Given equation, y = – 1.3(x + 3)2 – 9 is in slope intercept form.
Step-by-step explanation:
Slope intercept form standard formula:
y = mx + c
where,
y= y intercept
x= x intercept
m = slope
c = constant
We are given:
y = - 1.3(x + 3)2 - 9
y = - 2.6x + 7.8 - 9
y = -2.6x -1.2
So,
Slope = m = -2.6
constant = 1.2
Change the equation to slope intercept form: y= mx + b. m is slope and b is the y-intercept.
7x+4y=10
subtract 7x
4y=10-7x
divide by 4
y=(10-7x)/4
y=10/4-7x/4
simplify
y=5/2-7x/4
swap positions for correct form
y= -7/4x + 5/2
slope= -7/4
Answer:
150
Step-by-step explanation:
its 150 without taxes
color : 40p + 50f + 90
b&w : 15p+20f + 45
p = 26
f = 45
[substitute the values given]
color : 40(26) + 50(45) + 90
b&w : 15(26)+20(45) + 45
[solve the equation]
color : 3380
b&w : 1335
[subtract to see how much ink is saved]
3380 - 1335 = <u>2045</u>
Answer:
110
Step-by-step explanation:
A bump is 180 degrees as well as a triangle. So 90+20=110 and 180-110=70. Meaning 180-70 =110
