Answer:

5

Step-by-step explanation:

When squaring the number 5 (i.e 5^2 ) the answer is 25. 5^{2} is the same thing as 5 times 5. Basically with the square root, you are going backwards, so you are therefore finding the base of it all.

PLEASE ANSWER QUICKLY I WILL MARK BRAINIEST AND 70 POINT
kykrilka [37]

a) You are given the rate as 7.4m/min,

The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.

b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.

c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:

41.36 = 7.4t

To solve for t, divide both sides by 7.4:

t = 41.36 / 7.4

t = 5.59 minutes ( 5 minutes and 35 seconds)

Solve the equation -4x + 7 y equals 20. Y=3x+15
satela [25.4K]

Substitue what y equals for y and solve.

-4x+7(3x+15)=20 \\-4x+27x+105=20 \\23x=-85 \\x=-\boxed{\frac{85}{23}}

Hope this helps.

Please help me asap..!<br><br> ty :)
Elena-2011 [213]

Answer:

y-inctercept=4, x-intecept=7

Step-by-step explanation:

I did it with the standard to slope again!

7y=28-4x

y=4-\frac{4}{7}x

Now don't get confused here, 4 is the y incetecept, not -4.

When y=0, x=7

UPDATE:

To determine x and y intercept using graph, see where the line intersects at the x or y axis.
