6 0
1.) 3 + 2 x 10 = 3 + 20 = 23
2.) 2(1-4)^2 = 2(-3^2) = 2(9) = 18
3.) -3^2 + 3^2 = 9 + 9 = 18
4.) 8 - [(4-7) + (8-1)] = 8 - [-3 + 7] = 8 - 4 = 4
5.) 4 - {8 - (2-4)} = 4 - {8 - (-2)} = 4 - {8 + 2} = 4 - 10 = -6

what’s the slope and y intercept of the loire that is perpendicular to y=-2x-5 and passes through the point (-3,-6)
Doss [256]

Answer:

slope: ½

y-intercept: -4½

Step-by-step explanation:

Slope: negative reciprocal of -2

-1/-2 = 1/2

y = ½x + c

-6 = ½(-3) + c

-6 = -3/2 + c

c = -6 + 3/2

c = -9/2 = -4½

Which equations can be used to solve for acceleration? Select four options.
sweet [91]

Equations for the acceleration: a=\frac{v-u}{t}, v=u+at

Step-by-step explanation:

The acceleration of a body is the rate of change in velocity of the body; it is given by

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time taken  for the velocity to change from u to v

The equation can be also written as

v=u+at

Therefore, these two equations can be used to find the acceleration.
