I think of a number, double it and subtract 1 and then square the answer. The result is 64. What could the number be? Give two possible answers please.

Answers

4.5

Maybe I’m missing something, but from how I understand this question 4.5 is the only possible answer.

- 4.5 doubles to 9
- subtract 1 from 9 to get 8
- square 8 for the result of 64

(This is just my logic, but maybe my thought process can help you!)

Find the unknown angle​

Answers

Answer:

77 degrees

Step-by-step explanation:

Right triangles always add up to 180 degrees. We know that one angle is 23 degrees, angle A is missing, and the last angle is a right angle which is equal to 90 degrees. Knowing what we know, we must subtract the two known angles from 180 to get angle A.

180 - 90 = 90

90 - 23 = 77

Angle A is equal to 77 degrees.

Simon wants to find out which shop has the best frozen fruit drink in town. How could Simon conduct a survey with a sample that is representative of the population

Answers

Answer:

Step-by-step explanation:

The best way to do this would be to choose a random number of individuals that have bought a frozen fruit drink to survey. Then this same number of individuals should be surveyed in every single shop in the town. This would allow you to gather data from all of the shops and make sure that the sample is completely representative of the population as long as the individuals are chosen completely at random without introducing any external bias to the choice.

Select the correct answer.
Solve the system of equations.

y = x + 3
[tex]y=x^{2} +7x+8[/tex]

A.
(-1,-4) and (-5,-8)
B.
(-1,2) and (-5,-2)
C.
(1,4) and (5,8)
D.
(-1,-2) and (-5,2)

Answers

Answer:

B.  (-1,2) and (-5,-2)

Step-by-step explanation:

Substitute x + 3 in for y in the second equation.  you get

[tex]x + 3 = x^{2} + 7x + 8\\x^{2} + 6x + 5 = 0[/tex]

(x + 1)(x + 5) = 0

x + 1 = 0    or  x + 5 = 0

x = - 1       or     x = -5

Using the first equation, let x = -1  and x = -5 in order to get the corresponding values for y

y = -1 + 3 = 2           and y = -5 + 3 = -2

So, B is the correct answer.

Write a linear equation that gives the rule for this table.
Hint: Linear Functions are of the form y=mx+b

Answers

Answer:

y=x

Step-by-step explanation:

If we look at this then this is a y=mx+b graph

first lets find the rise/run

so rise = how much it goes up and run = how much it goes right or left

the rise/run of this graph is 1 because each time it goes one up it goes one right.

B= y intercept and the y intercept is 0

So it is y=1x+0 or y=x

answer = y=x

Robin was given a $40 monthly allowance. She wants to go to the movies as many times as possible and have at least $12.50 left at the end of the month to go to a concert. A movie ticket costs $5. How many times can she go to the movies?

Answers

Answer:

5 times

Step-by-step explanation:

5*5 is 25

40-25=15$ left

any more movie tickets would be too much money spent

If Robin was given a $40 monthly allowance. She wants to go to the movies as many times as possible and have at least $12.50 left at the end of the month to go to a concert. A movie ticket costs $5. Then she can go six times to the movies.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Robin was given a $40 monthly allowance.

She wants to go to the movies as many times as possible and have at least $12.50 left at the end of the month to go to a concert.

The amount spent on movies

40-12.5

$27.5

A movie ticket costs $5.

We need to find how many times can she go to the movies.

To find this we need to divide $27.5 by 5

$27.5/5=5.5

Robin can go 6 times to the movies.

What is the slope and y-intercept of the following equation: y = -4 +2x

Answers

Answer:

slope = 2, y- intercept = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4 + 2x , that is

y = 2x - 4 ← is in slope- intercept form

with slope m = 2 and y- intercept c = - 4
