The slope between (8, 10) and (14, -5) will be:
[tex]m=-\frac{5}{2}[/tex]Step-by-step explanation:
Given the points
(8, 10)(14, -5)Finding the slope between (8, 10) and (14, -5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(8,\:10\right),\:\left(x_2,\:y_2\right)=\left(14,\:-5\right)[/tex]
[tex]m=\frac{-5-10}{14-8}[/tex]
[tex]m=-\frac{5}{2}[/tex]
Therefore, the slope between (8, 10) and (14, -5) will be:
[tex]m=-\frac{5}{2}[/tex]What is the slope of a line perpendicular to the line y = −14x – 1?
Answer:
m = ¹/₁₄Step-by-step explanation:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1
{Two lines are perpendicular if the product of theirs slopes is equal -1}
y = -14x - 1 ⇒ m₁ = -14
-14×m₂ = -1 ⇒ m₂ = ¹/₁₄
So, the slope of a line perpendicular to the line y = -14x - 1 is m = ¹/₁₄

WILL MARK BRAINLIEST TO THE BEST ANSWERS. The interior angles of a pentagon measure x°, (2x)°, (2.5x)° , (x + 10)° , and (2x + 20)°. Determine the value of x. PLEASE SHOW ALL SOLUTIONS NESSICARY. THANK YOU.......
Answer:
x=60
Step-by-step explanation:
The sum of interior angles of a regular Pentagon is 540°
x+2x+2.5x+x+10+2x+20=540
8.5x=540-30
8.5x=510
x=510/8.5=60
Answer:
x = 60°Step-by-step explanation:
Sum of interior angles of a regular polygon is:
180°(n-2)Pentagon has 5 sides, so sum of angles is:
180°(5-2) = 180°*3 = 540°For the given pentagon we have sum of angle measures as below, and solving for x:
x + 2x + 2.5x + (x +10) + (2x + 20) = 540°8.5x + 30° = 540°8.5x = 510°x = 510°/8.5x = 60°write the slope-intercept form of the equation of the line.
Answer: y=x+2
Step-by-step explanation:
ok, so the points from the graph in the picture that i used were (0, 2) and (-2, 0).
(0, 2) is the y-intercept, which will replace b.
y=mx+2
the slope of the line is 1.
y=1x+2
y=x+2

The required percentage that Cortney got correct on the test will be; 85.33%.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
We have been given that Cortney got 64 out of 75 correct on a test.
We Need to determine the best estimate of the percentage Courtney got correct.
Here,
The Total question = 75
The correct question = 64
Then Percentage = 64 / 75 × 100
Percentage = 85.33%
Thus, the required percentage that Cortney got correct on the test will be; 85.33%.

XY zand ABC are similar. If angle X is 32 degrees and angle Y is 84
degrees, find the measure of angle C.
Answer:
B
Step-by-step explanation:
A triangle always has a degree total of 180. x+y=116 180-116=64 therefore the last angle, angle c, must be 64 degrees.
Answer: B. 64 degrees
Step-by-step explanation:
∠C = 180° - (∠X + ∠Y)
∠C = 180° - (32° + 84°) = 180° - 116° = 64°

Identify the GCF that was factored out of the polynomial -7t2 -42t -49
Answer:
-7
Step-by-step explanation:
You could take out a factor of -7.
-7t²/-7 = t²
-42t/-7 = 6t
-49/-7 = 7
So the GCF is -7.
The expression 17x is equivalent to the expression x 7.

20% of 260 students at hill middle school ride a bus to school. how many students ride a bus to school?
Answer:
52 students ride a bus to school
Step-by-step explanation:
Step 1: Our output value is 260.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above $260 = 100%.
Step 4: Similarly, x = 20%.
Step 5: This results in a pair of simple equations:
260 = 100%(1).
x = 20%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
[tex]\frac{260}{x}[/tex] = [tex]\frac{100}{20}[/tex]%
Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{260}[/tex] = [tex]\frac{20}{100}[/tex]
⇒x=52$
Therefore, 20% of 260 is 52.
Hope this helps! :)
BRAINLIEST PLEASEEE
The number of students who ride a bus is 52.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of students = 260
The number of students who ride a bus.
= 20% of 260
= 1/5 x 260
= 52
Thus,
The number of students who ride a bus is 52.

Solve the System by Substitution:
y = x-2
x + y = 4
Answer:
x=3
y=1
Step-by-step explanation:
We know that y is basically two less than x, so we can plug that into the second equation:
x+ (x-2) = 4
We can now simplify:
2x-2=4
2x=6
x=3
After finding x we can now find y with any equation (both work):
y= 3-2
y=1

Answer:
x = 3, y = 1Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer: -1m²+81
Step-by-step explanation:
correct standard form means that the terms are ordered from biggest exponent to lowest exponent.The leading coefficient is the coefficient
of the first term in a polynomial in standard form.
FoR example, (9+ m) (-m+9) = *(m+9) (-m+9) *m(-m+9) +9 (-m+9)* -1.mm+9m +9(-m+9) * -1m² +9m +9(-m+9) *-1m²+9m- 9m +81
