Answer:
x=3 and y=2
Step-by-step explanation:
1.) 4x+3(5x-13)=18
expand into 4x+15x-39=18
18+39= 57
15x+4x= 19x
57/19= 3 so x=3
substitute 3 into y= 5x - 13
and you get 2 so y=2
Step-by-step explanation:
The formula for the slope is <em>y=mx+b</em>, where <em>m</em> is the slope and <em>b</em> is the y-intercept. Since 2 is being multiplied by <em>x</em>, that means it is the slope. The variable <em>y</em> is being added, so it has to be the y-intercept.
Answer:
2=slope & y-intercept=y
Hello there, and thank you for posting your question here on brainly.
Since we know what both of the exponents are, we can rewrite the equation for it.
3 * 2 - (-4)
We can evaluate from here.
I can see we have a positive number subtracting a negative number.
Use the rule where x - (-y) = x + y
2 * 3 + 4
Now we can get solving.
2 * 3 ==> 6
6 + 4 ==> 10
10 is the final answer.
Hope this helps! ☺♥
