Can someone please find out what x is?
Answer: x = 2
Simplify and Distribute
(−5)(4x)+(−5)(−2)=(−2)(3)+(−2)(6x)
−20x+10=−6+−12x
−20x+10=−12x−6
Adding 12x both sides.
−20x+10+12x=−12x−6+12x
−8x+10=−6
Subtract 10 both sides
−8x+10−10=−6−10
-8x = -16
Then divide both sides by 8
-8x/8 = -16/8
x=2
4. Estimate.
12 x 11
36 x 29
84 x 27
Step-by-step explanation:
12*11=132
36*29=1044
84*27=2268

find the length of side BD round your answer to the nearest hundred
Answer:
The length of side BD is 4.62 units to the nearest hundredth
Step-by-step explanation:
In Δ ABC
∵ m∠ABC = 90°
∵ BD ⊥ AC
∴ AB × BC = BD × AC
∵ AB = 12 units
∵ BC = 5 units
∵ AC = 13 units
→ Substitute them in the equation above
∴ 12 × 5 = BD × 13
∴ 60 = 13 BD
→ Divide both sides by 13 to find BD
∴ 4.615384615 = BD
→ Round it to the nearest hundredth
∴ BD = 4.62 units
∴ The length of side BD is 4.62 units to the nearest hundredth

How do I do this? And what’s the answer??
Answer:
its asking you what the slope of the line is (rise/run) and for the point at which the line crosses the y axis (verticle line)
Step-by-step explanation:
When finding the slope you count the number of units up and the number of units across. This would be -1/1 or -1 because the graph shows a scale of 100, and the slope is going down 100, and across 100. this makes the slope negative since it's going downwards. so the slope would be -100/100 which would simplify to -1.
the y-intercept is where the line crosses the y axis. if this point is below the x-axis, then the y-intercept would be negative. in this problem however, the line crosses the y-axis at the origin (0,0)
so your equation would be y=1x+0, but simplified it would be y=x (the one isnt used because there is a single x value and the +0 is gone because it holds no value)

Bart wants to rent a car. The fee is $25 plus $0.55 per mile. He has budgeted $212 for the car. Write an
inequality to show how much he can spend for the car.
Answer:
25 + 0.55x ≤ 212
Step-by-step explanation:
Bart can only spend 212, hence the less than or equal to symbol. The cost of using the car must be at most 212, so 25 and 0.55x are on the same side. 0.55x represents the cost of driving an unknown amount of miles.
Write the equation of the line that is parallel to the line y= 3x+ 6 and passes through the point (4, 7).
Answer:
Is this slope?
Step-by-step explanation:
Answer:
y = 3x - 5
Step-by-step explanation:
Let the equation be y = mx + c
Since the equation is parallel to y = 3x + 6, gradients of the two eqns are the same
therefore, m = 3
sub (4, 7):
7 = 3(4) + c
c = -5
therefore, equation of the line is y = 3x - 5
How can you find the slope from a table?
Answer:
you find slope from a table by taking any two points. the left side is the input of the table, the x, and the right side is the output the y. whenever you're finding the points to do slope, they must be correlated.
__x__|__y__
___2_|__4___
__3__|___6__
so if you want to choose 2 for the x input then you must choose the 4 as the y output.
After choosing the two points, (2,4) and (3,6), you need to find the slope which is y-y/x-x. so in this case it's 6-4/3-2. after subtracting you get, 2/1 which if you simplify, it's 2. Or you divide which is also 2. I hope this helped.

Calculate the variance of the following set of data.

Variance is the measurement of the spread between numbers in a given set of data.
The variance for the set is 12083.929
What is a variance?It is the measurement of the spread between numbers in a given set of data.
We have,
3, 33, 303, 233, 3, 73, 83, 63
The formula to find variance:
Find the means of the set of data.
Find the deviation of the set of data from the mean.
Find the sum of the squares of the mean deviations.
Divide the sum of the squares of the mean deviations by (n-1)
where n is the number of data in the set.
The mean:
= (3 + 33 + 303 + 233 + 3 + 73 + 83 + 63) / 8
= 794/8
= 99.25
Deviation from the mean:
3 - 99.25 = -96.25
33 - 99.25 = -66.25
303 - 99.25 = 203.75
3 - 99.24 = -96.25
73 - 99.25 = -26.25
83 - 99.25 = -16.25
63 - 99.25 = -36.25
The sum of the squares of Mean deviation:
= 9264 + 4389 + 41514 + 9264 + 689 + 264 + 1314
= 84587.5
The variance:
= 84587.5 ÷ (8 - 1)
= 84587.5 / 7
= 12083.929
Thus,
The variance for the set is 12083.929
