The equation for Pythagorean theorem is
a^2 + b^2 = c^2
c = the hypotenuse of a right angle, the longest sides
a, and b is the shorter sides of the right angle
Since we have the hypotenuse, and one number for the other side, cut the other side (6) in half because of how a area of a triangle is based off the equation, h x b divided by 2 = A
Plug it into the equation above:
3^2 + b^2 = 8^2
9 + b^2 = 64
b^2 = 55
b = √55
D. x = √55 is your answer
Hey there! :)
y = 3/4x - 2
To find the slope and y-intercept, simply use slope-intercept form to understand this.
Slope-intercept form is : y = mx + b ; where m = slope, b = y-intercept.
Therefore, you must ask yourself : which value is in the "m" spot and which value is in the "b" spot in our given equation?
Using this logic, we can come to the conclusion that :
Slope = 3/4 & Y-intercept = -2
~Hope I helped! :)
Work is shown (^_^)
Did #9-10 also
3) 3p -2 = -29 Isolate 3
3p= -29+2
3p= -27 Divide by 3
p = -9
4) 1- r = -5 Isolate r
-r= -5-1
-r= -6 Multiply by -1
r= 6
5) k-10/2 = -7 Multiply by 2
k-10= 2(-7)
k-10= -14
k=-14+10
k=-4

In order to rewrite an expression in radical form using exponents, we must consider the power of the root (is the radical the typical square root, cubed root, etc) and the value of any exponents contained in the radical.
Using this information, we will make the power of the radical the denominator of our exponent, and whatever exponent is contained in the radical will become the numerator.
Example:
√(x³) = square root of x³ = x^(3/2)
I remember doing this question. The question went like:
<span>1.25x + 1.49 = 100
What error did Barbara make in writing the equation?
And the answer would be that Barbaras equation did not consider the number of ice tea drinks. Hence, </span>She put the correct price in the equation but she didn't put the (x) number of iced tea drinks. In other words,This is because she has added 1.25 X the number of water bottles sold to 1.49, the cost of one iced tea.
So, the correct equation would be:
1.25x +1.49y = 100
Would really appreciate if you would put me as Brainliest answer.
