The graph of a linear function “f” passes through the point (1, 3) and has a slope of 3.
What is the y-intercept?

Answers

Answer 1

Answer:

0

Step-by-step explanation:

Using slope intercept as ref (y=mx+b)

plug in the x and y x=1 and y=3 and the slope m=3

3=3(1)+b

solve for b

3=3+b

b=0

Find the height of the object next to the triangle using the similarity of the triangle.​

Answers

Answer: If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

Find the solution to the system of the equations shown below: y = -4x + 11
y=1/2x+2​

Answers

Hello!

[tex]\large\boxed{x = 2}[/tex]

Set the two equations equal to each other to solve:

y = -4x + 11

y = 1/2x + 2

-4x + 11 = 1/2x + 2

Add 4x to both sides:

-4x + 4x + 11 = 1/2x + 2 **Convert 4x into 8/2x***

11 = 9/2x + 2

Subtract 2 from both sides:

11 - 2 = 9/2x + 2 - 2

9 = 9/2x

Divide both sides by 9/2:

9 * (2/9) = 9/2x * (2/9)

x = 2.

Given that f(x) = x? 10x + 16 and g(x) = x – 8, find f(x) · g(x) and
express the result in standard form.

Answers

Answer:

=x^3+2x^2-72x-64

Step-by-step explanation:

(x^2+10x+8)*(x-8)=

=x^3+2x^2-72x-64

Standard form of given expression is x³ + 2x² - 64x - 128

Given:

f(x) = x² + 10x + 16

g(x) = x – 8

Find:

f(x) · g(x)

Computation:

f(x) · g(x)

(x² + 10x + 16)(x – 8)

(x²)(x) + (10x)(x) + (16)(x) + (x²)(-8) + (10x)(-8) + (16)(-8)

x³ + 10x² + 16x - 8x² - 80x - 128

x³ + 2x² - 64x - 128

Answers

Answer: Do mind that I don’t completely trust that I am right, but I ask that you have faith in me.

So if I’m thinking correctly we subtract 180 from 217 which gives us 37. We then add that to 104 and subtract the sum from 180 which gives us b. So,

180-104+37
180-141=39

So b should equal 39 degrees, to check we add all the respective angles up,

104+39+37=180

The swimming team has 84 members. The number of boys on the team is six more than twice the number of girls. How many boys and girls are on the team?

Answers

Answer:

the number of boys and girls on a team is 58 and 26 respectively

Step-by-step explanation:

Given that

Total members in swimming team is 84

Let us assume the number of girls be x

so, the number of boys would be

y = 2x + 6

Now the equation is

x + y = 84

x + 2x + 6 = 84

3x = 78

x = 26

And, y = 2 × 26 + 6

= 52 + 6

= 58

Hence, the number of boys and girls on a team is 58 and 26 respectively
