Answer:

1) Slope: 3; y-intercept: -7

2) Slope: 2/3; y-intercept: 1

Step-by-step explanation:

y = mx + b; m is slope and b is y-intercept

1. y = 3x - 7

The equation is already in slope-intercept form, so you can find the slope and intercept.

Slope: 3

y-intercept: -7

2. y - 1 = 2/3x

For this one, you have to convert this into slope-intercept form (solving for y)

y - 1 = 2/3x

Add 1 to both sides

y - 1 + 1 = 2/3x + 1

y = 2/3x + 1

Now that the equation is in slope-intercept form, you can get the slope and y-intercept.

Slope: 2/3

y-intercept: 1

Answer:

Angle 13 equal 90 and Angle 12 equal 45

Step-by-step explanation:

This is a square so all of the corner angles and the diagonals angles measure 90 degrees. A square also forms 4 congruent isoceles triangles or technically 45-45-90 triangles. So that means the following angles measure 45 degrees since they share a point

Angle 5,6,7,8,9,10,11,12. So the measure of 12 is 90 degrees.

To find the measure of 13, in a square diagonals bisect each other and form perpendicular lines so that means every angle in the middle of the square measure 90 degrees.

Using that

Angle 13,15,16 and R measure 90 degrees so Angle 13 equal 90.

T can be equal to 1 1/10 or 1.1 or 11/10

Step-by-step explanation:

10t=11

So divide by 10 on both sides.

t=11/10 which can be simplified to t=1 1/10 or t=1.1

The system of equations are solved and the cost of adult ticket and child tickets are $ 6 and $ 4 respectively

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the adult tickets be a

Let the child tickets be c

Group A buys 3 adult tickets and 2 child tickets and pays a total of $26

So , 3a + 2c = 26   be equation (1)

And , Group B buys 5 adult tickets and 3 child tickets and pays $42

So , 5a + 3c = 42   be equation (2)

On simplifying , we get

Multiply equation (1) by 5 and equation (2) by 3 , we get

15a + 10c = 130   be equation (3)

15a + 9c = 126   be equation (4)

Subtracting equation (4) from equation (3) , we get

c = $ 4

Therefore , the cost of child ticket is $ 4

Substituting the value of c in equation (1) , we get

3a + 2 ( 4 ) = 26

3a + 8 = 26

Subtracting 8 on both sides , we get

3a = 18

Divide by 3 on both sides , we get

a = $ 6

Therefore , the cost of adult ticket is $ 6

Hence , the system of equations are solved

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation of the line is y = -0.5x + 5

Option C is the correct option.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the line y = mx + c.

The line passes through (4, 3) and (6, 2).

This means,

We can find the slope using the coordinates (4, 3) and (6, 2).

Slope = m

m = (2 - 3) / (6 - 4)

m = -1 / 2

Now,

For the y-intercept.

Take any point.

(4, 3) = (x, y)

y = mx + c

3 = (-1/2)4 + c

3 = -2 + c

3 + 2 = c

c = 5

Now,

m = (-1/2) = -0.5

c = 5

The equation of the line is y = -0.5x + 5

Thus,

The equation of the line is y = -0.5x + 5

Option C is the correct option.

Step-by-step explanation:

Answer:

$40.25

Step-by-step explanation:

15% = 0.15, so multiply 35 * 0.15 = 5.25 to get the tip.

Since the answer is asking for both the tip and the cost, add 35 + 5.25, which gives the answer $40.25

[tex]\% Percent = 75 \%[/tex]

Step-by-step explanation:

Given

[tex]Painters = 32[/tex]

[tex]Interior\ Painters = 24[/tex]

Required

Determine the percentage of the interior painters

This percentage is calculated as:

[tex]\% Percent = \frac{Interior\ Painters}{Painters} * 100\%[/tex]

This gives:

[tex]\% Percent = \frac{24}{32} * 100\%[/tex]

[tex]\% Percent = \frac{24* 100\%}{32}[/tex]

[tex]\% Percent = \frac{2400\%}{32}[/tex]

[tex]\% Percent = 75 \%[/tex]

75% are painting the interiors
