Y varies directly with x, and y = 5 when x = 4. What is the value of x when y = 8?

Tomtit [17]

As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)

Find the equation of a straight line passing through the point (0,1) which is perpendicular to the line y=-2x+2

alexandr1967 [171]

Answer:

y = $\frac{1}{2}$ x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-2}$ = $\frac{1}{2}$

The line crosses the y- axis at (0, 1) ⇒ c = 1 , then

y = $\frac{1}{2}$ x + 1 ← equation of perpendicular line

El rodeo has 837 students , El rodeo has 78 more students than hawthorne how many students are there at Hawthorne school later h

elena-s [515]

The number of Elrodeo students is 837.

Let the number of students at Hawthorne be x.

"<span>El rodeo has 78 more students than hawthorne</span>"

this means that

837 = 78 + x
x = 837 -78 = 759

Answer: Hawthorne has 759 students
