Answer:
8x + 2y = 7
2y = -8x + 7
y = -4x + 7/2; this line has slope equal -4
Parallel lines, slope is the same so slope of parallel line is also -4
A. y − 1 = 4(x + 8); slope m = 4....FALSE
B. y = −4x + 15; slope m = - 4....TRUE
C. 16x + 4y = 9; 4y = -16x + 9 so y = -4x + 9/4; slope m = - 4....TRUE
D. y = −4x; slope m = - 4....TRUE

Answer:
The herd migrated a total of 43 3/10 miles and migrated about 14 13/30 miles a day.
Step-by-step explanation:
11 9/10 + 17 1/5 + 14 1/5 =
11 9/10 + 17 2/10 + 14 2/10 =
29 1/10 + 14 2/10 =
43 3/10
43 3/10 divided by 3/1 =
433/10 x 1/3 =
433/30 =
14 13/30
Answer:
2.59
Step-by-step explanation:
Answer: the x intercept is -5 and the y intercept is 25.
Step-by-step explanation:
f(x) = -x^2 + 25
The x intercept is when y is zero and the y intercept is when x is zero.So input zero into the expression and solve for y.
-1(0)^2 + 25 = 25 so the y intercept is 25.
0=-x^2 +25
-25 -25
-25 = -x^2
x^2 = 25
x = -5 or 5
Answer:
4.78 pounds
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 9.2 pound
σ is the population standard deviation = 3.4 pounds
z = 1.3
We are to find x
Hence,
-1.3 = x - 9.2/3.4
Cross Multiply
-1.3 × 3.4 = x - 9.2
-4.42 = x - 9.2
x = -4.42 + 9.2
x = 4.78 pounds.
Therefore the weight of the cat is 4.78 pounds
