Solve the system using elimanation: 3x + 5y = -2 and -x + 2y = 8
Answer:
Step-by-step explanation:
3x+5y+3(-x+2y)=-2+3(8)
3x+5y-3x+6y=-2+24
11y=22
y=2, using this y in -x+2y=8 gives you
-x+2(2)=8
-x+4=8
-x=4
x=-4
So the solution is the point (x, y)=(-4, 2)

what is the measure of y
Answer:
y = 156 degrees
Step-by-step explanation:
90-66=24
180-24= 156
Answer:
y is 156°.
Step-by-step explanation:
We know ∠FED is 66°, and ∠FED & ∠DEB (or z) equal 90° degrees. That means ∠z is 24° degrees as is ∠x, since it is adjacent to ∠z. ∠x and ∠y are supplementary, which meant they equal 180°. Subtract 24° (∠x's measurement ) from 180° to get your final answer of y being 156°.

What is the distance between the points (-1,5) and (8,5) in the coordinate plane? OA. 6 OB. 9 OC. 12 OD. 7
Answer:
The answer is 9
Step-by-step explanation:
If you subtract 8-(-1) you would get 9.
The distance between the points (-1,5) and (8,5) in the coordinate plane is 9 option (B) is correct.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have two points (-1,5) and (8,5):
[tex]\rm d=\sqrt{(8+1)^2+(5-5)^2}[/tex]
d = 9
Thus, the distance between the points (-1,5) and (8,5) in the coordinate plane is 9 option (B) is correct.

Write an equation in slope-intercept form for a line that passes through the point (1, 6) and
has a slope of 2
Answer:
y=2x+4
Step-by-step explanation:
If the line has a slope of two, that means it goes up 2 on the y axis for every 1 on the x axis. So, if it goes through (1,6), then you can subtract 1 from the x axis and two from the y axis to find the y intercept, (0,4).
Maya is solving the equation 2(1+7x)=72. She lists an explanation for each step as shown. Which is the missing explanation for Maya's first step after writing the given equation?
Answer:
x = 5
Step-by-step explanation:
The given equation is :
2(1+7x)=72
Use the distributive property to the LHS.
2(1)+2(7x) = 72
2+14x = 72
Subtract 2 from both sides.
2+14x-2 = 72-2
14x = 70
x = 70/14
x = 5
So, the answer of the given equation is x = 5.

Step-by-step explanation:
Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less
than 140.
The value of x for which the perimeter of the rectangle is less than 140 is,
x ≤ 33.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
A rectangular shape with sides x + 4 and x.
And the perimeter of the rectangle is less than 140.
That means,
2(2x + 4) ≤ 140
4x + 8 ≤ 140
4x ≤ 140 -8
4x ≤ 132
x ≤ 33
Therefore, the solution of the inequality is x ≤ 33.

On a bicycle trail, the city is painting arrows like the one shown below:
Calculate the area of the arrow by decomposing it into rectangles and triangles. (4 points)
Group of answer choices
148.5 square centimeters
151.5 square centimeters
171 square centimeters
195 square centimeters
Its confusing
Answer:
151.5 cm^2
Step-by-step explanation:
lets cut stright acrros so you have a triangle 13 (base) by 3 cm (high)
area of a triangle is 1/2 base times hight --> 13x3/2 = 19.5cm^2
now lets doi the rectangle that is 12 by 11
Length times hight is the area is 132
add both areas 132 + 19.5
