Mathematics
1 answer:
Oksanka [162]3 years ago
7 0

Answer:

y = -7, x = 2

Step-by-step explanation:

x+3y=-23  (eq 1)

-x+4y=-26 (eq 2)

eq1 + eq 2

7y = -49

y = -7

Sub y = -7 into eq 1

x+3(-7) =-23

x -21 = -23

x = 2

22. Chris bought a new car for $12,500. He made a $3,000 down payment and financed the rest at an annual interest rate of 14.5%
Tatiana [17]

Answer:

Step-by-step explanation:

Purchase price (A) : $12,500

Down Payment (B): $3,000

Loan Taken (C = A - B):  $9500

D :  Interest calculation for $9,500 for 3 years P(1 + rt)

= 9500(1 + (14.5/100) * 3)

= 9500(1 + 0.145 * 3)

= 9500 * 1.435

= $13632.5

E : Interest calculation for $9,500 for 2 years P(1 + rt)

= 9500(1 + (14.5/100) * 2)

= 9500(1 + 0.145 * 2)

= 9500 * 1.29

= $12,255

Difference between D - E

= $13632.5 - $12,255

= $1377.5

Hence the answer is B i.e. $1377.5 less interest for same amount of load for 2 years vs 3 years

A parabola intersects the xxx-axis at x=3x=3x, equals, 3 and x=9x=9x, equals, 9.
hichkok12 [17]

Answer:

x=6

Step-by-step explanation:

Given the x-intercepts of a parabola: x_1=3, x_2=9

The equation of symmetry at the parabola's vertex is x=h

Where h=\dfrac{x_1+x_2}{2}

In this case,

h=\dfrac{3+9}{2}=6

Therefore, the line of symmetry of the parabola is x=6 and is also the x-coordinate of the parabola's vertex.

Naya [18.7K]
<span>No, i think the scale should be differ from one another. The scale that is used to weigh food scale tend be designed to measure the object with smaller weight so the user could accurately measure the nutrient that they could get from the food. (which usually measured below 100g) Scale for concrete blocks for the other hand, tend to be used for heavier objects</span>
