Perry surveyed 60 students at her school and found that 0.45 of the students she surveyed said their favorite class is math. Ano
Phantasy [73]
<span><span>1.       </span>Perry surveyed 60 students at her school.
=> 0.45 of the students said that their favorite subject is math
=> 0.45 x 100 = 45%
Thus, 45 % of 60:
=> 60 * .45 = 27
35% of the student said their favorite is science:
=> 35% / 100 = 0.35
=> 35% 0f 60 equals:
=> 60 * .35 = 21
Thus, 27 – 21 = 6 of the student said that they love math over science.

Find the equation of a line passing through (3, -5) that is parallel to 2x+6y=10
Zina [86]

Answer:

The equation of the line would be y = -1/3x - 4

Step-by-step explanation:

In order to find this, we first need to find the slope of the original line. We do this by solving for y.

2x + 6y = 10

6y = -2x + 10

y = -1/3x + 5/3

Now that we see the slope as -1/3, we know the new line will have the same slope thanks to the definition of parallel lines. So, we can use this slope and the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - -5 = -1/3(x - 3)

y + 5 = -1/3x + 1

y = -1/3x - 4

A quadratic equation with real coefficients and leading coefficient 1, has x = -bi as a root. Write the equation in general form
andrey2020 [161]
<span>The general form of quadratic equation with real coefficients and leading coefficient 1, has x = -bi as a root
=> x = <u>-b  + </u></span><u>√ b^2 – 4 ac</u><span>
                    2a

It is also written as:
=> ax^2 + bx + c = 0

Quadratic equation involves unknown numbers which is x, the numbers which a, b and c are called coeffecients.
There are also quadratic factorization where you factor the polynomial give to be able to get the value of the equation.</span>

Do the ratios 9/4 and 11/6 make a proportion please explain. Thank You!
svetoff [14.1K]
No they're not proportionate because 9 divided by 4 = 2.25 and 11 divided by 6 is 1.83 so they're not the same in value
