Answer:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex], [tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
Step-by-step explanation:
Use the quadratic formula to solve for all real solutions.
Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Plug in and solve:
[tex]x=\frac{-17\pm\sqrt{17^2-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-12(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-192}}{2(3)}\\\\x=\frac{-17\pm\sqrt{97}}{6}\\[/tex]
Since that's the farthest we can simplify to, your answers would be the positive and negative versions of the expression:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex]
and
[tex]x=\frac{-17-\sqrt{97}}{6}[/tex]

Give one verbal expression (VE) and its equivalent algebraic expression (AE).
Example: VE: my age increased by half the age of Ellie AE: x + 1/2y
Answer:
A few examples:
VE: Three more than two times the temperature.
AE: 2x+3
VE: The money I have decreased by two thirds of the money you have.
AE: x - (2/3)y
VE: The number of friends I have increased by four times the amount of friends you have.
AE: x + 4y

Answer:
[tex]\frac{9}{5}[/tex] or [tex]1\frac{4}{5}[/tex]
Step-by-step explanation:
First add 1/5 from both sides to get 2/3x > 6/5. This can then be simplified to x > 18/10. 18/10 is the same as 9/5. And 9/5 is also 1 4/5.
Hope it helps!
Answer:
[tex]x>\frac{9}{5}[/tex]
Step-by-step explanation:
To reduce any confusion later on in the problem the first step should getting the fractions to have an equal denominator, this can be done by finding the LCF, or Least Common Factor.
In this case the least common factor is [tex]15[/tex], [tex]3[/tex] × [tex]5 = 15[/tex], and [tex]5[/tex] × [tex]3 = 15[/tex]; whatever you do to the denominator has to be done to the numerator
[tex]\frac{2}{3}[/tex] × [tex]\frac{5}{5} = \frac{10}{15}[/tex] [tex]\frac{1}{5}[/tex] × [tex]\frac{3}{3} =\frac{3}{15}[/tex]
Now that the denominators are equal, lets input the values into the original equation:
[tex]\frac{10}{15} x-\frac{3}{15} >1[/tex]
add [tex]\frac{3}{15}[/tex] to both sides, to isolate the variable
[tex]\frac{10}{15}x > 1\frac{3}{15}[/tex] [tex]or \frac{18}{15}[/tex]
divide
both sides by [tex]\frac{10}{15}[/tex], when you divide fractions you multiply by the reciprocal of the divisor, then you multiply the numerators by the numerators and the denominators by the denominators. [tex]18[/tex] × [tex]15[/tex][tex]=270[/tex] , [tex]15[/tex] × [tex]10=150[/tex]
[tex]x>\frac{18}{15}[/tex] × [tex]\frac{15}{10}[/tex] ⇒ [tex]x>\frac{270}{150}[/tex]
[tex]270[/tex] and [tex]150[/tex] have a GCF, or Greatest Common Factor of [tex]30[/tex] which simplifies the answer to:
[tex]x>\frac{9}{5}[/tex]

Paige is a graphic designer who makes logos for companies. She makes a design for a logo, which is in the shape of a square. The design of this logo is drawn on the coordinate plane as square ABCD. She then dilates this logo by a scale factor of 2, forming square A'B'C'D'. She realizes that she needs a much bigger design and so further dilates this transformed square by a scale factor of 3 to form A"B"C"D". What are the coordinates of vertex A' and vertex C"?

Answer: triangles are similar.
Step-by-step explanation:
Givn : OK = 3, OJ = 30, KN = 1, JM = 3#
Angle O is common in both the triangles.
Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.
That means
That means the three angles of triangle OKJ are equal to the corresponding three angles of triangle ONM.
Hence the to triangles are similar.

Find the mean of the data 18,36,24,36,30,36
Answer:
30
Step-by-step explanation:
To calculate the mean, add up all the numbers in the data and divide the sum by the number of numbers in the data.
(18+36+24+36+30+36)/6 = 30.
Answer:
30
Step-by-step explanation:
To find mean, add up all the numbers, then divide by how many numbers there are:
18 + 36 + 24 + 36 + 30 + 36/6
180/6 = 30

Consider the following set of 19 data values:
5 6 6 9 10 4 2 5 7 6 7 3 5 5 5 4 9 2 10
Round to 1 decimal for each answer if needed. If there is no mode type NONE in the answer box. If there is more than one mode, separate each value with a comma.
Mean =
Median =
Mode=
Answer:
mean = 5.4
median = 5
mode = is the number that appears the most answer = 5
Step-by-step explanation:
mean
5+6+6+9+10+4+2+5+7+6+7+3+5+5+5+4+9+2+10 = ......... / 19 = 5.4
median
2 2 3 4 4 5 5 5 5 5 6 6 6 7 7 9 9 10 10 then find the middle between these = 5
Turn this into a formula and step by step on how to solve it.
