The amount charged is an illustration of a linear equation.
Tina charges $39 for 4 hours
The given parameters are:
[tex]Base = 15[/tex] --- amount charged for the first hour
[tex]Rate = 8[/tex] --- amount charged for the extra hours
If Tina babysits for 4 hours, it means that:
She will charge $15 for the first hour$8 for the extra 3 hoursSo, the total charges is:
[tex]Total = 15 + 3 \times 8[/tex]
[tex]Total = 15 + 24[/tex]
[tex]Total = 39[/tex]
The ordered pair is (4,39)
It means that:
She charges $39 for 4 hours

Which graph represents the solution set of the system of inequalities?
Answer:i think is A
Step-by-step explanation:
“To find 623, I can just take the value of 613 then either multiply it by 12 or divide it by 2.” Do you agree with her? Explain why or why not.
Step-by-step explanation:
613 and 623 are very close values.
multiplying by 12 or a division by 2 changes the starting value drastically.
so, this cannot be right.
and dividing 613 by 2 also makes it even smaller. but to get 623 we need to make it bigger.
so, therefore, even without actually calculating the numbers, the statement is proven false.

Step-by-step explanation:
4. In the figure, points A, B, and Clie in plane Z. Which of the following postulates can be used to show that A and B are collinear?
O Through any two points, there is exactly one line.
O Through any three points not on the same line, there is exactly one plane.
O If two lines intersect, then their intersection is exactly one point.
o If two planes intersect, then their intersection is a line.
Collinear points are points that lie on the same line.
The postulate to prove that A and B are collinear is: (a) Through any two points, there is exactly one line.
From the question, we understand that:
A, B and C are in plane ZA and B are collinearFor A and B to be collinear, then:
A line must pass through A and B, in such a way that points A and B lie on that line
Because only one line can pass through any two points, the appropriate postulate to use is: (a) Through any two points, there is exactly one line.

Explain or show work to prove that the following equation is true.6 x 8 = 3 x 2 x 2 x 2 x 2
Answer:
see explanation
Step-by-step explanation:
To prove the equation id true, solve both sides and if they are equal then the equation is true.
left side = 6 × 8 = 48
right side = 3 × 2 × 2 × 2 × 2
= 6 × 2 × 2 × 2
= 12 × 2 × 2
= 24 × 2
= = 48
Since both sides are equal then the equation is true
Write the equation of a line with a slope of 3 that passes through the point (3, -4) in point-slope
form. Then change to slope-intercept form.
Step-by-step explanation:
Point slope for can be written as [tex]y-y_{1} =m(x-x_{1} )[/tex]
Where your point used is ([tex]x_{1} ,y_{1}[/tex]) and your slope is m.
Here we get y-(-4)=3(x-3)
y+4=3(x-3)
For slope-intercept form just move the 4 to the other side.
y=3x-13

In this lesson you discovered the Angle Blsector Conjecture. Write the converse of the Angle Blsector Conjecture. Do you think it's true. Why or why not?
Answer: The converse is that if a point is on the interior of an angle and is equidistant from both sides of the angle, then the point lies on the angle bisector. This makes sense since the distance from a point and a side of the angle is a perpendicular line connecting the point to a side. And since it is equidistant from both sides, the perpendicular lines have to be congruent, it make sense if the point is on the angle bisector, the traingles would be congruent.

Answer:
x + y =5 .......eqn (1)
x - y =3 .......eqn(2)
using substitution method
x + y = 5
-
x - y = 3
0 + 2y=2
y = 2/2
y = 1
substitute y in egn(1)
x + 1 = 5
x = 5-1
x = 4
then (x, y) = (4,1)
There are 20 black, 15 white, 12 green, 12 red, 9 blue, and 2 yellow candies in a box. How many candies should you take (without looking at them) to be sure that you have at least 3 candies the same color
Answer:
13
Step-by-step explanation:
Because the problem says to make sure we have at least 3 candies of the same color, we have to think about the worst-case scenario. To get the worst-case scenario, we need to have the largest amount of candies taken before fulfilling the statement that 3 candies have the same color, so we take 2 black, 2 white, 2 green, 2 red, 2 blue, and 2 yellow candies. This sums to 12, and you have the worst case scenario here. But wait, you've picked only 2 of each candy. You have to pick one more candy to make sure you have 3 candies of the same color, so the answer is 12 + 1 = 13 candies.

In March, Isaiah and Freddie had the same amount of money in their savings accounts. In April, Isaiah deposited $210 into his account. Freddie increased the money in his account by 15%. When they compared their balances, they found that they were still equal.
How much money did they both have in their accounts in March?
Enter your answer in your box.
Answer:
let the amount deposited by each of them in march be m.
in April, Isaiah deposited 210$, this means the amount in his account became m+210
Freddie increased the amount by 15%, this means that the amount of money in his account became: m+0.15m
since both values are still equal, we will equate both equations and solve for m.
m+210 = m+0.15m
0.15m = 210
m = 1400$

Robin works as a customer service representative. She knows that the
amount in dollars of her yearly bonus is represented by the expression - 1.25x + 651, where x is the
number of complaints customers had about her during the year. To find her bonus if she gets 12
complaints, she substitutes 12 for x. What should be her next step? What would her bonus be?
Answer:
multiply -1.25 x 12
Sense a negative and a positive will always be negative when dealing with multiplication you'll get -15
now -15 +651= 636
