The zeros of the function y = -5x - 7 is at x = -7/5
Linear equationA linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Given the equation:
y = -5x - 7
The zeros of the function is at y = 0, hence:
0 = -5x - 7
-5x = 7

Maggie has $16 to spend on lunch for the week she has already spent four dollars which inequality statement shows how much more money Maggie has left to spend for the week
Answer:
x ≤ $12
Step-by-step explanation:
Since Maggie has $16 to spend for the week, she can spend less than $16 or exactly $16. Thus, the inequality used would be ≤, which can be read as 'less than or equal to'.
Let the amount of money she has left to spend for the week be x.
Total spending for the week ≤ $16
$4 +spending for the rest of the week ≤ $16
$4 +x ≤ $16
Subtract both sides by $4:
x ≤ $16 -$4
x ≤ $12

Find the least common denominator. Then express each fraction using the least common denominator.
5/12 and 4/18
Answer:
5/12 = 15/364/18 = 8/36Step-by-step explanation:
The least common denominator can be found as the product of the denominators, divided by their greatest common factor:
LCD = (12)(18)/6 = 36
This is 3 times 12, so
5/12 = (5/12)(3/3) = 15/36
and it is 2 times 18, so
4/18 = (4/18)(2/2) = 8/36
The two fractions are ...

Answer:
Step-by-step explanation:
y² = 5.66 × 5.66 ⇒ y = 5.66
x = z = 5.66√2 ≈ 8.00
The values of x, y and z in the given triangle are 8, 5.66 and 8.
What are triangles?Triangles are a type of a polygon having three sides and angles.
Given is a triangle, having some unknown variables, we need to find their values,
So,
According to the figure we can say that the triangle is an isosceles triangle because the median is perpendicular to the base and dividing it into equal parts.
Therefore,
y² = 5.66 × 5.66 ⇒ y = 5.66
x = z = 5.66√2 ≈ 8.00
Hence, the values of x, y and z in the given triangle are 8, 5.66 and 8.
