Answer:

Brainliest please

50years is their ages now

Step-by-step explanation:

<h3>use algebra</h3>

onyango= 3a

daughter= let it be a

son= he is 4 times less than his father, 3/4a

8years

8+3a+a+8+3/4a+a

a+8+3/4a+a

7/4+1 = 8/4a+8 + 12y 20= 8/4a = 40years is the father 8 years later, so his present age is 40-8

32y= father now

daughter= 1/3×32=10years

son= 1/4×32= 8yrs

add 32+10+8= 50years

Sea level is considered to be 0 feet. A probe released at sea level dropped at a constant rate for 3.25 minutes, reaching an ele
HACTEHA [7]

d = r * t

d/t = r

-35.75 / 3.25 = r

-11 = r

r = -11 ft / min

d = r*t

d = -11 ft/min * 1 min

d = -11 ft

The probe is 11 feet below sea level after 1 minute

Find an equation of the line described below. Write the equation in slope-intercept form (solved for y), when possible.
SCORPION-xisa [38]

The equation of the line in slope-intercept form would be y = m(x - 1/5) - 8.

<h3>What is slope intercept form a straight line?</h3>

The slope-intercept form of a straight line is used to get the equation of a line. We need to know the slope of the line and the intercept where the line crosses the y-axis in order to use the slope-intercept formula.

One of the most popular ways to represent a line's equation is in the slope-intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope-intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.

Since the slope is undefined in the given question, let us consider it as m.

Therefore, slope=m

Given points are 1/5 and -8, so x₁ = 1/5 and y₁ = -8

We know the formula is, y - y₁ = slope × (x - x₁)

Putting the values of x₁, y₁ and slope in the given formula we get,

y -(-8) = m × (x-1/5)

y = m(x-1/5) - 8

Hence, we get the required equation.
