Mathematics

nataly862011 [7]3 years ago
7 0

Answer:

-2

Step-by-step explanation:

Let the number be  'x'

x - 14 = 2 + 9x

Subtract x from both sides

- 14 = 2 + 9x - x

-14 = 2 + 8x

Subtract 2 from both sides

-14-2 = 8x

 -16 = 8x

Divide both sides by 8

-16/8 = x

x = -2

Consider the function f(x)=8-3x^2 find the value of f(x) when x= 3
scoray [572]
You start with f(x)=8-3(3)². Then, going in order of PEMDAS, you start with your exponent. So you have f(x)=8-3(9). Then multiplication, f(x)=8-27. Then your subtraction. f(x)=-19

the formula y-y=m(x-x) is the point -slope from of the equation of a line where m is the slope of the line and (x,y) and ( x,y)
hodyreva [135]
(4,-2)(5,0)
slope(m) = (0 - (-2) / (5 - 4) = 2/1 = 2
there is going to be 2 possible answers...

y - y1 = m(x - x1)
now we sub

using points (4,-2)..... y -(-2) = 2(x - 4) =
y + 2 = 2(x - 4) <==

using points (5,0)....y - 0 = 2(x - 5) <==

PLEASE HELP<br><br> x = ___ units
Shkiper50 [21]

Answer:

x = <u>16</u> units

Step-by-step explanation:

∆ABC is a 45-45-90 triangle, and ∆BCD is a 30-60-90 triangle.

If side opposite of 90° [∆] = x, side opposite of 45° [∆] = x / √2 = x √ 2 / 2.

Given side AC is opposite of 90° [∆ABC] = 32 √ 2, side opposite of 45° [∆ABC] = 32 √ 2 / √ 2 = 32 which is AB or BC.

Since side BC is part of BCD.

Side opposite of 90° [∆BCD] = BC = 32.

Since x is opposite of 30° [∆BCD].

x = Side opposite of 90° [∆BCD] / 2 = 32 / 2 = 16.

What is the measure of DA? 15 90 105 165
seraphim [82]

Answer:

D. 165

Step-by-step explanation:

if A+n=180

75+90+n=180

165+n=180

n=180-165

n=15

A+n=180

A+15=180

A=180-15

A=165 (D)
