Answer:
x = 5
Step-by-step explanation:
As it is an isosceles triangle so two sides BA and BC are equal. So,
BA = BC
3x + 3 = 2x + 8
3x - 2x = 8 - 3
x = 5
Therefore AC = 5

Answer:
(x+4)(x-3) or A
Step-by-step explanation:
I'm going to assume that you meant to write x² and not x2
which means we have
x²+x-12
and we need to factor this
to do this we need two numbers that add up to 1 (b) but mulitply to -12 (a*c)
our two numbers are
4, -3
Which means the answer is
(x+4)(x-3)

Opt A.) is the answerFireworks are set off from a hill 80 feet above the Mississippi. The outer
shells will fall after exploding at its maximum height. The firework's height
about the surface of the river is given by the function h(t) = -16t^2 + 64t +
80. What is the height of the rocket after 1.5 seconds?
Answers
Answer:
752 ft
Step-by-step explanation:
Assuming t represents time, and the time we are trying to find is how high the rockets go after 1.5 seconds, we must take the equation and put 1.5 in wherever t occurs, this looks like:
-16(1.5)²+64(1.5)+80
solving this, we get:
-24²+96+80
576+96+80

Find the values of x and y.
help please work has to be shown ..
Answers
Answer:
x = 7 and y = 17
Step-by-step explanation:
16x + 9x + 5 = 180 cuz they are supplementary
25x = 175
x = 7
We also know that 16x + 4y = 180
so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17
hope this makes sense

Answer:

Step-by-step explanation:
The pythagorean theorem states that a^2+b^2=c^2. a and b are the shorter sides and c is the hypotenuse, or the longest side. You can tell the hypotenuse because it is opposite to the right angle.
Therefore, a=6, b=8 and c=x. You can switch a and b if you like, it doesn't really matter.
using the pythagorean thm. 6^2+8^2=x^2. You simplify the exponents and combine like terms to get x^2=100. You take the square root of both sides and get 10.

You now have a lot of experience working with equations that compare two quantities. For example, while working with the height of a tree, you found the
relationship y = 41+5. which compared 2 (the number of years after it was planted) with y (its height in feet). Use the equation for this tree to answer the
questions below

Answers
Answer:
If you mean y = 4x + 5, then the answer is 5 (the height would be 5 feet)

Find the slope of the line shown on the graph to the right (-4,-3) and (2,3)
Answers
Answer:
y=x+1
Step-by-step explanation:
to do this we have to use the slope formula, Rise/Run which is (y2-y1)/(x2-x1) so (3-(-3) or 3+3 divided by (2-(-4) or 2+4, so the slope would be 6/6 or 1. so it is up one over one, and since at the x coordinate of 0 it is y=1 we know the formula must be y=x+1
Answer:
m = 1
Step-by-step explanation:
Use the equation [tex]m=\frac{y2-y1}{x2-x1}[/tex] to find the slope.
next, the equation should look like: [tex]y=\frac{3+3}{2+4}[/tex]
Next you should get the equation: [tex]m = \frac{6}{6}[/tex]
Finally, just divide 6/6 and the answer will be m = 1
