You have a line:
y=mx+b (slope-intercepted form)
m=slope of this line.
The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.
For example:
y=8x+3
m=8
The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8
Answer: x<-10
Step-by-step explanation:
the < in the math equation means that the number to the right is greater than the number to the left. x can not be -10 it has to be lower (smaller).
Answer:
The function p = 75h represents this situation.
Step-by-step explanation:
We know the equation of linear equation in the slope-intercept form is
where
m = rate of change = slope
b = y-intercept
- Let 'h' be the number of hours
Given that Lian is paid SR 75 per hour.
so the rate of change of slope = m = 75
As there is no initial condition, so b = 0
as
y = mx+b
Now, mapping the information data into the slope-intercept form
Thus, the equation becomes
p = 75h
Therefore, the function p = 75h represents this situation.
VERIFICATION:
Given the equation
p = 75h
for h = 1
p = 75(1)
p = 75
Thus, Liam is paid SR 75 per hour.
Answer:
<em>y = 4(0.75) or y = 3</em>
Step-by-step explanation:
The question is incomplete. Here is the complete question:
<em>The cost saver grocery club sells sheet cakes. Each 1/4 sheet of cake requires 0.75 teaspoon of baking soda. Which expression can be used to find the amount of baking soda needed for a whole cake? Select all the expressions that apply.</em>
<em />
<em>Let the amount baking soda required for a whole cake be y.</em>
<em />
<em>If each 1/4 sheet of cake requires 0.75 teaspoon of baking soda, the expression that can be used to find the amount of baking soda needed for a whole is as shown below;</em>
<em />
<em>1/4 sheet of cake = 0.75 teaspoon of soda</em>
<em>1 sheet of cake = y teaspoon of soda</em>
<em />
<em>cross multiply</em>
<em>1/4 * y = 1 * 0.75</em>
<em />
<em>y/4 = 0.75</em>
<em>multiply both sides by 4</em>
<em />
<em>y/4 * 4 = 0.75 * 4</em>
<em />
<em>y = 4(0.75)</em>
<em />
<em>y = 3 teaspoon of baking soda</em>
