how to solve 2x^2 - 4x = 3
Answer:
1 ± i(1/2)√2
Step-by-step explanation:
Write this quadratic in standard form: subtract 3 from both sides. This results in 2x^2 - 4x - 3 = 0. Let's apply the quadratic formula. The coefficients of the x terms are 2, -4 and -3, so the discriminant is (-4)^2 - 4(2)(-3), or 16 - 24 = -8.
Following the format of the quadratic formula, we get
-(-4) ±i2√8 4 ±i2√2
x = ----------------- = --------------- = 1 ± i(1/2)√2

Samantha and her children went into a grocery store and she bought $7 worth of bananas and peaches. Each banana costs $0.40 and each peach costs $0.50. She bought a total of 15 bananas and peaches altogether. Determine the number of bananas and the number of peaches that Samantha bought.
Answer:
Ten Peaches and five bananas.
Step-by-step explanation
To solve the problem increase the cost by adding more peaches and less by adding more bananas
7 peaches = 3.50
8 bananas = 3.20 + 3.50 = 6.70
We need 30 more cents so add three more peaches
10 peaches = 5
5 x 0.4 = 2
2 + 5 = 7
If the radius of a circle is 14 in, what is the diameter?
Answer:
28
Step-by-step explanation: radius is half the diameter
Step-by-step explanation:
In a circle
Radius (r) = 14 in
Diameter (d)
= 2 * r
= 2 * 14
= 28 in

Based on the observed frequencies, which percent represents a reasonable probability of rolling a number less than 3?
14%
o
33%
o
40%
O
49%
Answer:
40%
Step-by-step explanation:
In order to calculate this probability we need to calculate the frequency of all the numbers rolled that were less than three. Since this would be numbers 1 and 2 and 1 was rolled 6 times while 2 was rolled 8 times, therefore, we add these numbers together.
6 + 8 = 14
Since we are tolled that the total number of rolls were 35, we now divide the number of rolls that were less than 3 (14 rolls) by the total number of rolls made (35 rolls). This would give us the probability of rolling a number less than 3
14 / 35 = 0.4 ... multiply by 100 to get percentage
0.4 * 100 = 40%

Answer:
[tex] x = \dfrac{3+\sqrt{29}}{2},\dfrac{3-\sqrt{29}}{2}[/tex]
Step-by-step explanation:
This kinda Questions can be easily done using the Quadratic formula or Shreedhacharya's Formula . Which is used to find the roots of a quadratic equation in Standard form of ax² + bx +c = 0 .
Wrt . Standard form ,
[tex]\implies x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\implies x = \dfrac{-3\pm \sqrt{3^2-4(1)(5)}}{2(1)}\\\\\implies x = \dfrac{-3\pm \sqrt{9+20}}{2} \\\\\implies \boxed{\boxed{ x = \dfrac{3+\sqrt{29}}{2},\dfrac{3-\sqrt{29}}{2}}}[/tex]

After spending some time looking for his pump, Marlon pumps up an uninflated balloon, pumping air into it at a constant rate. He ties the balloon with a string to prevent the air from escaping.
Which graph could represent this scenario?
Answer:
Graph D
Step-by-step explanation:
Initially, Marlon was looking for his pump. Thus, no air was pumped into the balloon until he got the pump. On getting the pump, he inflated the balloon with air at a constant rate, after which he tied it with a string to prevent the air from escaping.
The analysis is that, at the time he decided to inflate the balloon till he got a pump, the volume of air in the balloon is zero with respect to time. Pumping air at a steady rate into the balloon increases the volume of air flowing into it gradually and steadily.
When the volume got to a definite amount, he stopped pumping air and tied with a string. Thus, the volume of air in the balloon remains constant.
pleas e help !?!?!!j
Answer:
see explanation
Step-by-step explanation:
step 2 : 4x + 4 - 2x = - 6x + 6 + 14
Simplify both sides by collecting like terms ← what was done
step 3 : 2x + 4 = - 6x + 20
------------------------------------------
step 4 : 8x + 4 = 20
Subtract 4 from both sides ← what was done
8x = 16

