What is 8 times larger than 3
8 x 3 = 24 for should be 24
Only because 8 times larger than three seems like a multiplication problem..
I hope this helps if it is correct!
Answer:
(8+1) x 3 = 27
Step-by-step explanation:
this is correct rather than 8 x 3 = 24 because both sides of 8x3=24 are equal rather than the sum being greater than the statement.
Which of the following statements describe how to find the measure of EC?
Answer:
c
Step-by-step explanation:
by Pythagorean theorem
The correct statement to find the measure of EC is: Create a proportion with the legs of the triangles where segment BC is the same measure as segment AB. Add the length of segments BC and BE to find the length of segment EC.
Since BE is parallel to AD, triangles ADC and BEC are similar by the Alternate Interior Angles Theorem. Therefore, the ratio of corresponding sides of these triangles is equal:
AD / BC = DC / EC
Since AD = 4√138 m and BC = AB = 6√3 m, we have:
4√138 / 6√3 = DC / EC
Simplifying:
2√3 / 3 = DC / EC
Now, we know DC = BE = √138 m. Let's substitute that value:
2√3 / 3 = √138 / EC
Now, solve for EC:
EC = (√138 * 3) / (2√3)
EC = 3/2 * √(138/3)
EC = 3/2 * √46
Thus, the measure of EC is 3/2 * √46 m. The correct statement provided earlier explains the process to find this value.

Given the functions: f (x) = 2x to the 2nd power and
s (x) = 2 (x-3) What is the value of f(2) + s(-1)?
Answer:
0
Step-by-step explanation:
f(x)=2x²
s(x)=2(x-3)
Plugging in the numbers, we get:
f(2)= 2 * (2)²
f(2)= 2*4
f(2)= 8
s(-1)= 2*(-1-3)
s(-1)= 2*(-4)
s(-1)= -8
f(2) + s(-1) = 8 - 8 = 0

Step-by-step explanation:
line j passes through the coordinate points (4,1) and (-3,_6).what is the y-intercept of the equation that is parallel; to line j and passes through the point,(7,1)
Answer: y-intercept is -6
Step-by-step explanation: Calculate the slope of the line between the two given points:
Rise/Run = slope, m in the standard form of a straight line: y=mx+b, with b the y-intercept (the value of y when x=0).
Rise = 1 - (-6) = 7
Run = 4 - (-3) = 7
Slope = Rise/Run, 7/7, or 1
y=mx+b
y = 1x+ b
Find b by entering one of the two given points. I'll pick (4,1).
y = 1x+ b
What's important now is the next step. The equation "that is parallel" must have the same slope as the reference equation, 1 in this case.
[If, out of curiosity, you want the full equation of the reference line, we can find b in this way:
Enter one of the two given points and solve for b. I'll pick (4,1):
y = 1x+ b
1 = 1*(4)+ b
b = -3
y = 1x - 3 is the first equation.]
All we really needed from the first, or reference, equation is the slope, 1 in this case. Parallel lines have the same slope, so we want an equation in the form:
y=1x+b
This equation will be parallel, regardless of the value of b. But we want it to go through a specific point, (7,1). So use that point and solve for b:
y=1x+b
1=1*7+b
b=-6
The equation is y=1x-6
20. At a track meet, teams get points for placing in the top 6 of each event. 1" place = 10 pts, 2nd place 8 pts, 30 = 6 pts, 4 = 4 pts, 5* = 2 pts, and 6h - 1 pt. At the last trackmeet, El Dorado scored 188 pts off of 38 scoring events. The number of 1 place finishes was equal to the number of 4 place finishes. The number of 2nd place finishes was half as many as the number of 3d place finishes. The number of 5 places finishes was equal to the sum of the number of 1" and 2nd place finishes. The number of 2nd place finishes was equal to the number of 6 place finishes. How many of each place did El Dorado have?

What is the equation in point slope form of the line that passes through the point ( 2 , -4 ) and has a slope of 4?
Answer:
y + 4 = 4(x - 2)
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
Where m = slope and (x1 , x2) = any given point.
We are given that the equation has a slope of 4 and passes through the point (2,-4)
So m = 4 and (x1,y2) = (2,-4)
We then plug in these values into the point slope form equation to get the answer.
y - y1 = m(x - x1)
m = 4 and (x1,y1) = (2,-4)
plug in values
y - (-4) = 4(x-2)
remove parenthesis on "-4" and change sign because the two negative signs cancel out and change into a positive sign
We end up with y + 4 = 4(x-2)

The number of girls in a school is three times the number of boys. Express it in ratio.
Step-by-step explanation:
Let,
The number of boys be = x

Therefore,
Ratio of number of girls to number of boys in school will be,
[tex] = \frac{number \: of \: girls \: in \: school}{number \: of \: boys \: in \: school} [/tex]
[Putting the number of boys and girls][tex] = \frac{3x}{x} [/tex]

x = (-3+√15)/2 or, x = (-3-√15)/2

2x²+6x-3=0
Standard quadratic formula,
ax²+bx+c = 0
where,
x =(-b±[tex]\sqrt{b^{2}-4ac }[/tex])/2a ...............................(i)

Find the value of x so that the function has the given value.
Answer:
x = 10
Step-by-step explanation:
Given h(x) = 2x - 14 and h(x) = 6, then equating
2x - 14 = 6 ( add 14 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
what are 4 solutions to the linear equation: 4x-3y=12?
Answer:
[tex](0;-4) (3,0); (6,4); (9,8)[/tex]
Step-by-step explanation:
You will end up with ordered pairs. the way to find them is to assign convenient values to either x OR y, and find the remaining ones. by "convenient" i would recommend having either equal to zero, and then playing with coefficients so that something else goes to "convenient" numbers - since I'm lazy and I hate typing fractions in here.
[tex]x= 0 \rightarrow 4(0) -3y=12 \rightarrow y=-4;\\y=0 \rightarrow 4x -3(0) = 12 \rightarrow x=3;\\x=6 \rightarrow 4(6)-3y=12 \rightarrow -3y=-12 \rightarrow y=4\\y= 8 \rightarrow 4x-(3)(8)=12\rightarrow 4x=36 \rightarrow x=9[/tex]
How did I choose 6 and 8? Mostly practice and a bit of good eye. 12 at the RHS is 4 times 3, and the LHS is 4 times something, minus 3 times something else, so it was a good bet that picking multiples of the other something would cancel out.
