A triangle has sides with lengths of 4 yards, 10 yards, and 11 yards. Is it a right triangle?
yes
no
Answer:
no
Step-by-step explanation:
for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse
a² + b² = c²
in this problem, 4² + 10² ≠ 11²
16 + 100 ≠ 121

Find the slope of the line passing through the pair of points.
(-4,5) and (0, 2)
Answer:
y = 3/-4x + 2
Step-by-step explanation:
Answer:
slope = [tex]-\frac{3}{4}[/tex]
Step-by-step explanation:
1) To find the slope between a pair of points, use the slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through. [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. We know the line passes through (-4,5) and (0,2). So, substitute their x and y values for the formula (following the appropriate order) and solve:
[tex]\frac{(2)-(5)}{(0)-(-4)} \\= \frac{2-5}{0+4} \\= \frac{-3}{4}[/tex]
Thus, the slope is [tex]-\frac{3}{4}[/tex]
What is 5x - 3y when x equals negative 2 and Y equals 6
Answer:
-28
Step-by-step explanation:
We have the equation [tex]5x-3y[/tex] and are given that [tex]x=-2, y=6[/tex]. To solve this equation, we simply replace the variables with their real value. In action, this would be [tex]5(-2)-3(6)=-10-18=-28[/tex].

The sum of 28 and p is equal to 30 what number represents p
Answer:
2
Step-by-step explanation:
28 + 2 = 30
Answer:
p = 2
Step-by-step explanation:
28 + p = 30
Subtract 28 from both sides
p = 30 - 28
p = 2

y=−4(x+2) ^2 −1. Graph the equation
Answer:
4x^2+15
Step-by-step explanation:
1. multiply whole parenthesis by power of 2
2. gets you 4(x^2+4)-1
3.Multply and it gets you 4x^2+16-1 so it would be 4x^2+15 for your answer
4. throw that into your calculator and make sure its not on radian mode and then press graph

Which vectors represent the reflection of the vector <3, -7> across the x-axis? A. [3/7} B. [-3/7] C. <-3, 7> D. <3, 7> E. [7/-3] F. <7, -3>
Answer:
D) < 3, 7)>
Step-by-step explanation:
Explanation:-
Given that the vector < 3 , -7 >
Given the vector reflection across the x-axis
(x,y) → (x , -y)
The vector < 3,-7> →< 3, -(-7)>
< 3,-7> →< 3, 7)>

If 72 = 12x, what does x equal?
Answer:
x=6
Step-by-step explanation:
So, x is our unknown variable. An so you have to ask yourself, what times 12= 72? The answer would be 6, because 12x6=72
The proper way to do it, would be to divide 12/12 so you isolate the variable, and what you do to one side, you do to the other, so divide 72 by 12 and you get 6! Hope this helps!
