Use the table to work out the values of a , b , c , and d .
Answer:
a = - 1, b = - 3, c = - 5, d = - 6
Step-by-step explanation:
Substitute the appropriate values of x into the equation and evaluate
x = - 3 : y = - (- 3) - 4 = 3 - 4 = - 1 → a
x = - 1 : y = - (- 1) - 4 = 1 - 4 = - 3 → b
x = 1 : y = - 1 - 4 = - 5 → c
x = 2 : y = - 2 - 4 = - 6 → d
Answer:
Step-by-step explanation:
[tex]f(x) = -x-4\\f(-3)=-1\\f(-1)=-3\\f(1)=-5\\f(2)=-6[/tex]

Find the equation of a line that has the same slope as y = 5 - 9x and the same y-intercept as y=-8x - 10.
Answer:
y=-9x-10
Step-by-step explanation:
First, start by putting the first equation into slope intercept form:
y=-9x+5
We know that in the standard slope intercept formula (y=mx+b), m is the slope and b is the y intercept. Thus, line with the same slope as the one above would have a slope of -9.
To have the same y intercept as y=-8x-10, the y intercept would have to be -10.
Therefore, the formula would be y=-9x-10
Answer:
y = - 6/5x + 8/9
Step-by-step explanation:
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut point with the y axis
We have the following equations:
Equation 1:
By definition, if two lines are perpendicular then the product of their slopes is -1:
Equation 2:
Finally, the requested equation is:
Simply the expression below
(10-3i)(2-5i)
Answer:
7i and 3i
hope this helps <33
Answer:
Step-by-step explanation:
Use foil method
(10 - 3i) (2 -5i) = 10*2 + 10*(-5i) + (-3i)*2 + (-3i)*(-5i)
= 20 - 50i -6i + 15i²
= 20 - 50i - 6i + 15*(-1) {i² = -1}
= 20 - 50i - 6i - 15
= 20 - 15 - 50i - 6i
= 5 - 56i

What is the solution set of the equation - 52 – 15| = 10?
-
=
A {2,4}
B. {7}
CO{4}
D.{-1,7}
SIA
PLS HELP
Answer:
{-1,7}
Step-by-step explanation:
1/2 | 5x-15| = 10
Multiply each side by 2
1/2 *2 | 5x-15| = 10*2
| 5x-15| = 20
Absolute value equations have two solutions, one positive and one negative
5x-15 = 20 5x-15 = -20
Add 15 to all sides
5x-15+15 = 20+15 5x-15 +15 = -20+15
5x= 35 5x=-5
Divide by 5
5x/5 = 35/5 5x/5 = -5/5
x=7 x=-1

Parallelogram EFGH is the output of the transformation as defined below.
▱ EFGH = Ro 90° ( ▱ ABCD)
Draw ▱ EFGH
Parallelogram EFGH has vertices at E(-1, 4), F(-1, 6), G(3, 3) and H(3, 5)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If point A(x , y) rotated about the origin by angle 90°, then its image is A'(-y , x).
The parallelogram ABCD has vertices at A(4,1), B(6, 1) C(3, -3) and D(5, -3).
Hence the transformation EFGH = Ro 90° ( ▱ ABCD), gives:
E(-1, 4), F(-1, 6), G(3, 3) and H(3, 5)
Parallelogram EFGH has vertices at E(-1, 4), F(-1, 6), G(3, 3) and H(3, 5)

Answer:
0
Step-by-step explanation:
→ State the slope formula
( y₂ - y₁ ) ÷ ( x₂ - x₁ )
→ State each value
x₁ = 3, y₁ = 18, x₂ = 0 and y₂ = 18
→ Substitute in each value into the formula

Answer:
y = -2/3x + 2
have a good day :3
Step-by-step explanation:
we need to bring it into the form
y = ax + b
so,
2x + 3y = 6
3y = -2x + 6
y = (-2/3)x + 2
the slope is the factor of x (-2/3). the y-intercept is 2 (meaning y = 2 for x = 0).

Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate.
I need help on this, asap‼️
Answer:
A: 2 1/2 ft^2/h
B: 3 1/3 ft^2/h
B has the greater rate
Step-by-step explanation:
The rate in square feet per hour is found by dividing square feet by hours.
Machine A:
(5/8 ft^2) ÷ (1/4 h) = (5/8)×(4/1) ft^2/h = 5/2 ft^2/h = 2 1/2 ft²/h
Machine B:
(2/3 ft^2) ÷ (1/5 h) = (2/3)×(5/1) ft^2/h = 10/3 ft²/h = 3 1/3 ft²/h
Machine B has the greater rate.

Answer:
x = 12
perimeter = 124
Step-by-step explanation:
The midline RS is half the length of MN, so we have ...
2×RS = MN
2(x +3) = 5x -30
2x +6 = 5x -30
36 = 3x . . . . . . . . . add 30-2x
12 = x . . . . . . . . . . divide by 3
__
The length RS is then ...
RS = x +3 = 15
and the perimeter of QRS is ...
P(QRS) = QR +RS +SQ = 25 +15 +22 = 62
The perimeter of QRS is half the perimeter of MNP, so ...
P(MNP) = 2×P(QRS) = 2×62 = 124
The perimeter of ΔMNP = 124.
