Answer:
x=−414
Step-by-step explanation:
Let's solve your equation step-by-step.
x
−18
=23
Step 1: Multiply both sides by -18.
x
−18
=23
(
x
−18
)*(−18)=(23)*(−18)
x=−414
Answer:
which
Step-by-step explanation:
which one is answer
<span>y=-2/4x +2
slope = -2/4 = -1/4
</span><span>parallel so it has same slope = -1/2
passing thru (6,3)
y = mx+b
3 = -1/2(6) + b
b = 3 +3
b = 6
equation
y = -1/2x + 6</span>
Answer:
84°
Step-by-step explanation:
1. <u>point of intersection of 2y=x-13 and 3y+x+12=0</u>
x = 2y + 13 ==> 3y + (2y+13) + 12 = 0 ==> 5y + 25 = 0 ==> y = -5
x = 2*(-5) +13 = 3
point of intersection: (3 , -5) L1: pass (3 , -5) and (-4 , -7)
slope of L1 = (-7 - -5)/(-4-3) = -2 / -7 = 2/7
L2 pass (3 , -5) perpendicular to 2x-5y=4
2x-5y=4 ==> y = 2/5 x - 4 slope = 2/5
so slope of L2 = -5/2
angle Θ between two slopes: tan Θ = | (m2-m1) / (1 + m1*m2)|
==> = | (-5/2 - 2/7) / (1 + -5/2*2/7) | = |(-39/14) / (4/14) | = |- 39/4| = 39/4 = 9.75
Θ = 84°
Take the total amount of babies 720,000 and divide by 3. You will get 240,000 babies. (This is also 1/3 of 720,000
