Answer:
(0,-7)
Step-by-step explanation:
the y-intercept is found when the x-value is equal to 0. In this case, we are finding a coordinate pair. First, plug in 0 for x.
7+y=4.3(0)
simplify
7+y=0
subtract 7 from both sides
y=-7
Make it an ordered pair,
(0,-7)
Answer:
Step-by-step explanation:
g(x) = -2f(x)
Vertical stretch by virtue of the factor 2
Reflection over the x-axis by virtue of the factor -1

Step-by-step explanation:
The given matrix equation is:
To find Matrix X, we need to multiply both sides of the equation by 2 to obtain:
This simplifies to;
By scalar multiplication, we multiply each entry in the matrix A by to 2 to obtain matrix X.
Answer:
<h3>A. C. E. F.</h3><h3>That is, 2, 3, 5 and 6.</h3>
Step-by-step explanation:
In geometry, <em>exterior angles are any angle place between any side of a shape and a line extended from the next side</em>, as the figure shows.
As you can see, angle 2 and 3 are formed by a side of the triangle and an extended line from the next side. Similarly, angles 5 and 6 are formed the same way. Therefore, those four are exterior angles.
Divide the numerator by the denominator and you will get 0.125
