What are the x- and y-intercepts for the graph of the equation y = 4 - 2x?
Select one:
X-intercept = 2; y-intercept = 4
x-intercept = -2; y-intercept = 4
x-intercept = 4; y-intercept = -2
X-intercept = 4; y-intercept = 2
Answer:
X intercept is -2
Y intercept is 4
Answer:
The first one, [tex]x[/tex]-intercept [tex]=2[/tex]; [tex]y[/tex]-intercept [tex] = 4[/tex]
Step-by-step explanation:
The [tex]x[/tex]-intercept is where [tex]y=0[/tex], so we can solve for it with the following equation:
[tex]0=4-2x→2x=4→x=2[/tex]
So the answer is the first one, but just to make sure, you can solve for the [tex]y[/tex]-intercept because their [tex]x[/tex]-values always equal to [tex]0[/tex] as well:
[tex]y=4-2(0)→y=4-0→y=4[/tex].
13.) An electrician has a piece of wire that is 3 feet long (36 inches). She needs a piece that is exactly 31.05 inches to fit perfectly in the outlet. How much wire will she have left over? *
O she needs to buy more baseboard, she doesn't have enough
O 4.95 inches
O 28.05 inches
O5.05 inches
Answer: 4.95 inches
Subtract: 36 - 31.05 = 4.95
Step-by-step explanation:
Whoever created this question hasn't done much real electrical work!
An outlet (also known as a receptacle) usually requires about 4 to 6 inches of wire within the junction box to make the connections, depending on what else may be connected in the box. We don't have to measure to 0.05 of an inch. The insulation may have to be stripped precisely to 3/8, 1/2 or 5/8 inch for connections.
The electrician used 3 feet of cable between junction boxes, and had 8 ¹/₂ inches pulled through the junction box. She needed 4 inches to connect the receptacle. How much the excess did she have to cut off?
Math questions should be realistic.

The approximated circumference of the circle is 15.7 inches. Then the correct option is C.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The diameter of the circle is 5 inches. Then the circumference will be

Solve the equation 4(h + 1.5) = -6.
h=
Answer:
h=3 is the answer
Step-by-step explanation:
The required solution to the given equation 4(h + 1.5) = -6 is
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question as:
4(h + 1.5) = -6
To solve the equation 4(h + 1.5) = -6, we need to isolate the variable "h". We can do this by performing the following steps:
First, we need to get rid of the parentheses around "h + 1.5". We can do this by multiplying everything inside the parentheses by 4:
4(h + 1.5) = 4h + 6
Next, we need to get rid of the coefficient of 4 in front of "h". We can do this by dividing both sides of the equation by 4:
4h + 6 = -6
h + 1.5 = -1.5
Finally, we can subtract 1.5 from both sides of the equation to isolate the variable "h":
h = -1.5 - 1.5
h = -3
Therefore, the value of "h" that satisfies the equation is -3.

Arithmetic, Geometric, or Neither?
Common difference, ratio, or neither?

Answer:
Arithmeticcommon difference = 7Step-by-step explanation:
First differences are ...
-38 -(-45) = 7
-31 -(-38) = 7
-24 -(-31) = 7
The first differences are constant, so this is an arithmetic sequence with a common difference of 7.
If f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to
If function f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.
Degree of polynomial is two so it will have only two solution
f(a)=0 if x=a
or
f(b)=0 if x=b
so put X=x+3
we will get
2[x+3]^2 - 3[x+3] + 4 = 2x^2 +9x +13
so if f(x+3)= 2x^2 +9x +13
