Answer:
-21
Step-by-step explanation:
I used the backward method
She adds 8 to get 5.
So we start with 5 and subtract 8
5-8 = -3
She divides by 7 but since we are using the backwards method, we have to multiply.
-3*7= -21
After that, we can check our answer
Krutika was thinking of -21
-21/7= -3
-3+8= 5
-21 is the answer
Hope this helps!

Enter an expression in the box to write a quadratic function given the vertex (7,-4) and the point (5, 8).
Answer:
f(x) = 3(x - 7)² - 4Step-by-step explanation:
The vertex form of an equation of the parabola:
f(x) = a(x - h)² + k
the vertex is (7, -4) ⇒ h = 7, k = -4
so:
f(x) = a(x - 7)² + (-4)
f(x) = a(x - 7)² - 4
The parabola goes through the point (5, 8) ⇒ x=5, f(x)=8
8 = a(5 - 7)² - 4
8 = a(-2)² - 4
+4 +4
12 = 4a
÷4 ÷4
a = 3
It means the equation of the parabola in vertex form:
f(x) = 3(x - 7)² - 4

What is 1 2/3m + 2 = 2 1/6? Solve for m and show your work please
Answer:
Step-by-step explanation:
1+2/3m+2=2+1/6
We move all terms to the left:
1+2/3m+2-(2+1/6)=0
Domain of the equation: 3m!=0
m!=0/3
m!=0
m∈R
We add all the numbers together, and all the variables
2/3m+1+2-(1/6+2)=0
We add all the numbers together, and all the variables
2/3m+3-(1/6+2)=0
We get rid of parentheses
2/3m+3-2-1/6=0
We calculate fractions
There is no solution for this equation
Answer: m = 1/10
Step-by-step explanation:
1 2/3m + 2 = 2 1/6
Firstly, subtract 2 from both sides to get m alone:
1 2/3m = 1/6
Now, to get m alone, divide both sides by 1 2/3:
m = 1/10

Is PQS congruent to RQS by HL? If so, name the legs that allow the use of HL.
Answer:
Yes.
RS ≅ PS
QS ≅ QS
Step-by-step explanation:
The Hypotenuse-Leg Congruence Theorem states that when the hypotenuse and one leg of a Right-angled triangle are congruent to that of another Right-angled triangle, the two Right-angled triangles are therefore congruent.
In the diagram given, the hypotenuse (RS) and a leg (QS), of ∆RQS is congruent to the hypotenuse (PS) and a leg (QS) of ∆PQS. Therefore, ∆PQS is congruent to ∆RQS by HL Congruence Theorem.
Yes, PQS congruent to RQS by HL is true statement according to the diagram.
Hence :
RS ≅ PS
QS ≅ QS
Step-by-step explanation:
Given information:
The hypotenuse RS and PS
And leg QS.
Hypotenuse-Leg (HL) theorem:
The H-L theorem states that If, the hypotenuse and one leg of a Right-angle triangle are congruent to that of another right angle triangle then the given two right angled triangle will be congruent.
As, we can see in the given diagram the hypotenuse (RS) and the leg (QS) of triangle ΔRQS is congruent to hypotenuse (PS) and leg (QS) of triangle ΔPQS.
Hence , we can say that the ΔPQS is congruent to ΔRQS by H-L Congruent theorem.

