Answer:

x=11

Step-by-step explanation:

First, we know that "supplementary" angles add up to 180 degrees. With this in mind, we can plug the values from your model into an equation:

(7x+33)+70=180

To solve this, first drop the parentheses because nothing is being distributed to the values inside them:

7x+33+70=180

Now we combine like terms, adding the 33 and the 70.

7x+103=180

Let's get rid of the 103 by subtracting it from both sides:

7x=77

Now we divide both sides by 7:

x=11

HTH :)

The answer is B. 2y+3
this is proven by multiplying the divisor of the original question and the solution
$(y-5)(2y+3)
 2y^{2}+3y-10y-15
 2y^{2}-7y-15$

A cube shaped box has a volume of 27 cubic inches bethany says each side of the cube measures 9 inches because 9 x 3 = 27. Is be

borishaifa [10]

Answer:

Step-by-step explanation:

The volume of the box is the product of its three dimensions, length, width, and height. The product of a number of "inches" and a "pure number" (3 has no units given) will not be "cubic inches."

_____

As it happens, the cube-shaped box with a volume of 27 cubic inches will have a height of 3 <em>inches</em> and a side area of 9 <em>square inches</em>. The edge length of the cube is 3 inches, not 9.

= 2. Given the quadratic equation 3x2 – 8x + k = 0 has no real roots. Find the range of values of k.

VashaNatasha [74]

$\text{If there are no real roots, then}\\\\~~~~~\text{Discriminant} < 0\\\\\implies b^2 -4ac < 0\\\\\implies (-8)^2 -4 \cdot 3 k < 0\\\\\implies 64-12k < 0\\\\\ \implies 12k > 64\\\\\implies k > \dfrac{64}{12}\\\\\implies k > \dfrac{16}3\\\\\text{Interval,}~ \left( \dfrac{16}3, ~\infty\right)$

Hey can you please help me posted picture of question

From the graph we can observe that G(x) is obtained by shifting F(x) 3 units to the left and 1 unit upwards.

Thus, both horizontal and vertical translations are involved. Horizontal translation of 3 units to left can be obtained by adding 3 to x in the equation and vertical translation of 1 can be obtained by adding 1 to the entire function.

So,

G(x) = F(x+3) + 1

G(x) = (x+3)² + 1

Thus the correct answer is option C
