Answer:

I got 17.

Step-by-step explanation:

Because it takes 4 days to make 20 small frames, it takes 8 days to make 40. And because it takes 3 days to make 21 frames, and 21 multiplied by 3 is 63 (one less than 64), it would take 9 days (3 times the amount for 21) to make 64 large frames. In all, it would take APPROXIMATELY 17 days (9 +8 is 17)

Find the point 3x - 7x₂ =5. of the lines x, - 5x2 = 1 and of intersection
tia_tia [17]

Answer:

(\frac{9}{4},\frac{1}{4})

Step-by-step explanation:

We are given that two lines

x_1-7x_2=5 and x_1-5x_2=1

We have to find the intersection point of two lines

Let 3x_1-7x_2=5 (equation 1)

x_1-5x_2=1 (Equation 2)

Multiply equation 2 by 3 then subtract  from  equation 1

-7x_2+15x_2=5-3

8x_2=2

x_2=\frac{2}{8}=\frac{1}{4}

Substitute x_2=\frac{1}{4} in the equation 1

Then, we get

3x_1-7\frac{1}{4}=5

3x_1-\frac{7}{4}=5

3x_1=5+\frac{7}{4}=\frac{20+7}{4}=\frac{27}{4}

x_1=\frac{27}{4\times 3}=\frac{9}{4}

Hence, the intersection point of two given lines is (\frac{9}{4},\frac{1}{4})

2. Standard form: 8x + y = 9<br> Slope-intercept form:
Effectus [21]

Answer:

y = - 8x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

8x + y = 9 ( subtract 8x from both sides )

y = - 8x + 9 ← in slope- intercept form
