Answer:
For the line represented by y = 5 x − 7, the slope is 5 and the
y-intercept is -7.
Step-by-step explanation:
The equation is in <em>Slope-intercept form</em>.
The letter 'm' represents the slope.
The letter 'b' represents the y-intercept.
In the equation 
:
- 5 is the slope because it replaces 'm' in the equation. The 'm' is the slope.
- -7 is the y-intercept because it replaces 'b' in equation. The 'b' represents the y-intercept.

8x+1500 is the needed expression.
Step-by-step explanation:
The root of an equation is when x=0.
We need to rewrite this as 3x²-4x+10=0.
The quadratic formula is
(-b+or-sqrt(b²-4ac))/2a
so 4+or-sqrt(16-120)/2a
since the sqrt can no be negative this answer will have imaginary numbers.
(4+2i sqrt(26))6 and (4-2i sqrt(26))6
simplified is
x=(2+i sqrt(26))/3 and x=(2-i sqrt(26))/3
Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
Plug 1 in for x to get 7y=3(1)-7
7y=-4
y=-4/7
