The above triangle has a right angle and a 45 degree angle. So the last angle is 45. Since both sides are the same angles, both have same length
x = 14√2
use pythagorean theorem. the middle line is 28.
use sine rule
y/sin30 = 28/sin 90
and
z/sin60 = 28/sin90
y = 14
z = 14√3

Given that (- 2, 7) is on the graph of f(x) , find the corresponding point for the function f(x + 4).

AveGali [126]

Answer:

$\boxed{\ the \ corresponding\ point\ is \ (-6,7)\ }$

Step-by-step explanation:

We know that f(-2)=7

x+4 = -2 <=> x = -6

so f(-6+4) = f(-2)=7

then the corresponding point is (-6,7)

Type ALL the steps of writing the equation of the line given the slope of the line is −4 and a point on the line is (−2,1).

Mars2501 [29]

Answer:

y = -4x - 7

Step-by-step explanation:

we use the slope intercept formula given by; y = mx + b

b = y intercept, which is when x = 0

m = slope

so they tell us the slope.. we just need to find b - the y intercept.

y = mx + b

plug in your coordinates (-2,1)

1 = -4(-2) + b

1 = 8 + b

1 - 8 = b

-7 = b

put it all together.

y = -4x - 7

#7) Solve 8c - 3c + 3 = 13.

nordsb [41]

Hello!

$\large\boxed{c = 2}$

8c - 3c + 3 = 13

Begin by combining like terms:

5c + 3 = 13

Subtract 3 from both sides:

5c + 3 - 3 = 13 - 3

5c = 10

Divide both sides by 5:

5c/5 = 10/5

c = 2.
