Answer:

Step-by-step explanation:

The y intercept of any equation that is a function is the y value taken on when x = 0

So in this case it is y = - 3 because 4*0 = 0. All that is left for y is y = -3.

The point of interception is (0.-3). The way to confirm many answers is to graph the point.

Answer:

y-intercept of y=4x-3 is -3

Step-by-step explanation:

The given equation is:

y = 4x -3

The equation is in slope-intercept form.

The standard equation of slope-intercept form is:

y = mx + b

where m is the slope and b is the y-intercept

So, comparing the given equation with the standard equation the y-intercept is -3

y-intercept of y=4x-3 is -3

Given: Angle 2 is 65 degrees. What is the angle measurement of Angle 4. Explain the angle relationship used and show your work.

lesya [120]

Answer:

$\angle 4 = 115^{\circ}$

$\angle 3 = 65^{\circ}$

$\angle 7 = 65^{\circ}$

Step-by-step explanation:

Given

$\angle 2 = 65^{\circ}$

See attachment

Solving (a): $\angle 4$

To solve for $\angle 4$ , we make use of:

$\angle 2 +\angle 4 = 180^{\circ}$

The relationship between both angles is that they are complementary angles

Make $\angle 4$ the subject

$\angle 4 = 180^{\circ} - \angle 2$

Substitute $65^{\circ}$ for $\angle 2$

$\angle 4 = 180^{\circ} - 65^{\circ}$

$\angle 4 = 115^{\circ}$

Solving (b): $\angle 3$

To solve for $\angle 3$ , we make use of:

$\angle 3 =\angle 2$

The relationship between both angles is that they are complementary angles

$\angle 3 = 65^{\circ}$

Solving (c): $\angle 7$

To solve for $\angle 7$ , we make use of:

$\angle 7 = \angle 3$

The relationship between both angles is that they are alternate exterior angles.

So:

$\angle 7 = 65^{\circ}$

If sin theta = 4/5 then sec theta is?

Softa [21]

Answer: 53.13
Explanation of answer: since theta is the unknown, then you must use the inverse of sin. (Which is sin with -1 subscript) I used a calculator and used inverse of sin and put 4/5 in parenthesis

Donnie's dog had a litter of puppies. He notices that 2 are brown, 1 is white, and 3 are spotted. What is the ratio of total pup

Levart [38]

Answer:

The ratio of total puppies to brown puppies is 3 for 1. For every 3 puppies there is 1 brown puppie.

Step-by-step explanation:

In order to find the ratio between the total puppies to brown puppies we need to take the total amount of puppies , that is, the sum of all the puppies and divide it by the number of brown puppies. So we have:

ratio = total amount of puppies/brown puppies

ratio = (3+2+1)/(2) = 6/2 = 3/1

The ratio is for every three puppies we have one brown puppie.
