The x-intercept of a function always occurs where y is equal to zero is true.
Given,
The x-intercept of a function always occurs where y is equal to zero.
We need to find whether the given statement is True or False.
What is x-intecept and y-interept?The x-intercept is the point where the line passes through the x-axis.
We need to put y = 0.
The y-intercept is the point where the line passes through the y-axis.
We need to keep x = 0.
Check the statement.
The x-intercept of a function always occurs where y is equal to zero.
This is a true statement because in order to find the x-intercept we need always keep y = 0.

The vegetable garden has 95 ripe plants. The number of tomatoes is 16 fewer than twice the number of squashes. How many of each vegetable are ripe?
Answer:
Tomatoes = 39.5
Squash = 55.5
Step-by-step explanation:
T (tomatoes) = S - 16
S + T = 95
we plug it in now
S + (S - 16) = 95
2s = 95 + 16
2s = 111
s = 55.5??
hm. Let's go with it
T = 55.5 - 16
T = 39.5
39.5 + 55.5 = 95

Which conic section is represented by the following equation?
5x^2 – x + 5y^2 – 3y + 4 = 0
circle
ellipse
parabola
hyperbola
Answer:
3 rd one
Step-by-step explanation:
The conic section represented by the given equation is Circle.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
Standard form of a circle is,
(x - h)² + (y - k)² = r²
where, (h, k) is the center of the circle and r is the radius of the circle.
Expanding, we get,
x² - 2hx + h² + y² - 2ky + k² = r²
x² - 2hx + y² - 2ky + (h² + k² - r²) = 0
The given equation is,
5x² – x + 5y² – 3y + 4 = 0
This is same as the standard form of the circle.
Hence the given equation is that of a circle.

6 A rectangular room is 2 m longer than it is
wide. Its perimeter is 70 m. If the width of
the room is w m, express its length in terms
of zo. Hence find the width of the room.
Answer:
W = 16.5 meters
Step-by-step explanation:
let w be the width and then the length is w+2
Perimeter = 70 = 2w + 2(w+2)
70 = 2w + 2w + 4
4w = 66
w = 16.5 meters
Evaluate the expression 5 (m - 2) + 10w when m = 8.4 and w= 1.25.
Based on the calculations, the evaluation of the given mathematical expression is 44.5.

Sudha earns ` 189 in a day and Radha earns ` 112 in a day. About how much will each of them earn in 30 days
Answer:
the sudha and radha earns 5,670 and 3,360 respectively
Step-by-step explanation:
Since in the question it is mentioned that
Sudha earns 189 in a day
And, radha earns 112 in a day
so in 30 days, sudha earns
= 189 × 30 days
= 5,670
And, radha earns
= 112 × 30 days
= 3,360
Therefore the sudha and radha earns 5,670 and 3,360 respectively
