Answer:
Step-by-step explanation:
a true
b false
Y=mx+b
m is slope
b is y intercept The equation to find the slope is 2nd y-1st y/2nd x- 1st x
2-(-2)/5-0 = 4/5 They m is equal to 4/5 for this equation We know that the y intercept is -2 because you can figure the y intercept when the x is 0
The equation is y=4/5x+0
In each case, you can start by taking the antilog.
21. x = 4^(3/2)
x = 822. 81 = x^(4/3)
81^(3/4) =
x = 2724. 2x - 3 = 6^0
2x = 4 . . . . . add 3
x = 225. 5 - x = 16^(1/2)
5 - 4 =
x = 1_____
You're using the relationship of logarithms:
Answer:
missing side =12 cm
Step-by-step explanation:
let missing side be x
take these ratios
15/10=18/x
do cross multiplication
10*18=15*x
180=15x
180/15=x
12=x
Hello there friend! For part A, an equation that could be used to find the number of bracelets is 12 x 3 + 6n = 60.
Then, for part B, we can subtract the total amount that the bracelets costed, so we would do 3 times 6 which is 18 and then 40 minus 18 equals 22. After that, we can divide 22 by 4 which is 5 and 2 leftover. This tells us that each scarf costs 5 dollars.
Hope this helps! Have a great day!
