solve for a:5(a+2)-3(2a-5)=39

Answers

Answer 1
5(a + 2) -3(2a - 5) = 39
5a + 10 - 6a + 15 = 39
Combine liked terms
-a + 25 = 39
-25 on both sides
-a = 14
a = -14

Checking if a = -14, substitute it back into the equation
5(a + 2) -3(2a - 5) = 39
5(-14 + 2) -3(2(-14) - 5)) = 39
5(-12) -3(-28 - 5) = 39
-60 -3(-33) = 39
-60 + 90 = 39
39 = 39

Answer:
a = -14

Math question pls help

Answers

Answer:

(-4) - (+2) = -6

(+6) + (+9) = -3

(-36) divide (+3) = -12

(-12) x (-8) = 20

(-4) + (-7) = -11

(+7) - (4) = 11

(-5) - (+12) = 17

(+6) + (+9) = 15

(-10) + (+12) = -22

(+6) + (+6) = 12

(+10) divide (-10) = 1

(+4) + (-5) = -20

(-10) + (-10) = -20

(-4) x (+7) = 28

(+11) + (-2) = 9

(-2) - (-3) = 1

(-7) - (+1) = -8

(+1) + (+4) = 5

Find the slope of the line that goes through (2, -1) and (6, 1).

Answers

Answer:

Slope= y=(1/2)x-2

Step-by-step explanation:

Answer:

you would use y^1-y^2/x^1-x^2

You have decided to cash in all of the coins you have been saving for the summer. In total you have $7.20. You only have dimes and quarters, and you know that you have twice as many dimes as you do quarters. How many quarters do you have in total? How many dimes? (HINT: think about what you know of dimes and quarters!)

Answers

Answer:

The number of quarters in total = 16 quarters

The number dimes = 32 dimes

Step-by-step explanation:

The given information are;

The total amount of money in held = $7.20

The denomination of the money held = Dimes and quarters

The number dimes = 2 × The number of quarters

Given that a dime = 10 cents = $0.1

A dollar = 25 cents = $0.25

Let the number of quarters in the sum of money = X

Therefore, we have;

X × $0.25 + 2 × X × $0.1 = $7.20

X × $0.25 + X × $0.2 = $7.20

X × $0.45 = $7.20

X = $7.20/$0.45 = 16

Therefore, the number of quarters = 16

The number of quarters in total = 16 quarters

The number dimes = 2 × The number of quarters = 2 × 16 = 32 dimes

The number dimes = 32 dimes.

How would you graph this correctly onto a graph?

Answers

Answer:

Here is how you graph your equations correctly :D

Step-by-step explanation:

Graph y > x − 2.

Use the slope-intercept form to find the slope and y-intercept.

Slope: 1

y-intercept: (0, -2)

Graph a dashed line, then shade the area above the boundary line since y is greater than x − 2 .

y > x - 2

Graphy < −4x + 2.

Use the slope-intercept form to find the slope and y-intercept.

Slope: -4

y-intercept: (0, 2)

Graph a dashed line, then shade the area below the boundary line since y is less than − 4 x + 2 .

y < -4x + 2

Plot each graph on the same coordinate system.

y > x - 2

Y < -4x + 2

I hope this helps.

A yield curve is a graphical representation of the relationship between the yields and the maturities of securities issued by a given borrower in a given currency on a given date. The mathematical relationship between these two variables, the yield and the maturity, is called the term structure of interest rates, and the graphical relationship (plotted curve) is called the yield curve. A yield curve can exhibit a variety of shapes, and the general shapes have been given a specific name. Identify the name of the yield curve that matches the pattern described as follows: Description of the Yield Curve Name Given to Describe the Yield Curve 1. Short-term rates are relatively low, intermediate-term rates are much higher, and long-term rates are much lower. 2. Long-term rates are greater than short-term rates. 3. The yield curve exhibits a downward-sloping curve. 4. Normal yield curve Long-term rates are equal to short-term rates.
