Recall that the sum of all 3 angles of a triangle is 180. So,
82 + 45 + x = 180>> 127 + x = 180
>> x = 180 - 127
>> x = 53 (final answer)

Determine the x and y intercepts

kakasveta [241]

Answer:
x-intercepts: (2,0), (4,0)
y-intercepts: (0,-8)

Explanation:
To find the x intercept(s), you must compute where y=0. So solve 0= -x^2 + 6x - 8. So, the x intercepts are: (2,0) and (4,0) since the solutions to the mentioned equation are x=2 and x=4. To find the y intercept(s) compute what is y when x=0. In this case, when x=0, y=-8. So the only y intercept is (0,-8).

Graph triangle xyz with vertices x (0,-4) y (4,-1) and z (6,-3) on the coordinate grid

marishachu [46]

How are we supposed to graph this, it's easy the first number in the parenthesis is where it is on the x-axis, the second number in there is where it is at on the y-axis, that should help you so you can graph it yourself.

Which graph shows the solution to the equation below?<br> log3(x+2) = 1

sdas [7]

Refer the attached figure of the graph (Option A) that shows the solution to the given equation

<u>Step-by-step explanation:</u>

The given logarithmic equation is

$\log _{3}(x+2)=1$

The solution to this logarithmic equation is where the graph of

$y=\log _{3}(x+2)$

When comparing above with the given equation, we find that y = 1.

Now, find the 'x' value by using this. So, applying log base 3 rule on right side, we get as below,

$x+2=3^{1}$

x = 3 - 2 = 1

Plot the asymptote and the point (1 , 1). Sketch the log curve using those two reference facts. Hence, concluded the graph in option A as solution to the given equation.

There are 48 students in a school play. The ratio of boys to girls is 5:7. How many boys are in the school play? Explain how you

mr Goodwill [35]

Boys: x
gilrs: y

From the text of the task:

$\left \{ {{\frac{x}{y}=\frac{5}{7}} \atop {x+y=48 \rightarrow x=48-y}} \right.$

Replacing x:

$\frac{48-y}{y}=\frac{5}{7}\\
\\
7(48-y)=5y\\
\\
336-7y=5y\\
\\
12y=336\\
\\
y=\frac{336}{12}=28$

So there are 28 girs and 20 boys
