Well i'm gonna be honest : my answer probably is wrong, but here ya go :

so since the y intercept of f(x) is -2 translating that 6 units upwards will make it positive 4

so if six units upwards takes it to g(x) the answer should be 4

Ok so the formula they gave you is in the form y=mx+b. What's different however is that they say the graph is translated up 6 units. So the formula f(x)=-4x-2 becomes f(x)=-4x+4 (since b represents how high the graph is). And to find any y intercept, you must make X zero, and -4(0) +4 is now equal to 4 and 4 is your answer

If sinX= 0.9, what is the value of cos X? Round the value to the nearest thousandth.

SSSSS [86.1K]

Answer: sqrt(19)/10

Step-by-step explanation:

sinx=0.9

x=arcsin(0.9)

Insert x for cos(x):

cos(arcsin(0.9)=

Use identify $cos(arcsin(x))=\sqrt{1-x^{2} }$ , so

$\sqrt{1-(\frac{9}{10})^{2}} =\sqrt{\frac{19}{100} } =\frac{\sqrt{19}}{10}$

Sorry if this is confusing.

Help me to answer this pls

The 6 angles with vertex P are:

Angle APB
Angle APC
Angle APD
Angle BPC
Angle BPD
Angle CPD

The letter P must be in the middle since this location is the vertex. Something like angle BPA is the same as angle APB. We can swap the order of the outer letters without any change to the angle itself. Effectively, this means each angle has two possible names.

L 5.2.3 Quiz: Two-Variable Systems: Substitution

Misha Larkins [42]

Answer:

We get x=3 and y=21

The ordered pair will be: (3,21)

Step-by-step explanation:

We need to use the substitution method to solve the system of equations.

$y = 10x-9\\y = x + 18$
