Step-by-step explanation:
f(x)=4x+3. f(x)=27
so 27=4x+3
27-3 =4x
24=4x
x=24/4
x=6
Answer:1st one 2nd one and 8th
Step-by-step explanation:
Answer:
y=1/2x
Step-by-step explanation:
Equations of lines are written in slope-intercept form:
y=mx+b
where m is the slope and b is the y intercept.
The slope is 1/2 and the y-intercept is 0. Therefore, we can substitute 1/2 for m and 0 for b.
y=1/2x+0
Adding 0 onto the end doesn't change the equation and doesn't serve a purpose, so it can be removed from the end of the equation.
y=1/2x
The equation is: y=1/2x
Answer:8:24
Step-by-step explanation:
So since it is 1:3 and 2 dozen is 24 so 24 divided by 3 = 8 so now it’s 8:24
Answer:
Step-by-step explanation:
y = -3x - 3
m = -3_______
b = -3________
y = 2x + 2
m = 2_______
b = _2_______
SOLVE NOW : -3x - 3 = 2x + 2
- 5x = 5
x = -1
subst in y : y = 2(-1)+2 = 0
the solution is : ( - 1 , 0 )
y = -3x- 3 an equation for the line 'red'
y = 2x+2 an equation for the line 'bleus'
