Step-by-step explanation:
if x is equal to - 1
Then
2x² + 5x + 6
= 2* ( -1)² + 5 * (- 1) + 6
= 2 - 5 + 6
= 8 - 5
= 3
Hope it will help :)❤
Answer:
if x=-1
then
2(-1)2+5(-1)+6
2(1)+5(-1)+6
2-5+6
X=+3
Decide whether each equation is true for all, one, or no values of x.
1) 6x - 4 = -4 + 6x
6x -6x = -4+4
0 = 0
ans - true
2) 4x -6 = 4x + 3
4x-4x = 3+6
0 = 9
Ans - false
3) -2x+4=-3x+4
-2x + 3x = 4 - 4
x = 0
ans - false
What is an equation of the line that passes through the point (7,-7) and is perpendicular to the line x-2y=2x−2y=2?
Answer:
y=−2x+7
Step-by-step explanation:
The other moron doesn't understand simple math.
An equation of the line that passes through the point (7,-7) and is perpendicular to the line x - 2y = 2 will be 2x + y = 0.
What is Slope of Line ?We have the given line x - 2y = 2 which is in form ax + by = c As we know that slope of line ax + by = c will be -(a/b).
Therefore For given line x -2y = 2 value of a will be 1 and value of b will be -2. Therefor Slope of given line will be -(a/b) = -(1/-2) = 1/2.
Now As we know that slope of two lines which are perpendicular to each other has product of there slopes as negative of unity that is -1.
Let the slope of line which we have to find be m also we have slope of given line as 1/2.
∴ m(1/2) = -1
∴ (m/2) = -1
∴ m = -1(2)
∴ m = -2.
Now as we know that line passes through the point given as (7,-7) and has slope m = -2.
Therefore equation of a line passing through a point (x₁, y₁) and have slope m will be given as
y - y₁ = m(x - x₁)
∴ y - (-7) = -2(x - 7)
∴ y + 7 = -2x -(-7)
∴ 2x + y = 7 - 7
∴ 2x + y = 0

A triangular pane of glass has a height of 42 inches and an area of 546 square inches. What is the length of the base of the pane?
Answer:
Base = 26 in
Step-by-step explanation:
Recall the formula for the area of a triangle as:
Area = (Base x Height) / 2
In our case, this formula converts into:
546 in^2 = Base x 42 in /2
multiply both sides by 2 to get rid of fractions:
1092 in^2 = Base x 42 in
divide both sides by "42 in" to isolate the Base completely
1092 in^2 / 42 in = Base
Therefore Base = 26 in

what is 12.5% of 40?
Answer:
5
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
Solution for What is 12.5 percent of 40:
12.5 percent *40 =
(12.5:100)*40 =
(12.5*40):100 =
500:100 = 5
Now we have: 12.5 percent of 40 = 5
Question: What is 12.5 percent of 40?
Percentage solution with steps:
Step 1: Our output value is 40.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$40=100\%$.
Step 4: Similarly, $x=12.5\%$.
Step 5: This results in a pair of simple equations:
$40=100\%(1)$.
$x=12.5\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{40}{x}=\frac{100\%}{12.5\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{40}=\frac{12.5}{100}$
$\Rightarrow x=5$
Therefore, $12.5\%$ of $40$ is $5$
