Find the value of x 23 34 56 14

Juliette [100K]

The two angles together form a straight angle, i.e. an angle of 180 degrees. This means that

$7x + 2x+27 = 180$

Sum like terms:

$9x+27 = 180$

Subtract 27 from both sides:

$9x = 153$

Divide both sides by 9:

$x = \dfrac{153}{9} = 17$

Nicole invested her savings in two investment funds. The amount she invested in Fund A was $3000 less than the amount she invest

victus00 [196]

Let us denote the amount of investment in the Fund B with x. We know that Fund B returned 8% and that in Fund A Nicole invested $3000 less than the amount she invested in Fund B, so we can write: x-3000Fund A returned 6%.
Interest = 2060
The percent has been converted by multiplying the equation by 100
8x+6(x-3000)= 2060*100
8x+6x-18000=206000
14x=206000+18000
14x=224000
x=16000
Nicole invested in Fund B $16000 and in Fund A $16000-3000=13000.

4) What is the present value of $4000 received at the

Bingel [31]

Answer:

$11040

Step-by-step explanation:

first of all the question says that $4000 were earned in a year and asks for what the new vale would be after the next 3 years with a discount rate of 8%.

If 1 year=$4000,then 3 years=$12000

100%-8%=92% (this happens because there is still a remaining amount that still has a cost to it),so 12000*92%=$11040

write the equaion of a line in slope-intercept form if the slope is 1/5 and the y-intercept is -9 explain please

faust18 [17]

Answer:

$y = \frac{1}{5} x - 9$

Step-by-step explanation:

The slope-intercept form is y = mx + b, where:

m = slope

b = y-intercept.

The slope (m) tells you the steepness of the line. It is the average rate of change which measures how the y-value changes for each one-unit change in the x-value. Hence, slope $= \frac{rise}{run}$ . So the given slope of 1/5 means that for every 1 unit change in the y-value, the x-value changes by 5 units (you go up 1 unit, and "run" 5 units to the right).

Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b). It is also the value of y when x = 0. Since you're given the y-intercept of -9, then that means that it is the y-coordinate of (0, b). So, it becomes (0, -9).

Now that we have our slope (m ) = 1/5, and the y-intercept (b ) = -9, we can write the equation of the line as:

$y = \frac{1}{5} x - 9$

(I'm also including a screenshot of the line where it shows the y-intercept of (0, -9) on the graph).
