Step-by-step explanation:
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!
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

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]
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)>
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 accompanying diagram shows two triangles. Which proportion could be used to solve for x ?
Help please//brainliest!
Hi there!
The answer for this question is C, BD. As you can see, BC and DA are the same which means that AB and CD are also the same.
That only leads to BD which means that BD has the shortest sides.
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
