Answer:

A. 55°

B. 71°

C. 100°

D. 65°

E. 120°

F. 155°

G. 147°

H. 36°

I. 70°

J. 54°

K. 24°

L. 40°

Step-by-step explanation:

A. 180 - (90 + 35) = 55°

B. 180 - (34 + 75) = 71°

C. 180 - (43 + 38) = 100°

D. 180 - 50 = 130 / 2 = 65°

E. 180 - (90 + 30) = 60°

180 - 60 = 120°

F. 180 - (120 + 35) = 25°

180 - 25 = 155°

G. 180 - 145 = 35 + 112 = 148°

H. 180 - (40 + 26) = 144°

180 - 144 = 36°

I. 180 - (60 + 65) = 125°

180 - 125 = 55°

180 - (55 + 50) = 75°

180 - (75 + 35) = 70°

J. 180 - 116 = 64°

180 - (64 + 62) = 54°

K. 180 - (138 +18) = 24°

L. 180 - (80 + 60) = 40°

Solve the system below using elimination {5x+9y= -10} {7x+10y= -1}

bixtya [17]

∑Hey , jillianwagler ⊃

Answer:

x = 7, y = -5

Step-by-step explanation:

Given~:

Solve the system below using elimination

{5x+9y= -10}

{7x+10y= -1}

Solve:

$\begin{bmatrix}5x+9y=-10\\ 7x+10y=-1\end{bmatrix}$

Isolate x ( 5x + 9y = -10 ) : $\mathrm{x=\frac{-10-9y}{5}}$

Substitute: $\mathrm{x=\frac{-10-9y}{5}}$

$\begin{bmatrix}7\cdot \frac{-10-9y}{5}+10y=-1\end{bmatrix}$

$\begin{bmatrix}\frac{-70-13y}{5}=-1\end{bmatrix}$

Isolate y : $\frac{-70-13y}{5}=1:y=-5$

Substitute: $y=-5$

$x=\frac{-10-9\left(-5\right)}{5}=7$

Hence, $x=7$

Therefore, the solution for $\begin{bmatrix}5x+9y=-10\\ 7x+10y=-1\end{bmatrix}$ are:

$x=7,\:y=-5$

An open top box is formed by cutting squares out of a 5 inch by 7 inch piece of paper and then folding up the sides. The volume

Radda [10]

Answer:

$V(x) = 4x^3 - 24x^2+35x$

Step-by-step explanation:

Given

$V(x) = (7 - 2x)(5 - 2x)(x)$

Required

Expand the expression

$V(x) = (7 - 2x)(5 - 2x)x$

Expand bracket

$V(x) = (7 - 2x)(5 * x - 2x * x)$

$V(x) = (7 - 2x)(5x - 2x^2)$

Further expand bracket

$V(x) = 7(5x - 2x^2) - 2x(5x - 2x^2)$

$V(x) = 35x - 14x^2 - 10x^2 + 4x^3$

$V(x) = 35x - 24x^2 + 4x^3$

$V(x) = 4x^3 - 24x^2+35x$

use a method of completing the square in order to rewrite the function f(x)=x^2+5x-2 in vertex form, f(x)=a(x-h)^2+k where (h,k)

yuradex [85]

      f(x) = x² + 5x - 2
f(x) + 2 = x² + 5x - 2 + 2
f(x) + 2 = x² + 5x
f(x) + 2 = x(x) + x(5)
f(x) + 2 = x(x + 5)
      f(x) = x(x + 5) - 2
   (h, k) = (-5, 2)
