It’s the first one because the parabola is open
What are the option? If there are none
then you would take the two fractions and multiply the <span>denominators thus making a new fractions. This is called finding the common denominator.
</span>Ex: 1/2 and 2/3 would have a CD of 6.
<span>So, you would rename them 3/6 and 4/6</span>
To work through a problem like this, first find how many ordered pairs you’re given. In this case, it’s 5.
The answer will always match the amount of ordered pairs given, IF no two x-values are the same. For this scenario, each x-value is unique, so you will have an answer with exactly 5 values. This rules out A and D.
From there, just take the x-value of each ordered pair, list ‘em in order, and you get your answer.
B is the correct answer
no because mathematically 30X10=300 not 900 its would have to be 30X30 to get the product of 900 so therefore no your statement is incorrect

x = 5
m∠C = m∠H = 38 degrees

Given that ABCD ≅ FGHJ
We know that corresponding angles of two congruent
quadrilaterals are equal
Therefore,
m∠A = m∠F
m∠B = m∠G
m∠C = m∠H
m∠D = m∠I
Given,
m∠C = 9x – 7
m∠H = 5x + 13
Since m∠C = m∠H
9x – 7 = 5x + 13
Add 7 to both sides of the equation
9x – 7 + 7 = 5x + 13 + 7
9x = 5x + 20
Subtract 5x from both sides of the equation
9x – 5x = 5x – 5x + 20
4x = 20
Divide both sides of the equation by 4
4x/4 = 20/4
x = 5
To determine the measures of angle C and angle H
m∠C = m∠H
We know that m∠C = 9x – 7
Since x = 5
m∠C = 9(5) – 7
m∠C = 45 – 7
m∠C = 38
Therefore, m∠C = m∠H = 38 degrees
