If x=-4 then..

-8 (-4)+y=37

Multiply -8 and -4 which is 32

32+y=37

Move 32 to the right side of the equal sign and that becomes -32

Y=37-32

Solve the math 37-32=5

Y=5

Your answer would be, Point A(4, 2) is translated according to the rule (x, y) ==> (x + 1, y - 5), and then reflected across the Y- Axis.

A.). So, Point A(4, 2) is in the first Quadrant.

B.). The Co-ordinates translated Point A (5, - 3), are in the Fourth Quadrant.; Lower Right

C.). The Co-ordinates of the reflected Point A ( - 5, - 3), are in the Third Quadrant.

Reflection Across Y- Axis:

(x, y) ===> ( - x, y) ======> (5, - 3) ====> ( -5, - 3)

Reflection:

(x, y) ====> ( x + 1, y - 5) =====> ( 4, 2) =====> (5, - 3)

Y - Axis =======> l ======> A

X - Axis l =======> A =======> l =======> A

Hope that helps!!! : )

-7m+4< -45 for solving an inequality

worty [1.4K]

Solving the inequality $-7m+4< -45$ we get $m>7$

Step-by-step explanation:

We need to solve the inequality: $-7m+4< -45$

Solving:

$-7m+4< -45$

Adding -4 on both sides:

$-7m+4-4< -45-4$

$-7m< -49$

Divide both sides by -7 and reverse the inequality:

$\frac{-7m}{-7}>\frac{-49}{-7}$

$m>7$

So, solving the inequality $-7m+4< -45$ we get $m>7$

Rate of change y=5x+10

frozen [14]

Answer:

Step-by-step explanation:

The equation $y=5x+10$ is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format $y=mx+b$ , such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,

$y = mx + b\\\\m=slope\\b = y-intercept.$

The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation $y=5x+10$ is given in the slope-intercept form, and the coefficient ( $m$ ) equals ( $5$ ), therefore the slope is ( $5$ ).

Please help me! I need the answer pretty fast...

lukranit [14]

Answer:

15 m

Step-by-step explanation:

you would use a sin equation because given the angle, the side you are resting to find is Opposite and the side you are given is the Hypotenuse

sin (32) = a/28

28 x sin (32) = a

14.83 = a

15 m = a when rounded
