Solve 9 (3)x =243 for x
Answer:
x=3
Step-by-step explanation:
Do you mean 9(3)^x=243? Then the solution is:
9(3)^x=243
(3)^x=27
log₃((3)^x)=log₃(27)
x=3
Therefore, x=3

What is the measure of X , in degrees?
Answer:
71°
Step-by-step explanation:
The angle of x and angle of 109, are supplementary, which means when added they are equal to 180 degrees.
109 + x = 180
x = 180 - 109
x = 71
Answer:
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40

The Smith's 5 children need to be lined up for a family photo. In how many ways could this be done? 5 5 5! 5! 5C5 5 cap c sub 5 55
Answer:
120 ways
Step-by-step explanation:
To line 5 children up in a family photo, the number of possible arrangements is obtained by taking the factorial of the number of people on the line.
In this scenario, we have 5 ;
Recall;
n! = n(n-1)(n-2)(n - n-1)
5! = 5(5-1)(5-2)(5-3)(5-4)
5! = 5 * 4 * 3 * 2 * 1
5! = 120 ways

Step-by-step explanation:
he runs 4.2 miles x 5 days
Andrew jogs 4.2 miles every day. Andrew runs 21 miles in five days.
We have given that,
Andrew jogs 4.2 miles every day.
We have to determine how many miles he jog in five days.
What is the distance?
The extent or amount of space between two things, points, lines, etc. · the state or fact of being apart in space, as of one thing from another remoteness.
he runs
= 4.2 miles x 5 days
=21.0
Therefore Andrew runs 21 miles in five days.

A line passes through the point (4,-4) and has a slope of -4. Find
the equation of the line.
O A. y = 40 + 20
ОВ.
y = -40 + 12
OC.
y = 40 + 12
OD.
y = -43 + 20
PLEASE SOMEONE ANSWER ASAP
Answer:
y = - 4x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , then
y = - 4x + c ← is the partial equation
To find c substitute (4, - 4) into the partial equation
- 4 = - 16 + c ⇒ c = - 4 + 16 = 12
y = - 4x + 12 ← equation of line

What are the solutions of the equation?
y=-7(x-3)(x+4)
Answer:
{-4, 3}
Step-by-step explanation:
To find "solutions," you must set this function equal to zero:
y = -7(x - 3)(x + 4) = 0
and then set each factor equal to 0 separately and solve each resulting equation for x:
x - 3 = 0 yields x = 3, and
x + 4 = 0 yields x = -4

2p + 5q = 48
yng true answer po
thank you:)
Answer: p = 24 − 5 q /2
Step-by-step explanation:
Answer:
[tex]p = \frac{ - 5}{2} q + 24[/tex]
Step-by-step explanation:
Let's solve for p:
[tex]2p+5q=48[/tex]
Step 1: Add -5q to both sides.
[tex]2p+5q+−5q=48+−5q[/tex]
[tex]2p=−5q+48[/tex]
Step 2: Divide both sides by 2.
[tex] \frac{2p}{2} = \frac{ - 5q + 48}{2} [/tex]
[tex]p= \frac{ - 5}{2} q+24[/tex]

What is the surface area of the prism?
Answer:
Step-by-step explanation:
122
Answer:
125.254..
Step-by-step explanation:
The triangles are 8 inches squared each, since it gives the length and width.
Since there are two triangles, it is 16.
The bottom is 4 by 8, which is 32, the back rectangle is 4 x 8 also, which is 32.
So we now have 32 + 32 + 16.
= 64 + 16
= 80
There is that last slant rectangle, which is harder.
We need to use pythagorean theorum to find that slant length first.\
4 ^ 2 + 4 ^2 = x ^2.
16 + 16 = 32.
32's squared root is something like 5.65685424949, but we will use 5.66.
Multiply that by 8 to get 45.254........
Add 80 + 45.254 = 125.254...
