what’s the answer to this question ?
Answer:
C
Step-by-step explanation:
Line pases through (6, 0) and (0, -6)
Slope = (0 - (-6))/(6 - 0) = 6/6 = 1
so y = 1*(x - 6) = x - 6
or x - y = 6
or 4x - 4y = 24
That is C

Answer:
x = 9
Step-by-step explanation:
To Find the value of x and all angles :
We know that,
Sum of all angles of a triangle = 180°.⠀
Therefore,
[tex]{ \longrightarrow \sf \qquad \angle1 + \angle2 + \angle3= 180 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \sf \qquad (13x + 2) {}^{ \circ} + (5x - 7){}^{ \circ}+ (3x - 4) {}^{ \circ} = 180 {}^{ \circ} }[/tex]
⠀
Adding like terms we get :
[tex]{ \longrightarrow \sf \qquad (13x +5x + 3x) + { \bigg[2 + ( - 7) + ( - 4) \bigg]}^{ \circ}= 180 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \sf \qquad 21x+ ( - 9) {}^{ \circ}= 180 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \sf \qquad 21x = 180 {}^{ \circ} } \sf+ \: 9 {}^{ \circ}[/tex]
[tex]{ \longrightarrow \sf \qquad 21x = 189 {}^{ \circ}}[/tex]
[tex]{ \longrightarrow \sf \qquad x = \dfrac{189 {}^{ \circ}}{21} }[/tex]
[tex]{ \longrightarrow { \pmb{\bf \qquad x = 9 {}^{ \circ}}}}[/tex]
⠀
Therefore,
[tex] \longrightarrow \: \sf \qquad \angle1 = (13x + 2) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle1 = (13.9 + 2) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle1 = (117 + 2) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \bf \qquad \angle1 = 119 {}^{ \circ}[/tex]
⠀
[tex]\longrightarrow \: \sf \qquad \angle2 = (5x - 7) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle2 = (5.9 - 7) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle2 = (45 - 7) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \bf \qquad \angle2 = 38 {}^{ \circ}[/tex]
⠀
[tex]\longrightarrow \: \sf \qquad \angle3 = (3x - 4) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle3 = (3.9 - 4) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle3 = (27 - 4) {}^{ \circ}[/tex]

A line passes through the point (−4,5) and has a slope of −6.
Write an equation in slope-intercept form for this line.
Answer:
y = -6x - 19
Step-by-step explanation:
We can use y = m x + c to find the equation of the line.
Here,
m ⇒ slope
c ⇒ y - intercept
They have already given the slope of the line.
m = -6
And now we have to find the y - intercept using the given coordinates.
( -4 , 5 ) ⇒ ( x , y )
Let us find now.
y = m x + c
5 = -6 × -4 + c
5 = 24 + c
5 - 24 = c
-19 = c
Now let us write the equation of the line.
y = m x + c
y = -6x - 19

Answer:
220 square inches.
Step-by-step explanation:
You have to find the area of each fact on the rectangular prism and add them all up. There are two faces in the prism with each pair of side lengths, like two faces with side lengths of 4x5, two with 5x10, etc.
4x5 = 20 20x2 = 40
4x10 = 40 40x2 = 80
5x10 = 50 50x2 = 100
100 + 80 + 40 = 220 square inches
Answer:
B. 220 in ^2
To find the surface area, we have to find the area of each face and add them all together.
Let's get started.
Face one:
Let's start with the one facing us.
The width is 4
The length is 10
4 x 10 = 40
Since there is an identical face on the opposite side, we need two of those.
40 x 2 = 80
Now let's do the face facing to the right.
The length is 10
The width is 5
5 x 10 = 50
Since there is an identical face on the opposite side, we need two of those.
50 x 2 = 100
Now the one on the top
The length is 5
The width is 4
5 x 4 = 20
Since there is an identical face on the opposite side, we need two of those.
20 x 2 = 40
80 + 100 + 40 = 220

What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
Perpendicular slope: -7x
Parallel slope: 1/7x
Step-by-step explanation:
Rewrite this into slope-intercept form. So y=1/7x -1/7
Slope of a perpendicular line is the reciprocal of the original slope. So perpendicular line would be y=(-7)x-1/7. Slope in the perpendicular is -7. A parallel line will have the same slope,so basically y=1/7x-1 .
It doesn't matter what the y-int would be since a perpendicular/parallel slope only depends on the slope itself.
Answer:
[tex]\displaystyle \parallel\:\frac{1}{7} \\ \perp\:-7[/tex]
Step-by-step explanation:
[tex]\displaystyle x - 7y = 1 \hookrightarrow \frac{-7y}{-7} = \frac{-x + 1}{-7} \\ \\ \boxed{y = \frac{1}{7}x - \frac{1}{7}}[/tex]
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so ⅐ remains as is. Perpendicular equations however, have OPPOCITE MULTIPLICATIVE INVERCE RATE OF CHANGES, so ⅐ becomes −7.

Find the measure of the missing angle 17
Answer:
<A =73
Step-by-step explanation:
The sum of the angles of a triangle are 180
<C is 90
<B is 17
We need to find <A
<A + < B + <C = 180
<A + 17+90 = 180
<A + 107 =180
<A = 180-107
<A =73

The length of the hypotenuse of a right triangle is 50 inches. Determine the length of the legs if each leg is the same length.
Answer:
25√2 ≈ 35.36 inches
Step-by-step explanation:
The Pythagorean theorem can be used to find the leg length for the given conditions. It tells you the relation between legs a, b, and hypotenuse c is ...
c² = a² +b²
If a=b, and c=50, this becomes ...
50² = a² +a²
1250 = a² . . . . divide by 2
25√2 = a . . . . take the square root
The length of each leg is 25√2 ≈ 35.36 inches.
Emma has a coupon for $5.25 off a frame that normally costs $15.00. What percent discount did she receive on the frame? Show your work in arriving at your answer.
Emma has received a 35 percent discount on the frame
What is a discount?A discount is a reduction in price of an item usually for promotion or marketing purposes.
A discount could be in the form of a percentage off the price of the item or a fixed amount(say $7) off the price of the item
In the case of Emma, he got a fixed amount off the price which we converted to percentage to determine the amount off. This is calculated thus:
discount price/price of item ×100/1
5.25/15×100/1= 0.35(35%)
If a percentage is used, a variable( can change)amount in the form of a discount is possible otherwise not.
