What is -6:<br> -The coefficient <br> -The variable<br> -The constant

40 POINTS AND BRAINLIEST!! I NEED THIS DONE ASAP

inna [77]

(a) Answer: One solution.

Explanation: two lines that have same slope with opposite sign will necessarily cross each other at a single point, as one is "pointing uphill" and the other "downhill."

(b) Answer: Infinitely many solutions.

Explanation:

2x + 3y = 5.5

4x + 6y = 11 | divide by 2

-->

2x + 3y = 5.5

--> equations are identical.

2x + 3y = 2x + 3y

so any (x,y) will satisfy this equation. This means infinitely many solutions.

(c) Answer: One solution

Explanation:

Continuing the two lines it becomes obvious they will cross at one point (the solution)

(d) Answer: No solution

Explanation: If the two lines are parallel, they will never cross (by definition of "parallel"). Therefore there will be no solution to the corresponding linear system.

What’s the missing angle <br> ?

fomenos

Answer:

x=20

3x= 3(20)=60

4x= 4(20)=80

Step-by-step explanation:

The angles CD is 90 degrees because the small square indicates

it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).

so AB + 70+ 90= 180 degrees

AB= 180 -70-90

AB=20

x=20

3x= 3(20)=60

4x= 4(20)=80

The lock on a safe requires a three-digit code to open it. The three digits must each be a number from 0-9 (10 possible numbers)

vovangra [49]

The correct answer is Choice B: 720.

To solve this, you have to use the Fundamental Counting Principal. You find the total number of options for each of the digits, then multiply them together.

For the first one, there are 10 options, then 9 options and finally 8 options.

10 x 9 x 8 = 720

Jolene invests her savings in two bank accounts, one paying 4 percent and the other paying 10 percent simple interest per year.

Nostrana [21]

Answer:

<h2>$ 22200 in higher yielding bank and $ 44400 in lower yielding bank</h2>

Step-by-step explanation:

Jolene invests in two bank accounts. The first account gives a 4% interest per year and the second bank gives a 10% interest rate per year.

She puts twice as much in the lower yielding bank account. Let us denote the amount put in high yielding bank account by $x$ . Lower yielding bank account will have $2x$ .