Which measurements could not represent the side lengths of a right triangle?
A 6 cm, 8 cm, 10 cm
B В
12 cm, 35 cm, 37 cm
C 4 cm, 6 cm, 10 cm
10 cm, 24 cm, 26 cm
Answer: C
Step-by-step explanation: a^2 + b^2 = c^2
A. 6^2 + 8^2 = 10^2
B. 12^2 + 35^2 = 37^2
C. 4^2 + 6^2 does not equal 10^2.....(16 + 36 = 52 10^2 = 100)
D. 10^2 + 24^2 = 26^2
The measures of the triangles 4 cm, 6 cm, and 10 cm do not represent a right angle triangle because it does not follow the Pythagoras theorem option (C) is correct.
What is a right-angle triangle?It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
For the triangle sides:
6 cm, 8 cm, and 10 cm
From the Pythagoras theorem:
[tex]10^2=8^2+6^2[/tex]
100 = 100
These sides satisfy the Pythagoras formula.
For the triangle sides:
12 cm, 35 cm, and 37 cm
From the Pythagoras theorem:
[tex]37^2=35^2+12^2[/tex]
1369 = 1369
These sides satisfy the Pythagoras formula.
For the triangle sides:
4 cm, 6 cm, and 10 cm
From the Pythagoras theorem:
[tex]10^2=6^2+4^2[/tex]
100 ≠ 52
These sides do not satisfy the Pythagoras formula.
For the triangle sides:
10 cm, 24 cm, and 26 cm
From the Pythagoras theorem:
[tex]26^2=24^2+10^2[/tex]
676 = 676
These sides satisfy the Pythagoras formula.
Thus, the measures of the triangles 4 cm, 6 cm, and 10 cm do not represent a right angle triangle because it does not follow the Pythagoras theorem option (C) is correct.

Answer:
The values of x and y are 23.83 and 31.1.
Step-by-step explanation:
Given that,
Perpendicular = 20 units
Angle, [tex]\theta=40^{\circ}[/tex]
We need to find the values of x and y.
Using trigonometry,
[tex]\tan(40)=\dfrac{20}{x}\\\\x=\dfrac{20}{\tan(40)}\\\\x=23.83[/tex]
To find y use Pythagoras theorem,
[tex]y^2=23.83^2+20^2\\\\y=31.1[/tex]
So, the values of x and y are 23.83 and 31.1.

An angle measures 32° less than the measure of its complementary angle. What is the
measure of each angle?
Answer:
First angle = x
Second angle = x - 32
We know that, complementary angles form => 90°
So,
[tex]x + x - 32= 90 \\ 2x = 90 + 32 \\ 2x = 122 \\ x = \frac{122}{2} \\ x = 61[/tex]
First angle,
=> x = 61°
Second angle
[tex]x - 32 \\ = 61 - 32 \\ = 29[/tex]
Second angle,
=> 29°

Ordena los términos del 1 al 5, de tal manera que
cada término se construya del término (s) anterio
Explica por qué cada figura está en el lugar que
eliges. Los términos son: cuadrilátero, cuadrado
rombo, rectángulo y paralelogramo
Answer:
El orden es;
1) Cuadrilátero, 2) Rombo, 3) Paralelogramo, 4) Rectángulo, 5) Cuadrado
Step-by-step explanation:
Los términos dados son;
Cuadrilátero; Una forma con cuatro lados
Rombo; Un cuadrilátero con cuatro lados iguales
Cuadrado; Un cuadrilátero con cuatro lados iguales y cuatro ángulos iguales y dos lados paralelos opuestos
Rectángulo; Un cuadrilátero con cuatro ángulos rectos y dos lados paralelos opuestos
Paralelogramo; Un cuadrilátero con un par de lados paralelos opuestos
Observamos que todos los términos son cuadriláteros, por lo tanto, el cuadrilátero es el primer término
Por lo tanto, tenemos,
La primera forma es el cuadrilátero,
El cuadrilátero se transforma en un rombo (un cuadrilátero con lados iguales)
El ángulo del rombo se ajusta para dar un paralelogramo
El ángulo de paralelogramo dado cuatro ángulos iguales de 90 ° para dar un rectángulo
El rectángulo se ajusta para dar un cuadrado con todos los lados iguales

calculate the value of x when y = 24.
Answer:
x = 24
Step-by-step explanation:
Complete question
Y and x have a proportional relationship, and y = 24 when x = 16 What is the value of x when y = 36?
If y is proportional to x, then;
y = kx
24 = 16k
k = 24/16
k = 1.5
Recall that y = kx
36 = 1.5x
x = 36/1.5
x = 24
Hence the required value of x is 24

Anna and Bill share a 16-ounce box of cereal. By the end of the week, Anna has eaten
5
8
of the box, and Bill has eaten
1
4
of the box of cereal. How many ounces are left in the box?
Answer:
2 ounces
Step-by-step explanation:
1 = 5/8 - 1/4 = 1/8
16 x 1/8 = 2 oz
Answer:
2 ounces left
Step-by-step explanation:
if anna ate 5/8 of the box, and Bill has eaten 1/4 of the box, then in total they’ve eaten 7/8 if the box (1/4 turns into 2/8 + 5/8)
1/8 of the box is left and 1/8 of 16 is 2. so 2 ounces would be left
