a) equation to model this situation can be
14x + 68 = 0
b) so, the money he had before two weeks are
14(3) + 68 = $120
c) equation to determine when Marty will run out of money if he continues to spend at this rate is 57 days and 8 hours.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Given:
Spent per day = $3
After 14 days = $68 left
a) equation to model this situation can be
14x + 68 = 0
b) so, the money he had before two weeks are
14(3) + 68 = $120
c) equation to determine when Marty will run out of money if he continues to spend at this rate.
let the total money be a
a - 14x = 120
a = 14(3) + 120
a = 172
So, if m is the number of days
172 - 3m = 0
3m= 172
m = 57 days and 8 hours

A photo of a painting measures
13 inches by 17 inches. The scale factor
is 1
3 . What size is the painting?
The size of the painting is [tex]\( \frac{13}{3} \) inches by \( \frac{17}{3} \)[/tex] inches.
If the photo of the painting has dimensions of 13 inches by 17 inches and the scale factor is 1/3 it means that the dimensions of the painting itself are 1/3 times the dimensions of the photo.
To find the size of the painting, we need to multiply the dimensions of the photo by the scale factor.
For the length:
[tex]\[ \text{Length of painting} = 13 \times \frac{1}{3} = \frac{13}{3} \][/tex]
For the width:
[tex]\[ \text{Width of painting} = 17 \times \frac{1}{3} = \frac{17}{3} \][/tex]

Write an equation in slope-intercept form of the line that passes through (-1,-3) and is parallel to the graph of y=4.
Answer:
The line parallel to this one and through the given point would be y = -3.
Step-by-step explanation:
In order to find a parallel line, we first have to accept that this is a horizontal line. This is because there is no x value in the equation. That means in order to make it horizontal as well, we need it to have no x value again.
Given the ordered pair, this means our new equation is y = -3

Answer:
Step-by-step explanation:
Distance between two points a and b using the absolute value is given by
|b-a|.
Here we have a=-13
and b =17
so
Distance = | 17- (-13) |
Distance = |17 +13 |
Distance = | 30 |
Distance = 30 units
In absolute value, the distance is written as |30|
The given points:
[tex](x_1, x_2) = (-13, 17)[/tex]
To find:
the distance between -13 and 17The distance between the two points on a number line is calculated as;
[tex]Distance = \sqrt{(x_2-x_1)^2} \\\\Distance = \sqrt{(17--13)^2}\\\\Distance = \sqrt{(30)^2} \\\\Distance = + /- \ \ 30[/tex]
In absolute value, the distance is written as;
Distance = |30|

Step-by-step explanation:
Inmagine functions as little machines that turn one number into another, the domain would the numbers that we can enter to the machine so we would have a real number on the output of it.
In this specific case we can use all the numbers but 4 because if we make [tex]x=4[/tex] we would have [tex]\frac{12}{4-4}=\frac{12}{0}[/tex] and this is an indeterminate form which won't be solution to the problem.

Answer:
Step-by-stPart A
Answer: 7/36
This is in fraction form
The decimal version of this number is roughly 0.1944
-----------------------------------
To get this answer, we multiply the fractions 7/9 and 2/8
The fraction 7/9 is the probability of selecting purple on the first draw. There are 7 purple out of 9 total (2+7 = 9)
The fraction 2/8 is the probability of selecting white on the second draw. This is assuming we don't put the first selection back in the bag. There are 2 white out of 8 marbles over
Multiply the fractions to get:
(7/9)*(2/8) = (7/9)*(1/4) = (7*1)/(9*4) = 7/36
============================================================
Part B
Answer in fraction form: 1/36
Answer in decimal form: 0.0278 (which is approximate)
------------------
We have 2 white out of 9 total. So the probability of getting white the first time is 2/9
After we select and don't put that first selection back, we have 1 white out of 8 left over. The probability of getting white a second time is 1/8
Multiply the fractions:
(2/9)*(1/8) = (2*1)/(9*8) = 2/72 = 1/36
============================================================
Part C
Answer: There is a greater chance to get two purple in a row
Without doing any math, you can tell that purple is more likely simply because there are more purple than white. We have 7 purple and 2 white. For any given single selection, we have a greater chance of picking purple over white.
If you want do to the math, then the probability of selecting two white marbles in a row is 1/36 = 0.0278 which was found in part B above.
The probability of selecting two purple is (7/9)*(6/8) = (7/9)*(3/4) = (7*3)/(9*4) = 21/36 = 7/12 = 0.5833
In summary,
the probability of selecting two white marbles in a row is 0.0278
the probability of selecting two purple marbles in a row is 0.5833
we see that the probability for the two purple marbles is much greater
5 − (x + 5) > −2(x + 4)
The equation of a circle is (x+7)to the second power+(y−13)to the second power=196 .
What is the center of the circle?
Enter your answer in the boxes.
Answer:
(-7,13)
Step-by-step explanation:
The equation of a circle is (x+7)to the second power+(y−13)to the second power=196
(x+7)^2 +(y-13)^2 = 196
To find the center of the circle we use the center radius form of the circle
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
where (h,k) is the verted and r is the radius of the circle
now we compare with the given equation
h= -7 and k =13
So center of the circle is (-7,13)
