find the x and y intercepts of the linear equation 2x - 4y = -20
Answer:
see explanation↓
Step-by-step explanation:
We are given the following equation of a line:
[tex]2x-4y=-20[/tex]
To determine the x-intercept we must set "y = 0":
[tex]2x-4(0)=-20[/tex]
[tex]2x=-20[/tex]
Now, we divide both sides by 2:
[tex]x=-\frac{20}{2}=-10[/tex]
Therefore, the "x" intercept is -10.
To determine the y-intercept we set "x = 0":
[tex]2(0)-4y=-20[/tex]
[tex]-4y=-20[/tex]
Now, we divide both sides by -4:
[tex]y=\frac{-20}{-4}=5[/tex]
Therefore the y-intercept is 5.
Solve by factorising.
x² - 7x+10=0
Answer:
x²-7x+10=0
x²-5x-2x+10=0
x(x-5)-2(x-5)=0
(x-2)(x-5)=0 ANS!
Step-by-step explanation:
First we will multiply x² into 10, the answer will be 10x². Now, take L.C.M of 10, the L.C.M will be 5x2 or 2x5. Now we will make sure that:
2x x 5x=10x² while 5x+2x=7x. Now, we know that 7x is in negative so, we will change the signs and it will become x²-5x-2x+10=0. Now take common:
x(x-5)-2(x-5)=0. Now, write the common taken numbers first and then the other brackets in last i.e: (x-2)(x-5)=0

Find the exact circumference of a circle with a diameter of 5 inches.
The circumference is
inches.
Answer:
15.7 in
Step-by-step explanation:
You can use the below formula to find the circumference of the circle.
C = π × d
Here,
d ⇒ diameter ⇒ 5 in
Let us find it now.
C = π d
C = 3.14 × 5
C = 15.7 in
Answer:
The exact diameter is 15.707963267948966192313216916398 inches multiplied by full form of pi.
________________________________________________________
SolveSet C as your substitute for circumference.
[tex]C =[/tex]
Now that we have this, we need to assign a value of pi long form followed by the diameter, which is 5 inches².
[tex]C = \pi d[/tex]
[tex]d = 5[/tex]
Lastly, ignore C, and multiply pi by the diameter, d.
[tex]\pi * d = 15.707963267948966192313216916398[/tex] without rounding

In the triangle shown, the ratio of the height to the length of the base is 3:4.
Chose True or False on A-C.
A. The area of the triangle is twice the area of a parallelogram with the same base and height
B. The height is 3/4 the base length.
C. The area is 8.64 mm²
Answer:
A. False
B. True
C. True
Step-by-step explanation:
A: Area of traingle = 1/2 × Base Length × Height
Area of parallelogram = Base Length × Height
Therefore, Statement A is False.
B: Base on the ratio for height to base length 3:4,
Statement B is True.
C: Base Length = 4.8 ÷ 4 × 3
= 3.6 mm
Area of Triangle = 1/2 × Base Length × Height
= 1/2 × 3.6 × 4.8
= 8.64mm²
Therefore, Statement B is True.
determine if - 2r + 6r^5 + sr is a polynomial or not. if it is a polynomial, state the type and degree of the polynomial
The polynomial, - 2r + 6r^5 + sr is a trinomial.
The degree of the polynomial is 5.
What is a Polynomial?A polynomial can be defined as an algebraic expression that consists of constants, variables, and positive exponents.
The degree of a polynomial is dependent on the highest exponent value carried by any of the terms. Also, the number of terms a polynomial has determines what type of polynomial it is.
Given the polynomial, - 2r + 6r^5 + sr:
It has three terms, therefore, it is a trinomial.
The degree of the polynomial is 5.

25% of z is 150. Find the value of z.
(Can y’all show your work on this so I know how you got it)
Answer:
z = 600
Step-by-step explanation:
Method 1 - ratios
If 150 is 25% then z is 100%:
[tex]\begin{aligned} 150 : 25 & = z : 100\\\dfrac{150}{25} & = \dfrac{z}{100}\\150 \cdot 100 & = 25z\\15000 & = 25z\\z & = \dfrac{15000}{25}\\z & = 600 \end{aligned}[/tex]
Method 2
Calculate the amount for 1%, then multiply by 100% to find z:
25% = 150
⇒ 1% = 150 ÷ 25 = 6
⇒ z = 100% = 6 x 100 = 600

Which choice describes an equation
that has a solution set of
"All real numbers"?
3(x + 1) = 3x + 3
Answer:
Step-by-step explanation:
Remark
Choose any number at all and see what happens.
Suppose x = 8
3*(8 + 1) = 3*8 + 3
3(9) = 27
3*8 + 3 = 24 + 3 = 27
What you have shown is that the second choice is incorrect. There is at least one value that makes the equation correct (that is, both sides come to the same result.)
If choice two is false then choice one must be true since these results may give the only 2 possible results.

Milk is on sale for 40% off when it is normally $3.75 per gallon. How much will a gallon of milk cost?
The discounted price for milk is $_____(Round to the nearest cent.)
Answer:
$2.25 is the discounted price for each gallon.
Step-by-step explanation:
So you take 40% and convert it into decimal form, which is 0.4. Then you take $3.75 x 0.4 = 1.5. Then subtract $1.50 from $3.75, and that equals $2.25 each gallon.

What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, the line is parallel to 8x + 3y =15, hence the slope is given by:
[tex]m = -\frac{8}{3}[/tex]
It passes through the point (6, -1), hence:
y = mx + b
[tex]-1 = -\frac{8}{3} \times 6 + b[/tex]
b = 15
Hence:
[tex]y = -\frac{8}{3}x + 15[/tex]
In standard form:
[tex]\frac{8}{3}x + y = 15[/tex]
