A (-1,2)
using substitution:
substitute-2x for y in the second function
7x - 8(-2x) = -23
solve for x
7x + 16x = -23
23x = -23
x = -1
plug x = -1 into a function to find y, in this case ill plug it into the first
y = -2(-1)
y = 2
since x = -1 and y = 2
the answer is A (-1,2)
Answer:
x = 88.463°
Step-by-step explanation:
We are given a trigonometric equation and we need to find out the value of x. The angle x lies between 0° and 360° . That is ,
<u>Given</u><u> </u><u>trigonometric</u><u> equation</u><u> </u><u>:</u><u>-</u><u> </u>
Subtracting 1 both sides , we have ,
Divide both sides by 5 ,
This equation can be written as ,
Answer: A) 112cm^3
Use the pyramid formula: v= length × width × height / 3
Plug in the equation to formula
V= 8 × 7 × 6 / 3
Multiply and divide and you get 112 cm^3
Answer:
<6 and <3 are congruent to <1.
Answer: $160 billion
Step-by-step explanation:
The government purchases multiplier refers to the increase in real GDP in dollar terms as a result of a dollar of government purchases in the economy. For instance, if the multiplier is 5 and the government spends $10, real GDP increases by: 5 * 10 = $50
The gap here is $800 billion. Given a government purchases multiplier of 5.0, the amount that the government needs to spend is:
= Gap / Multiplier
= 800 / 5
= $160 billion
