Answer:

Smaller angle: 69 degrees

Larger angle: 111 degrees

Step-by-step explanation:

Supplementary angles= two angles that make up 180 degrees

x = smaller angle

x + x + 42 = 180 Add like terms

2x + 42 = 180 Subtract 42 on both sides

2x = 138 Isolate the variable by dividing 2 on both sides

x = 69

x = smaller angle, 69 degrees

x + 42 = larger angle, 111 degrees

f varies jointly as g, h, and j. One set of values is f=18, g=4, h=3, and j=5. Find f when g=5, h=12, and j=3.

Answer:

$\boxed{60}$

Step-by-step explanation:

f ∝ ghj

Convert the proportion to an equality

f = kghj

Calculate the value of k

18 = k × 4 × 3 × 5

18 = 60k

k = ⅓

Rewrite the equation with the value of k

f = ⅓gkj

Find the new value of f

f =⅓ × 5 × 12 × 3 = $\boxed{60}$

Help me plz

irakobra [83]

Answer:

I could do 1 and 3

1) 2x-3y=-2 ....1

2x+y=14......2

=-4y=-16

y=4

Substitute (y=4) into equation 1

2x-3 (4)=-2

2x-12=-2

2x=-2+12

2x=10

×=5

3) 5x+5y=20....1

-3x+5y=4......2

=8x=16

x=2

Substitute (x=2) into equation 1

5 (2)+5y=20

10+5y=20

5y=20-10

5y=10

y=2

For this problem, there are two situations. To solve this, let's construct an algebraic equation for each. Let's find the total cost. Let x be the number of yards.

Situation 1: Cost = 4x + 5
Situation 2: Cost = 6x +2

Now, both situations have the same cost. So,

4x + 5 = 6x + 2
6x - 4x = 5 - 2
2x = 3
x = 3/2 or 1.5 yards

Find the equation of the exponential function represented by the table below:

UNO [17]

Answer:

Step-by-step explanation:

If this is an exponential function, it is of the form

$y=a(b)^x$ where x and y are coordinates from your table, a is the intial value, and b is the growth/decay rate. To find out what the equation is that represents this data, choose 2 points and solve first for a and then for b. Just a hint: If at all possible, choose the coordinate that gives you an x of 0. You'll see why in a minute.
