Answer:
its a change of -3 per hour.
Step-by-step explanation:
I do not know the formula for the equation you speak of, but the change per hour is that it is going down by 3 every hour. 10-3=7-3=4
4-3=1
1-3= -2.
will give brainliest: how do i solve this??
Answer:
Step-by-step explanation:
-y = -5x + 7
y = 5x - 7
perp.: -1/5
y - 2 = -1/5(x + 8)
y - 10/5 = -1/5x - 8/5
y = -1/5x + 2/5

Given that ℓ1∥ℓ2 and the measure of ∠c = 44°, find the measures of angles a and b.
m∠a =
°
m∠b =
°
Answer:
<a = 44 degrees
<b = 136degrees
Step-by-step explanation:
From the given diagram;
<a = <c (alternate interior angle)
Since <c = 44 degrees, hence <a = 44 degrees
Also the sum of a and b is supplementary hence;
a + b = 180
44 + b = 180
b = 180 - 44
b = 136degrees
Hence m<b =136degrees

Answer:
x=7
Step-by-step explanation:
Step 1: Cross-multiply.
9(x−4)/6=x+2/2
9(x−4)*(2)=(x+2)*(6)
18x−72=6x+12
Step 2: Subtract 6x from both sides.
18x−72−6x=6x+12−6x
12x−72=12
Step 3: Add 72 to both sides.
12x−72+72=12+72
12x=84
Step 4: Divide both sides by 12.
12x/12=84/12

The country of Sylvania has decided to reduce the number of its illiterate citizens by 3/5 each year. This year there are 9000 illiterate people in the country.
Write a function that gives the number of illiterate people in Sylvania, P(t), t years from today
Answer:
P(t)= 9000(0.4)^t
Step-by-step explanation:
Generally, we have an exponential function as follows;
P(t)= I(1 - r)^t
This case represents a decay ( decrease in value)
from what we have;
I represents the initial value, whereas r is the rate of change
From the question, we have that the change rate is the fraction 3/5
Writing this as a decimal, it is 0.6
substituting this back into the equation, we have;
P(t)= I(1-0.6)^t
P(t)= I(0.4)^t
I in this case is 9,000
So we have it that;
P(t) = 9000(0.4)^t

Answer:
x should be 55
Step-by-step explanation:
the acute angle is 55 and we know that the whole horizontal is 180 so calculate 180-55 to find the obtuse angle which is 125. Then subtract 70 from that to isolate for x and you get 55.
i need this question for algebra 1 please!
Answer: C
Step-by-step explanation:
[tex]A = \frac{1}{2} (b+c)h\\[/tex] -> This is the original equation
[tex]\frac{A}{h} = \frac{1}{2} (b+c)\\[/tex] -> Divide by h on both sides
[tex]2\frac{A}{h} = b+c\\[/tex] -> Multiply both sides by 2
[tex]2\frac{A}{h}-b = c\\[/tex] -> subtract b from both sides
What is measure of the missing angle? HELP
(2x - 7) + ( x + 4) = 90°
2x + x - 7 + 4 = 90°
3x - 3 = 90°
3x = 90 + 3
3x = 93
x = 93/3
x = 31°
▪2x - 7
= (2 . 31) - 7
= 62 - 7
= 55°
▪x + 4
= 31 + 4
= 35°

Olivia and Jamie share
sweets in the ratio 3: 7. If
Olivia gets 27 how many
sweets does Jamie get?
Answer:
jamie gets 63
Step-by-step explanation:
27(olivias sweets)/3=9
9*7=63
=63
Answer:
63
Step-by-step explanation:
you have set them up so you can cross multiply.
(3 * x) = (7 * 27)
3x = (189)
to solve for x we need to isolate the variable, so divide both sides by 3:
x = 63

A father is 28 years solder than his daughter. In six years, he will be 3 times her age. Find their present ages.
Please use an algebraic equation to solve, and show your working. A photo of your working out on paper is also fine as long as I can read it.
Answer: father:45
Daughter:17
Step-by-step explanation:
Present
Father (X+28)yrs
Daughter X yrs
After 6 years father will be (X+28)+6= 3x
28+6=3x-x
34=2x
X=17yrs=daughter
Father=28+17=45yrs
