What is the value of the expression 3x+9 if x=6
Answer:
27
Step-by-step explanation:
3(6)=18
18+9=27
Answer:
27
Step-by-step explanation:
You would use PEMDAS to solve this equation, P (parenthesis) E (exponates) M (multiply) D (divide) A (add) S (subtract). The way you use this is by following the steps in the order that you would spell PEMDAS, so 3x+9 would be 3•6+9. So look at the equation 3•6+9, so what would we use first? do we have parenthesis? No, Do we have exponents? No, Do we have multiplication? Yes, so multiply 3 and 6 = 18. Now the equation will look like this 18+9 = 27.
Hope this helps!

Gina has saved $385 for music lessons. She plans to spend $35 per month 5 points
on lessons. This can be represented by the equation y = 385-35x where y
is the amount of money she has left and x is the number of months she
has been taking music lessons. What is the x-intercept? What does the x-
intercept of this function mean in the context of this situation?
Answer:
11, the amount of time it'll take for her to run out of money for music lessons
Step-by-step explanation:
THe x intercept is where y=0
to solve this we can just plug in 0 for y and solve for x
we have
0= 385-35x
35x=385
x=11
Answer:
x- intercept is when y = 0
y = 385 - 35x0 = 385 - 35x35x = 385x = 385/35x = 11This is the point (11, 0), this is the indication that after 11 months Gina will have spent all money saved.

I need help with solving systems of linear equations through elimination.
1.) 8x = 3y + 38
24= 6y + 9x
a. all real numbers
b. (4,-2)
c. (4,-4)
d. (6,3)
2.) 6 = 2x + y
7x = 3 - 3y
a. (15,-36)
b. (-5,6)
c. (0,0)
d. (-15,36)
3.) 11x = 5 + 10y
7y = -2x +45
a. (-5,10)
b. (5,5)
c. (14, -4)
d. No solution
Answer:
See explanation
Step-by-step explanation:
8x = 3y + 38
24= 6y + 9x
Rearrange;
3y - 8x = -38 * 2 -------(1)
6y + 9x = 24 * 1 -------(2)
6y - 16x = -76 -------(3)
6y + 9y = 24 -------(4)
Subtract (4) from (3)
-25y = -100
y= 100/25
y = 4
Substitute y =4 into(1)
3y - 8x = -38
3(4) - 8x = -38
12 -8x = -38
-8x = -38 - 12
x = 50/8 = 6 2/8
2) 6 = 2x + y
7x = 3 - 3y
Rearrange;
2x + y = 6 * 3 --------(1)
7x + 3y = -3 * 1 --------(2)
6x + 3y = 18 ---------(3)
7x + 3y = -3 ---------(4)
Subtract (4) from (3)
-x = 21
x = -21
Substitute x = -21 into (1)
2x + y = 6
2(-21) + y = 6
-42 + y = 6
y = 6 + 42
y = 48
3)
11x = 5 + 10y
7y = -2x +45
Rearrange
11x - 10y = 5 * 2 ---------(1)
2x + 7y = 45 * 11 ---------(2)
22x - 20y = 10 --------(3)
22x + 77y = 495 --------(4)
Subtract (4) from (3)
-97y = -485
y = 5
Substitute y =5 into (1)
11x - 10y = 5
11x - 10(5) = 5
11x - 50 = 5
11x = 5 + 50
11x = 55
x = 55/11
x = 5

EASY QUESTION OF THE DAY (whoever answers first gets brainly!)
Answer:
she would be spening over a thousand dollars
Step-by-step explanation:
Asnwer:
10,920$
Step-by-step explanation:
So if 3.00$ is for one pack and she wants 7 packs then it would be 21$.
But if we also multiply it by 52 weeks then that would be 1,092$.
Then if she's buying that for 10 years then we multiply 10 x 1,092$ which would equal 10,920$

Determine whether each pair of figures is similar. If so, write the similarity statement and scale factor. If not, explain why. Number 1 and 2 on the second part.
9514 1404 393
Answer:
JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5Step-by-step explanation:
We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.
1. JKLM ~ QRSP
JK : KL : LM : MJ = 20 : 15 : 24 : 25
QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)
The scale factor is 12/20 = 0.6.
__
2. ΔABC ~ ΔUVT
AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6
UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)
The scale factor is 24/16 = 1.5.
