Answer:
-13/2
Step-by-step explanation:
Answer:
P = -6.5
Step-by-step explanation:
Multiply -2 x p and -2 x -1
The equation now is -2p + 2 = 15
Subtract the 2 to both sides to cancel it out
The equation now is -2p = 13
Divided both sides by -2 to isolate the p variable
p = -6.5
You can check your answer by subtracting -6.5 by -1 (which equals -7.5)
And then multiply -7.5 by -2 which equals 15

Solve the system of equations by substitution. y = 2x y = x +1
Step-by-step explanation:
y = 2x
y = x + 1
y-1 = x
y = 2x
y = 2 (y - 1)
y = 2y - 1
y = -1

Give 1 other example where quadratics (parabolas) might
be used by a career?
Answer:
Agriculture
Step-by-step explanation:
Quadratic equations are also used in agriculture. One of these uses is in finding out the optimal arrangement of boundaries to produce the biggest fields and pens given the materials on hand. Area is the length of a surface multiplied by its width. This turns calculations involving areas into quadratic equations.

Solve for x
Please show the steps
The answer is 10
Answer:
x = 10
Step-by-step explanation:
Since ΔCDE ~ ΔQRS, we can find the actual length of x + 8 first before finding the value of x.
Length of x + 8 = [tex]\frac{12}{20}[/tex] × 30
= 18
x + 8 = 18
x = 18 - 8
x = 10

Is the point (10,-2) a solution to the equation y = -2x + 16? Explain,
??? pls answer
Answer:
no
Step-by-step explanation:
y = -2x + 16
-2 = -2(10) + 16
-2 = -20 + 16
-2 = -4
which is wrong
Plug the point (10,-2) into y = -2x + 16 and solve. If the equation is a true, then yes, it is a point on the equation.
y = -2x + 16 > -2 = -2(10) + 16
Now, solve.
-2 = -2(10) + 16 > -2 = -20 + 16 - Start by multiplying out parenthesis.
-2 = -20 + 16 > -2 = -4 - Add.
-2 = -4
The equation cannot be simplified any further. Since -2 is not equal to -4, we can conclude that no, (10,-2) is not a solution to the equation y = -2x + 16.
