Answer:
The y-intercept is answer b. (0, -3)
Step-by-step explanation:
To find the y-intercept, fill in x with 0.
4x + 5y = -15
4(0) + 5y = -15
0 + 5y = -15
5y = -15
y = -3
So, the y-intercept would be (0, -3).
Answer:
The number is 79
Step-by-step explanation:
Let the number be 'x'
x + 17 = 96
Subtract 17 from both sides,
x + 17 -17 = 96 - 17
<h3> x = 79</h3>
Answer:
1/2 and 9/14
Step-by-step explanation:
Let the first fraction be 1/2
Let the second fraction be x
1/2 + x= 8/7
x= 8/7-1/3
= 16-7/14
= 9/14
Hence the two numbers are 1/2 and 9/14
What is that supposed to be 70, 7 or 700
U S E A N E Q U A T I O N
45=x+(x+17)
45=2x+17
28=2x
/2 /2
14=x
x 14 is the first number
x+17 31 is the second number
