Draw lines to match each equation on the left to its number of solutions on the right.
Answer:
1) The equation [tex]2(4x-1)=-8x-2[/tex] has one solution
2) The equation [tex]2(4x-1)=8x-2[/tex] has infinitely many solutions
3) The equation [tex]-2(4x-1)=-8x-2[/tex] has no solution.
Step-by-step explanation:
We need to solve the equation and match with its solution.
1) [tex]2(4x-1)=-8x-2[/tex]
Solving and finding value of x:
[tex]2(4x-1)=-8x-2\\8x-2=-8x-2\\8x+8x=-2+2\\16x=0\\x=0[/tex]
So, We get x =0
So, the equation [tex]2(4x-1)=-8x-2[/tex] has one solution
2) [tex]2(4x-1)=8x-2[/tex]
Solving the equation and finding value of x:
[tex]2(4x-1)=8x-2\\8x-2=8x-2\\8x-8x=-2+2\\0=0[/tex]
So, We get 0 =0
So, the equation [tex]2(4x-1)=8x-2[/tex] has infinitely many solutions
3) [tex]-2(4x-1)=-8x-2[/tex]
Solving the equation and finding value of x
[tex]-2(4x-1)=-8x-1\\-8x+2=-8x-2\\-8x+8x=-2-2\\0\neq -4[/tex]
So, we get 0 ≠ -4
So, the equation [tex]-2(4x-1)=-8x-2[/tex] has no solution.

Step 1: Define Systems
3x + 4y = -22
7x + y = 7
Step 2: Rewrite Systems
7x + y = 7
Subtract 7x on both sides: y = 7 - 7xStep 3: Redefine Systems
3x + 4y = -22
y = 7 - 7x
Step 4: Solve for x
Substitution
Substitute in y: 3x + 4(7 - 7x) = -22Distribute 4: 3x + 28 - 28x = -22Combine like terms: -25x + 28 = -22Subtract 28 on both sides: -25x = -50Divide -25 on both sides: x = 2Step 5: Solve for y

The amount for NET PAY for this pay period was $
Answer:
240.62$
Step-by-step explanation:
$9.75 per hour
30 hours
Total earned: 292.5$
Federal income tax (withholding) at 10% --> 29.5$
Social Security tax at 6.2% --> 18.14$
Medicare tax at 1.45% --> 4.24$
292.5 - all taxes = 240.62$
Why do you think the Court ruled differently in New York Times Co. v. United States (1971) than it did in Schenck v. United States (1919)? Consider differences in the ideological composition of the Court and public opinion towards the wars.
Answer:
The case reached the Supreme Court in June 1971. The Supreme Court has, at times, ruled that the government can restrict speech that presents a “clear and present danger.”

Casey's drill team squad was responsible for painting props for a performance at a band contest. The squad painted 18 props in 90 minutes. If they continued painting at this rate, how many props would they paint in 3 hours?
Answer: They would paint 36 props in 3 hours.
Step-by-step explanation:
Given: The squad painted 18 props in 90 minutes.
Time taken to paint each prop = [tex]\dfrac{90\text{ minutes}}{18}[/tex]
= 5 minutes
Now, 1 hour = 60 minutes
3 hours = 3 x 60 minute = 180 minutes
Total props painted in 3 hours = (180 )÷5
= 36
Hence, with same rate , they would paint 36 props in 3 hours.
Simplify 3 ( x + 2 ) − 2 ( x 2 + 2x − 4 ).
Which of the polynomials below represents the answer written in standard form?
Select one:
a. - 2x 2 − x + 14
b. - 2 + 7x + 2x 2
c. - 3x 4 + 14
d. 2x 2 + 7x − 2
Answer:
The polynomials that represents the answer is -2x² - x + 14 ⇒ a
Step-by-step explanation:
Let us solve the question
∵ The expression is 3(x + 2) - 2(x² + 2x - 4)
→ Multiply each bracket by the number before it
∵ 3(x + 2) = 3(x) + 3(2)
∴ 3(x - 2) = 3x + 6
∵ 2(x² + 2x - 4) = 2(x²) + 2(2x) + 2(-4)
∴ 2(x² + 2x - 4) = 2x² + 4x + (-8)
→ Remember (+)(-) = (-)
∴ 2(x² + 2x - 4) = 2x² + 4x - 8
∴ 3(x + 2) - 2(x² + 2x - 4) = (3x + 6) - (2x² + 4x - 8)
→ Multiply the (-) by all the terms in the 2nd bracket
∴ 3(x + 2) - 2(x² + 2x - 4) = 3x + 6 - 2x² - 4x + 8
→ Add the like terms
∵ 3(x + 2) - 2(x² + 2x - 4) = -2x² + (3x - 4x) + (6 + 8)
∴ 3(x + 2) - 2(x² + 2x - 4) = -2x² + (-x) + 14
∴ 3(x + 2) - 2(x² + 2x - 4) = -2x² - x + 14
∴ The polynomials that represents the answer is -2x² - x + 14

13x + 2 = 41
List the steps to fom 13x + 2
Answer: 13x + 2 = 41 = 3
Step-by-step explanation:
Step 1: Subtract 2 from both sides.
13x+2−2=41−2
13x=39
Step 2: Divide both sides by 13.

______________________________
1.) Subtract 14 from both sides:[tex]14-14=[/tex] Cancels Out[tex]39-14=25[/tex]- We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see.
Equation at the end of Step 1:
[tex]v[/tex] ÷ [tex]-0.8=25[/tex]2.) Multiply both sides by −0.8:[tex]-0.8[/tex] × [tex]-0.8=[/tex] Cancels Out[tex]25[/tex] × [tex]-0.8=-20[/tex]______________________________

If interest is compounded semi-annually, which expression represents the account balance in t yeats?
Answer:
ANNUAL Compounding : Total = Principal * (1 + rate)^years
Semi-Annual TOTAL = Principal * (1 +rate/n)^n*years
where "n" is the number of compounding periods per year
So the formula for semi-annual compounding is
TOTAL = Principal * (1 +rate/t)^t*years

Solve the equation for b. *
(50 Points)
12 = 6 (8) + b
Enter your math answer
Answer:
B=-36
Step-by-step explanation:
First, do 6(8), which equals 48
The you subtract 48 from both sides, which leaves you with:
-36=B
Answer:
b is equal to negative thirty-six.
Step-by-step explanation:
You can solve this by first multiplying the six and the eight. Eight times six is equal to forty-eight. You can then subtract that forty-eight from both sides, leaving you with the expression b = -36:
[tex]12 = 6(8) + b\\12 = 48 + b\\12 -48 = 48 + b - 48\\-36 = b\\b = -36[/tex]

Step-by-step explanation:
i guess this should be the abswer
Answer: e = -2
Step-by-step explanation:
first, i removed the parentheses.
6 + 0.75e = 2 - 1.25e
then, i moved the terms.
0.75 e + 1.25e = 2 - 6
next, i collected the like terms and calculated them.
2e = -4
finally, i divided both sides.
e = -2
