Answer:
The answer is 500
Step-by-step explanation:
500/10=50
We can set up a proportion here. On map scales, the scale goes like:
“1 (length on the map) : x (real life length)”
Here, we have 2 : 8. We need to make it so the first number is 1, because thats easier for measuring.
2 : 8 /divide both sides by 2
1 : 4
The scale would be 1in : 4mi (in other words, 1 inch on the map corresponds to 4 miles in real life).
The slope-point form: y - y₁ = m(x - x₁).
The slope-intercept form: y = mx + b.
We have:
and the point (-5, 7)
therefore
Answer:
C. x + x² - 5. quadratic trinomial
Step-by-step explanation:
The expression -5+ x² + x is already simplified so we only need to rearrange the terms.
The standard form for a quadratic equation is ax² + bx +c. We knowits quadratic because of "x²".
-5+ x² + x => x² + x - 5
The degree is 2 because the degree of an equation is the greatest exponent on the variable(s) in one of the terms.
Between x², x and -5, x² has the greatest exponent of 2.
