-2-3=-5
-5-(-4)=-1
This is because when you have two negative signs together, you add them!
-2-3-(-4)=-1

Which linear function represents the line given by the point-slope equation y + 7= -2/3 (x+6)

kumpel [21]

$y + 7 = - \frac{2}{3}(x + 6) \\$

$y + 7 = - \frac{2}{3}x - 4 \\$

Subtract sides -7

$y = - \frac{2}{3}x - 4 - 7 \\$

Thus ;

$y = f(x)= - \frac{2}{3}x - 11 \\$

So the correct answer is (( A )) .

55) A dilation of scale factor of 4 will produce a congruent figure True or False

vivado [14]

Answer:

False

Step-by-step explanation:

When a figure is dilated by a scale factor of 4, the new figure produced will be 4 times the size of the original figure. This means that, the size would change while the shape remains the same as the original figure.

Congruent figures must have the same shape and size.

Therefore, the figure produced when a dilation of scale factor of 4 is done is not a congruent figure. Rather, it is a similar figure.

So, get statement is FALSE.

Point C is the Image of C (-4,-2) under a Reflection across the x-axis.

Svetradugi [14.3K]

Step-by-step explanation:

$\text {Reflection Rule for across the X-axis: } (x,y) \rightarrow (x,-y)$

Using the point C (-4,-2) and the refection rule:

$(-4,-2) \rightarrow(-4, 2)$

$\text {C' should be (-4,2)}$

Find the zeros of the function: f(x) = x^2 - 4x - 21

IrinaK [193]

Answer:

x = 7, x = -3

Step-by-step explanation:

We can find the zeros by factoring the equation using the zero product property.

x^2-4x-21 = 0

(x-7)(x+3) = 0

x-7 = 0

x = 7

x+3 = 0

x = -3

Zeros are x=7 and x= -3.
