Answer: y= x-2
Step-by-step explanation:
Perpendicularity entails the slope of line a is -1 divided by the slope of line b
m1= (-1/m2)
From y=Mx +c
We compare with x-4y=7
y=(1/4)x-7/4
Meaning m2= 1/4
m1= -1/(1/4)= -1*4= -4
((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1
x1= 2, y1= -4
((y-(-4))/(x-2))= -4
((y+4)/(x-2))= -4
Cross multiply
y+4= -4(x-2)
y= x-2

Find x, to the nearest hundredth.
Answer: 13.99
Step-by-step explanation:
Using sine rule
((sin 90)/18)= ((sin (180-(90+39)))/x)
((sin 90)/18)=((sin 51)/x)
(1/18)=(0.7771/x)
Cross multiply
x= 0.7771*18
x= 13.99

1. a group of friends went to the movies, and the three guys each bought two tickets (t), a popcorn (p) and two drinks (d) for themselves and their dates.
After distributing, we can represent this situation with the expression. __________________.
Answer:
6t + 3p + 6d
Step-by-step explanation:
Given - A group of friends went to the movies, and the three guys each
bought two tickets (t), a popcorn (p) and two drinks (d) for
themselves and their dates.
To find - After distributing, we can represent this situation with the
expression.
Proof -
As given , three guys each bought two tickets (t), a popcorn (p) and two drinks (d) for themselves and their dates.
Let ticket = t
popcorn = p
drink = d ,
Then,
The expression becomes -
3[2t + p + 2d ] = 6t + 3p + 6d
∴ we get
We can represent this situation with the expression - 6t + 3p + 6d

PLEASE ANSWER THIS ILL GIVE BRAINLIEST
Answer:
(-4, -5)
Step-by-step explanation:
-4x + 2y = 6
-4x + 2(x - 1) = 6
-4x + 2x - 2 = 6
-2x - 2 = 6
-2x - 2 + 2 = 6 + 2
-2x = 8
-2x/-2 = 8/-2
x = -4
------------------------
y = x - 1
y = -4 - 1
y = -5

-4(-4) + 2(-5) = 6

Find the value of (1/5)⁻² + (1/2)⁻³ + (1/4)⁻¹
Answer:
Answer = 37
Step-by-step explanation:
= (5)² + (2)³ + (4)¹
= 25 + 8 + 4
= 37 Answer
Answer: The answer is 37
Step-by-step explanation:
Step 1: Use Negative Power Rule: x^-a=1/x^a. So 1/(1/5)^2+(1/2)^-3+(1/4)^-1
Step 2: Use Division Distributive Property: (x/y)^a=x^a/y^a. So 1/1/5^2+(1/2)^-3+(1/4)^-1
Step 3: Simplify 5^2 to 25. So 1/1/25+(1/2)^-3+(1/4)^-1
Step 4: Use Negative Power Rule: x^-a=1/x^a. So 1/1/25+1/(1/2)^3+(1/4)^-1
Step 5: Use Division Distributive Property: (x/y)^a=x^a/y^a. So 1/1/25+1/1/2^3+(1/4)^-1
Step 6: Simplify 2^3 to 8. So 1/1/25+1/1/8+(1/4)^-1
Step 7: Use Negative Power Rule: x^-a=1/x^a. So 1/1/25+1/1/8+1/1/4
Step 8: Invert and multiply. 25+1/1/8+1/1/4
Step 9: Invert and multiply. 25+8+1/1/4
Step 10: Invert and multiply. 25+8+4
Step 11: Simplify 25+8 to 33. So 33+4
Step 12: Simplify. So the answer is 37

Factor the following polynomial completely. -0.8x2 - 6.4x + 7.2
Answer:
-0.8(x + 9)(x - 1)
Step-by-step explanation:
Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2. Thus,
-0.8x2 - 6.4x + 7.2 = 0.8(-1x^2 - 8x + 9), or, equivalently,
= -0.8(x^2 + 8x - 9), which factors further as follows:
= -0.8(x + 9)(x - 1)

Answer:
32
63
Step-by-step explanation:
m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.
m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.
Step-by-step explanation:
148 + x = 180
x = 180 - 148
x = 32
Find m<CAB basically means find the measure of the angle of A ( m<A )
m<B + m<A + x = 180
85 + m<A + 32 = 180
117 + m<A = 180
m<A = 180 - 117
m< A = 63, so m<CAB = 63
And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.
So m<BCA = 32
What is the area of the figure, use 3.14 for π
Answer: Area of a square is a².
4² = 16
Now find the area of the semicircle.
