Answer:
y=9.25
Step-by-step explanation:
5x+2y=20
5(.3)+2y=20
1.5+2y=20
2y=20-1.5
2y=18.5
y=18.5/2
y=9.25
Write an equation that represents the line?

Respuesta:
1/2; 4/3; 5/3; 1/4; 1/6; 4/7
Explicación paso a paso:
1.)
4/6 * 3/4
= 24/12
= 1/2
2.) 14/5 * 10/21
= 2/1 * 2/3
= 4/3
3.)

Answer:
see below
Step-by-step explanation:
The x-values in each table are evenly-spaced (increasing by 2). So, the quadratic function can be identified by its second differences: they will be a non-zero constant.
Table 1 has first differences that are constant at 3. -2-(-5) = 3, for example. It represents a linear function.
Table 2 has first differences of 4, 8, 4, 4, neither constant, nor linearly increasing. The function does not have a name.
Table 3 has first differences of -9, -3, +3, +9, and these have differences of +6. This represents a quadratic function.
Table 4 has first differences of 0.5, 1, 2, 4. These have a constant ratio, as do the values in the table. It represents an exponential function.
The table that represents a quadratic function is C. Table 3.
What is a quadratic function?A quadratic function simply means a function that's in the form of f(x) = ax² + bx + c.
In this case, the table that represents a quadratic function is table 3. It has first differences of -9, -3, +3, +9, and these have differences of +6. It can be deduced that in the quadratic function, b and x are numbers.

Answer:
60
Step-by-step explanation:
<C+<D = 180 since they form a straight line
5x+20 +3x = 180
8x+20 = 180
Subtract 20 from each side
8x+20-20 = 180-20
8x = 160
Divide by 8
8x/8 = 160/8
x = 20
We want to find angle D
<D = 3x= 3*20 = 60
What is the value of b in the equation 3b - 4 = 11?
Answer:
b = 5
Step-by-step explanation:
3b - 4 = 11
Add 4 to each side
3b - 4+4 = 11+4
3b = 15
Divide each side by 3
3b/3 = 15/3
b = 5
Answer:
b = 5
Step-by-step explanation:
3b - 4 = 11
3b - 4 + 4 = 11 + 4
3b = 15
3b ÷ 3 = 15 ÷ 3
b = 5
Pablo drove 715 miles in 11 hours.
At the same rate, how many miles would he drive in 9 hours?
Answer:
585 miles
Step-by-step explanation:
divide 715 by 11 so that you can see the mph (miles per hour). Then multiply that number by 9 for the amount of miles he would travel in nine hours
715/11=65
65x9=585

Step-by-step explanation:
distance is the speed of the moving object multiplied by the time taken to complete a certain distance therefore the speed is the distance covered divided by the time taken.
Sarah completes 1/6 of a project in 1/4 of an hour at this rate how much of the project does Sarah complete per hour? Sarah completes blank of the project per hour.
Answer:
2/3
Step-by-step explanation:
Time it would take Sarah to complete the work in one hour = work completed in 1/4 hours x 4
We are multiplying by 4 because there are 4, 1/4 in an hour
1/4 + 1/4 + 1/4 + 1/4 = 1 hour

SkippingSkippingAngles A and EAngles B and CAngles D and EAngles A and HAngles A and BAngle AAngle BAngles E and F=====================================
Explanation:
SkippingSkippingCorresponding angles are ones where they are in the same configuration of the 4 corner angle set up. Angles A and E are in the same northwest position. Another pair would be angles B and F in the northeast, and so on. Corresponding angles are congruent when we have parallel lines like this.Vertical angles form when we cross two lines. They are opposite one another and always congruent (regardless if the lines are parallel or not).Alternate interior angles are inside the parallel lines, and they are on alternating sides of the transversal cut. Alternate interior angles are congruent when we have parallel lines like this. Alternate exterior angles are the same idea as number 5, but now we're outside the parallel lines. Alternate exterior angles are congruent when we have parallel lines like this.Adjacent angles can be thought of as two rooms that share the same wall. Specifically, adjacent angles are two angles that share the same segment, line, or ray. The angles must also share the same vertex. In this case, any pair of adjacent angles always adds to 180 (though it won't be true for any random pair of adjacent angles for geometry problems later on).Simply list any angle that looks obtuse, ie any angle that is larger than 90 degrees.List any angle that is smaller than 90 degrees. It can be adjacent to whatever you picked for problem 8, but it could be any other acute angle as well.Refer to problem 7. In this case, adding any two adjacent angles together forms a straight line.please help me ill give you 10 points

What are the types of representing data?Data refers to the elements that make up persons, things, events, and ideas. It could be an integer, a title, or anycast. Data must be tabulated after collection in order to study their prominent characteristics. The presentation of data is the name given to such a configuration.

Answer:
Step-by-step explanation:
Expression on the board :
[tex]12.2x + 50.6 y + 3(1.4x - 2.6y)\\\\= 12.2x + 50.6y + 4.2x - 7.8y\\\\= 16.4x + 42.8y[/tex]
Expression by the student :
Expression 1 :
[tex]4 ( 4.1x + 10.7 y ) \\\\= ( 4 \times 4.1x ) + ( 4 \times 10.7 y)\\\\= 16.4x + 42.8y\\\\[/tex]
The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.
Expression 2 :
[tex]2 ( 6.1x + 25.3 y + 2.1x -3.9y)\\\\= 2 ( 8.2x + 21.4y)\\\\=( 2 \times 8.2x ) + (2 \times 21.4y)\\\\= 16.4x + 42.8y[/tex]
The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.
