Answer: a=1

Step-by-step explanation:

-8(a-4)+3a=2(4a+9)+1 given

-8a+32+3a=8a+18+1 distribute

+8a +8a

32+3a=16a+18+1 subtraction property of equality

-3a -3a

32=13a+18+1 addition property of equality

32=13a+19 add like terms

-19 -19

13=13a addition property of equality

÷13 ÷13

1=a multiplication property of equality

a=1 is the answer. Hope this helps!

Answer:

Step-by-step explanation:

y - y₁ = m ( x - x₁)

y - 5 = - 3 (x - 12)

It’s confusing, would the answer be square root 7 over 4?

Colt1911 [192]

Answer:

$\tan U = 1$

Step-by-step explanation:

$\text{Apply Pythagorean theorem,}\\\\~~~~~~\text{Hypotenuse}^2 = \text{Base}^2 + \text{Perpendicular}^2\\\\\implies UT^2 = UV^2 +VT^2\\\\\implies UV^2 = UT^2 -VT^2\\\\\implies UV^2 = \left(7\sqrt 2 \right)^2 - 7^2\\\\\implies UV^2 = 49(2)-49\\\\\implies UV^2 = 49\\\\\implies UV = \sqrt{49} \\\\ \implies UV = 7$

$\text{Now,}\\\\~~~~~~~~\tan \theta = \dfrac{\text{Perpendicular}}{\text{Base}}\\\\\\\implies \tan U = \dfrac{7}{7}\\\\\\\implies \tan U = 1$
