Answer:

The form is y=mx+b where m is the slope and b is the y-intercept

1)

y=4/3x-5

2)

y=-3/2x+4

y-intercept is (0,4)

4-1/0-2=3/-2=-3/2

3)

y=-2/3x

y-intercept is (0,0)

0-(-2)/0-3=2/-3=-2/3

4)

y=2x-1

9-3/5-2=6/3=2

y-9=2(x-5)

y=2x-10+9

y=2x-1

the weight of an object on mars varies directly as the weight of the object on earth a 90 pound object on earth weighs 34 pounds
Mariulka [41]

We have been given that the weight of an object on the mars varies directly as the weight of the object on earth.  

Let y be weight of an object on Mars and x be weight of an object on Earth.

\\
y=kx

We have been given that the weight of an object on Mars is 34 pounds and weight of the same object on Earth is 90 pounds.

Putting the given values in equation we get

\\
34=k(90)\\
\\
k=\frac{34}{90}=\frac{17}{45}

Therefore, our equation now becomes

\\
y= \frac{17}{45}x

Now we have been given that the weight of an object on Earth is 135 pounds and we have to find the weight of the same object on Mars,

We have been given that \\
x=135

Putting the given values in our equation we get

\\
y= \frac{17}{45}(135)=\frac{17\cdot 135}{45}=17\cdot 3 = 51

Therefore weight of the object on Mars will be 51 pounds.

nika2105 [10]

Answer:

-2^{\circ}\text{F}

Step-by-step explanation:

Let x be the temperature on the first day

Second day temperature

x+7

Third day temperature

x+7-10

Fourth day temperature was 1^{\circ}\text{F}

x+7-10+6=1\\\Rightarrow x+3=1\\\Rightarrow x=1-3\\\Rightarrow x=-2^{\circ}\text{F}

On the first day the temperature was -2^{\circ}\text{F}
