b.–172
c.28
d. 72

Answers

Discriminant is 28 (c) First get the equation into the form: Ax^2 + Bx + C = 0 (the quadratic equation).. By subtracting 10x both sides (to get it on the other side).. 9x^2 + 2 = 10x 9x^2 - 10x + 2 = 10x - 10x 9x^2 - 10x + 2 = 0 Now the discriminant is: b^2 - 4ac The quadratic equation is Ax^2 + Bx + C = 0 Here, A = 9, B = -10 and C = 2 (-10)^2 - 4 (9)(2) = 100 - 4 (18) = 100 - 72 = 28

Question is: Solve -7(x+6)=4(x+6)

Answers

$\huge\boxed{x=-6}$

Hey there! Our goal here is to isolate the variable on one side of the equation.

$\begin{aligned}-7(x+6)&=4(x+6)&&\smash{\Big|}&&\textsf{Start with the original equation.}\n-7x+(-7)(6)&=4x+4(6)&&\smash{\Big|}&&\textsf{Distribute.}\n-7x-42&=4x+24&&\smash{\Big|}&&\textsf{Multiply.}\n-7x-4x&=24+42&&\smash{\Big|}&&\textsf{Move the terms.}\n-11x&=66&&\smash{\Big|}&&\textsf{Combine like terms.}\nx&=\boxed{-6}&&\smash{\Big|}&&\textsf{Divide both sides by $-11$.}\end{aligned}$

Answer: The answer is x=–6.

Step-by-step explanation: Step 1: Simplify both sides of the equation:

$(-7)(x)+(-7)(6)=(4)(x)+(4 )(6)$ (Distributive Property)

$-7x+-42=4x+24$

$-7x-42=4x+24$

Step 2: Subtract 4x by the both sides: $-7x-42-4x=4x+24-4x$

$-11x-42=24$

Step 3: Add 42 to the both sides: $-11x-42+42=24+42$

$-11x=66$

And step 4: Divide both sides by -11: $(-11x)/(-11)=(66)/(-11)$ , $x=-6$ .

For the coordinates of P and M (the midpoint) are given. Find the coordinates for Q.P(-2, 3) and M (5, 1)

Answers

Given an endpoint and a midpoint, to look for the other endpoint, the midpoint formula is merely manipulated. The average of the x-coordinates for P and Q have to equate to the x-coordinate of M. The same is applied to the y-coordinates. This is shown below:

X-coordinates:

(-2 + Qx)/2 = 5
(-2 + Qx) = 10

Qx = 12

Y-coordinates:

(3 + Qy)/2 = 1
3 + Qy = 2

Qy = -1

Therefore, Q has the coordinates (12 , -1)

1/5t-3=-17

Answers

$(1)/(5) t$ - 3 = -17

First, simplify $(1)/(5) t$ to $(t)/(5)$ / Your problem should look like: $(t)/(5) - 3 = -17$
Second, multiply both sides by 5. / Your problem should look like: $t - 15 = -85$
Third, add 15 to both sides. / Your problem should look like: $t = -85 + 15$
Fourth, simplify -85 + 15 to get -70. / Your problem should look like: $t = -70$

CHECKING:
$(1)/(5) t - 3 = -17$
First, let t = -70 / Your problem should look like: $(1)/(5) x -70-3=-17$
Second, simplify $(1)/(5) x -70$ to $-(1)/(5)x70$ / Your problem should look like: $-(1)/(5) x 70-3=-17$
Third, simplify $(1)/(5) x70$ to $(70)/(5)$ / Your problem should look like: $- (70)/(5) -3=-17$
Fourth, since 14 goes into 5 to get 70, simplify the fraction by 14. / Your problem should look like: $-14-3=-17$
Fifth, simplify -14 - 3 to get -17 / Your problem should look like: $-17 = -17$

Answer: t = -70
