Answer:
D. {4, 0, -3.5}
Step-by-step explanation:
domain (x) = {-3, 1, 4.5}
y= -x + 1
substituting domain/x-values into y= -x + 1
x= -3
y = -(-3) + 1
= 3+1
= 4
x= 1
y = -(1) + 1
= 0
x = 4.5
y = - (4.5) + 1
= -3.5
therefore, range ={4, 0, -3.5}
Write the equation of the line with a slope of -2/5 and goes through the point
(-15, 5)
Answer:
y=[tex]-\frac{2}{5} x[/tex]-1

At Alpha's school, lunches cost $2 and the cafeteria cashiers begin to warn you when your account falls below $10. If Alpha has $38 in her account, in how many days will the warnings begin and how long will they continue? Write the inequality to express this.
Answer:
the warnings will begin in 12 days and last for 5 days
Step-by-step explanation:
38-10=28, 28÷2=12, 10÷2=5, so you get 12 and 5
what’s 2/7x-7 = 9x-4
Step-by-step explanation:

[tex] \frac{2}{7} x - 9x = - 4 + 7[/tex]
[tex] \frac{2}{7} x - \frac{63}{7} x = 3[/tex]

The school that Eduardo goes to is selling tickets to a fall musical. On the first day of ticket salesthe school sold 3 adult tickets and 7 student tickets for a total of $81. The school took in $94 onthe second day by selling 4 adult tickets and 7 student tickets. Find the price of an adult ticketand the price of a student ticket.A) adult ticket: $6, student ticket: $13B) adult ticket: $13, student ticket: $6C) adult ticket: $17, student ticket: $9D) adult ticket: $19, student ticket: $8
Answer: B) adult ticket: $13, student ticket: $6
Step-by-step explanation:
Let adults tickets be written as a
Let student tickets be written as s
We then use the information given in the question to form equation. This will be:
3a + 7s = 81 .......... equation i
4a + 7s = 94 .......... equation ii
Subtract equation i from ii
a = 13
Adult tickets cost $13
From equation i
3a + 7s = 81
We put the value of a = 13
3(13) + 7s = 81
39 + 7s = 81
7s = 81 - 39
7s = 42
s = 42/7
s = 6
Students ticket cost $6
y- 22= 89
y-22 + __ = 89 +22
y= __

Lightening Pizza has a special: If customers order 4 pizzas, each pizza will cost $4.44. Mr.Peele orders 4 pizzas and wants to tip the driver 20% of the cost of the order. How much should Mr. Peele tip, round up to the nearest cent?
Answer:
21.31
Step-by-step explanation:
First do 4.44x4 then you get 17.76
and 20% of 17.76 is 3.552
you add 17.76 and 3.552 to get 21.312 which you round to the hundrenth which is 21.31

Change 5x+1=4y+7 to slope intercept form ( y=mx+b)
Answer:
Step-by-step explanation:
5x + 1 = 4y + 7
5x - 4y = 7 - 1
-4y = -5x + 6
-4y/-4 = -5x/-4 + 6/-4
y = 5/4x - 6/4
y = 5/4x - 3/2
Answer:
Work shown below!
Step-by-step explanation:
5x + 1 = 4y + 7 to y = mx + b
5x + 1 = 4y + 7
Subtract 7 from both sides;
5x - 6 = 4y OR 4y = 5x - 6
4y = 5x - 6
Divide both sides by 4;
[tex]y=\frac{5}{4}x-\frac{6}{4} \\\\y=\frac{5}{4}x- \frac{3}{2}[/tex]

What is the value of x in the question 1/2(x+6)=18
Answer: x= 30
Step-by-step explanation:
Simplify both sides of the equation. 12(x+6)=18(12)(x)+(12)(6)=18(Distribute) 1x+3=18
Step 2: Subtract 3 from both sides. 12 x+3−3=18−312 x=15
Step 3: Multiply both sides by 2. 2*(12x)=(2)*(15)
x=30
Answer:
x=30

3. What is the image of (-6,5) after a reflection over the y-axis?
a small water bottle holds 75% as much as a large water bottle.
if the small holds 36 units, how much does the large hold?
Capacity of larger bottle = 48 units
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Given,
small bottle holds 36 units of water
Let the large bottle holds x units of water
According to the question,
capacity of small bottle = 75% of capacity of large bottle
36 = 75/100 × x
⇒ x = 36 × 100 / 75
⇒ x = 3600/75
⇒ x = 48 units
Hence the larger bottle holds 48 units of water.

Marisol is given the following three lengths of a possible triangle: 1, 2 and 7. Would these side lengths form a triangle?
Yes, because 1 + 2 > 7, 2 + 7 > 1 and 7 + 1 > 2.
Yes, because 1 + 2 1 and 7 + 1 is greater than 2.
No, because 1 + 2 < 7 and in order for side lengths to meet the Triangle Inequality Theorem, any two side lengths must be greater than the third side when added together.
Answer:
no because 1+2<7. To form a triangle any two lengths have to be greater than third one
