25-3x-2-4x+5 has how many coefficients and how many expressions

1 answer:

Answer:

This expression has 2 coefficients, (-3 and -4), because any number with a variable is a coefficient. That means 25, -2, and 5 are all constants, because they don't have variables.

Variables are the x's in this case.

I hope this answers your question :) Also if you like, can you mark me brainliest, please? It would really mean a lot to me :)

Answer:

B. 3

Step-by-step explanation:

To find the value of c, substitute the x and y values of the given point into x and y of the equation, then isolate c. Since that given point is (2,5), substitute 2 for x and 5 for y:

$(5) = -2(2)^2+8(2)-c\\5 = -2(4)+16-c\\5 = -8 + 16 - c \\5 = 8 -c\\-3 = -c\\c = 3$

Thus, c = 3.

<h3>Answer: choice A) </h3><h3>tan(Y) = 6/7 and tan(Z) = 7/6</h3>

Recall that the tangent of an angle is equal to the ratio of the opposite over adjacent sides

tan(angle) = opposite/adjacent

For reference angle Y, the opposite side is XZ = 6 and the adjacent side is XY = 7, so,

tan(Y) = XZ/XY = 6/7

For tan(Z), things will swap. The opposite side is now XY = 7 and the adjacent side is now XZ = 6

tan(Z) = XY/XZ = 7/6

We do not use the hypotenuse sqrt(85) at all in this problem because the tangent ratio does not involve the hypotenuse.

Natalie buys a basketball for $25.57 and an air pump for $15.61. How much change will she receive if she pays for both items wit

weeeeeb [17]

Answer:

$Change = \$8.82$

Step-by-step explanation:

Given

$Basketball = \$25.57$

$Air\ Pump = \$15.61$

$Amount = \$50$

Required

Determine the change received

First, we need to calculate the total amount spent

$Total = \$25.57 + \$15.61$

$Total = \$41.18$

This implies that Natalie pays a total of $41.18

Next, we calculate the change as thus:

$Change = Amount - Total$

$Change = \$50 - \$41.18$

$Change = \$8.82$

<em>Hence, the change is $8.82</em>
