Step-by-step explanation:
the perimeter of a rectangle is
2×length + 2×width =
2×(x + 10y) + 2×(7x² - x + 9y) =
2x + 20y + 14x² - 2x + 18y =
14x² + 38y

can you translate to English please ?:)
Answer:
-5
Step-by-step explanation:
y intercept occurs when x = 0
f(0) = -4(0)² + 2(0) - 5
f(0) = - 5
Answer:
C
Step-by-step explanation:
m∠7=m∠3
3x-10=2x+5
x=15
m∠3=2(15)+5
=35
m∠1=m∠3 (vert. opp. ∠)
= 35
Answer:
Translated 5 units right
g(x) = 2x - 4
Step-by-step explanation:
The original equation had a y-int of 6, but g(x) has a y-int of -4. Moving the line 5 units to the right will move the y-int down 10 units due to the positive slope of 2, so the translation is 5 units right.
The line shown still has a slope of 2 and a y-intercept of -4, so using the equation y = mx + b, g(x) = 2x - 4.
