Answer:

the fourth image

Step-by-step explanation:

y + x + 3 = 0

y = -x - 3

meaning slope = -1

and y-intercept is -3

answer: image attached

because they all look similar, it is the one that moves exactly one block per unit

11) MZHGF = 16x + 4, m EGF = 110°,<br> and MZHGE = 3x + 11. Find x.<br> G<br> H<br> F<br> E

Darya [45]

<h3>Answer: x = 9</h3>

=======================================================

Explanation:

The smaller angles HGE and EGF combine to form the largest angle HGF.

This is an example of the angle addition postulate.

(angle HGE) + (angle EGF) = angle HGF

(3x+11) + (110) = 16x+4

3x+121 = 16x+4

121-4 = 16x-3x

117 = 13x

13x = 117

x = 117/13

x = 9 which is the final answer

We can stop here.

--------------------

Extra info (optional section)

Use this x value to find each angle shown below

angle HGE = 3x+11 = 3*9+11 = 27+11 = 38 degrees
angle HGF = 16x+4 = 16*9+4 = 144+4 = 148 degrees

Then notice how,

(angle HGE)+(angle EGF) = 38+110 = 148

which is exactly the measure of angle HGF

This confirms that the equation

(angle HGE) + (angle EGF) = angle HGF

is true for that x value of x = 9. Therefore, the answer is confirmed.

Find the value of x rounded to the nearest tenth

Tomtit [17]

The figure suggests that the two sub-triangle are similar, because they are both right and the angle at the top is the same.

If that is the case, we can claim that the correspondent sides are in proportion:

$6\div 9 = x \div 8$

Solving for x we have

$x = \dfrac{6\cdot 8}{9}=\dfrac{48}{9}=\dfrac{16}{3}$
