=44/1
=44
Answer:
Step-by-step explanation:
3-(2x-5)=-4(x+2)
We simplify the equation to the form, which is simple to understand
3-(2x-5)=-4(x+2)
Remove unnecessary parentheses
3-2x+5=-4*(x+2)
Reorder the terms in parentheses
3-2x+5=+(-4x-8)
Remove unnecessary parentheses
+3-2x+5=-4x-8
We move all terms containing x to the left and all other terms to the right.
-2x+4x=-8-3-5
We simplify left and right side of the equation.
+2x=-16
We divide both sides of the equation by 2 to get x.
x=-8
Answer:
s(5) = -12
Step-by-step explanation:
s(t) = - t³ + 7t² - 14t +8
Find the displacement during the first 5 seconds.
When t = 5
s(t) = - t³ + 7t² - 14t +8
s(5) = -5³ + 7(5)² - 14(5) + 8
= -125 + 7(25) - 70 + 8
= -125 + 175 - 70 + 8
= -12
s(5) = -12
Meet of lines: y = 3x − 2 and y = -2x + 3?
y=3x-2 has slope 3 and y intercept -2 (which means thru (0,-2)) , so that's the blue line through point D.
y=-3x+3 has slope -2 and y intercept 3, so the red line through points A, C and D.
The point D(1,1) is the intersection of the lines. Let's check that algebraically:
3x-2=3(1)-2=1=y, good
-2x+3 = -2(1)+3=1=y, good
Answer: D
Answer: 25 units squared
Step-by-step explanation:
Draw a line down from p and go right connecting to r. The units there are equal to the ones on the triangle you were given. 5 horizontally and 10 vertically. 5 times 10 is 50 divided by 2
