Answer:
The value of x is 3
Step-by-step explanation:
∵ Quadrilateral ABCD is congruent to quadrilateral JKLM
∴ AB = JK and BC = KL
∴ CD = LM and AD = JM
∵ BC = 8x + 7
∵ KL = 31
∵ BC = KL
→ Equate their right sides
∴ 8x + 7 = 31
→ Subtract 7 from both sides
∵ 8x + 7 - 7 = 31 - 7
∴ 8x = 24
→ Divide both sides by 8 to find x
∴ [tex]\frac{8x}{8}[/tex] = [tex]\frac{24}{8}[/tex]
∴ x = 3
∴ The value of x is 3

(2, 4) and (5, 1)
(-7, 8) and (-7,0)
(6,-3) and (-4,-3)
(3,5) and (-1,2)
Answer:
2.) undefined slope 3.) zero slope (i'm not sure what 1 and 4 are, sorry!)
Step-by-step explanation:
undefined slope has the same x-coordinate and the denominator becomes 0. it also is a vertical line. for a zero slope, it has the same y-coordinate and the numerator is 0. this is a horizontal line. *this is my first response so if i am wrong, that is embarrassing*
Alana runs 4 laps around the track in 10 minutes. If Alana runs 17 laps at the same rate how long does it take her
Answer:
42 minues 5 seconds to do 17 laps.
Step-by-step explanation:
it takes her 2 minuetes and 50 seconds to do 1 lap if you multiply 2.5x17=
42 munites and 5 secondesto do 17 laps
Answer:
It would take 42.5 min
Step-by-step explanation:
4/10 = 2.5(unit rate for every lap it takes 2.5 min)
17 x 2.5 = 42.5

A function graph of a line with two points (-3,-2) and (-1,2) with an x axis of negative five to five and a y axis of negative five to five
9514 1404 393
Answer:
y = 2x + 4
Step-by-step explanation:
You have the graph, so you can read the slope and y-intercept from it. The line goes up 2 units for each unit to the right, so the slope is ...
slope = rise/run = 2/1 = 2
The y-intercept is where the graph crosses the y-axis, at y=4.
The slope-intercept form of the equation for a line is ...
y = mx + b
where m is the slope (2) and b is the y-intercept (4). Your equation is ...
y = 2x +4

B. 2/3, 1/4, 29%, 0.06
C. 0.06, 1/4, 29%, 2/3
D. 1/4, 2/3, 0.06, 29%
Answer:

Step-by-step explanation:
2/3 converts to 0.66666667, 66.67%
1/4 converts to 0.25 , 25%
0.06 converts to 6%
So the order from least to greatest would be 0.06 , 1/4 , 29% , 2/3

Answer:The slope is 6/7
Step-by-step explanation:
when finding the slope you will need to move the 6x to the other side of the equation by subtracting which gives you 7y=14-6x and all that is left is to divide by 7 which gives y=14-6/7y
Answer:
6x - 7y = 14
⇔ 6x - 14 = 7y
⇔ 6/7.x - 2 = y
=> the slope is 6/7

How many factors of 100 are also multiples of 5?
Let us write the factors of 100. A factor of 100 can only be a multiple of five if it is divisible by five.
Divisibility rule of 5: A number can only be divisible by five if the ones digit of the number is a five or 0.Factors of 100 ⇒ numbers divisible by 100 ⇒ 1, 2, 4, 5, 10, 20, 25, 50, 100
When checking each factor of 100;
1 is not a multiple of 5 ⇔ not divisible by 5.2 is not a multiple of 5 ⇔ not divisible by 5.4 is not a multiple of 5 ⇔ not divisible by 5.5 is a multiple of 5 ⇔ divisible by 5.10 is a multiple of 5 ⇔ divisible by 5.20 is a multiple of 5 ⇔ divisible by 5.50 is a multiple of 5 ⇔ divisible by 5.100 is a multiple of 5 ⇔ divisible by 5.⇒ Five factors are multiples of 5.
Therefore, five factors of 100 are multiples of 5.

carla, bev, and ashley took their unit 2 math test. carla made an 80 and bev made a 75. what was ashleys score on the test if their average was 78.
Answer:
Ashley = 79
Step-by-step explanation:
[tex]Average=\frac{Carla+Bev+Ashley}{3}=78\\\\\frac{80+75+Ashley}{3}= 78 \\\\\frac{155+Ashley}{3}=78\\\\\frac{155+Ashley}{3}*\frac{3}{1} =78*3\\\\155+Ashley=234\\[/tex]
Subtract 155 from both sides;
Ashley = 79
which line is parallel to y=8x+11?
Answer:
Any line with a slope of 8 is parallel to y = 8x + 11. Some examples are:
y = 8x + 5
y = 8x + 1000
y = 8x +9
It doesn't matter what the y-intercept as long as the slope remains the same for a parallel line.
Answer:
Like the other person said, any line that has the same slope (8) will be parallel.

help I will give brainliest
please show work
Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)
