Step-by-step explanation:
if the graph of f(x) = x is shifted up 9 units, what would be the equation of the new graph?
Answer:
x+9
Step-by-step explanation:
f(x) = x, going up 9
that is y=x, going up 9
if you wnat to go up, subtract 9 from y
y -9 = x
y=x+9
convert back to f(x)
f(x) = x+9
Find the unknown side length X.

Recall the formula V= 72.
Mold A
Mold B
Mold C
Mold D
Answer:
mold B
Step-by-step explanation:
The molds are of cylindrical shape. The volume of a cylinder is given by:
Volume = πr²h
where r is the radius and h is the height.
For mold A: diameter = 2 inches, hence radius = 1 inch. Height = 7 inches
volume = π(1²)7 = 7π in³
For mold B: diameter = 2 inches, hence radius = 1 inch. Height = 4 inches
volume = π(1²)4 = 4π in³
For mold C: diameter = 3 inches, hence radius = 1.5 inch. Height = 3 inches
volume = π(1.5²)3 = 6.75π in³
For mold C: diameter = 4 inches, hence radius = 1.5 inch. Height = 3 inches
volume = π(2²)3 = 12π in³
Therefore mold B has the smallest volume

X=-8
Step-by-step explanation:
3x-4=7×-4
3x-4=-28
3x=-28+4
3x=-24
x=-24/3
x=-8
Answer:
[tex]x =-8[/tex]
Step-by-step explanation:
Hello!
Remove the fraction by multiplying both sides by 7. Solve for x by isolating the variable.
Solve for x[tex]\frac{3x - 4}{7} = -4[/tex][tex]3x - 4 = -28[/tex][tex]3x = -24[/tex][tex]x = -8[/tex]The value of x is -8.

one positive integer is 2 less than another. The product of the two integers is 24. what are the two integers?
If one is positive we can conclude that the other is also positive
Positive*positive=positive(24)
The product of the two numbers is 24
And the smaller number is less than the greater number by 2
Factors of 24=1*24,2*12,3*8,4*6.
The only pair with the diffrence of two is 4*6
Therefore the two integers are 4 and 6

Answer: 3t12=15t this is what my tech told me
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
these are vertical angles so they equal each other
3t + 12 = 66
3t = 66 - 12
3t = 54
t = 54 ÷ 3
t = 18
At the start of a hike, a hiker was at an elevation of -50 feet (where 0 represents sea level). The hiker climbs at a rate of 15 feet per minute. a. Write an inequality that represents t, the number of minutes after the start of the hike, when the hiker’s elevation was higher than 5 feet above sea level.
Answer:
15t - 50 > 5Step-by-step explanation:
Initial point = -50 ftClimbing rate = 15 ft / minTime = tRequired inequality:
15t - 50 > 5Solution:
15t > 55t > 55/15t > 3 10/15 = 3 40/60 min = 3 min 40 secondsAnswer:
Solution given:
Initial point = -50 ft
Climbing rate = 15 ft/min
Time = t(let)
So Required inequality:
15t-50 > 5
adding 50 on both term
15t> 55
dividing both term by 15
t > 55/15
t> [tex] 3 \times \frac{10}{15} [/tex]=
[tex] 3 \times \frac{40}{60} [/tex]= 3 min 40seconds is your answer

Tom decides to pick up some pizzas and drinks for his family. He notices that the pizza costs the same as 7 drinks. The 2 pizzas and 8 drinks cost $33. What is the price of each item?
Answer:
Drinks = $1.5
Pizza = $10.50
Step-by-step explanation:
let d = drinks
p = pizza
p = 7d equation 1
2p + 8d = 33 equation 2
from equation 1, we know the price of one pizza, the price of two pizzas can be determined by multiplying by 2
2p = 7d x 2 = 14d eqn 3
Substitute for 2p in equation 2
14d + 8d = 33
22d = 33
Divide both sides of the equation by 22
d = $1.5
Substitute for d in equation 1
p = 1.5 x 7 = $10.5
