Answer:
x= -1
y=5
Step-by-step explanation:
5x +2( 3x +8) =5
5x + 6x + 16= 5
11x +16 =5
11x= -11
x=-1
y= 3(-1) +8
y= -3+ 8
y=5
check
5 = 3(-1) + 8
5=5
5(-1) + 2(5) = 5
-5 +10 =5
5=5

what is the value of x in simplest radical form?
Answer:
25
Step-by-step explanation:
For these types of problems you'll need the Pythagorean theorem (woohoo..). This amazing formula looks like: a^2 + b^2 = c^2. The a and b in this formula are the legs of the triangle, the straight non-diagonal lines. The c stands for the hypotenuse which is the diagonal line.
Since you have both of the legs we can go ahead and plug that into our equation: 15^2 + 20^2 = c^2.
NOTE: It doesn't matter which leg you plug into which variable! Just make sure it's not c!
With exponents, it just means to multiply the number by itself. 15^2 is the same as 15(15). So, simplifying the equation, we get: 225 + 400 = c^2.
This part is pretty straightforward. I mean, unless you don't remember addition... Adding it together, you will get 625 = c^2.
This part kinda requires a calculator if you don't know all of your square roots. Luckily, this is a perfect root and goes into 25.
And that, my friend, is your answer. Hope this helped :)

work out the circumference of a cirlce with a diameter of 1.8m
Answer:
5.56 m
Step-by-step explanation:
Circumference = 2πr
r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:
1.8 ÷ 2 = 0.9
Circumference = 2 × π × 0.9
= 5.56 m ( in 3 significant figures )
write an equation of the line that passes through the point (0,3) and whose slope is 2
Answer:
y - 2x = 3
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:
y - 3 = 2(x - 0), or
y - 3 = 2x, or
y - 2x = 3
Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b: it is 3.

Step-by-step explanation:
A researcher takes a random sample of 2,496 drivers and finds that 1,603 put their phone in "drive mode” to not be distracted while driving. A 90% confidence interval for the proportion of drivers who use "drive mode” on their phones is (0.626, 0.658). Which statement correctly interprets the interval? The researcher can be 90% confident that 64% of all drivers will use “drive mode” while driving. There is a 90% probability that the proportion of drivers who use “drive mode” lies between 0.626 and 0.658. The researcher can be 90% confident that the interval from 0.626 to 0.658 captures the true proportion of all drivers who use “drive mode.” If this procedure is repeated many, many times, the true proportion of drivers who use “drive mode” will be captured 90% of the time.
Answer:
The researcher can be 90% confident that the interval from 0.626 to 0.658 captures the true proportion of all drivers who use “drive mode.”

90
x
2x
90 = x + 2x
90 = 3x
90 / 3 = 20
3x / 3 = x

Intercepts: independent practice Write the ordered pair describing the coordinates of each intercept. 1. X-intercept: -6 2. Y-intercept: -2.3 3. Y-intercept: 3/4
Answer:
[tex](-6, 0)[/tex]
[tex](0, -2.3)[/tex]
[tex](0,\frac{3}{4})[/tex]
Step-by-step explanation:
Solving (1). x-intercept: -6
At x intercept, [tex]y= 0[/tex]
So, the ordered pair is: [tex](-6, 0)[/tex]
Solving (2): y-intercept: -2.3
At y intercept, [tex]x = 0[/tex]
So, the ordered pair is: [tex](0, -2.3)[/tex]
Solving (3): y-intercept: 3/4
At y intercept, [tex]x = 0[/tex]
So, the ordered pair is: [tex](0,\frac{3}{4})[/tex]
