Answer:
y = 5x + 4
Step-by-step explanation:
Starting with 5x - y = -4
Subtract 5x from both sides to get -y = -5x - 4
Multiply the entire equation by -1 to make the y positive
You get y = 5x + 4
Step-by-step explanation:
The answer is B and C
If you need any explanation in it or anything on math you can communicate with me on Whats on this number +201557831028 or in email or face or anything
a ratio is how many X there are per Y. for example, a fraction is a ratio: 10/5 = 2 because there are 2 fives in a ten. but usually a ratio is written as x:y.
so to find these ratios, first we need to find the number of girls. 30 students-16 boys = 14 girls.
the ratio of girls to boys is 14:16 because there are 14 girls to every 16 boys. we simplify this to 7:8.
the ratio of girls to all students is 14:30. we simplify this to 7:15.
the ratio of boys to girls is 16:14, which simplifies to 8:7.
the ratio of boys to all students is 16:30, which simplifies to 8:15.
Answer:
The standard form of the line is -7x + 11y = -33
Step-by-step explanation:
For this one, we can first put the equation in slope-intercept form (since we have slope and intercept).
y = mx + b
y = 7/11x - 3
Now that we have this, we can manipulate the equation to put it in standard form.
y = 7/11x - 3 ----> subtract 7/11x to both sides
-7/11x + y = -3 ----> multiply both sides by 11
-7x + 11y = -33
