The points (1,7) and (0,5) fall on a particular line. What is its equation in slope-intercept

choli [55]

Answer:

y = 2x + 5

Step-by-step explanation:

First find the slope:

5-7/0-1 --> -2/-1 --> (2)

Now use the point-slope form to find the slope-intercept form:

y-7 = 2 ( x - 1)

y - 7 = 2x - 2 add seven to both sides...

y = 2x + 5

generate and solve another division problem with the same quotient and remainder as the two problems below. Explain your strateg

Zarrin [17]

Answer:

The dividend is 51 and the divisor is 13.

Step-by-step explanation:

Since the remainder is 12, so the divisor must be greater than 12.

So, we can choose any number as a divisor which is greater than 12.

Assume the divisor is 13.

So, when we divide the dividend say, x by the divisor 13 then the quotient will be 3 and the remainder will be 12.

Therefore, x = 13 × 3 + 12 = 51

So, the dividend is 51 and the divisor is 13. (Answer)

Answer:

Slope is -3

Step-by-step explanation:

(0, -2) and (1, -5)

m= (y2-y1)/(x2-x1)

m= (-5+2)/(1-0)

m=( -3)/1

m = -3

Filipo is building a rectangular sandbox . The length of the sandbox is 1 foot longer than twice the width of the sandbox .the p

Alla [95]

Answer:

Part A : D.) $2w + 2(2w+ 1) = 29$

Part B : Length of the sandbox is 10 feet.

Step-by-step explanation:

Given,

Perimeter = 29 ft

We need to find the equation for the perimeter and also the length of the sandbox.

Solution,

Let the width of the sandbox be 'w'.

Now as per question said;

The length of the sandbox is 1 foot longer than twice the width of the sandbox.

So we can say that;

Length = $2w+1$

Now we know that the perimeter is equal to the sum of twice of length and width.

framing in equation form, we get;

Perimeter = $2(2w+1)+2w$

we have given the perimeter, so on substituting the value, we get;

$29=2(2w+1)+2w$

Hence The equation used to find the width is $29=2(2w+1)+2w$ .

Now we solve for 'w'.

Applying distributive property, we get;

$4w+2+2w=29\\\\6w+2=29$

Subtracting both side by '2' we get

$6w+2-2=29-2\\\\6w=27$

Dividing both side by 6 we get;

$\frac{6w}{6}=\frac{27}{6}\\\\w=4.5\ ft$

Width of the sandbox = 4.5 ft

Length of the sandbox = $2w+1=2\times4.5 +1 = 9+1=10\ ft$

Hence Length of the sandbox is 10 feet.
