Find the slope and y-intercept of the equation 4x+5y=-9

Mathematics
1 answer:
Vesnalui [34]3 years ago
6 0

Yo sup??

4x+5y=-9

y=(-4x)/5-9/5

we see that this is of the form y=mx+c

where m is the slope

therefore the slope of the line is -4/5

To find y intercept, put x=0

y=-4*0/5-9/5

y=-9/5

Therefore y intercept is -9/5

Hope this helps.

PLZ HURRY IT'S URGENT!!
Y_Kistochka [10]

Answer:

n + 6 = 7n

Step-by-step explanation:

"The sum of a number and six" would mean the number plus 6: n+6 and "is seven times the number" indicates that it would be equal to the product of 7 for n: 7n. According to this, the answer is that the translation of the sentence into an equation is: n+6=7n.

n − 6 = 7n is not right because the statement says the sum of a number and six.

7(n + 6) = n is not right because the statement indicates that seven multiplies n on the right side as it says seven times the number.

n = 7n + 6 is not right because the statement says the sum of a number and six which would be on the left side and that this would be equal to seven for n.

Tju [1.3M]

The time take for the cyclist to travel from Fort Worth to Fresno is 90 \ hours

Explanation:

It is given that the distance from Fort Worth to Fresno is 1,530 miles.

The average speed of the cyclist is 17 miles per hour.

The time travelled by the cyclist can be determined using the formula,

Distance=Speed \times Time

Substituting the value of distance and speed, we get,

1530=17\times Time

Dividing both sides by 17, we get,

90 =Time

Thus, the time take for the cyclist to travel from Fort Worth to Fresno is 90 \ hours
