Answer:
The slope of the dashed line is 
Step-by-step explanation:
Perpendicular lines and slopes:
If two lines are perpendicular, the multiplication of their slopes is -1.
What is the slope of the dashed line
Perpendicular to a line with slope 4, so:
The slope of the dashed line is
Answer:
First one: function and linear
Second one: function and non-linear
Third one: not a function and linear
Step-by-step explanation:
• The first one is set in the linear function formula y=mx+b, so it is a linear function.
• The second one is a non-linear because functions with exponents have different shapes and can intersect more than once unline linear functions.
• The third one isn't a function but it is linear because it isn't set equal to a variable and it would become a linear if you simply it to isolate a variable.
I hope this helps!!!
178 sundaes were sold in July.
To calculate a percentage, we convert to a decimal by dividing by 100. So 23% = 0.23
145 x 0.23 = 33.35 This is how many more sundaes were sold in July than June. We need to add the 145 sold in June to the increased number to find July’s total.
145 + 33.35 = 178.35
You can’t sell .035/ roughly a third of a sundae, so we round to the whole number.
Um b is maybe 9n + 5 = 15n
um c is maybe 3 - 5 to the third power =3 - 125 = -122 + 7 = -115
maybe you have to add the positive 15n to -115 = -100n
um d is maybe 3b + 2c - 10c = 3b + -8c = -5 <span />
Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = 
, then
cos30° = 
= 
= 
= ( cross- multiply )
2 AC = 12
× = 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
