Answer:
d < 7/9
Step-by-step explanation:
Add 7d +10
7 > 9d
Divide by 9
7/9 > d
Answer:
x = 2/3 or x = -2/3
Step-by-step explanation:
Solve for x over the real numbers:
9 x^2 = 4
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 9:
x^2 = 4/9
Hint: | Eliminate the exponent on the left-hand side.
Take the square root of both sides:
Answer:x = 2/3 or x = -2/3
Hi there!
Something really good to remember about trigonometry is SOHCAHTOA. I won’t dive into too much detail about it, but you should google it for future assignments.
Anyways,
tan50°=14/AB
ABtan50°=14
AB=14/tan50°
AB=11.75
cos50°=14/AC
ACcos50°=14
AC=14/cos50°
AC=21.78
For the measure of angle C you can use a theorem called the third angle theorem. In every single possible triangle, the sum of all three angles adds up to 180°. You can set up an equation like so...
angleC=180-(90+50)
angleC=180-140
angleC=40°
Answer:
Correct options are F and D.
Step-by-step explanation:
First, the slope. 5-(-5)/-4-1
This can be simplified to 10/-5, or -2.
Y intercept: (0, -3).
Slope intercept form: y=-2x-3
Point slope: y-5=-2(x+4) or y+5=-2(x-1)
