I assume by the question mark that you are asking is 18 is the coefficient, If that is what you mean than you are right the coefficient is the number thetas with the variable for example 6x+y=14 the coefficient is 6 because it accompanies a variable.
Answer:
150
Step-by-step explanation:
1/2 multiply base times hieght
Answer:
Simplifying
3k(k + 10) = 0
Reorder the terms:
3k(10 + k) = 0
(10 * 3k + k * 3k) = 0
(30k + 3k2) = 0
Solving
30k + 3k2 = 0
Solving for variable 'k'.
Factor out the Greatest Common Factor (GCF), '3k'.
3k(10 + k) = 0
Ignore the factor 3.
Subproblem 1
Set the factor 'k' equal to zero and attempt to solve:
Simplifying
k = 0
Solving
k = 0
Move all terms containing k to the left, all other terms to the right.
Simplifying
k = 0
Subproblem 2
Set the factor '(10 + k)' equal to zero and attempt to solve:
Simplifying
10 + k = 0
Solving
10 + k = 0
Move all terms containing k to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + k = 0 + -10
Combine like terms: 10 + -10 = 0
0 + k = 0 + -10
k = 0 + -10
Combine like terms: 0 + -10 = -10
k = -10
Simplifying
k = -10
The wrestler's weight before he went on his diet is 78 kg
<h3>How to find the y-intercept?</h3>
The formula for slope is;
m = (y2 - y1)/(x2 - x1)
Thus, using two points we have;
m = (93.6 - 85.8)/(3 - 1.5)
m = 5.2
At the start of his diet, time in months = 0 months and so x = 0. Thus;
5.2 = (85.8 - y0)/(1.5 - 0)
5.2 * 1.5 = 85.8 - y0
y0 = 85.8 - (5.2 * 1.5)
y0 = 85.8 - 7.8
y0 = 78 kg
Thus, the wrestler's weight before he went on his diet is 78 kg

Answer:
1) triangles are similar
Step-by-step explanation:
The height from vertex X of isosceles ∆WXY is 4 units. The width WY is also 4 units. In isosceles ∆UVW, the height from vertex V is 6 units, and the width UW is also 6 units.
The height ratios are ...
∆WXY/∆UVW = 4/6
The width ratios are ...
∆WXY/∆UVW = 4/6
The measures of ∆WXY are proportional to those of ∆UVW, so the triangles are similar.
_____
Strictly speaking, you cannot go by triangle height and width alone. That is why we made not of the fact that the triangles are <em>isosceles</em>. When base and height of an isosceles triangle are proportional, the Pythagorean theorem guarantees that side lengths are proportional. Trigonometry can also be invoked to support the claim that angles are congruent.
