write the equation 10x+5y=5 in the slope intercept form. Then graph the line
The equation 10x+5y=5 can be rewritten in slope-intercept form as y = -2x + 1. This equation's slope is -2 and the y-intercept is 1. The line intercepts the y-axis at (0,1) and for every 1 unit increase in x, y decreases by 2 units.
Explanation:To write the equation 10x+5y=5 in slope-intercept form, you need to solve for y. The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.
First, divide the entire equation by 5 to simplify it:
(10x+5y)/5 = 5/5 becomes 2x + y = 1.
Then, solve the equation for y:
y = -2x + 1
The slope (m) of the equation is -2 and the y-intercept (b) is 1. Therefore, the line intercepts the y-axis at the point (0,1) and for every 1 unit increase in x, y decreases by 2 units due to the negative slope.
To graph this line, first plot the y-intercept at the point (0,1). Next, from this point, move right 1 unit (increase in x) and down 2 units (decrease in y) to get the point (1,-1). Draw a straight line through these points to represent the equation y = -2x + 1.

use multiples to write two fractions equivalent to 7/9
Answer:
[tex]\displaystyle\frac{35}{45}, \frac{49}{63}[/tex] are two equivalent fractions of the given fraction.
Step-by-step explanation:
We are given the following information in the question:
We are given the fraction:
[tex]\displaystyle\frac{7}{9}[/tex]
We have to find an equivalent fraction. This could be done by multiplying both the numerator and the denominator by the same number.
Equivalent fraction:
Multiplying both numerator and denominator by 5
[tex]\displaystyle\frac{7\times 5}{9\times 5} = \frac{35}{45}[/tex]
Multiplying both numerator and denominator by 7
[tex]\displaystyle\frac{7\times 7}{9\times 7} = \frac{49}{63}[/tex]
Hence, [tex]\displaystyle\frac{35}{45}, \frac{49}{63}[/tex] are two equivalent fractions of the given fraction.
What is (are) the x-intercepts of the function graphed above?
Answer:
The x intercepts are -4, -1 and 5 or (-4,0), (-1,0) and (5,0).
Step-by-step explanation:
Consider the provided graph.
Here we need to find the x intercepts of the function.
The x-intercepts are where the graph crosses the x-axis.
Here, the provided graph crosses the x axis 3 times.
Thus there must be 3 x intercepts of the function.
Now label the points on which graph intersect the x axis as shown in figure 1.
Thus the labeled points are (-4,0), (-1,0) and (5,0)
Hence, the x intercepts are (-4,0), (-1,0) and (5,0) or -4, -1 and 5.

The Tigers lost 15% of the 60 games that they played this season. How many games did they win?
A 2.2 GB game is being downloaded on your laptop. When you have downloaded half a gigabyte, you notice that your computer has been downloading at the rate of .01GB per minute. (A) Write an inequality that represents at least how many minutes it will take to download the game (b) Your computed only has two hours of battery life, will it be enough to download the game?
The game which is 2.2 GB will need 170 minutes to download at a rate of 0.01 GB per minute. But the computer has only 120 minutes of battery life which is insufficient.
Explanation:The total size of the game is 2.2 GB. The part that is already downloaded is 0.5 GB, so the remaining size of the game to be downloaded is 2.2 GB - 0.5 GB = 1.7 GB. Now, since the downloading speed is 0.01 GB/minute, we extrapolate the remaining time as (1.7 GB) / (0.01 GB/min) which equals 170 minutes.
(a) So, the inequality representing at least how many minutes it will take to download the rest of the game is x ≥ 170, where x is the required time in minutes.
(b) Two hours of battery life is equivalent to 2*60 = 120 minutes. Since 170 minutes is required to download the game and the available battery life is only 120 minutes, the battery will not be enough to download the game.

Another flower is then chosen at random and given to a different woman for her to keep. Both women received a pink rose. Are these events independent or dependent?
A) Dependent because the women both received a pink rose.
B) Independent because the women both received a pink rose.
C) Dependent because when the first flower is taken, it affects the ratio of the types of flowers in the vase.
D) Independent because when the first flower is taken, it does not change the ratio of the types of flowers in the vase.
Answer:
Option C - Dependent because when the first flower is taken, it affects the ratio of the types of flowers in the vase.
Step-by-step explanation:
Given : A flower vase has 5 white lilies, 4 pink roses, and 6 yellow carnations.
One flower is chosen at random and given to a woman for her to keep.
Another flower is then chosen at random and given to a different woman for her to keep. Both women received a pink rose.
To find : Are these events independent or dependent?
Solution :
According to the statements,
The probability that the second woman receives a pink rose is dependent upon what the first woman receives.
Total flowers = 5+4+6=15
If the first woman does not receive a pink rose,
Then, the probability of the second woman receiving one is [tex]\frac{4}{15}[/tex]
If the first woman does receive a pink rose
Then, the probability of the second woman receiving one is [tex]\frac{3}{15}=\frac{1}{5}[/tex]
Therefore, Option C is correct.
Dependent because when the first flower is taken, it affects the ratio of the types of flowers in the vase.
