Answer:

z=40 degrees

Step-by-step explanation:

a triangle is 180 degrees

<ACB=50 (180-130=50)

50+90=140

180-140=40

Answer:

40 degrees

Step-by-step explanation:

so in order to find this we first off know that every triangle's inside angles are equal to 180 degrees total.

so if we take that <A is equal to 90 degrees

then we see that the outside of <C is equal to 130 and line BCD is a confirmed straight line

then each line is equal to 180 degrees so we subtract 130 from 180 in order to find the inside angle of C so that would equal 50

so now that we know <A=90

and <C=50

then we add those two together and that equals 140 degrees

and so there is only one more angle which is <Z

so we subtract 140 from the total amount of 180 degrees in the triangle

leaving us with <Z=40 degrees

Answer:

A. Proportional by $30

B. 3 represents the hours he works

    90 represents the money he earned

C. $300

D. I don know, sorry

Step-by-step explanation:

The relationship is linear, the point (3, 90) represents in 3 hours he earns 90 dollars, in 10 hours, he earns 300 dollars, and the linear equation is y = 30x.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

This graph shows the relationship between x, the number of hours Mr. David works, and y, the number of dollars he earns.

A. Based on the graph, the relationship between x and y proportional is a linear relationship.

B. The point (3,90) represents in 3 hours he earns 90 dollars.

D. The linear equation will be

[tex]\begin{aligned} \rm y - 30 &= \rm \dfrac{90-30}{3-1} (x - 1)\\\\\rm y - 30 &= \rm 30x - 30\\\\\rm y &= \rm 30x \end{aligned}[/tex]

C. Based on the graph, the amount of money in dollars will Mr. David earn if he works 10 hours will be

y = 30x

y = 30 × 10

y = $300

Answer:

[tex]y-9 = \frac{15}{7} (x-8)[/tex]

Step-by-step explanation:

Point-slope form is represented by [tex]y-y_1 = m (x-x_1)[/tex]. To write an equation with it, we need the slope of the line and a point the line crosses through. We already have at least one point the line crosses through, so let's figure out the slope.

To find the slope, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line crosses, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line crosses. So, using the x and y values of (1, -6) and (8, 9), substitute them into the formula and solve:

[tex]\frac{(9)-(-6)}{(8)-(1)} \\= \frac{9+6}{8-1} \\= \frac{15}{7}[/tex]

Thus, the slope is [tex]\frac{15}{7}[/tex].

2) Now, using the point-slope form of  [tex]y-y_1 = m (x-x_1)[/tex],  substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values in order to write an equation in point-slope form. The [tex]m[/tex] represents the slope, so substitute [tex]\frac{15}{7}[/tex] in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line. So, choose any one of the points given - either one is fine - and substitute its x and y values for [tex]x_1[/tex] and [tex]y_1[/tex]. (I chose (8,9)). This gives the following equation and answer:

[tex]y-9 = \frac{15}{7} (x-8)[/tex]

Answer:

I think adjacent angles are the vertical angles but supplementary angles are 2 angles that combine to equal 180 degrees and complementary angles are 2 angles that add up to 90 degrees so the right angle with a ray splitting it is a complementary angle.

Answer:

there would be 24 grams of copper.

Answer:

21

Step-by-step explanation:

straight line = 180 degrees ( H,D,R)

180 = 7x - 3 + 2x  - 6    

180 = 7x + 2x - 3 - 6     (group the same type number together)

180 = 9x -9           (simplify the numbers)

189 = 9x    (+9)

21 = x    (divide by 9)

Step-by-step explanation:

Answer:

(2, 4 )

Step-by-step explanation:

Given the 2 equations

y = 2x → (1)

x = - y + 6 → (2)

Substitute x = - y + 6 into (1)

y = 2(- y + 6) ← distribute

y = - 2y + 12 ( add 2y to both sides )

3y = 12 ( divide both sides by 3 )

y = 4

Substitute y = 4 into (2) for corresponding value of x

x = - 4 + 6 = 2

solution is (2, 4 )
