-5x-3y = -7
5x+3y=7
y=(7-5x):3
1. x=0,=>y=7/3=2 1/3 =>(0;2 1/3)
2.y=0,=>(7-5x)=0,=>x=7/5=1,4 =>(1,4;0)
3.x=1, =>y=2/3,=>(1;2/3)
Answer:
i dont know sorry im doing a test and i also eed the answer :/

Answer:
10
Step-by-step explanation:
Means back the numbers into multiples of several small numbers
Like:; 1. We take LCM of 40
Just break into multiples of small number
40= 2×2×2×5
2. We take LCM of 50
50= 5×5×2
So LCM for 100 is 2×2×5×5
after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)
Then write the the single number in place of two multipled numbers
Like:; 2×2 is written as 2 // 3×3 is written as 3
So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)
write pairs in single number 2×5
And so we get 2×5=10
So we find root of 100 that is 10
I think it the answer is A.) 440.32
50,150 / 1,000 = 50.15
50.15 x 8.78 = 440.317 or 440.32
Answer:
h(5) = - 22
Step-by-step explanation:
Given that h is a linear function say, h(x) = ax + b ......... (1)
Now, given that h(1) = 10 and h(3) = - 6
Hence, we can write from equation (1), a(1) + b = 10, ⇒ a + b = 10 .......... (2)
And a(3) + b = - 6, ⇒ 3a + b = - 6 ........ (3)
Now, solving equations (2) and (3) we get (3a - a) = - 6 - 10
⇒ 2a = - 16
⇒ a = - 8
So, from equation (2), we get, b = 10 - a = 18
Therefore, the linear function is
h(x) = - 8x + 18
Hence, h(5) = - 8(5) + 18 = - 22 (Answer)
