(Due in 30 minutes!) Write an equation in slope-intercept form of the line.

Zina [86]

Answer:

y = -1/2x + 2

Step-by-step explanation:

Given the following points on the line:

(0, 2) and (6, -1)

We need to find the slope of the line using the following formula:

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

Let (x1, y1) = (0, 2)

(x2, y2) = (6, -1)

Plug these values into the slope-formula:

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

m = (-1 - 2) / (6 - 0)

m = -3 / 6

m = -1/2

Therefore, the slope of the line is -1/2.

Next, we need to find the y-intercept of the line. The y-intercept is the point on the graph where it crosses the y-axis. It is also the value of y when x = 0. If you look at the graph, you'll see that the line crosses the y-axis at point (0, 2), which happens to be one of the points we used earlier. The y-coordinate of (0, 2) is the y-intercept.

Therefore, the y-intercept (b) = 2.

We can write the linear equation as follows:

y = -1/2x + 2

What should be subtracted from the product of 3/7 and 2/5 to get -4/35?

bonufazy [111]

$\implies {\pink {\boxed {\boxed {\purple {\sf { \: x = \frac{2}{7}}}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

Let $x$ be the unknown number.

As per the question, we have

$\: ( \frac{3}{7} \times \frac{2}{5} ) - x = \frac{ - 4}{35}$

➺ $\: \frac{6}{35} - x = \frac{ - 4}{35}$

➺ $\: - x = \frac{ - 4}{35} - \frac{6}{35}$

➺ $\: - x = \frac{ - 4 - 6}{35}$

➺ $\: - x = \frac{ - 10}{35}$

➺ $\: x = \frac{2}{7}$

Therefore, $\frac{2}{7}$ should be subtracted from the product of $\frac{3}{7}$ and $\frac{2}{5}$ to get $\frac{ - 4}{35}$ .

$\large\mathfrak{{\pmb{\underline{\orange{To\:verify}}{\orange{:}}}}}$

$\: ( \frac{3}{7} \times \frac{2}{5} ) - x = \frac{ - 4}{35}$

➼ $\: ( \frac{6}{35} ) - \frac{2}{7} = \frac{ - 4}{35}$

➼ $\: \frac{6}{35} - \frac{2 \times 5}{7 \times 5} = \frac{ - 4}{35}$

➼ $\: \frac{6 - 10}{35} = \frac{ - 4}{35}$

➼ $\: \frac{ - 4}{35} = \frac{ - 4}{35}$

Q # 7 please solve. the math

aleksandr82 [10.1K]

The first choice is the correct answer
12 in by 22 in by 4 in

the explanation is as shown in the figure
The dimension will be x , 20 - 2x , 30 -2x

the volume= v = x(20-2x)(30-2x) = 4x³ - 100x² + 600x
differentiating with respect to x and equating to zero
dv/dx = 12x² - 200x + 600 = 0
solve for x using calculator
x = 12.7 (unacceptable) or x = 3.92 ≈ 4

∴ The dimension will be 4 , 12 , 22

Find the value of z.

Inessa05 [86]

Answer:

A. 121

Step-by-step explanation:

The sum of the exterior angles is 360°, so you have ...

z + (z +10) + (z -13) = 360

3z -3 = 360 . . . . . collect terms

z -1 = 120 . . . . . . . divide by 3

z = 121 . . . . . . . . . add 1