A kids' movie ticket costs $5.25.
1. One day, 200 kids' tickets were purchased. What was the total cost of those tickets?
2. Ift is the number of kids' tickets purchased, and c is the total cost of those tickets,
write an equation that relates c tot.
3. Another day, the total cost of kids' tickets was $813.75. How many tickets were
purchased that day?
Answer:
1. $1050
2. $5.25t = c.
3. $813.75 ÷ 5.25 = 155.
Step-by-step explanation:
For the first day, 200 kid tickets were purchased. We know that a singular movie ticket is $5.25. From this information, I know I have to multiply.
200 x 5.25 = 1050.
The answer to number one is $1050.
So t will be the variable that represents the number of kid's tickets and c is the total cost, from this equation, I would create this equation:
$5.25t = c.
I put 5.25 down because that is the cost of a singular child ticket. It would be multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).
The answer to number 2 is $5.25t = c.
Another day, the total cost of the tickets were $813.75. One kid movie ticket is $5.25, so this calls for division.
$813.75 ÷ 5.25 = 155.
The total amount of tickets that were purchased that day was 155 child tickets.
The total amount of tickets that were purchased that day was; 155 child tickets.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that 200 kid tickets were purchased. We know that a singular movie ticket is $5.25.
200 x 5.25 = 1050.
The total cost of those tickets is $1050.
Let t be the variable that represents the number of kid's tickets and c is the total cost, from this equation:
$5.25t = c.
Now multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).
The answer is $5.25t = c.
On another day, the total cost of the tickets was; $813.75. One kid movie ticket is $5.25 thus;
$813.75 ÷ 5.25 = 155.
The total amount of tickets that were purchased that day was; 155 child tickets.

h(-4) = 4(-4) + 1
h(-4) = -16 + 1
h(-4) = -15
h(-3) = 4(-3) + 1
h(-3) = -12 + 1
h(-3) = -11
h(1) = 4(1) + 1
h(1) = 4 + 1
h(1) = 5
h(2) = 4(2) + 1
h(2) = 8 + 1
h(2) = 9
h(3) = 4(3) + 1
h(3) = 12 + 1

A car rental agency charges a base fee of $50 plus an additional charge of $0.40 for every mile driven. The total charge, c, is given by the equation. c = 50 + 0.40m, where m represents the miles driven. When Mr. Sims rented a car, his total charge was $178.00. How many miles did Mr. Sims drive the car? *
Answer:
Mr. Sims drove 320 miles.
Step-by-step explanation:
c = 50 + 0.40m
178 = 50 + 0.40m
128 = 0.40m
m = 320

Diseases tend to spread according to the exponential growth model. In the early days of AIDS, the growth factor (i.E. Common ratio; growth multiplier) was around 1.9. In 1983, about 1800 people in the U.S. Died of AIDS. If the trend had continued unchecked, how many people would have died from AIDS in 2006?
Answer:
4640933300 people would have died from AIDS in 2006.
Step-by-step explanation:
Let the equation that models the growth in mortality because of AIDS be,
[tex]A_n=A_0(1+r)^n[/tex]
Where [tex]A_n[/tex] = Number of deaths after n years
[tex]A_0[/tex] = Deaths in first year
(1 + r) = Growth factor
n = number of years
Now we substitute the values in the equation,
[tex]A_0=1800[/tex]
(1 + r) = 1.9
n = Number of years = 2006 - 1983 = 23 years
[tex]A_n=1800(1.9)^{23}[/tex]
= 1800(2578296.28)
= 4640933300
Therefore, with the same death rate 4640933300 people would have died from AIDS in 2006.

Lake Okeechobee's water level was at sea level in April. In May, the lake's level rose 4 inches and in June it rose 2 more inches. As a result of no rain, the lake's level fell 5 inches in July and 3 more inches in August. Select all the expressions that describe this situation. 4 – 5 4 + 2 – 5 – 3 4 + 2 – (5 – 3) 4 + 2 – (5 + 3) 4 + 2 – (– 5) – (– 3) 4 + 2 + (– 5) + (– 3)
Step-by-step explanation:
If the lake's level rose 4 inches and in June it rose 2 more inches, the total amount of distance that he rose is (4+2).
Also if the lake's level fell 5 inches in July and 3 more inches in August as a result of no rain, then the total amount of fall will be (5+3).
Change in height of the lake = total rise in distance - Total fall in distance
Change in height of the lake = (4+2) - (5+3) = (5+3) - (4+2) {commutative law}
open the parenthesis
(4+2) - (5+3)= 4+2-5-3 (note that minus times plus will give minus)
Hence the expressions that best describe this situation are;
1. (4+2) - (5+3)
2. (5+3)-(4+2)
3. (4+2) - 5 -3
