Consider the linear equation 4x+3y=19 find the value of y that makes the given ordered pair a solution to the equation (x, 5) X=
Answer:
X=1
Step-by-step explanation:
If the ordered pair of the solution is (x,5), this means that y=5
With this information, we plug in 5 for y and solve for x
4x+3(5)=19
4x+15=19
4x=4
x=1

Answer:
By definition definition a quadratic polynomial is a polynomial of degree two, the highest degree ter. is of second order.
A linear polynomial is defined by y=mx+c, the highest order is of degree 1.
If your x is raised to a fraction power then that is neither quadratic nor linear.

RT is an altitude of Triangle QRSA paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 25 pounds and each large box of paper weighs 70 pounds. A total of 21 boxes of paper were shipped weighing 1110 pounds altogether. Write a system of equations that could be used to determine the number of small boxes shipped and the number of large boxes shipped. Define the variables that you use to write the system.
Answer:Number of small boxes shipped = 8
Number of large boxes shipped = 13
Step-by-step explanation:
Step-by-step explanation:
Let x be the number of small boxes and let y be the number of large boxes
According to the first statement, a total of 21 boxes were shipped
Equation 1 will be:
x+y=21
According to 2nd statement, the total weight was 1110 and we know the weight of one small box is 25 and large box is 70
Equation 2 will be:
25x+70y=1110
Use the substitution method for solving the equation
Putting the value of x in equation 2
25(21-y) +70y =1110
525-25y+70y = 1110
45y = 585
Y=13
Putting the value of y in equation 1
x+13 = 21
X = 8
Number of small boxes shipped = 8
Number of large boxes shipped = 13

C. The y-intercept is (0, 150). Diego has $150 before buying any
games.
D. The y-intercept is (0, 150). Diego spends $150 per game.
Answer:
C. The y-intercept is (0, 150). Diego has $150 before buying any
Step-by-step explanation:
Brainlylist
The correct statement is The y-intercept is (0, 150). Diego has $150 before buying any games.
what is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
(0, 150) and ( 1, 112.50)
Now, slope= (112.50-150)/1
slope= -37.5
So, the equation of line is
y- 150= -37.5( x- 0)
y= -37.5x+ 150
Hence, The y-intercept is (0, 150). Diego has $150 before buying any
games.

ans should be well explained
Perimeter:-
[tex]\\ \sf\longmapsto 2(L+B)[/tex]
[tex]\\ \sf\longmapsto 2(40+30)[/tex]
[tex]\\ \sf\longmapsto 2(70)[/tex]
[tex]\\ \sf\longmapsto 140m[/tex]
Area
[tex]\\ \sf\longmapsto LB[/tex]
[tex]\\ \sf\longmapsto 40(30)[/tex]
[tex]\\ \sf\longmapsto 1200m^2[/tex]
= 2(Length + Breadth)
= 2(40 + 30)
= 2(70)
= 140m
Area of Rectangle:-= Length × Breadth
= 40 × 30
= 1200m^2
Therefore, The perimeter of the rectangle is 140m and the area of the rectangle is 1200m^2.
The value of y varies directly with x. If x = 3, then y = 18. What is the value
of x when y = 84
The value of x when y = 84 is 14
From the question,
The value of y varies directly with x
That is,
y ∝ x
Introducing the constant of proportionality, k
We get,
y = kx
Also, from the question
If x = 3, then y = 18
Putting these values into the equation, we can determine the value of k
[tex]y = kx[/tex]
[tex]18 = k \times 3[/tex]
Now, divide both sides by 3
[tex]\frac{18}{3}=\frac{k \times 3}{3}[/tex]
[tex]6 = k[/tex]
∴ k = 6
Now, to determine the value of x when y = 84
We will put y = 84 and the value of k =6 into the equation
[tex]y = kx[/tex]
[tex]84 = 6 x[/tex]
Divide both sides by 6
[tex]\frac{84}{6} = \frac{6x}{6}[/tex]
[tex]14 = x[/tex]
∴ [tex]x = 14[/tex]
Hence, the value of x when y = 84 is 14

The length of Chen’s office is 15.5 feet and the width is 7.8 feet. Use the formula P = 2ℓ + 2w to find the perimeter of the office.
46.6 feet
Step-by-step explanation:
P = 2ℓ + 2w
P = 2(ℓ + w)
P = 2(15.5 + 7.8)
P = 2(23.3)
P = 46.6 feet

A science class has 5 girls and 3 boys in the seventh grade and 4 girls and 4 boys in the eighth grade. The teacher randomly selects a seventh grader and an
eighth grader from the class for a competition. What is the probability that the students she selects are both boys?
Write your answer as a fraction in simplest form.
Answer:
To find the probability of picking two boys, we need to first know how many different ways she can pick the 7th and 8th grader.
There are 12 7th-graders and 8 8th-graders. So the total number of ways she can pick is:
12
×
8
=
96
To get two boys picked, there are 5 boys in the 7th-grade class and 4 in the 8th-grade class, so there are:
5

=
