.
Step 3; To construct the angle equal to angle ∠DBE at point A, an arc is drawn from Point A with radius BD, that intersects the segment BA extended in point F
Therefore;
To construct an angle equal to the angle ∠DBE to point A, we have;
The width of the compass is adjusted to DE, and an arc is drawn from point F to intersect the arc drawn from point A with radius BD at point G.The points A and G can then be joined with a straight line and extended to form the line AG.
The correct option is therefore;
The width of the compass is adjusted to DE and an arc is drawn from point FLearn more about constructing a parallel line here:

Answer:
7.65
Step-by-step explanation:
The total cost for 8 is 20.40, so you want to find what the cost for one panel is by dividing the total cost by the amount, which would be 20.40/8=2.55 then you want to know how much 3 of them cost, to find that you just multiply the cost of one of them by three, which would be 7.65
The function ƒ(x) is a translation of the exponential function g(x) = 6x. What's ƒ(x) if the translation is down 3 units and right 7 units?
Answer:
f(x) = 6ˣ⁻⁷-3
Step-by-step explanation:
The basic transformations of an exponential function from the parent function can be given by the equation:
f(x) = b^x [parent exponential function]
f(x) = ab^((x/c)-h) + k [transformation of parent exponential function]
Where b is the parent growth or decay, a is the vertical stretch or compression, c is the horizontal stretch or compression, h is the horizontal translation, and k is the vertical translation.
Given a translation down 3 units, and another translation right 7 units, we are only using h, and k.
Given that our original function is g(x) = 6ˣ. We know our parental growth or b is 6. So just substitute our quantities and solve:
f(x) = g(x-7) - 3 → (1)6^((x/1)-7) - 3 → 6^(x-7) - 3 → 6ˣ⁻⁷-3.
Answer:
f(x) = 6ˣ⁻⁷-3
