Find the gradient and y intercept of 3x+4y=5

noname [10]

Answer:

gradient = - $\frac{3}{4}$ , y- intercept = $\frac{5}{4}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + 4y = 5 ( subtract 3x from both sides )

4y = - 3x + 5 ( divide terms by 4 )

y = - $\frac{3}{4}$ x + $\frac{5}{4}$ ← in slope- intercept form

with slope m = - $\frac{3}{4}$ and y- intercept c = $\frac{5}{4}$

4. Solve the following inequality: 3y-1 less than 3

mylen [45]

3y - 1 < 3

Isolate the y. Treat the less than or equal like an equal sign.

Do the opposite of PEMDAS. First, add 1 to both sides

3y - 1 (+1) < 3 (+1)

3y < 4

Next, divide 3 from both sides

3y/3 < 4/3

y < 4/3

y < 4/3 is your answer

hope this helps

Mary, who has type O blood, is expecting a child with her husband, who has type B blood. Mary's husband's father has type A bloo

PilotLPTM [1.2K]

Answer:

50% is the answer.

Step-by-step explanation:

All three persons have different blood groups.

Mary has O blood type.

Her husband has B blood type.

Her father in law has A blood type.

As everyone has different blood groups and the child's group depends on parents blood groups so we have 2 options left.

Hence, the probability that the child will have type O blood is = $\frac{1}{2}$ =50%
