Make y the subject of the formula x=a-2by²
Answer:
y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]
Step-by-step explanation:
Given
x = a - 2by² ( add 2by² to both sides )
x + 2by² = a ( subtract x from both sides )
2by² = a - x ( divide both sides by 2b )
y² = [tex]\frac{a-x}{2b}[/tex] ( take the square root of both sides )
y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]
Answer:
[tex]y = a - x \di2b[/tex]
Step-by-step explanation:
[tex]2b {y }^{2} = a - x[/tex]
[tex]2b {y}^{2} \div 2b = a - x \ \div 2b[/tex]
[tex] {y}^{2} = a - x \div 2b[/tex]
[tex]y = \sqrt{a - x \div 2b} [/tex]

Answer:
[tex]\frac{5}{14}[/tex]
Step-by-step explanation:
It's important to note here that fractions are just another way of representing division.
Therefore, [tex]\frac{\frac{1}{4}}{\frac{7}{10}}[/tex] is the same thing as [tex]\frac{1}{4} \div \frac{7}{10}[/tex].
To divide two fractions, we multiply by the reciprocal.
[tex]\frac{1}{4} \cdot \frac{10}{7}[/tex]
We can now multiply the numerators and denominators.
[tex]1\cdot 10 = 10\\7 \cdot 4 = 28\\\\\frac{10}{28}[/tex]
We can simplify this fraction by dividing both the numerator and denominator by 2.
[tex]10\div 2 = 5\\28 \div 2 = 14[/tex]
So, [tex]\frac{5}{14}[/tex].
Hope this helped!

Jose has $178.74 in his checking account. He wrote checks for $36.52, $18.92, and $25.93. He also deposited $300.00, $100.00, and $205.16. What is the final balance in Bob's checking account?V
Answer:
$702.53
Step-by-step explanation:
Start with Jose's initial balance.
[tex]178.74[/tex]
He wrote checks, so we have to subtract the total amount the checks were worth. Let's first add the three amounts.
[tex]36.52+18.92+25.93[/tex]
Solve.
[tex]81.37[/tex]
Subtract the total amount of the checks from Jose's initial balance.
[tex]178.74-81.37[/tex]
Solve.
[tex]97.37[/tex]
The amount above is now what is in Jose's checking account.
But, he also deposited money, meaning he put money in his checking account. Now, let's add the three amounts he deposited.
[tex]300.00+100.00+205.16[/tex]
Solve.
[tex]605.16[/tex]
The amount above is what Jose adds to his checking out.
Add the total value of the deposited money and his new balance.
[tex]605.16+97.37[/tex]
Solve.
[tex]605.16+97.37=702.53[/tex]

If a + b = 10, and ab = 16, then find the value of the following: i .a2 + b2 ii. a3 – b3
Answer:
a² + b² = 68
a3 + b3 = 520
Step-by-step explanation:
Given :
a + b = 10 (1)
ab = 16 (2)
A. Find a² + b²
(a + b)² = a² + 2ab + b² (3)
Substitutite the values of (1) and (2) into (3)
(10)² = a² + 2(16) + b²
100 = a² + 32 + b²
Subtract 32 from both sides
100 - 32 = a² + b²
a² + b² = 68
B. a^3 + b^3
(a + b)^3 = a^3 + b^3 + 3ab(a + b)
(10)^3 = a^3 + b^3 + 3*16(10)
1000 = a^3 + b^3 + 480
a^3 + b^3 = 1000 - 480
a3 + b3 = 520

Is there a dilation that maps shape II onto shape I? If so, what is the scale factor and is it an enlargement or a reduction?
Shape II was dilated by a scale factor of 1/3 to form shape I. This is a reduction since the scale factor is less than 1.
What is transformation?Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, rotation and dilation.
Shape II was dilated by a scale factor of 1/3 to form shape I. This is a reduction since the scale factor is less than 1.
Find out more on transformation at: https://brainly.com/question/4289712
#SPJ1
Answer: A dilation will map shape I onto shape II. The bottom left coordinate of shape I is (1, 1) and the bottom left coordinate of shape II is (3, 3). So, to get the corresponding coordinates of shape II, multiply the coordinates of shape I by 3. This is true for every set of coordinates. So, the scale factor is 3. Because the scale factor is 3, which is greater than 1, the dilation is an enlargement.

[tex]3x=9[/tex]
Divide both sides by 3:
[tex]\frac{3x}{3}=\frac{9}{3}[/tex]
