2x^4=9x^2 solve by factoring
Answers
Step-by-step explanation:
2x⁴ = 9x²
2x⁴ - 9x² = 0
x²(2x² - 9) = 0
Either x² = 0 or 2x² - 9 = 0.
When x² = 0, x = 0.
When 2x² - 9 = 0, x² = 9/2, x = ± 3/√2.
Hence the solutions are
x = 0, x = 3/√2 and x = -3/√2.

Answers
Answer:
20&22
Step-by-step explanation:
let the numbers be X and X+2.
By question, X×(X+2)=440
or, X^2+2X=440
or, X^2+2X-440=0
or, X^2+(22-20)X-440=0
or, X^2+22X-20X-440=0
or, X(X+22)-20(X+22)=0
or, (X+22)(X-20)=0
Either,X-20=0 Or, X+22=0
•°•X=20(true) •°• X=-22(false)
•°•X=20
•°•X+2=20+2=22

Answer: 15.199
Step-by-step explanation:
Using the Pythagorean theorem, we know that a²+b²=c²
In this case, we know that c is 16, and that b is 5.
We can rearrange the equation so that it becomes a²=c²-b²
a²=16²-5²
a²=256-25
a²=231
√a²=√231
a=15.199
Ivide 28 pieces of candy into 2 groups so the ratio is 2 to 5. How many pieces of candy will be in each group?
Answers
Answer: 8 and 20
Step-by-step explanation:
From the question, we are informed that 28 pieces of candy are put into 2 groups in the ratio is 2 to 5.
The number of pieces of candy that will be in each group will be:
1st group = 2/(2 + 5) × 28
= 2/7 × 28
= 2 × 4
= 8
2nd group = 5/(2 + 5) × 28
= 5/7 × 28
= 5 × 4
= 20

Answers
Answer:
y = -x and 2y = 3x - 10 is the system of equations.
Step-by-step explanation:
Let,
Larger number = x
Smaller number = y
According to given statement;
x + y = 0
y = -x
And
3x - 2y = 10
Or it can be written as;
2y = 3x - 10
Therefore,
y = -x and 2y = 3x - 10 is the system of equations.
The image of the point (-1, -1)(under a translation is (4, 4)( Find the coordinates of the image of the point (-6, 5) under the same translation.
Answers
to get from (-1,-1) to (4,4) you go right 5 and up 5. Or just adding 5 to both -1s. Doing the same to (-6,5) gives you (-1,10)
The coordinates are (-1, 10).
What is translation?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. They just have been shifted in one or more directions. Since it is just moving of the shape from one place to other, there is no change in the shape.
Translation is one of the transformations in math. When a shape has been transformed, the original shape is called the preimage and the vertices are usually labeled using uppercase letters (Example: ABCD). The translated shape is called the image and the vertices are labeled using uppercase letters with a “prime” next to each (Example: A′B′C′D′, and is pronounced “A-prime, B-prime, C-prime, D-prime”).
Given:
the point is (-8, 3) whose image point is (-5, 2)
The difference between the coordinates of the image and the coordinates of the original is the same for both points.
X - (-6, 5) = (4, 4) -(-1, -1)
X = (4, 4) -(-1, -1) +(-6, 5) = (4+1-6, 4+1+5)
X = (-1, 10)
Hence, the point is (-1, 10)

Katty went online and visited website for a bank to check the interest rates on savings accounts. For $750 deposit, she can earn 4.5% for 3 years at the bank. Calculate the interest earned. *
Answers
Answer:
After 3 years she will have earned $101.25 in interest and her total amount of money will be $851.25
Step-by-step explanation:
In order to find the amount of money earned you first have to multiply 4.5% in decimal form by 750. From this you get 33.75. This is the amount of interest earned in one year.
Then you have to multiply the interest of one year by 3, since she will be keeping the money in the account for a 3 year minimum. This equals 101.25. $101.25 the money she will have earned over interest after 3 years.
To get the total amount of money she will have earned in her account you have to add 101.25 to 750 which has a sum of $851.25.
Hope this helps :)

Molly's hair was 20 inches long. Three years later it was 53 inches long. What was the percent increase, to the nearest hundredth, of Molly's hair length.
Answers
Find how much it grew:
53 - 20 = 33 inches.
Divide the amount it grew by the original length
33/20 = 1.65
Subtract 1:
1.65 - 1 = 0.65
Multiply by 100 for percent:
0.65 x 100 = 65%
The percent increase is 65%
Which expression is equivalent to 4 x 4 x 4 x 5 x 5 ?
Answers
Answer:
4³×5² or 4³5²
Step-by-step explanation:
This is because there are three consecutive 4s, so you have to put the 4 into exponential form 3 times. So the exponential form for the 4s will be 4³. There are also 2 consecutive 5s so you have to include 2 in the exponential form. So, the exponential form of the 5s is 5². Now you have to somehow multiply them together. You could do this by putting a multiplication sign, (4³×5²) or you could bunch them together and it will mean the same thing (4³5²).

1. Given a right triangle ABC, find the following trigonometric ratios with sides AB = 6, BC = 8 and AC = 10 units. Hint: draw and label your triangle.
a) sin A = 0.13

c) tan A = 0.02
d) sin C = 0.01
e) cos C = 0.99
2. Looking back at question 1,
a) which vertex has the right angle? How do you know? B has a vertex. I know this because angle A and and C connect to angle B, and angle B it the corner of a right angle.
b) what do you notice about sine and cosine of complementary angles? The sine of A is different from the sine of C, and the Cosine of A is the same as the cosine of C

AC is the greatest side, therefore is hypotenuse. AB and BC are legs.
B is 90 deg as the two legs cross at this point.

sin = opposite / hypotenusecos = adjacent / hypotenusetan = opposite / adjacentBC is opposite to A and adjacent to C
AB is adjacent to A and opposite to C

Circle A has center of (6, 7) and a radius of 4, and circle B has a center of (2, 4) and a radius of 16. What steps will help show that circle A is similar to circle B?
Translate circle A using the rule (x + 4, y + 3).
Rotate circle A 45° about the center.
Dilate circle A by a scale factor of 4.
Reflect circle A about the origin.
Answers
Answer:
c took quiz
Step-by-step explanation:
Circle A can be made similar to circle B by dilating circle A by scale factor 4.
Circles can be made similar by performing transformations such as dilations, translation, etc.
The given parameters are:
Circle A
[tex](x,y) = (6,7)[/tex] --- center
[tex]r=4[/tex] --- radius
Circle B
[tex](x,y) = (2,4)[/tex] --- center
[tex]r = 16[/tex] --- radius
To do this, we simply make both circles have the same radius.
Given that:
[tex]r_A=4[/tex] --- radius of A
[tex]r_B = 16[/tex] --- radius of B
Dilating the radius of A by 4 will make both circles have the same radius.
i.e.
[tex]R = r_A * 4[/tex]
[tex]R = 4 * 4[/tex]
[tex]R = 16[/tex]
Now, the new radius of A is 16; same as B
Both circles now have the same radius, means that the circles are similar.

write the linear equation in slope intercept form.
4x+y=1
Answers
Answer: y=-4x+1
Step-by-step explanation:
The slope-intercept form of a line is y=mx+b. Therefore, y needs to be on one side of the equation, and the x term and constant need to be on the other. Rearrange the equation to make this true:
4x+y=1
(4x+y)-4x=1-4x
y=1-4x
y=-4x+1
