Answer:59:95
Step-by-step explanation:
If B = x + 10 and C = x + 2 , find an expression that equals 2B + 2C in standard form.
Answer:
4x+24
Step-by-step explanation:
B = x+10
C = x+2
2B + 2C = 2(x+10) + 2(x+2) = 2x+20+2x+4 = 4x+24

What is the slope of the line that passes through the given points?
(-1, -5) and (-12, -5)
Watch out for those negative signs!
Select one:
a.
0
b.
undefined (this means you get an answer like 5/0, you CANNOT divide a number by 0!)
c.
10/13 fraction
d.
13/10 fraction
Answer:
The answer is A. 0
Step-by-step explanation:
If you graph the equation it shows a straight horizontal line and that makes it zero
Answer:
A) 0
or m = 0
Step-by-step explanation:
Slope is zero, because it's just a straight horizontal line.
You can tell when you graph it or by the fact that they both have the same y-value, in this case -5.

The equation of line j is y =-5/8x+4/9. Line k is parallel to line j. What is the slope of line k?
Answer:
using the formula
y= mx+ c
comparing these;
m= -5/8
when two lines are parallel they are always equal
so the slope of line k= -5/8

If 5x - 2y = 6 and 3x + 2y = 10, then find the value of x and y.
Step-by-step explanation:
[tex]\textsf{\large{\underline{Solution}:}}[/tex]
Given Equations:
→ 5x - 2y = 6 ----- (i)
→ 3x + 2y = 10 ---- (ii)
Adding (i) and (ii), we get:
→ 8x = 16
→ x = 16/8
→ x = 2
Substituting the value of x in (i), we get:
→ 5 × 2 - 2y = 6
→ -2y = 6 - 10
→ -2y = -4
→ y = -4/-2
→ y = 2
Therefore:
→ (x, y) = (2, 2) (Answer)
[tex]\textsf{\large{\underline{Verification}:}}[/tex]
Put x = 2 and y = 2 in first equation, the LHS becomes:
= 5 × 2 - 2 × 2
= 10 - 4
= 6
= RHS
Put x = 2 and y = 2 in second equation, the LHS becomes:
= 3 × 2 + 2 × 2
= 6 + 4
= 10
= RHS
Hence, our answer is correct (Verified)
Answer:
X= 2
Y= 2

Answer:
PLS MARK BRAINLIEST
Step-by-step explanation:
Sn = n/2(2a+(n-1)d)
a=6
a+ 4d= 18
6 +4d= 18
4d = 12
d = 3
162= n/2(12+(n -1)3)
324=n(12 + 3n-3)
324=12n + 3n^2 - 3n
3n^2 + 9n-324=0
3n^2+ 36n-27n -324 =0
3n(n+12) -27(n+12)= 0
3n-27 =0; n+ 12=0
n=9 ; n= -12
since n can't be negative n=9
The number of terms is 9
