Step-by-step explanation:

Step 1: Define

-98 = 7t

Step 2: Solve for t

Divide 7 on both sides: -14 = t

Rewrite: t = -14

Step 3: Check

Plug in t into the original equation to verify it's a solution.

Substitute in t: -98 = 7(-14)

Multiply: -98 = -98

Here we see that -98 is equal to -98.

∴ t = -14 is the solution to the equation.

Answer:

slope = - 2, point on line = (- 1, 3 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 2(x + 1) ← is in point- slope form

with slope m = - 2 and (a, b ) = (- 1, 3 )

The slope of equation y−3=−2(x+1) is -2.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y−3=−2(x+1)

Using Slope- Intercept form

y= mx + b

So, the slope for the equation is -2.

Hence, the slope is -2.

Answer:

6 miles

Step-by-step explanation:

At a speed of 8 2/5 miles per hour, you can run a distance of 6 miles

Speed = distance / time taken

8 2/5 = x ÷ 5/7

42/5 = x ÷ 5/7

cross product

42/5 × 5/7 = x

x = (42×5) / (5×7)

= 210/35

= 6 miles

Therefore, you can run a distance of 6 miles at a speed of 8 2/5 miles per hour

Answer:

C

Step-by-step explanation:

So this one is pretty much like the last one

the distance on the x values is 6 and the distance on the y values is 4

1/6 of 6 is 1 and 1/6 of 4 is .66

We subtract the coordinates from R

4-1 is 3

2 -.66 =1.33

The 1/6 point is at (-3,1.33)

Answer:

#4,   x-1/(x^2+3x+2)

Step-by-step explanation:

x/(x^2+3x+2) - 1/((x+2)(x+1))

Convert the 1/((x+2)(x+1)) to 1/(x^2+3x+2)

now you have a common denominator to subtract

x/(x^2+3x+2) - 1/(x^2+3x+2)

results x-1/(x^2+3x+2)

Step-by-step explanation:

Answer:

d) 20

Step-by-step explanation:

To find possible side lengths use the triangle inequality theorem. The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. So for the measurements 6, 11, 20 to make a triangle 6+11 must equal at least 20, which isn't true. Therefore, 20 cannot be a measurement for this triangle.

Answer:

6cm

Step-by-step explanation:

The formula for the surface area of a sphere = 4πr²

From the Question, we are given:

The surface area of a sphere = 144pi square centimeters = 144π cm²

The length of the radius of the sphere, in centimeters is calculated by:

4πr² = 144π

Divide both sides by 4π

4πr²/4π = 144π/4π

r² = 36

Square root both sides

√r² = √36

r = 6cm

Therefore, the length of the radius of the sphere, in centimeters is 6 centimeters.

Answer:

The volume is;

3951.8 cm^3

Step-by-step explanation:

As we can see, the sphere diameter is 19 cm

Radius is half of this which is 19/2 = 9.5 cm

Putting this in the area , we have

4/3 * 3.142 * 9.5^3 = 3951.8

cm^3

===================================================

Work Shown:

2x+3y = 18

3y = 18-2x ..... subtract 2x from both sides

3y = -2x+18

y = (-2x+18)/3 .... divide both sides by 3

y = (-2x)/3 + 18/3

y = (-2/3)x + 6

-----------

As a quick shortcut, anything in the form Ax+By = C will convert to y = (-A/B)x+(C/B) when you solve for y.

The slope is -A/B and the y intercept is C/B
