Answer:
D. 90°
Step-by-step explanation:
6x + 4x - 1 + 2x + 1 = 180
12x = 180
x = 15
6x = 6 * 15 = 90
Answer: D. 90°
what is the equation of the line?
Answer:
x=3
Step-by-step explanation:
the x axis is going across by 2 and the number in between 2 and 4 is 3 and the line is going through the x axis hence the equation of the line is x=3
Answer:
[tex]x=3[/tex]
Step-by-step explanation:
Normally, linear equations would be written in slope-intercept form, [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis). However, linear equations for horizontal or vertical lines are organized differently.
Here, we're given a vertical line. Vertical lines are written like [tex]x=d[/tex], where [tex]d[/tex] is the x-intercept, or the value of x when the line crosses the x-axis.
From the graph, we can tell that the x-intercept is 3. Therefore, our equation would be [tex]x=3[/tex].

Of the 645 students in the freshman class, 85 are left-handed. About what percentage of the students are left-handed? Round to the nearest tenth.
About % of the freshman class are left-handed.
Answer:
About 13% of the freshman class are left-handed
Step-by-step explanation:
To find the percentage of a whole you need to divide the part by the whole number (85/645 = 0.1316), then you round to the nearest tenth (0.13) and change it into a percentage by moving the decimal point 2 numbers to the right. (13%)

Answer for 2y + 4/x = 10
Answer:
Y = 5 - 2/x
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
You want to isolate x so first, you have to multiply the whole equation by 1/4 so it will look like 1/4(2y+4/x=10). Simplify this to get 1/2y+x=5/2. You want to isolate x, so you have to subtract 1/2 from each side, this will make the equation x=5/2-1/2. Simplify this to get x=4/2 which can also be simplified to x=2. Therefore, the answer is x=2

Solve the simultaneous equations
4x + 5y = 9
4x - 2y = 2
Answer:
x = 1 and y = 1
Step-by-step explanation:
Let's solve your system by substitution.
4x + 5y = 9 ; 4x − 2y = 2
- Solve 4x + 5y = 9 for x:
4x + 5y = 9
4x + 5y + − 5y = 9 + − 5y (Add -5y to both sides)
4x = − 5y + 9
[tex]\frac{4}{x} = \frac{- 5y + 9}{4}[/tex]
[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]
Then Substitute [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex] for x in 4x - 2y = 2
4x − 2y = 2
4([tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]) − 2y = 2
− 7y + 9 = 2 (Simplify both sides of the equation)
− 7y + 9 + − 9 = 2 + − 9 (Add -9 to both sides)
− 7y = − 7
[tex]\frac{- 7y}{- 7} = \frac{- 7}{- 7}[/tex] (Divide both sides by -7)
y = 1
Substitute 1 for y in x = [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]
[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]
[tex]x = \frac{- 5}{4} (1) + \frac{9}{4}[/tex]
x = 1
So, x = 1 and y = 1

The answer is D. Y = 63 + 2 = 65
The given equation is y = x + 2, the height is given as 63. The height is the x value so you would replace x in the equation with 63 and solve for y.

Step-by-step explanation:
What is the equation of the line that passes through the point (-4, 2) and has a
slope of 1/4?
Answer:
y = (1/4)x + 3
Step-by-step explanation:
I have put my answer in slope-intercept form as that is usually the most common. Inputing the slope as "m" into the equation "y=mx+b" and substituting the x and y coordinates given to find b gives the equation "2=(1/4)(-4)+b" By solving this we get "b=3" to finish the equation.
Answer:
y=1/4x+3
Step-by-step explanation:
y-2=1/4(x-(-4))
y-2=1/4(x+4)
y-2=1/4x+1
y=1/4x+1+2
y=1/4x+3
Can someone please help me with math
Answer:
B
Step-by-step explanation:
they want us to find the equation in slope intercept form
which is y= mx + b
where m = slope and b = y intercept
the slope is change in y over change in x
as y goes up 1 x goes up 1 so the slope is 1 or m=1
the y intercept is at point (0,1)
so the y intercept is 1
now we add it all together and get that the equation Is
y=x+1

What is the area of the shaded quadrilateral? (see attachment)
Answer:
B. 36 [tex]cm^{2}[/tex]
Step-by-step explanation:
The shaded quadrilateral has a shape of a trapezium.
Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the side length parallel to the base, b is the base and h is the height.
The height of the figure = 11 - (4 + 1)
= 11 - 5
= 6
The height of the figure is 6 cm.
The length of its base = 11 - (1 + 2)
= 11 - 3
= 8
The length of its base is 8 cm.
The length of the side parallel to base = 11 - (4 + 3)
= 11 - 7
= 4
The parallel side length to base is 4 cm.
Area of quadrilateral = [tex]\frac{1}{2}[/tex](a + b)h
= [tex]\frac{1}{2}[/tex](4 + 8)6
= 12 x 3
= 36
Area of quadrilateral = 36 [tex]cm^{2}[/tex]

Ed's birthday is less than 16 days
away. Ann writes the inequality
d< 16, where d equals the number
of days, to represent this. Is Ann
correct? Explain.
Answer: Yes
Step-by-step explanation:
From the question, we are informed that Ed's birthday is less than 16 days
away and that Ann writes the inequality
d< 16, where d equals the number
of days, to represent this.
The inequality d < 16 is correct as it explains that the number of days left is less than 16.
Answer:
Ann is correct because d is less than 16.
Step-by-step explanation:
Ed's Birthday is *less than 16* days away so d<16
