determine whether (7,8) is a solution of 7x+9y=11​

Answers

Answer 1

Answer:

(7, 8) is NOT a solution to the equation

Step-by-step explanation:

x = 7 and y = 8 so fill those into the equation

7(7) + 9(8) = 11

49 + 72 = 11

121 = 11

this makes the equation NOT true

So no, (7, 8) is NOT a solution to the equation

A gorilla needs to eat at least 40 pounds of food each day. The zoo feeds the gorilla using canisters that contain 4 pounds of food. The gorilla
has already consumed 28 pounds of food. How many more canisters z of food does the gorilla need to ear? Write your answer as an inequality.

Answers

4z+ 28 ≥ 40

At least would be present as using ≥ or greater than or equal to symbol.

So far the gorilla has consumed 28 pounds of food and each can contains 4 pounds of food.

So: 28 pounds of food/ 4 pounds of food per can= 7 cans consumed

40 pounds needed - 28 pounds consumed= 12 pounds left

12 lbs/ 4 lbs per can= 3 cans left for the gorilla to exceed its goal

Answers

Answer:

61/60

Step-by-step explanation:

answer:

61 / 60

step-by-step explanation:

first, find the common denominator because in order to add fractions, we need the same denominators

5 / 12 + 3 / 5

= 25 / 60 + 36 / 60

= 61 / 60

The melting temperature of tin is about 231˚ C and the melting temperature for oxygen is about -218˚ C. What is the difference in the melting temperatures for tin and oxygen?

a.144
b.13

Answers

Answer:

[tex]D = 512^\circ[/tex]

Step-by-step explanation:

Given

[tex]Tin=231^\circ[/tex]

[tex]Oxygen=-218^\circ[/tex]

Required

The difference in their melting points

This is calculated as:

[tex]D = |Oxygen - Tin|[/tex]

[tex]D = |-281^\circ - 231^\circ|[/tex]

[tex]D = |-512^\circ|[/tex]

[tex]D = 512^\circ[/tex]

The difference is 512 degrees

Based on the cards shown, what is P(pink or even)?

1/5
7/10
9/10​

Answers

Four of them are pink so it’s 4/10 and 2/5

Answer:

7/10

Step-by-step explanation:

To solve this, first find how many of the cards or even. There are 5 even cards out of these 10 cards, so we have the fraction 5/10. Next, we can see that there are 4 pink cards. So, we also have the fraction of 4/10. Then, add these two fractions.

5/10 + 4/10 = 9/10.

But, since the pink 8 card and the pink 10 card are both pink and even, they were counted twice. So, we need to subtract 2/10 from 9/10. This is 7/10.

A movie theatre charges adults $10 to see a movie and charges children $6. If there wereq 120 people who saw a movue and the theatre collected $928, home many attendees were adults

Answers

Answer:

The number of adults tickets sold equals 52.

Step-by-step explanation:

First, we need to establish the system of equations:

x= number of adults tickets sold

y= number of kids tickets sold

10x + 6y= 928

x + y=120

Now, we isolate x in one equation and change it in the other to obtain its value:

x= 120 - y

10(120 - y) + 6y = 928

1,200 - 10y + 6y = 928

272 = 4y

68 = y

x= 120 - 68= 52

The vertex of the graph of g is 2 units below the vertex of the graph of f.

The vertex of the graph of g is 2 units to the left of the vertex of the graph of f.

Answers

Answer:

The vertex of the graph of g is 2 units above the vertex of the graph of f.

Step-by-step explanation:

The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x). Then the correct option is A.

What is a function?

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The graph of f(x) = x² was transformed to create a graph g(x) =f(x)+2.

Then the g(x) will be

g(x) = x² + 2

We know that the graph of the g(x) shifted to 2 units upward because we added 2 in the function.

The graph is shown.

The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x).

Thus, the correct option is A.
